Homocystinuria, Cystathionine beta-Synthase Deficiency, also known as homocystinuria, is a inherited disorder of amino acid methionine metabolism caused by a defective cystathionine beta-Synthase. Cystathionine beta-Synthase catalyzes the conversion of homocysteine and L-Serine into L-Cystathionine which is the substrate of cystathionine gamma-lyase. This disorder is characterized by a large accumulation of homocysteine in the cell. Symptoms of the disorder include thromboembolism, ectopia lentis and/or severe myopia, skeletal system deficiency and developmental delay. Treatment with homocystinuria aims at correct the biochemical abnormalities through disorder management (e.g. surveillance, circumstances to avoid, prevention of primary manifestations, etc.
