Question:  What is (are) Bartter syndrome ?
Answer: Bartter syndrome is a group of similar kidney disorders that cause an imbalance of potassium, sodium, chloride, and other molecules in the body. In some cases, the condition manifests before birth with increased amniotic fluid surrounding the affected fetus (polyhydramnios). Affected infants typically do not grow and gain wait as expected. Dehydration, constipation and increased urine production result from losing too much salt (sodium chloride) in the urine, and weakening of the bones can occur due to excess loss of calcium. Low levels of potassium in the blood (hypokalemia) can cause muscle weakness, cramping, and fatigue. It is caused by mutations in any one of at least 5 genes and is inherited in an autosomal recessive manner. The different types of Bartter syndrome are classified according to the specific gene that causes the condition. Treatment depends on the type of the syndrome present but chiefly focuses on preventing the loss of too much potassium from the body.
Question:  What causes Bartter syndrome ?
Answer: What causes Bartter syndrome? Bartter syndrome may be caused by mutations in any one of several genes; the genetic cause in each case corresponds to the type of Bartter syndrome each affected individual has. Types I, II and IV typically result in the antenatal forms of Bartter syndrome (beginning before birth) while type III results in classical Bartter syndrome (usually beginning in early childhood). Type I results from mutations in the SLC12A1 gene; type II from mutations in the KCNJ1 gene; type III from mutations in the CLCNKB gene; and type IV from mutations in the BSND gene, or from a combination of mutations in the CLCNKA and CLCNKB genes. In some people with Bartter syndrome, the genetic cause of the disorder remains unknown; there may be other genes that cause the condition that have not yet been identified. All of these genes are essential for normal kidney function - they are involved in the kidneys' abilities to reabsorb salt. Abnormal changes in these genes impair these abilities, allowing for the loss of excess salt through the urine and also affecting the reabsorption of other things including potassium and calcium. The resulting imbalance of these in the body lead to the signs and symptoms of Bartter syndrome.
Question:  Is Bartter syndrome inherited ?
Answer: How is Bartter syndrome inherited? Bartter syndrome is inherited in an autosomal recessive manner, which means that both copies of the disease-causing gene (one inherited from each parent) have a mutation in an affected individual. Parents who each carry one mutated copy of the gene are referred to as carriers and typically do not have signs or symptoms of the condition. When two carriers for an autosomal recessive condition have children, each child has a 25% (1 in 4) risk to have the condition, a 50% (1 in 2) risk to be a carrier like each of the parents, and a 25% chance to not have the condition and not be a carrier.

Question:  How to diagnose Bartter syndrome ?
Answer: How is Bartter syndrome diagnosed? Bartter syndrome is usually diagnosed after a combination of tests are performed on an individual with the signs and symptoms of the condition. Blood test results in an affected individual typically show low blood potassium levels (with normal blood pressure); low blood chloride levels; and an acid/base balance that is skewed towards the base (i.e. the blood is more alkaline than usual). High levels of the hormones renin and aldosterone in the blood would also support the diagnosis. Urine test results that would support the diagnosis include high levels of potassium and chloride, suggesting that the kidneys have impaired ability to control the concentrations of these electrolytes. A positive genetic test result would confirm the diagnosis. Is genetic testing available for Bartter syndrome? Yes, genetic testing for Bartter syndrome is available.

Question:  What are the treatments for Bartter syndrome ?
Answer: How might Bartter syndrome be treated? Treatment of Bartter syndrome depends on the type of the syndrome that the affected individual has, but it primarily focuses on preventing the loss of too much of potassium from the body. This may include oral potassium (K) supplements, medication such as indomethacin, and potassium-sparing diuretics. In high-stress situations such as illness or trauma, blood electrolyte levels can change rapidly, which may require immediate intravenous treatment. Genetic counseling may benefit affected individuals and their families. eMedicine has an article containing additional, thorough information about the management and treatment of Bartter syndrome.

