information | What is (are) Nonbullous congenital ichthyosiform erythroderma ? | Nonbullous congenital ichthyosiform erythroderma (NBCIE) is a specific type of ichthyosis mainly affecting the skin. Most infants with NBCIE are born with a tight, shiny covering on their skin, called a collodion membrane, which is typically shed within a few weeks. Other signs and symptoms include redness of the skin (erythroderma); fine, white scales on the skin; and thickening of the skin on the palms and soles of feet (palmoplantar keratoderma). Some people with NBCIE also have outward turning eyelids (ectropion); outward turning lips (eclabium); and nails that do not grow normally (nail dystrophy). NBCIE may be caused by mutations in any one of at least three genes: ALOX12B, ALOXE3 or NIPAL4. In some people with NBCIE, the cause of the disorder is unknown. |

treatment | What are the treatments for Nonbullous congenital ichthyosiform erythroderma ? | How might nonbullous congenital ichthyosiform erythroderma be treated? There is currently no cure for nonbullous congenital ichthyosiform erythroderma (NBCIE). Treatment generally focuses on managing the specific signs and symptoms each individual has. For newborns, the most important goals are to provide a moist environment in an isolette, and to prevent and treat infections. Petrolatum-based creams and ointments are typically used to keep the skin soft and hydrated. As children age, keratolytic agents (agents that help the skin loosen and shed) such as alpha-hydroxy acid or urea preparations can be used to promote the peeling and thinning of the outer layer of the skin. For individuals with severe skin involvement, oral retinoid therapy may be recommended. However, because this is known to cause abnormalities in a developing fetus, it should be used with caution in women of child-bearing age. In general, any agents that irritate the skin should be avoided. Ectropion (turning out of the eyelid) can cause dryness of the cornea (especially at night), so artificial tears or prescription ointments may be used to keep the cornea moist. ClinicalTrials.gov provides access to information on clinical studies (including therapies) for different types of ichthyosis. To view a list of the studies currently listed, click here. |

information | What is (are) Cowden syndrome ? | Cowden syndrome is an inherited condition that is characterized primarily by multiple, noncancerous growths (called hamartomas) on various parts of the body. It is considered part of the PTEN Hamartoma Tumor Syndrome spectrum which also includes Bannayan-Riley-Ruvalcaba syndrome and Proteus syndrome. People affected by Cowden syndrome are also at an increased risk of developing certain types of cancer, such as breast, thyroid and endometrial (lining of the uterus) cancer. Most cases are caused by changes (mutations) in the PTEN gene and are inherited in an autosomal dominant manner. Management typically includes high-risk screening for associated tumors and/or prophylactic surgeries. |
symptoms | What are the symptoms of Cowden syndrome ? | What are the signs and symptoms of Cowden syndrome? Cowden syndrome is characterized primarily by multiple, noncancerous growths (called hamartomas) on various parts of the body. Approximately 99% of people affected by Cowden syndrome will have benign growths on the skin and/or in the mouth by the third decade of life. A majority of affected people will also develop growths (called hamartomatous polyps) along the inner lining of the gastrointestinal tract. People affected by Cowden syndrome also have an increased risk of developing certain types of cancer. Breast, thyroid and endometrial (the lining of the uterus) cancers are among the most commonly reported tumors. Other associated cancers include colorectal cancer, kidney cancer and melanoma. People with Cowden syndrome often develop cancers at earlier ages (before age 50) than people without a hereditary predisposition to cancer. Other signs and symptoms of Cowden syndrome may include benign diseases of the breast, thyroid, and endometrium; a rare, noncancerous brain tumor called Lhermitte-Duclos disease; an enlarged head (macrocephaly); autism spectrum disorder; intellectual disability; and vascular (the body's network of blood vessels) abnormalities.

