treatment | What are the treatments for Parsonage Turner syndrome ? | How might Parsonage Turner syndrome be treated? Treatment for Parsonage Turner syndrome (PTS) varies based on the signs and symptoms present in each person. For example, pain medications may be prescribed depending on the severity of the nerve pain. Other techniques for pain management include application of heat or cold and transcutaneous electrical nerve stimulation (a method of pain relief in which a special device transmits low-voltage electrical impulses through electrodes on the skin to an area of the body that is in pain). Many affected people undergo physical therapy and/or occupational therapy to maintain muscle strength and range of motion of affected joints once the pain begins to subside. Surgeries to restore movement and function to the shoulder muscles and joint may be considered if other treatment options are not effective. |

information | What is (are) Tietze syndrome ? | Tietze syndrome is an inflammatory condition characterized by chest pain and swelling of the cartilage that joins the upper ribs to the breastbone (costochondral junction). Signs and symptoms of this condition usually develop in young adults (before age 40) and include mild to severe chest pain that may extend into the arms and/or shoulders. The cause of this condition is unknown. In some cases, Tietze syndrome may resolve on its own without treatment. Management for others may include minimizing physical activity; applying local heat; and taking pain medications and/or nonsteroidal anti-inflammatory drugs. Of note, this syndrome is different from Tietz syndrome, which is characterized by profound hearing loss from birth, fair skin, and light-colored hair. |
symptoms | What are the symptoms of Tietze syndrome ? | What are the signs and symptoms of Tietze syndrome? The signs and symptoms of Tietze syndrome usually develop in young adulthood (before age 40). The most common symptom is mild to severe chest pain that may extend into the arms and/or shoulders. The onset of pain can be gradual or sudden and may worsen with coughing, sneezing, or deep breathing. More than 70% of cases occur on only one side (unilateral) and affect one joint. The affected joint is typically tender and swollen. While the pain associated with Tietze syndrome usually subsides after several weeks or months, the swelling may persist. |
causes | What causes Tietze syndrome ? | What causes Tietze syndrome? The exact underlying cause of Tietze syndrome is currently unknown. Some researchers have speculated that small injuries to the anterior chest wall may contribute to the development of the condition. |
inheritance | Is Tietze syndrome inherited ? | Is Tietze syndrome inherited? Tietze syndrome is not thought to be inherited. Most cases occur sporadically in people with no family history of the condition. |
exams and tests | How to diagnose Tietze syndrome ? | How is Tietze syndrome diagnosed? Tietze syndrome is a diagnosis of exclusion. This means that a diagnosis is made in people with chest pain and swelling of the cartilage that joins the upper ribs to the breastbone (costochondral junction) after other conditions with similar signs and symptoms have been ruled out. A thorough physical exam and various tests (i.e. electrocardiogram, x-ray, CT scan) may be necessary to exclude other conditions. |
treatment | What are the treatments for Tietze syndrome ? | How might Tietze syndrome be treated? In some individuals, the pain associated with Tietze syndrome resolves on its own without any treatment. Management options for others may include avoidance of strenuous activity; applying local heat; taking pain medications and/or nonsteroidal anti-inflammatory drugs; and receiving local corticosteroid injections. Although the pain usually subsides after several weeks or months, swelling may persist. |
information | What is (are) Geniospasm ? | Hereditary geniospasm is a movement disorder that causes episodes of involuntary tremors of the chin and lower lip. The episodes may last anywhere from a few seconds to hours and may occur spontaneously or be brought on by stress. The episodes usually first appear in infancy or childhood and tend to lessen in frequency with age. Hereditary geniospasm is believed to be inherited in an autosomal dominant pattern. Although the exact gene(s) that cause the condition are unknown, it has been suggested that mutations in a gene on chromosome 9 may be responsible in some families. |
symptoms | What are the symptoms of Geniospasm ? | What are the signs and symptoms of Geniospasm? The Human Phenotype Ontology provides the following list of signs and symptoms for Geniospasm. If the information is available, the table below includes how often the symptom is seen in people with this condition. You can use the MedlinePlus Medical Dictionary to look up the definitions for these medical terms. Signs and Symptoms Approximate number of patients (when available) Autosomal dominant inheritance - Chin myoclonus - The Human Phenotype Ontology (HPO) has collected information on how often a sign or symptom occurs in a condition. Much of this information comes from Orphanet, a European rare disease database. The frequency of a sign or symptom is usually listed as a rough estimate of the percentage of patients who have that feature. The frequency may also be listed as a fraction. The first number of the fraction is how many people had the symptom, and the second number is the total number of people who were examined in one study. For example, a frequency of 25/25 means that in a study of 25 people all patients were found to have that symptom. Because these frequencies are based on a specific study, the fractions may be different if another group of patients are examined. Sometimes, no information on frequency is available. In these cases, the sign or symptom may be rare or common. |
inheritance | Is Geniospasm inherited ? | How is hereditary geniospasm inherited? Hereditary geniospasm is inherited in an autosomal dominant manner. This means that having only one mutated copy of the causative gene in each body cell is sufficient to cause signs and symptoms of the condition. When an individual with an autosomal dominant condition has children, each child has a 50% (1 in 2) chance to inherit the mutated copy of the gene and also be affected. Because there is a 50% chance for each child, it is possible for all of the children of an affected individual to be affected, or likewise, for all of the children to be unaffected. |
exams and tests | How to diagnose Geniospasm ? | How might hereditary geniospasm be diagnosed? Although we were unable to locate laboratories offering genetic testing for hereditary geniospasm, the condition can be diagnosed on the basis of a clinical evaluation performed by a health care professional such as a neurologist who specializes in movement disorders. |
treatment | What are the treatments for Geniospasm ? | How might hereditary geniospasm be treated? Hereditary geniospasm, which may also be referred to as hereditary essential chin myoclonus, is generally considered a benign disorder although in some cases it can cause anxiety and social embarrassment. Significant improvement with age has been reported. Several drugs are used to treat myoclonus, such as benzodiazepines and anticonvulsants. However, individuals may not respond to a single medication and may experience significant side effects if a combination of drugs is used. It has also been suggested that botulinum toxin be considered as a primary treatment because it has been shown to be effective and well tolerated. |

