Summaries for Homocystinuria

Genetics Home Reference : 25 Homocystinuria is an inherited disorder in which the body is unable to process certain building blocks of proteins (amino acids) properly. There are multiple forms of homocystinuria, which are distinguished by their signs and symptoms and genetic cause. The most common form of homocystinuria is characterized by nearsightedness (myopia), dislocation of the lens at the front of the eye, an increased risk of abnormal blood clotting, and brittle bones that are prone to fracture (osteoporosis) or other skeletal abnormalities. Some affected individuals also have developmental delay and learning problems. Less common forms of homocystinuria can cause intellectual disability, failure to grow and gain weight at the expected rate (failure to thrive), seizures, problems with movement, and a blood disorder called megaloblastic anemia. Megaloblastic anemia occurs when a person has a low number of red blood cells (anemia), and the remaining red blood cells are larger than normal (megaloblastic). The signs and symptoms of homocystinuria typically develop within the first year of life, although some mildly affected people may not develop features until later in childhood or adulthood.

MalaCards based summary : Homocystinuria, also known as cystathionine beta synthase deficiency, is related to methylmalonic acidemia with homocystinuria and homocystinuria due to deficiency of n -methylenetetrahydrofolate reductase activity, and has symptoms including seizures An important gene associated with Homocystinuria is CBS (Cystathionine Beta-Synthase), and among its related pathways/superpathways are Glycine, serine and threonine metabolism and Cysteine and methionine metabolism. The drugs Methylcobalamin and Enalapril have been mentioned in the context of this disorder. Affiliated tissues include eye, bone and testes.

Disease Ontology : 12 An amino acid metabolic disorder that involves an accumulation of homocysteine in the serum and an increased excretion of homocysteine in the urine.

NIH Rare Diseases : 53 Homocystinuria refers to a group of inherited disorders in which the body is unable to process certain building blocks of proteins (amino acids) properly. This leads to increased amounts of homocysteine and other amnio acids in the blood and urine. The most common type of genetic homocystinuria, called CBS deficiency, is caused by the lack of an enzyme known as cystathionine beta-synthase (CBS). Most states in the United States test for homocystinuria due to CBS deficiency at birth by newborn screening. Other types are less common, and are caused by different missing or non-working enzymes. Homocystinuria can affect the eyes, skeleton, central nervous system and the blood clotting system. Mutations in the MTHFR, MTR, MTRR and MMADHC genes can cause homocystinuria. All these forms of homocystinuria are inherited in an autosomal recessive manner. Treatment and long-term outlook varies depending upon the cause of the disorder.

KEGG : 37
Homocystinuria is a metabolic disorder due to cystathionine beta-synthase deficiency leading to various malfunctions in the eyes and the central nervous, skeletal, and vascular systems.