causes | What causes Cowden syndrome ? | What causes Cowden syndrome? Most cases of Cowden syndrome are caused by changes (mutations) in the PTEN gene. PTEN is a tumor suppressor gene which means that it encodes a protein that helps keep cells from growing and dividing too rapidly or in an uncontrolled way. Mutations in PTEN result in a defective protein that is unable to carry out its normal role. This leads to the development of the various tumors and cancers associated with Cowden syndrome. Rarely, Cowden syndrome is caused by mutations in KLLN, SDHB, SDHC, SDHD, PIK3CA or AKT1. Some affected families have no identifiable mutation in any of the genes associated with Cowden syndrome; in these families, the exact underlying cause is unknown. |
inheritance | Is Cowden syndrome inherited ? | How is Cowden syndrome inherited? Cowden syndrome is inherited in an autosomal dominant manner. This means that to be affected, a person only needs a change (mutation) in one copy of the responsible gene in each cell. In some cases, an affected person inherits the mutation from an affected parent. Other cases may result from new (de novo) mutations in the gene. These cases occur in people with no history of the disorder in their family. A person with Cowden syndrome has a 50% chance with each pregnancy of passing along the altered gene to his or her child. |
exams and tests | How to diagnose Cowden syndrome ? | How is Cowden syndrome diagnosed? A diagnosis of Cowden syndrome is based on the presence of characteristic signs and symptoms. Genetic testing for a change (mutation) in the PTEN gene can then be ordered to confirm the diagnosis. If a mutation in PTEN is not identified, genetic testing for the other genes known to cause Cowden syndrome can be considered. GeneReviews offers more detailed information regarding the diagnosis of Cowden syndrome including the clinical diagnostic criteria. Click here to view this resource. The PTEN Cleveland Clinic Risk Calculator can be used to estimate the chance of finding a PTEN mutation in children and adults with signs and symptoms of Cowden syndrome. Is genetic testing available for Cowden syndrome? Yes, genetic testing is available for many of the genes known to cause Cowden syndrome. Carrier testing for at-risk relatives and prenatal testing are possible if the disease-causing mutation in the family is known. The Genetic Testing Registry (GTR) is a centralized online resource for information about genetic tests. The intended audience for the GTR is health care providers and researchers. Patients and consumers with specific questions about a genetic test should contact a health care provider or a genetics professional. |
treatment | What are the treatments for Cowden syndrome ? | How might Cowden syndrome be treated? Because Cowden syndrome is associated with an increased risk for certain types of cancer, management is typically focused on high-risk cancer screening. According to the National Comprehensive Cancer Network 2014, the recommended screening protocol for Cowden syndrome includes: Cancer Screening for Women Breast self exams beginning at age 18 Clinical breast exams every 6-12 months beginning at age 25** Annual mammogram and breast MRI beginning at age 30-35** Annual screening for endometrial cancer with ultrasound and/or random biopsy may be considered beginning at age 30-35 Prophylactic surgeries may be considered as a preventative option for some forms of cancer Cancer Screening for Men and Women Annual physical examination beginning at age 18** Annual thyroid ultrasound beginning at age 18** Baseline colonoscopy at age 35 with follow-up every 5 years (more frequent if polyps identified) Consider renal (kidney) ultrasound every 1-2 years beginning at age 40 **or individualized based on the earliest diagnosis of cancer in the family GeneReviews offers more specific information on the treatment and management of Cowden syndrome.

exams and tests | How to diagnose Roberts syndrome ? | How is Roberts syndrome diagnosed? The diagnosis of Roberts syndrome is suspected in individuals with the following: Prenatal growth delay ranging from mild to severe. Average birth length and weight is typically below the third percentile in most affected infants. Limb malformations including bilateral, symmetric tetraphocomelia (phocomelia of all 4 limbs) or hypomelia (underdevelopment of the limbs) caused by mesomelic shortening (shortening of the middle part of the limb). Upper limbs are typically more severely affected than lower limbs. Other limb malformations include oligodactyly with thumb aplasia (lack of formation) or hypoplasia (underdevelopment), syndactyly, clinodactyly, and elbow and knee flexion contractures (inability to fully straighten the arms and legs). Craniofacial abnormalities including bilateral cleft lip and/or palate, micrognathia (small jaw), hypertelorism (widely-spaced eyes), exophthalmos (bulging eyes), downslanting palpebral fissures, malar hypoplasia (underdeveloped cheek bones), hypoplastic nasal alae, and ear malformations. The diagnosis of Roberts syndrome relies on a cytogenetic blood test of individuals with the above features. Cytogenetic testing would show the characteristic chromosomal abnormalities that are present in individuals with the condition. Is genetic testing available for Roberts syndrome? Genetic testing is currently available for Roberts syndrome. GeneTests lists the names of laboratories that are performing genetic testing for Roberts syndrome.