information | What is (are) Pityriasis rubra pilaris ? | Pityriasis rubra pilaris (PRP) refers to a group of skin conditions that cause constant inflammation and scaling of the skin. Affected people have reddish-orange colored patches; they may occur everywhere on the body or only on certain areas. There are several types of PRP, which are classified based on age of onset, body areas affected, and whether other associated conditions are present. PRP is usually sporadic (occurring randomly) but some forms may be inherited. |
symptoms | What are the symptoms of Pityriasis rubra pilaris ? | What are the signs and symptoms of Pityriasis rubra pilaris? Features of this condition vary greatly between affected individuals. The onset is gradual in the familial type and can be more rapid in the acquired type. Redness and scaling of the face and scalp are often seen first, followed by redness and thickening of the palms and soles. Overall, the elbows, knees, backs of the hands and feet, and ankles are most commonly affected. A more widespread eruption consisting of scaling orange-red plaques can be observed on the trunk and extremities. The lesions may expand and coalesce and eventually cover the entire body. When the disease becomes widespread, the nails, mucous membranes and eyes may be affected. The familial type often persists throughout life, but the acquired form may have periods of remission (periods of time where symptoms improve or completely resolve). The Human Phenotype Ontology provides the following list of signs and symptoms for Pityriasis rubra pilaris. If the information is available, the table below includes how often the symptom is seen in people with this condition.

In these cases, the sign or symptom may be rare or common. |
causes | What causes Pityriasis rubra pilaris ? | What causes pityriasis rubra pilaris? In most cases, pityriasis rubra pilaris (PRP) occurs sporadically for unknown reasons. In a few families with the inherited form, familial PRP, the condition is caused by mutations in the CARD14 gene. This gene gives instructions for making a protein that turns on other proteins that regulate genes that control the body's immune responses and inflammatory reactions. It also protects cells from certain signals that would otherwise cause them to self-destruct. The CARD14 protein is particularly abundant in the skin. Mutations in the gene can cause a person to have an abnormal inflammatory response. Researchers are trying to find out how these mutations cause the specific features of familial PRP. |
treatment | What are the treatments for Pityriasis rubra pilaris ? | How might pityriasis rubra pilaris be treated? Treatment of pityriasis rubra pilaris (PRP) is mainly based on reports of patients' experiences. No controlled trials have been done, so the effectiveness and safety of treatments is unclear. Currently there are no treatments approved by the US Food and Drug Administration (FDA) or the European Medicines Agency (EMA) for use in PRP. Management of PRP often involves systemic and topical therapies combined. Topical therapies can help with the symptoms and may be enough for people with mild PRP. Topical treatments are usually combined with systemic therapy for PRP that affects a large part of the body. Most people need systemic therapy to control the condition. Oral retinoids (synthetic vitamin A derivatives) are usually preferred as a first-line systemic treatment for PRP. Methotrexate may be an alternative option for people who should not use systemic retinoids, or who don't respond to systemic retinoid therapy. For people who don't respond well to retinoid or methotrexate therapy, options may include biologic TNF-alpha inhibitors, azathioprine, cyclosporine, and/or phototherapy. Topical treatments used for PRP may include topical corticosteroids, keratolytics, tar, calcipotriol, topical tretinoin, and tazarotene. Some of the medications used to treat PRP can harm a developing fetus and are not recommended for use right before or during pregnancy. People seeking information about specific treatment options for themselves or family members should speak with their health care provider. |

information | What is (are) Limited systemic sclerosis ? | Systemic sclerosis ine scleroderma is a type of systemic scleroderma that is characterized by Raynaud's phenomenon and the buildup of scar tissue (fibrosis) on one or more internal organs but not the skin. While the exact cause of sine scleroderma is unknown, it is believed to originate from an autoimmune reaction which leads to the overproduction of collagen (a tough protein which normally strengthens and supports connective tissues throughout the body). When fibrosis affects internal organs, it can lead to impairment or failure of the affected organs. The most commonly affected organs are the esophagus, heart, lungs, and kidneys. Internal organ involvement may be signaled by heartburn, difficulty swallowing (dysphagia), high blood pressure (hypertension), kidney problems, shortness of breath, diarrhea, or impairment of the muscle contractions that move food through the digestive tract (intestinal pseudo-obstruction). |

information | What is (are) Norrie disease ? | Norrie disease is an inherited eye disorder that leads to blindness in male infants at birth or soon after birth. Additional symptoms may occur in some cases, although this varies even among individuals in the same family. Most affected individuals develop sensorineural hearing loss and many exhibit cognitive abnormalities such as developmental delays, behavioral issues, or psychotic-like features. Norrie disease is caused by mutations in the NDP gene. It is inherited in an X-linked recessive pattern. Treatment is directed toward the specific symptoms present in each individual. The coordinated efforts of a team of specialists, including pediatricians, ophthalmologists, and audiologists may be needed. Early intervention and special education services are important to ensure that children with Norrie disease reach their full potential. |