Question:  What is (are) Mevalonic aciduria ?
Answer: Mevalonic aciduria is the severe form of mevalonate kinase deficiency, a condition characterized by recurrent episodes of fever that typically begin during infancy. During these fever episodes, people with mevalonic aciduria may have an enlarged liver and spleen (hepatosplenomegaly), lymphadenopathy, abdominal pain, diarrhea, joint pain (arthralgia), and skin rashes. Additional ongoing issues include developmental delay, progressive ataxia, progressive problems with vision, an unusually small, elongated head, and failure to thrive. Mevalonic aciduria is caused by deficiency of mevalonate kinase, the first committed enzyme of cholesterol biosynthesis. This deficiency occurs as a result of inherited mutations in the MVK gene. This condition is inherited in an autosomal recessive pattern. Treatment is challenging and remains mainly supportive. The less severe type of mevalonate kinase deficiency is called hyperimmunoglobulinemia D syndrome (HIDS).
Question:  What are the symptoms of Mevalonic aciduria ?
Answer: What are the signs and symptoms of Mevalonic aciduria? The Human Phenotype Ontology provides the following list of signs and symptoms for Mevalonic aciduria. 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) Cerebral cortical atrophy 90% Cognitive impairment 90% Delayed skeletal maturation 90% Dolichocephaly 90% Microcephaly 90% Muscular hypotonia 90% Seizures 90% Short stature 90% Splenomegaly 90% Triangular face 90% Blue sclerae 50% Cataract 50% Incoordination 50% Low-set, posteriorly rotated ears 50% Kyphoscoliosis 5% Aciduria - Agenesis of cerebellar vermis - Arthralgia - Autosomal recessive inheritance - Cerebellar atrophy - Cerebral atrophy - Diarrhea - Edema - Elevated hepatic transaminases - Elevated serum creatine phosphokinase - Failure to thrive - Fluctuating hepatomegaly - Fluctuating splenomegaly - Large fontanelles - Leukocytosis - Low-set ears - Lymphadenopathy - Morbilliform rash - Normocytic hypoplastic anemia - Nystagmus - Posteriorly rotated ears - Progressive cerebellar ataxia - Skin rash - Thrombocytopenia - Vomiting - 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.
Question:  What are the treatments for Mevalonic aciduria ?
Answer: How might mevalonic aciduria be treated? Treatment of mevalonic aciduria remains a challenge. There is no standard treatment that is effective in all patients, so it remains mainly supportive. Treatment with simvastatin (an inhibitor of hydroxymethylglutaryl coenzyme A reductase, the enzyme that catalyzes the formation of mevalonic acid), which has been used with guarded success in patients with HIDS, worsened the clinical status of two patients with mevalonic aciduria. Anakinra, another medication used with some degree of success in HIDS patients, induced partial remission in at least one patient with mevalonic aciduria, but not all patients respond to so favorably.  Reports of successful treatment of mevalonic aciduria through allogenic bone marrow transplantation have also surfaced. At this point, this therapy is investigational and potentially applicable to patients with mevalonic aciduria whose condition is resistant to therapy with anti-inflammatory drugs (e.g., inhibitors of TNF-alpha and interleukin-1 beta). The following articles provide additional details regarding treatment of mevalonic aciduria.

Question:  What is (are) Retinochoroidal coloboma ?
Answer: Retinochoroidal coloboma is an eye abnormality that occurs before birth. It is characterized by missing pieces of tissue in both the retina (the light-sensitive tissue lining the back of the eye) and choroid (the blood vessel layer under the retina). In many cases, retinochoroidal coloboma does not cause symptoms. However, complications such as retinal detachment may occur at any age. Other possible complications include loss of visual clarity or distorted vision; cataract; and abnormal blood vessel growth in the choroid (choroidal neovascularization). Retinochoroidal coloboma can involve one or both eyes, and may occur alone or in association with other birth defects. It can be inherited or can occur sporadically.
Question:  What is (are) Gordon syndrome ?
Answer: Gordon Syndrome is a rare, inherited type of distal arthrogryposis typically characterized by a combination of camptodactyly (a permanent fixation of several fingers in a flexed position), clubfoot (abnormal bending inward of the foot), and less frequently, cleft palate. Intelligence is usually normal. In some cases, additional abnormalities such as scoliosis or undescended testicles in males may be present. The range and severity of symptoms may vary from case to case. Gordon syndrome is thought to be inherited in an autosomal dominant or X-linked dominant manner. The exact cause remains unknown.
Question:  Is Gordon syndrome inherited ?
Answer: How is Gordon syndrome inherited? While some reports suggest Gordon syndrome may be inherited in an X-linked dominant manner, most agree that it is inherited in an autosomal dominant manner with reduced expressivity and incomplete penetrance in females. In autosomal dominant inheritance, having only one mutated copy of the disease-causing gene in each 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) risk to inherit the mutated copy of the gene. If a condition shows variable or reduced expressivity, it means that there can be a range in the nature and severity of signs and symptoms among affected individuals. Incomplete penetrance means that a portion of the individuals who carry the mutated copy of the disease-causing gene will not have any features of the condition.
Question:  What is (are) Retinal vasculopathy with cerebral leukodystrophy ?
Answer: Retinal vasculopathy with cerebral leukodystrophy (RVCL) is a rare, genetic condition that primarily affects the central nervous system. Symptoms begin in adulthood (usually in the 40s) and may include loss of vision, mini-strokes, and dementia. Death can sometimes occur within 10 years of the first symptoms appearing. RVCL is inherited in an autosomal dominant manner and is caused by mutations in the TREX1 gene. Treatments currently aim to manage or alleviate the symptoms rather than treating the underlying cause. RVCL is now considered to include the following 3 conditions which were previously thought to be distinct: hereditary endotheliopathy, retinopathy, nephropathy, and stroke (HERNS); cerebroretinal vasculopathy (CRV); and hereditary vascular retinopathy (HVR).

Question:  What is (are) Vici syndrome ?
Answer: Vici syndrome is a multisystem disorder characterized by agenesis (failure to develop) of the corpus callosum, cataracts , hypopigmentation of the eyes and hair, cardiomyopathy, and combined immunodeficiency. Hearing loss, seizures, and delayed motor development have also been reported. Swallowing and feeding difficulties early on may result in a failure to thrive. Recurrent infections of the respiratory, gastrointestinal, and urinary tracts are common. Vici syndrome is caused by mutations in the EPG5 gene and is inherited in an autosomal recessive manner. Treatment is mainly supportive.