information | What is (are) Hereditary lymphedema type II ? | Hereditary lymphedema type II is a primary lymphedema that results from abnormal transport of lymph fluid. Individuals with this condition usually develop swelling in the lower legs and feet during puberty. Some affected individuals develop a non-contagious skin infection called cellulitis, which can further damage the lymphatic vessels (the thin tubes that carry lymph fluid). While the cause of hereditary lymphedema type II is unknown, it is thought to be genetic because it tends to run in families. It appears to have an autosomal dominant pattern of inheritance. |
symptoms | What are the symptoms of Hereditary lymphedema type II ? | What are the signs and symptoms of Hereditary lymphedema type II? Hereditary lymphedema type II is characterized by the abnormal transport of lymph fluid. This causes the lymph fluid to build up, causing swelling (lymphedema). Individuals with hereditary lymphedema type II usually develop swelling in the lower legs and feet during puberty.

causes | What causes Hereditary lymphedema type II ? | What causes hereditary lymphedema type II? The cause of hereditary lymphedema type II is unknown. The condition is thought to be genetic because it tends to run in families. Researchers have studied many genes associated with the lymphatic system; however, to date, no specific genetic change has been associated with this type of lymphedema. |
inheritance | Is Hereditary lymphedema type II inherited ? | How is hereditary lymphedema type II inherited? Hereditary lymphedema type II appears to have an autosomal dominant pattern of inheritance, which means that one copy of an altered gene in each cell is sufficient to cause the disorder. People with hereditary lymphedema type II usually have at least one other affected family member, in most cases, a parent. When the condition occurs in only one person in a family, the condition is described as Meige-like lymphedema. |
information | What is (are) Aicardi-Goutieres syndrome type 5 ? | Aicardi-Goutieres syndrome is an inherited condition that mainly affects the brain, immune system, and skin. It is characterized by early-onset severe brain dysfunction (encephalopathy) that usually results in severe intellectual and physical disability. Additional symptoms may include epilepsy, painful, itchy skin lesion (chilblains), vision problems, and joint stiffness. Symptoms usually progress over several months before the disease course stabilizes. There are six different types of Aicardi-Goutieres syndrome, which are distinguished by the gene that causes the condition: TREX1, RNASEH2A, RNASEH2B, RNASEH2C, SAMHD1, and ADAR genes. Most cases are inherited in an autosomal recessive pattern, although rare autosomal dominant cases have been reported. Treatment is symptomatic and supportive. |

inheritance | Is Usher syndrome, type 2C inherited ? | How is Usher syndrome inherited? Usher syndrome is inherited in an autosomal recessive manner. This means that a person must have a change (mutation) in both copies of the disease-causing gene in each cell to have Usher syndrome. One mutated copy is typically inherited from each parent, who are each referred to as a carrier. Carriers of an autosomal recessive condition usually do not have any signs or symptoms. When two carriers of an autosomal recessive condition have children, each child has a 25% (1 in 4) chance to have the condition, a 50% (1 in 2) chance to be an unaffected carrier like each parent, and a 25% chance to not be a carrier and not be affected. |
information | What is (are) Primary angiitis of the central nervous system ? | Primary angiitis of the central nervous system is a rare form of vasculitis (inflammation of blood vessels) affecting the blood vessels that nourish the brain, spinal cord and peripheral nerves. This condition can lead to narrowing and blockage of the blood vessels of the central nervous system which can eventually cause aneurysms, ischemia and/or hemmorrhage. The cause of this condition is unknown. Signs and symptoms of this condition may begin suddenly or develop over time. Some of the symptoms may incude headaches that do not go away, fever, rapid weight loss, confusion or forgetfulness, and general malaise. Treatment for this condition involves a course of immunosuppresive steroids. |
treatment | What are the treatments for Primary angiitis of the central nervous system ? | How might primary angiitis of the central nervous system be treated? The current treatment recommendation is to start with oral prednisone at a dose of 1 mg/kg per day and cyclophosphamide at a dose of 2 mg/kg per day. Most centers use prednisone and cyclophosphamide for 4-6 months to induce clinical remission, and then taper prednisone off. Patients generally stay on cyclophosphamide therapy between three and six months, depending on when remission occurs and if there are any potential side effects from cyclophosphamide. Once cyclophosphamide is discontinued, it should be replaced with a less toxic medication for an additional six to twelve months of maintenance therapy. Some doctors switch from cyclophosphamide to azathioprine (2 mg/kg) or mycophenolate mofetil. Methotrexate can also be used, but may be limited by its difficulty to cross the blood brain barrier. There is limited data on how long the maintenance therapy lasts so the decision on the duration of the therapy should be individualized, based upon how the patient responds to therapy. |