causes | What causes Norrie disease ? | What causes Norrie disease? Norrie disease is caused by a change (mutation) in the NDP gene, which is located on the X chromosome. It is inherited in an X-linked recessive manner. The NDP gene provides instructions for making a protein called norrin, which affects the way cells and tissues develop. In particular, the norrin protein seems to play an important role in the development of retinal cells in the eye. It is also involved in creating a blood supply to tissues of the retina and the inner ear, and the development of other body systems. Mutations in the NDP gene can prevent the norrin protein from working correctly, resulting in the signs and symptoms of Norrie disease. |
treatment | What are the treatments for Norrie disease ? | How might Norrie disease be treated? Because most males with Norrie disease (ND) have complete retinal detachment at the time of birth, surgical intervention after that time is typically not effective for preserving sight. Furthermore, we were unable to find reports about restoring sight to affected individuals after sight has been lost. Individuals without complete retinal detachment may benefit from intervention; however, vitrectomy and laser photocoagulation are reportedly challenging and often associated with poor outcome. A more recent case report reported evidence that immediate, prophylactic laser treatment at birth may prevent retinal detachment and blindness. The individual described in the study was known to be at risk and was diagnosed before birth via amniocentesis, and thus laser treatment shortly after birth was able to be performed. The authors of this report state that although the results they achieved are encouraging, longer observation of a larger number of patients is needed to determine the effectivness of this new approach. In some cases, surgery may be required when progression of the condition leads to increased pressure within the eye. Rarely, enucleation (removal) of the eye may be necessary to control pain. For individuals with hearing loss, hearing aid augmentation is usually successful until middle or late adulthood. Cochlear implants may be considered when function is severely impaired. |
information | What is (are) Alagille syndrome ? | Alagille syndrome is an inherited disorder in which a person has fewer than the normal number of small bile ducts inside the liver. It is a complex disorder that can affect other parts of the body including the heart, kidneys, blood vessels, eyes, face, and skeleton. Symptoms, including jaundice, pale, loose stools, and poor growth, typically develop in the first 2 years of life. Symptoms and symptom severity varies, even among people in the same family. Alagille syndrome is caused by mutations in the JAG1 and NOTCH2 genes. It is inherited in an autosomal dominant pattern. Treatment is symptomatic and supportive. In severe cases, liver transplant may be necessary. |
symptoms | What are the symptoms of Alagille syndrome ? | What are the signs and symptoms of Alagille syndrome? Alagille syndrome is a complex multisystem disorder involving the liver, heart, eyes, face, and skeleton. Symptoms typically present in infancy or early childhood. The severity of the disorder varies among affected individuals, even within the same family. Symptoms range from so mild as to go unnoticed to severe enough to require heart and/or liver transplants. One of the major features of Alagille syndrome is liver damage caused by abnormalities in the bile ducts. These ducts carry bile (which helps to digest fats) from the liver to the gallbladder and small intestine. In Alagille syndrome, the bile ducts may be narrow, malformed, and reduced in number. This results in a build-up of bile causing scarring that prevents the liver from working properly. This may lead to jaundice, itchy skin, and deposits of cholesterol in the skin (xanthomas). Alagille syndrome is also associated with several heart problems, including impaired blood flow from the heart into the lungs (pulmonic stenosis). Other heart-related problems include a hole between the two lower chambers of the heart (ventricular septal defect) and a combination of heart defects called tetralogy of Fallot. People with Alagille syndrome may also have distinctive facial features (including a broad, prominent forehead; deep-set eyes; and a small, pointed chin), problems with the blood vessels within the brain and spinal cord (central nervous system) and the kidneys, and an unusual butterfly shape of the bones of the spinal column (vertebrae). Detailed information about the symptoms associated with Allagille syndrome can be accessed through the National Digestive Diseases Information Clearinghouse (NDDIC) and GeneReviews. The Human Phenotype Ontology provides the following list of signs and symptoms for Alagille syndrome.

causes | What causes Schnitzler syndrome ? | What causes Schnitzler syndrome? The exact underlying cause of Schnitzler syndrome is currently unknown. People affected by this condition often have a blood abnormality called monoclonal gammopathy, a condition in which the body over-produces certain immunoglobulins (typically immunoglobulin M). Immunoglobulins are proteins that are made by certain white blood cells. They play a role in the immune response by helping destroy bacteria, viruses, and other substances that appear foreign and harmful. Some researchers believe that the abnormal accumulation of immunoglobulins in the skin and other parts of the body may play a role in the development of the signs and symptoms of Schnitzler syndrome. Other scientists speculate that alterations in cytokines may play a role in the development of Schnitzler syndrome. Cytokines are specialized proteins that play an important role in the immune response. They are secreted by certain immune system cells and play a vital role in controlling the growth and activity of other immune system cells. Abnormal findings involving a specific cytokine called interleukin-1 have been found in some people with Schnitzler syndrome. |
exams and tests | How to diagnose Schnitzler syndrome ? | How is Schnitzler syndrome diagnosed? A diagnosis of Schnitzler syndrome is often suspected based on the presence of characteristic signs and symptoms identified through physical exam, laboratory studies (i.e. immunoelectrophoresis) and/or imaging studies. Additional testing should also be ordered to rule out other conditions that cause similar features. Medscape Reference's Web site offers more specific information on the diagnosis of Schnitzler syndrome. Please click on the link to access this resource. |
treatment | What are the treatments for Schnitzler syndrome ? | How might Schnitzler syndrome be treated? The treatment of Schnitzler syndrome is aimed at alleviating the signs and symptoms associated with the condition. The following medications have been used with variable success: Nonsteroidal anti-inflammatory drugs (NSAIDs) Corticosteroids Immunosuppressive agents Interleukin-1 receptor antagonists (medications that inhibit the cytokine IL-1) Colchicine Dapsone Thalidomide Rituximab Some studies suggest that phototherapy may improve the rash in some affected people.