information | What is (are) Subacute cerebellar degeneration ? | Subacute cerebellar degeneration is the breakdown of the area of the brain that controls muscle coordination and balance (the cerebellum). Less commonly, the area connecting the spinal cord to the brain is involved. Subacute cerebellar degeneration may occur in association with a cancer (paraneoplastic cerebellar degeneration) or lack of thiamine (alcoholic or nutritional cerebellar degeneration). Signs and symptoms may include ataxia, speech and swallowing problems, dementia, vision problems, and vertigo. |
symptoms | What are the symptoms of Subacute cerebellar degeneration ? | What are the signs and symptoms of subacute cerebellar degeneration? Signs and symptoms of subacute cerebellar degeneration, include ataxia, speech and swallowing problems, dementia (in about half of people with this condition), and difficulty walking. People with subacute cerebellar degeneration due to thiamine deficiency may also experience quick involuntary movements of the eyeball (nystagmus), double-vision, dizziness, and paralysis of the eye muscles. In paraneoplastic cerebellar degeneration, dizziness, nausea, and vomiting may precede the neurological symptoms. Paraneoplastic cerebellar degeneration may occur in association with Lambert Eaton myasthenic syndrome or encephalomyelitis. |
causes | What causes Subacute cerebellar degeneration ? | What causes subacute cerebellar degeneration? Subacute cerebellar degeneration may occur when the body's immune system attacks healthy tissue, either for unknown reasons or as an abnormal reaction to an underlying cancer. These cases are referred to as paraneoplastic cerebellar degeneration. Subacute cerebellar degeneration may also occur due to thiamine deficiency. Causes of thiamin deficiency include alcoholism, recurrent vomiting, gastric surgery, and diets poor in this B vitamin. These cases are referred to as alcoholic/nutritional cerebellar degeneration. For further information pertaining to the neurological effects of severe thiamine deficiency, see the following link to the Wernicke-Korsakoff syndrome resource page. http://rarediseases.info.nih.gov/gard/6843/wernicke-korsakoff-syndrome/Resources/1 |
information | What is (are) Tietz syndrome ? | Tietz syndrome is a rare condition that affects the development of melanocytes, the cells in our body that produce and contain melanin (the pigment that gives color to skin, hair, and eyes). Signs and symptoms of this condition are present from birth and usually include sensorineural hearing loss, fair skin, and light-colored hair. It is caused by changes (mutations) in the MITF gene and inherited in an autosomal dominant manner. The goal of treatment is to improve hearing; cochlear implantation may be considered. |

exams and tests | How to diagnose Tietz syndrome ? | How is Tietz syndrome diagnosed? A diagnosis of Tietz syndrome is suspected in people with severe, bilateral (both ears) sensorineural hearing loss; fair skin; and light-colored hair. Identification of a change (mutation) in the MITF gene also supports this diagnosis. Diagnosing Tietz syndrome can be complicated since there are several different genetic conditions that can cause deafness and hypopigmentation, some of which are also caused by mutations in the MITF gene. It is, therefore, important for people with suspected Tietz syndrome to be evaluated by a healthcare provider who specializes in genetics. |

information | What is (are) Twin twin transfusion syndrome ? | Twin-to-twin transfusion syndrome is a rare condition that occurs when blood moves from one identical twin (the donor twin) to the other (the recipient twin) while in the womb. The donor twin may be born smaller, with paleness, anemia, and dehydration. The recipient twin may be born larger, with redness, too much blood, and increased blood pressure, resulting in an increased risk for heart failure. Treatment may require repeated amniocentesis during pregnancy. Fetal laser surgery may be done to interrupt the flow of blood from one twin to the other. After birth, treatment depends on the infant's specific symptoms. The donor twin may need a blood transfusion to treat anemia. The recipient twin may need to have the volume of body fluid reduced. This may involve an exchange transfusion. Medications may be given to treat heart failure in the recipient twin. |
information | What is (are) Acute intermittent porphyria ? | Acute intermittent porphyria (AIP) is one of the liver (hepatic) porphyrias. AIP is caused by low levels of porphobilinogen deaminase (PBGD), an enzyme also often called hydroxymethylbilane synthase. The low levels of PBGD are generally not sufficient to cause symptoms; however, activating factors such as hormones, drugs, and dietary changes may trigger symptoms. Although most individuals with AIP never develop symptoms, symptomatic individuals typically present with abdominal pain with nausea. Treatment is dependent on the symptoms. |
symptoms | What are the symptoms of Acute intermittent porphyria ? | What are the signs and symptoms of Acute intermittent porphyria? Some people who inherit the gene for AIP never develop symptoms and are said to have "latent" AIP. Those individuals that present with symptoms usually do so after puberty, probably because of hormonal influences, although other activating factors include: alcohol, drugs (e.g., barbiturates, steroids, sulfa-containing antibiotics), chemicals, smoking, reduced caloric intake, stress, and travel. Symptoms usually last several days, but attacks for which treatment is not received promptly may last weeks or months. Abdominal pain, which is associated with nausea and can be severe, is the most common symptom and usually the first sign of an attack. Other symptoms may include : Gastrointestinal issues (e.g., nausea, vomiting, constipation, diarrhea, abdominal distention, ileus) Urinary tract issues (e.g., urinary retention, urinary incontinence, or dysuria) Neurological issues (e.g., muscle weakness in the arms or legs, paralysis) Psychiatric issues (e.g., insomnia, hysteria, anxiety, apathy or depression, phobias, psychosis, agitation, delirium, somnolence, or coma) Individuals with AIP have an increased risk of developing hepatocellular carcinoma; some develop kidney failure. The Human Phenotype Ontology provides the following list of signs and symptoms for Acute intermittent porphyria.

causes | What causes Acute intermittent porphyria ? | What causes acute intermittent porphyria (AIP)? AIP is caused by the deficiency of an enzyme called porphobilinogen deaminase (PBGD), also known as hydroxymethylbilane synthase (HMBS) and formerly known as uroporphyrinogen I-synthase. The deficiency of PBGD is caused by a mutation in the HMBS gene. The HMBS gene is the only gene known to be associated with AIP. However, the deficiency of PBGD alone is not enough to cause AIP. Other activating factors (e.g., hormones, drugs, dietary changes) must also be present. |
inheritance | Is Acute intermittent porphyria inherited ? | How is acute intermittent porphyria (AIP) inherited? AIP is inherited in an autosomal dominant fashion, which means only one of the two HMBS genes needs to have a disease-causing mutation to decrease enzyme activity and cause symptoms. |
exams and tests | How to diagnose Acute intermittent porphyria ? | How is acute intermittent porphyria (AIP) diagnosed? Diagnosis of AIP is suspected in individuals with otherwise unexplained severe, acute abdominal pain without physical signs. The finding of increased levels of delta-aminolevulinic acid (ALA) and porphobilinogen (PBG) in urine establishes that one of the acute porphyrias is present. If PBGD is deficient in normal red blod cells, the diagnosis of AIP is established. The diagnosis is confirmed in individuals with a disease-causing mutation in the HMBS gene, the only gene known to be associated with AIP, which encodes the erythrocyte hydroxymethylbilane synthase enzyme. Molecular genetic testing of the HMBS gene detects more than 98% of affected individuals and is available in clinical laboratories. To obtain a list of clinical laboratories offering genetic testing for AIP, click here. |
treatment | What are the treatments for Acute intermittent porphyria ? | How might acute intermittent porphyria (AIP) be treated? Treatment of AIP may vary based on the trigger of the attack and the symptoms present. Treatment may include stopping medications that cause or worsen the symptoms, treating any infections which may be present, administration of pain medication, monitoring fluid balance and/or correcting electrolyte disturbances, monitoring neurologic status and administering respiratory support. Mild attacks can be manged with increased caloric intake and fluid replacement. Recurrent acute attacks should be managed by a porphyria specialist. Hospitalization is often necessary. Panhematin, an intravenous medication used to correct heme deficiency, may also be prescribed. More detailed information about the use of Panhematin for the treatment of AIP can be found by clicking here. |