inheritance | Is Osteomesopyknosis inherited ? | How is osteomesopyknosis inherited? Osteomesopyknosis is inherited in an autosomal dominant manner. This means that having only one mutated copy of the responsible gene (which has not yet been identified) is enough to cause signs or symptoms of the disorder. When a person with an autosomal dominant condition has children, each child has a 50% (1 in 2) risk to be affected. There have been reported cases where both parents of an affected person did not appear to have the condition. The chance of having signs and symptoms when the responsible mutation is present (penetrance), and potential nature of signs and symptoms (expressivity), is not clear. |

information | What is (are) Autosomal recessive pseudohypoaldosteronism type 1 ? | Autosomal recessive pseudohypoaldosteronism type 1 is a disorder of electrolyte metabolism characterized by excess loss of salt in the urine and high concentrations of sodium in sweat, stool, and saliva. The disorder involves multiple organ systems and is especially dangerous in the newborn period. Laboratory tests may show hyponatremia, hyperkalemia, and increased plasma renin activity with high levels of aldosterone in the blood. Respiratory tract infections are common in affected children. Treatment involves aggressive salt replacement and control of hyperkalemia. The disorder may become less severe with age. Autosomal recessive pseudohypoaldosteronism type 1 (PHA1B) is transmitted in an autosomal recessive manner and is caused by mutations in the genes coding for the subunits of the amiloride-sensitive sodium channel (SCNN1A, SCNN1B and SCNN1G). |

information | What is (are) MECP2 duplication syndrome ? | MECP2 duplication syndrome is a genetic condition that occurs almost exclusively in males and is characterized by moderate to severe intellectual disability. Other signs and symptoms include infantile hypotonia; delayed motor milestones (i.e. sitting up, crawling); recurrent infections; poor or absent speech; seizures; and/or spasticity. MECP2 duplication syndrome occurs when there is an extra copy (duplication) of the MECP2 gene in each cell. This is generally caused by a duplication of genetic material located on the long (q) arm of the X chromosome. The condition is inherited in an X-linked manner. Treatment is based on the signs and symptoms present in each person. |
symptoms | What are the symptoms of MECP2 duplication syndrome ? | What are the signs and symptoms of MECP2 duplication syndrome? MECP2 duplication syndrome is a condition that occurs almost exclusively in males and is characterized by moderate to severe intellectual disability. Infants affected by this condition are generally diagnosed with severe hypotonia within the first few weeks of life. This reduced muscle tone can lead to feeding difficulties which may require a feeding tube. Trouble swallowing, gastroesophageal reflux, failure to thrive, and extensive drooling are also common symptoms. Distinctive physical features may be noticed shortly after birth which can include brachycephaly (abnormally flat back of the head), midface hypoplasia (underdevelopment of the middle of the face), large ears, deep-set eyes, prominent chin, and a depressed nasal bridge. Due to hypotonia, affected children often have delayed development of motor milestones such as sitting up and crawling. Approximately, one third of affected people never walk independently and those who are able to walk may have an abnormal gait (style of walking). In most cases, hypotonia gives way to spasticity during childhood. Progressive spasticity, which is generally more pronounced in the legs, may lead to the development of mild contractures. Consequently, many affected adults require the use of a wheelchair. The majority of affected people do not develop the ability to talk. Some may have limited speech during early childhood, but frequently this ability is progressively lost during adolescence. Other signs and symptoms associated with MECP2 duplication syndrome may include seizures; autistic features; clinically significant constipation and bladder dysfunction. Many people affected by MECP2 duplication syndrome have recurrent respiratory tract infections. These respiratory infections can be life-threatening and as a result, approximately half of affected people succumb by age 25. In most cases, females with a duplication of the MECP2 gene do not have any symptoms, although depression, anxiety, and autistic features have been described in some. When affected, women with MECP2 duplication syndrome are generally less severely affected than males with the condition. The Human Phenotype Ontology provides the following list of signs and symptoms for MECP2 duplication syndrome.