information | What is (are) SHORT syndrome ? | SHORT syndrome is a condition characterized by multiple abnormalities that affect several parts of the body. The term SHORT is an acronym with each letter representing a common feature in affected individuals: (S) short stature; (H) hyperextensibility of joints and/or hernia (inguinal); (O) ocular depression (deep-set eyes); (R) Rieger anomaly (defective development of the anterior chamber of the eye that can lead to glaucoma); and (T) teething delay. Other features commonly present include a triangular face, small chin with a dimple, loss of fat under the skin (lipodystrophy), abnormal position of the ears, hearing loss and delayed speech. It is caused by mutations in the PIK3R1 gene. Inheritance is autosomal dominant. Treatment focuses on the specific symptoms present in each individual. |
symptoms | What are the symptoms of SHORT syndrome ? | What are the signs and symptoms of SHORT syndrome? SHORT syndrome is a disorder that affects multiple parts of the body. It is mainly characterized by several features that are represented by the acronym SHORT: (S) short stature; (H) hyperextensible joints (joints that stretch more than usual) and/or hernia (inguinal); (O) ocular depression (deep-set eyes); (R) Rieger anomaly (defective development of the anterior chamber of the eye that can lead to glaucoma); and (T) teething delay. A loss of fat under the skin (lipodystrophy), usually most prominent in the face and upper body, is also a main feature of the syndrome. Affected individuals often have additional, distinctive, facial features including a small chin with a dimple; triangular-shaped face; prominent forehead; abnormal positioning of the ears; large ears; underdeveloped (hypoplastic) or thin nostrils; and thin, wrinkled skin that gives the impression of premature aging. Intelligence is often normal, but some affected individuals have speech delay and/or other developmental delays in childhood. Hearing loss is common. Affected infants may have difficulty gaining weight and may be prone to illnesses. Individuals may also develop diabetes in the second decade of life. The Human Phenotype Ontology provides the following list of signs and symptoms for SHORT syndrome.

inheritance | Is SHORT syndrome inherited ? | How is SHORT syndrome inherited? SHORT syndrome is inherited in an autosomal dominant pattern. For conditions with autosomal dominant inheritance, one abnormal copy of the causative gene in each cell is sufficient to cause signs and symptoms of the condition. The abnormal copy of the gene may be inherited from an affected parent, or it may occur for the first time in an affected individual. When an individual with an autosomal dominant condition has children, each child has a 50% (1 in 2) risk to be affected. |
exams and tests | How to diagnose SHORT syndrome ? | How is SHORT syndrome diagnosed? There is no formal criteria for diagnosis yet. The term SHORT syndrome was first created to reflect several of the features of the original reported cases: Short stature, Hyperextensibility, Ocular depression (deeply set eyes), Rieger anomaly, and Teething delay. However, it is now recognized that all of these five features are neither required to make the diagnosis nor necessarily the most specific features of SHORT syndrome. The features most consistently observed in SHORT syndrome include: Intrauterine growth restriction (IUGR) Short stature Partial lipodystrophy Facial characteristics: Face with triangular shape, prominent forehead, deep-set eyes, nose with a narrow low-hanging tip and thin nasal alae, small chin with a central dimple and large ears that are low-set. Other frequent features include: Axenfeld-Rieger anomaly or related eye anomalies Delayed dentition Diabetes. In general, the facial features allow to make a suspicion of the diagnosis. Diagnosis is confirmed with the genetic testing showing a mutation in the PIK3R1 gene. |

causes | What causes Marden-Walker syndrome ? | What causes Marden-Walker syndrome? The underlying cause of Marden-Walker syndrome has not been clearly established. It appears to be a developmental disorder of the central nervous system and is likely to be the expression of various heterogeneous diseases. |
inheritance | Is Marden-Walker syndrome inherited ? | Is Marden-Walker syndrome inherited? Marden-Walker syndrome is thought to be inherited in an autosomal recessive manner since cases of affected siblings and parental consanguinity (the parents of the child with the condition are related to each other) have been reported. |
treatment | What are the treatments for Marden-Walker syndrome ? | How might Marden-Walker syndrome be treated? Very little information is available regarding the treatment of Marden-Walker syndrome. In general, treatment is symptomatic, with a multidisciplinary approach. The team of providers may include a regular pediatrician, a geneticist, a neurologist, an orthopedist and/or a physical medicine specialist. Special diets and feeding techniques may be of benefit. Early childhood intervention services may help with developmental problems. Other treatments are dependent upon the specific symptoms present in each patient. |
information | What is (are) Cone dystrophy ? | Cone dystrophy is a general term for a group of rare eye disorders that affect the cone cells of the retina. Cone cells allow a person to see color and fine detail, and they work best in bright light. The cone dystrophies can cause a variety of symptoms such as decreased visual clarity when looking straight ahead, a reduced ability to see colors, and an increased sensitivity to light. There are two main subtypes of cone dystrophy, called stationary cone dystrophy and progressive cone dystrophy. The age when symptoms begin, the type and severity of symptoms, and the progression of symptoms are all very different between individuals, even between people with the same type of cone dystrophy. Mutations in many genes have been found to cause cone dystrophy, and the condition can be inherited in an autosomal dominant, autosomal recessive, or x-linked manner. |
symptoms | What are the symptoms of Cone dystrophy ? | What are the signs and symptoms of Cone dystrophy?

In these cases, the sign or symptom may be rare or common. |
exams and tests | How to diagnose Cone dystrophy ? | How is cone dystrophy diagnosed? The diagnosis of cone dystrophy is made based upon the presence of characteristic symptoms, a detailed family history, a thorough clinical evaluation and a number of supporting tests. While exams that measure visual acuity, perception of color, and field of vision are used to arrive at a proper diagnosis, an electroretinogram (ERG) is used to confirm the diagnosis. During an ERG, eye drops are used to numb the eye before a special contact lens recorder is placed on the eye. Then a series of flashes of light are used to stimulate the retina. Doctors can then measure the electrical response of the rods and cones to the light. The test is performed twice once in bright room and again in a dark room. A weak of absent signal of cone cells indicates cone dystrophy. More details about the diagnosis of cone dystrophy can be accessed through the University of Michigan Kellogg Eye Center. |
information | What is (are) Lysinuric protein intolerance ? | Lysinuric protein intolerance is a metabolic disorder caused by the body's inability to digest and use the amino acids lysine, arginine, and ornithine. Because the body cannot effectively break down these amino acids, which are found in many protein-rich foods, individuals experience nausea and vomiting after ingesting protein. Other features associated with protein intolerance may also occur, including short stature, muscle weakness, impaired immune function, and osteoporosis. A lung disorder called pulmonary alveolar proteinosis may develop in some individuals, as can end-stage renal disease, coma and intellectual disability. Symptoms usually develop after infants are weaned and begin to eat solid foods. Lysinuric protein intolerance is caused by mutations in the SLC7A7 gene.

information | What is (are) Takayasu arteritis ? | Takayasu arteritis is a condition that causes inflammation of the main blood vessel that carries blood from the heart to the rest of the body (aorta) and its associated branched blood vessels. As a result of the inflammation, the blood vessel walls become thick and make it difficult for blood to flow. Over time, impaired blood flow causes damage to the heart and various other organs of the body. Although the cause remains unknown, Takayasu arteritis appears to be an autoimmune condition, in which cells that fight infection and disease are wrongly targeted against the body's own tissues. |

information | What is (are) Juvenile dermatomyositis ? | Juvenile dermatomyositis has some similarities to adult dermatomyositis and polymyositis. It typically affects children ages 2 to 15 years, with symptoms that include weakness of the muscles close to the trunk of the body, inflammation, edema, muscle pain, fatigue, skin rashes, abdominal pain, fever, and contractures. Children with juvenile dermatomyositis may have difficulty swallowing and breathing, and the heart may also be affected. About 20 to 30 percent of children with juvenile dermatomyositis develop calcium deposits in the soft tissue. Affected children may not show higher than normal levels of the muscle enzyme creatine kinase in their blood but have higher than normal levels of other muscle enzymes. |