causes | What causes MECP2 duplication syndrome ? | What causes MECP2 duplication syndrome? MECP2 duplication syndrome occurs when there is an extra copy (duplication) of the MECP2 gene in each cell. This is generally caused by a duplication of genetic material located on the long (q) arm of the X chromosome. The size of the duplication can vary; however, this does not appear to affect the severity of the condition. People with larger duplications have signs and symptoms that are similar to people with smaller duplications. The MECP2 gene encodes a protein that is important for normal brain functioning. Although it plays many roles, one of its most important functions is to regulate other genes in the brain by switching them on and off. A duplication of the MECP2 gene leads to the production of excess protein, which is unable to properly regulate the expression of other genes. This results in irregular brain activity, leading to the signs and symptoms of MECP2 duplication syndrome. |
inheritance | Is MECP2 duplication syndrome inherited ? | Is MECP2 duplication syndrome inherited? MECP2 duplication syndrome is inherited in an X-linked manner. A condition is considered X-linked if the genetic change that causes the condition is located on the X chromosome, one of the two sex chromosomes (the Y chromosome is the other sex chromosome). In males (who have only one X chromosome), a duplication of the MECP2 gene in each cell is sufficient to cause the condition. In females (who have two X chromosomes), a duplication of one of the two copies of the gene typically does not cause the disorder. Early in the development of females, one of the two X chromosomes is randomly and permanently inactivated in each cell (called X-inactivation). X-inactivation prevents female cells from having twice as many functional X chromosomes as males. Because X-inactivation is usually random, the X chromosome inherited from the mother is active in some cells, and the X chromosome inherited from the father is active in other cells. However, when a female has an X chromosome with a duplicated copy of the MECP2 gene, the abnormal chromosome is often preferentially inactivated in many or all cells. This is called "skewed X-inactivation." It prevents some women with an MECP2 duplication from developing features of the duplication since the extra genetic material is not active. In most cases, MECP2 duplication syndrome is inherited from a mother who has no signs or symptoms of the duplication. Rarely, the condition is not inherited and occurs due to a random event during the formation of the egg or sperm, or in early fetal development. When this happens, it is called a de novo duplication (occurring as a new genetic change for the first time in the affected person). |
exams and tests | How to diagnose MECP2 duplication syndrome ? | How is MECP2 duplication syndrome diagnosed? A diagnosis of MECP2 duplication syndrome is often suspected based on the presence of characteristic signs and symptoms. Genetic testing can then be ordered to confirm the diagnosis. |
treatment | What are the treatments for MECP2 duplication syndrome ? | How might MECP2 duplication syndrome be treated? Because MECP2 duplication syndrome affects many different systems of the body, medical management is often provided by a team of doctors and other healthcare professionals. Treatment for this condition varies based on the signs and symptoms present in each person. For example, infants with trouble swallowing and/or other feeding difficulties may require a feeding tube. Early developmental interventions may be recommended to help affected children reach their potential. This may include physical therapy, speech therapy and/or occupational therapy. Medications may be prescribed to treat seizures or spasticity. Recurrent infections are usually treated aggressively with appropriate antibiotics. Please speak with a healthcare provider if you have any questions about your personal medical management plan or that of a family member. |

causes | What causes Mosaic trisomy 14 ? | What causes mosaic trisomy 14? Individuals with mosaic trisomy 14 have a duplication of chromosome 14 material in some of their cells, while other cells have a normal chromosomal makeup. The additional chromosomal material is responsible for the features that are characteristic of the condition. Most cases of mosaic trisomy 14 appear to result from random errors in the separation of chromosomes (nondisjunction) -- either during the division of the egg or sperm in one of the parents, or during cell division after fertilization. There have been some reports in which it may have occurred due to other phenomenon, such as uniparental disomy or the formation of an isochromosome. Uniparental disomy is when an affected individual inherits both copies of a chromosomal pair from one parent, rather than one copy from each parent. An isochromosome is an abnormal chromosome with identical arms on each side of the centromere. Unique has a leaflet on their Web site that contains additional descriptions and illustrations of how mosaic trisomy 14 may occur. Click here to view the leaflet. |
treatment | What are the treatments for Mosaic trisomy 14 ? | How might mosaic trisomy 14 be treated? Treatment for signs and symptoms of mosaic trisomy 14 focuses on the specific features present in each individual. Infants with congenital heart defects may need surgery or other therapies to alleviate symptoms and correct heart malformations. Respiratory infections should be treated aggressively and early. Some infants and children with the condition may need surgical repair of certain craniofacial, genital, or other abnormalities. Early intervention may be important in ensuring that children with the reach their potential. Special services that may be beneficial include special education, physical therapy, and/or other medical, social, and/or vocational services. |

information | What is (are) Mulibrey Nanism ? | Mulibrey nanism is a rare genetic disorder characterized by profound growth delays and distinctive abnormalities of the muscles, liver, brain, and eyes. The acronym MULIBREY stands for (MU)scle, (LI)ver, (BR)ain, and (EY)e; nanism is another word for dwarfism. Signs and symptoms of the disorder may include constrictive pericarditis; low birth weight; short stature; severe progressive growth delays; hypotonia; hepatomegaly; and yellow discoloration of the eyes in infancy. It is caused by mutations in the TRIM37 gene and is inherited in an autosomal recessive manner. Treatment may include surgery for constrictive pericarditis, medications for progressive heart failure and hormone replacement therapy. |
symptoms | What are the symptoms of Mulibrey Nanism ? | What are the signs and symptoms of Mulibrey Nanism? Mulibrey nanism (MN) is characterized by progressive growth failure that begins prenatally (before birth). Hypotonia (poor muscle tone) is common. Newborns often have characteristic abnormalities of the head and face, including a triangularly shaped face. Yellow discoloration of the eyes and other ocular abnormalities may be present, but vision is usually normal. More than 90 percent of affected individuals have a J-shaped sella turcica, which is a depression in the sphenoid bone at the base of the skull. Infants with mulibrey nanism may also have symptoms related to overgrowth of the fibrous sac surrounding the heart (constrictive pericarditis). When constrictive pericarditis is present at birth, affected infants may have a bluish discoloration of the skin (cyanosis), especially on the lips and fingertips. Individuals with MN typically have a high-pitched voice. Other symptoms may include abnormally prominent veins in the neck, congestion in the lungs, abnormal fluid accumulation in the abdomen (ascites), swelling of the arms and/or legs (peripheral edema), and/or enlargement of the heart (cardiac hypertrophy) and/or liver (hepatomegaly). There may also be elevated pressure in the veins, congestion or blockage in the main artery serving the lungs (pulmonary artery), and/or a build-up of fibrous tissue in the walls of the lungs (pulmonary fibrosis). Associated complications of these conditions may lead to congestive heart failure. In some cases, individuals with mulibrey nanism may have additional physical abnormalities, such as an unusually thin shinbone (fibrous tibia dysplasia). Large cerebral ventricles in the brain and delayed motor development are uncommon findings. Most affected individuals have normal intelligence. Individuals with mulibrey nanism often have underdevelopment of various endocrine glands, that leads to hormone deficiencies. Delayed puberty sometimes occurs, accompanied by infrequent or very light menstrual periods. Females have an increased risk for premature ovarian failure and ovarian tumors. The Human Phenotype Ontology provides the following list of signs and symptoms for Mulibrey Nanism.

information | What is (are) Spondylocostal dysostosis 4 ? | Spondylocostal dysostosis is a group of conditions characterized by abnormal development of the bones in the spine and ribs. In the spine, the vertebrae are misshapen and fused. Many people with this condition have an abnormal side-to-side curvature of the spine (scoliosis). The ribs may be fused together or missing. These bone malformations lead to short, rigid necks and short midsections. Infants with spondylocostal dysostosis have small, narrow chests that cannot fully expand. This can lead to life-threatening breathing problems. Males with this condition are at an increased risk for inguinal hernia, where the diaphragm is pushed down, causing the abdomen to bulge out. There are several types of spondylocostal dysostosis. These types have similar features and are distinguished by their genetic cause and how they are inherited. Spondylocostal dysostosis 4 is caused by mutations in the HES7 gene. It is inherited in an autosomal recessive manner. Treatment is symptomatic and supportive and may include respiratory support and surgery to correct inguinal hernia and scoliosis. |

information | What is (are) Juvenile Huntington disease ? | Juvenile Huntington disease (HD) is a less common, early-onset form of Huntington disease that begins in childhood or adolescence. It is also a progressive disorder that causes the breakdown of brain cells in certain areas of the brain. This results in uncontrolled movements, loss of intellectual abilities, and emotional disturbances. Juvenile HD is defined by the onset of symptoms before age 20 years and accounts for 5-10% of HD cases. It is inherited in an autosomal dominant pattern and is caused by a mutation called a trinucleotide repeat in the HTT gene. Most often, children with juvenile HD inherit the mutation repeat from their fathers, although on occasion they inherit it from their mothers. Juvenile Huntington disease has a rapid disease progression once symptoms present. There currently is no cure. Treatment is supportive and focused on increasing quality of life. |
symptoms | What are the symptoms of Juvenile Huntington disease ? | What are the signs and symptoms of Juvenile Huntington disease? A common sign of juvenile HD is a rapid decline in school performance. Symptoms can also include subtle changes in handwriting and slight problems with movement, such as slowness, rigidity, tremor, and rapid muscular twitching, called myoclonus. Several of these symptoms are similar to those seen in Parkinson's disease, and they differ from the chorea seen in individuals who develop the disease as adults. People with juvenile HD may also have seizures and mental disabilities. The earlier the onset, the faster the disease seems to progress. The disease progresses most rapidly in individuals with juvenile or early-onset HD, and death often follows within 10 years. The Human Phenotype Ontology provides the following list of signs and symptoms for Juvenile Huntington disease. If the information is available, the table below includes how often the symptom is seen in people with this condition.

causes | What causes Juvenile Huntington disease ? | What causes Juvenile Huntington disease (HD)? Mutations in the HTT gene cause Huntington disease. The HTT gene provides instructions for making a protein called huntingtin. Although the function of this protein is unknown, it appears to play an important role in nerve cells (neurons) in the brain. When the huntingtin protein is abnormally made, it is thought to lead to the death of neurons in certain areas of the brain, which causes the signs and symptoms of Juvenile HD. The HTT mutation that causes Huntington disease involves a DNA segment known as a CAG trinucleotide repeat. This segment is made up of a series of three DNA building blocks (cytosine, adenine, and guanine) that appear multiple times in a row. Normally, the CAG segment is repeated 10 to 35 times within the gene. In people with juvenile HD, the CAG segment is repeated more than 60 times. |
inheritance | Is Juvenile Huntington disease inherited ? | How is Juvenile Huntington disease (HD) inherited? Juvenile HD is inherited in an autosomal dominant manner, which means that one copy of the altered gene in each cell is sufficient to cause the disorder. An affected person usually inherits the altered gene from one affected parent. As the altered HTT gene is passed from one generation to the next, the size of the CAG trinucleotide repeat often increases in size. A larger number of repeats is usually associated with an earlier onset of signs and symptoms (anticipation). A larger number of repeats is usually associated with an earlier onset of signs and symptoms. Most often, children with juvenile HD inherit the expanded CAG trinucleotide repeat from their fathers, although on occasion they inherit it from their mothers. |
exams and tests | How to diagnose Juvenile Huntington disease ? | How is Juvenile Huntington disease (HD) diagnosed? The diagnosis is usually made by experienced neurologists. A neurologist will often first obtain the persons medical history asking about recent intellectual or emotional problems, which may be indications of HD. A family history may be taken as well, looking for autosomal dominant inheritance in a family. Usually a clinical exam is also performed where the persons hearing, eye movements, strength, coordination, involuntary movements (chorea), sensation, reflexes, balance, movement, and mental status are examined. People with HD commonly have impairments in the way the eye follows or fixes on a moving target. Abnormalities of eye movements vary from person to person and differ, depending on the stage and duration of the illness. Genetic testing is usually done to confirm a diagnosis of juvenile HD in an individual who is exhibiting HD-like symptoms. Using a blood sample, the genetic test analyzes DNA for the HD mutation by counting the number of repeats in the HD gene region. GeneTests lists the names of laboratories that are performing genetic testing for Juvenile HD. To view the contact information for the clinical laboratories, conducting testing click here. Please note: Most of the laboratories listed through GeneTests do not accept direct contact from patients and their families; therefore, if you are interested in learning more, you will need to work with a health care provider or a genetics professional. In the Genetic Services section of this letter we provide a list of online resources that can assist you in locating a genetics professional near you. |
treatment | What are the treatments for Juvenile Huntington disease ? | How might Juvenile Huntington disease (HD) be treated? Physicians may prescribe a number of medications to help control emotional and movement problems associated with HD. It is important to remember however, that while medicines may help keep these clinical symptoms under control, there is no treatment to stop or reverse the course of the disease. Anticonvulsant drugs are usually prescribed to help prevent and control the seizures that occur in children with Juvenile HD. Tetrabenazine is often used to treat chorea. Antipsychotic drugs, such as haloperidol, or other drugs, such as clonazepam, may also help to alleviate chorea and may also be used to help control hallucinations, delusions, and violent outbursts. For depression, physicians may prescribe fluoxetine, sertraline, nortriptyline, or other drugs. Tranquilizers can help control anxiety and lithium may be prescribed to combat severe mood swings. |