information | What is (are) Urachal cancer ? | Urachal cancer is a rare type of bladder cancer, making up less than 1% of all bladder cancers. Only about 350 cases have been described in the medical literature to date. The urachus is a primitive structure which before birth connected the bellybutton and the bladder. This connection normally disappears before birth, but in some people remains. Urachal cancers are classified as such based on location at the dome or anterior wall of the bladder and discovery of remnants of the urachus. Most urachal cancers are adenocarcinomas (cancers that develop from gland cells). Others may be sarcomas (which develop from connective tissue - such as leiomyosarcoma, rhabdomyosarcoma, and malignant fibrous histiocytoma), small cell carcinomas, transitional cell cancer, and mixed neoplasias. Most individuals with urachal cancer present with hematuria (blood in urine). Other symptoms may include abdominal pain, a palpable abdominal mass, mucinuria, and bacteriuria. Patients who present with early disease confined to the urachus have a good prognosis when treated with partial cystectomy, umbilicotomy, and urachal resection. The prognosis for those with advanced disease is less promising. |
treatment | What are the treatments for Urachal cancer ? | How might urachal cancer be treated? Surgical resection in the form of partial (segmental) or radical cystoprostatectomy is the main form of treatment. However, similar results are seen with a conservative surgery that involves partial cystectomy with umbilicotomy and removal of the urachus. The role of chemotherapy and radiation therapy for the treatment of urachal cancer is unclear, although some studies show that chemotherapy can induce objective response in some cases. Chemotherapy regimens that may be used include: single-agent 5-fluorouracil (5-FU), 5-FU and cisplatin, 5-FU, lomustine and vincristine, taxol and cisplatin, platinum and etoposide, and MVAC (methotrexate, vinblastine, doxorubicin, cisplatin) alone or in conjunction with radiation therapy. |

information | What is (are) Papillary renal cell carcinoma ? | Papillary renal cell carcinoma (PRCC) is a type of cancer that occurs in the kidneys. It accounts for about 10-15% of all renal cell carcinomas.Renal cell carcinomas are a type of kidney cancer that develop in the lining of very small tubes (tubules) in the kidney.The term "papillary" describes the finger-like projections that can be found in most of the tumors. PRCC can be divided into two types: type 1, which is more common and usually grows more slowly and type 2, which are usually more aggressive .Though the exact cause of papillary renal cell carcinoma is unknown, smoking, obesity, and genetic predisposition conditions (such as hereditary leiomyomatosis and renal cell cancer) may contribute to the development of this type of cancer. Treatment often begins with surgery to remove as much of the cancer as possible, and may be followed by radiation therapy, chemotherapy, biological therapy, or targeted therapy. |

information | What is (are) Book syndrome ? | Book syndrome is a very rare type of ectodermal dysplasia. Signs and symptoms include premolar aplasia (when the premolars fail to develop); excessive sweating (hyperhidrosis); and premature graying of the hair. Other features that have been reported in only one person include a narrow palate (roof of the mouth); hypoplastic (underdeveloped) nails; eyebrow anomalies; a unilateral simian crease; and poorly formed dermatoglyphics (skin patterns on the hands and feet). Book syndrome is inherited in an autosomal dominant manner. |
symptoms | What are the symptoms of Book syndrome ? | What are the signs and symptoms of Book syndrome? To our knowledge, Book syndrome has only been reported in one, large Swedish family (25 cases in 4 generations) and in one other isolated case. The signs and symptoms reported in the Swedish family included premolar aplasia (when the premolars fail to develop); excessive sweating (hyperhidrosis); and early whitening of the hair. Early whitening of the hair was the most constant symptom, being found in every affected family member. The age of onset of this symptom ranged from age 6 to age 23. In some cases, there was whitening of hair on other parts of the body such as the armipits, genital hair, and eyebrows. Two-thirds of the affected people had an abnormality of the sweat glands. In the isolated case, additional features that were reported include a narrow palate (roof of the mouth); hypoplastic (underdeveloped) nails; eyebrow anomalies; a unilateral simian crease; and poorly formed dermatoglyphics (skin patterns on the hands and feet).

inheritance | Is Book syndrome inherited ? | How is Book syndrome inherited? To our knowledge, Book syndrome has only been reported in one, large Swedish family (25 cases in 4 generations) and in one other isolated case. In the Swedish family, the syndrome was inherited in an autosomal dominant manner. In autosomal dominant inheritance, having a mutation in only one copy of the responsible gene is enough to cause signs and symptoms of the condition. When a person with an autosomal dominant condition has children, each child has a 50% (1 in 2) risk to inherit the mutated copy of the gene. |