information | What is (are) Singleton Merten syndrome ? | Singleton Merten syndrome is an extremely rare, multisystem disorder. The major characteristics are tooth abnormalities (dental dysplasia); calcifications in the aorta and certain valves of the heart (i.e., aortic and mitral valves); and progressive thinning and loss of protein of the bones (osteoporosis), especially the upper and back portions of the skull. Other physical findings may include generalized muscle weakness; progressive muscle atrophy; growth delay; delays in motor development; skin conditions; and/or malformation of the hips and/or feet. It appears to occur sporadically (in individuals with no history of the condition in their family) but in some cases, autosomal dominant inheritance has been suggested. Treatment is typically directed toward the specific symptoms that are present in each individual. |
symptoms | What are the symptoms of Singleton Merten syndrome ? | What are the signs and symptoms of Singleton Merten syndrome? Singleton Merten syndrome is characterized by abnormalities of the teeth (dental dysplasia); abnormal accumulation of calcium deposits (calcifications) in the aorta and certain valves of the heart (i.e., aortic and mitral valves); and/or progressive thinning and loss of protein of the bones (osteoporosis). Between the ages of four to 24 months, most affected infants experience generalized muscle weakness and loss or wasting away (atrophy) of muscle tissue. In approximately half of the reported cases, these symptoms begin after an episode of illness associated with a fever. Affected infants may also show delays in general physical development, possibly resulting in short stature or delays in the ability to coordinate muscles and perform certain tasks (motor development). Abnormalities affecting the teeth also occur at an early age in individuals with Singleton Merten syndrome. Affected infants may develop cavities and lose their primary teeth prematurely. Certain permanent teeth may not develop or may erupt late; those permanent teeth that do develop are usually malformed. In some cases, permanent teeth may also be lost prematurely. By late infancy or early childhood, affected individuals may experience symptoms associated with the progressive accumulation of calcium deposits (calcifications) in the aorta and on certain valves of the heart. The aorta arises from the lower pumping chamber of the heart (left ventricle) and supplies oxygen-rich blood to all the arteries of the body (excluding the pulmonary artery). In individuals with Singleton Merten Syndrome, calcifications form in the portion of the aorta nearest the heart (proximal thoracic aorta). The accumulation of calcium deposits is progressive and typically causes blockage and narrowing of the aorta (called calcific aortic stenosis), obstructing the flow of oxygenated blood. In some cases, abnormal calcium deposits may also develop around the valve on the left side of the heart (mitral valve calcification). As a result of calcification of these various structures, affected individuals may experience high blood pressure (hypertension); abnormal transmission of electrical impulses (conduction) that coordinate the activity of the heart muscle (heart block); abnormal contractions of the heart (systolic murmurs); and/or abnormal enlargement of the heart (cardiomegaly). By late adolescence, the heart may be unable to pump blood effectively, causing heart failure and leading to life-threatening complications. Infants with Singleton Merten syndrome may also experience abnormal thinning and weakness of the bones (osteoporosis). As a result, bones are frequently brittle and may fracture easily. Osteoporosis may occur in the skull and the long bones of the arms and legs, but is most prominent in the bones of the hands and fingers. Other findings associated with Singleton Merten syndrome may include malformations of the hips and feet that may occur due to muscle weakness; wearing away (erosion) of the bones in the tips of the fingers (terminal phalanges); and/or a chronic skin condition characterized by red, thick, scaly patches of skin (psoriasiform skin eruption). In some cases, affected individuals may have abnormal accumulation of pressure of the fluid of the eye (glaucoma) and/or abnormal sensitivity to light (photosensitivity). The Human Phenotype Ontology provides the following list of signs and symptoms for Singleton Merten syndrome. If the information is available, the table below includes how often the symptom is seen in people with this condition.

In these cases, the sign or symptom may be rare or common. |
exams and tests | How to diagnose Singleton Merten syndrome ? | How is Singleton Merten syndrome diagnosed? The diagnosis of Singleton Merten syndrome may be suspected during infancy based upon the identification of characteristic physical findings (i.e., muscle weakness, muscle atrophy, dental abnormalities, and skeletal changes). A diagnosis may be confirmed by a thorough clinical evaluation, a detailed patient history, and/or a variety of specialized tests. The identification of calcium deposits in the aorta, in association with the other findings described above, strongly suggests a diagnosis of Singleton Merten syndrome. X-ray tests may be used to confirm the presence and extent of calcifications in the aorta. Obstruction or narrowing (stenosis) of the heart valves, particularly the aortic and mitral valves, may be confirmed by cardiac catheterization. During this procedure, a small hollow tube (catheter) is inserted into a large vein and threaded through the blood vessels leading to the heart. This procedure allows physicians to determine the rate of blood flow through the heart and measure the pressure within the heart. X-ray studies may also be performed to confirm the presence and extent of osteoporosis. Osteoporosis may be suspected when bone fractures occur more frequently than usual. X-ray tests may also reveal abnormal widening of the hollow parts of the bones that contain soft fatty tissue (bone marrow cavities) within the bones of the hands and/or feet. |
treatment | What are the treatments for Singleton Merten syndrome ? | How might Singleton Merten syndrome be treated? The treatment of Singleton Merten syndrome is directed toward the specific symptoms that are apparent in each individual. Treatment may require the coordinated efforts of a team of specialists. Pediatricians, surgeons, specialists who diagnose and treat abnormalities of the heart (cardiologists), dental specialists, physical therapists, specialists who diagnose and treat conditions of the skin (dermatologists), and other health care professionals may need to systematically and comprehensively plan an affected child's treatment. Specific therapies for the treatment of Singleton Merten syndrome are symptomatic and supportive. Special services that may be beneficial to affected children may include special social support, physical therapy, and other medical, social, and/or vocational services. Genetic counseling would be of benefit for affected individuals and their families. |
information | What is (are) Familial hyperinsulinism ? | Familial hyperinsulinism is an inherited condition that causes individuals to have abnormally high levels of insulin, which leads to frequent episodes of low blood sugar (hypoglycemia). In infants and young children, these episodes are characterized by a lack of energy (lethargy), irritability, and/or difficulty feeding. Repeated episodes of low blood sugar increase the risk for serious complications such as seizures, intellectual disability, breathing difficulties, and/or coma. Unlike typical episodes of hypoglycemia, which occur after periods without food (fasting), episodes of hypoglycemia in people with familial hyperinsulinism can also occur after eating or exercising. Mutations in at least seven genes have been found to cause this condition. It is often inherited in an autosomal recessive pattern or less commonly, an autosomal dominant pattern. |

information | What is (are) Loin pain hematuria syndrome ? | Loin pain hematuria syndrome (LPHS) is a condition that is characterized by persistent or recurrent loin pain and hematuria (blood in the urine). Other signs and symptoms include nausea and vomiting; a low-grade fever (up to 101F); and/or dysuria during episodes of pain. The exact underlying cause of LPHS is currently unknown; however, scientists suspect that it may be due to abnormalities of the glomerular basement membranes (the tissues in the kidney that filter blood); bleeding disorders; or crystal and/or stone formation in the kidneys. Treatment is symptomatic and usually consists of pain management. |
symptoms | What are the symptoms of Loin pain hematuria syndrome ? | What are the signs and symptoms of loin pain hematuria syndrome? As the name of the condition suggests, loin pain hematuria syndrome (LPHS) is characterized primarily by recurrent or persistent loin pain and/or hematuria (blood in the urine). The loin pain is sometimes described as burning or throbbing and may worsen with exercise or when lying in a supine (face upward) position. Although some may only experience pain on one side initially, most people with LPHS will eventually develop bilateral (on both sides) loin pain. During episodes of pain, affected people may also experience nausea and vomiting; a low-grade fever (up to 101F); and/or dysuria. |
causes | What causes Loin pain hematuria syndrome ? | What causes loin pain hematuria syndrome? The exact underlying cause of loin pain hematuria syndrome (LPHS) is currently unknown. However, scientists have proposed several theories. For example, some cases of LPHS may be due to abnormal glomerular basement membranes, which are the tissues in the kidney that filter blood. If these tissues are abnormal, red blood cells may be allowed to enter the urinary space, leading to both loin pain and hematuria (blood in the urine). Other factors that may lead to the signs and symptoms of LPHS include: Blood disorders, called coagulopathies, which impair the bloods ability to clot Spasms in the kidney's blood vessels which may restrict blood flow to certain tissues and lead to tissue death Up to 50% of people affected by LPHS also experience kidney stones. Some scientists, therefore, suspect that the formation of crystals and/or stones in the kidney may also contribute to the condition as they may block or injure the renal tubules (the long narrow tubes in the kidney that concentrate and transport urine). |
exams and tests | How to diagnose Loin pain hematuria syndrome ? | How is loin pain hematuria syndrome diagnosed? A diagnosis of loin pain hematuria syndrome is suspected based on the presence of characteristic signs and symptoms, after other conditions that cause similar features have been excluded. Severe hematuria (blood in urine) may be obvious; however, a urinalysis can be performed to detect microscopic levels of hematuria. In some cases, a kidney biopsy may also be recommended to evaluate the structure and function of the kidney. |
treatment | What are the treatments for Loin pain hematuria syndrome ? | How might loin pain hematuria syndrome be treated? Treatment of loin pain hematuria syndrome (LPHS) typically consists of pain management. Narcotics or oral opioids may be prescribed to help control pain. Patients with severe pain may need high-dose opioids daily and may occasionally require hospitalization for intravenous pain relievers and control of nausea. Limited evidence suggests that drugs that inhibit angiotensin may reduce the frequency and severity of episodes of loin pain and severe hematuria. People with debilitating pain who do not respond to other therapies may be offered surgery (i.e. a nerve block, nephrectomy, kidney auto-transplantation); however, surgical treatment of LPHS is controversial as studies suggest that it has limited value for treating recurrent pain. |
