Preferred Label : Molybdenum cofactor deficiency, complementation group a;

Symbol : MOCODA;

CISMeF acronym : MOCODA;

Type : Phenotype, molecular basis known;

Alternative titles and symbols : Sulfite oxidase, xanthine dehydrogenase, and aldehyde oxidase, combined deficiency of;

Description : Molybdenum cofactor deficiency (MOCOD) is a rare autosomal recessive metabolic disorder characterized by onset in infancy of poor feeding, intractable seizures, and severe psychomotor retardation. Characteristic biochemical abnormalities include decreased serum uric acid and increased urine sulfite levels due to the combined enzymatic deficiency of xanthine dehydrogenase (XDH; 607633) and sulfite oxidase (SUOX; 606887), both of which use molybdenum as a cofactor. Most affected individuals die in early childhood (summary by Reiss, 2000; Reiss et al., 2011). - Genetic Heterogeneity of Molybdenum Cofactor Deficiency See also MOCOD, complementation group B (MOCODB; 252160), caused by mutation in the MOCS2 gene (602708) on chromosome 5q11; and MOCOD, complementation group C (MOCODC; 615501), caused by mutation in the GPHN gene (603930) on chromosome 14q24.;

Inheritance : Autosomal recessive;

Molecular basis : Caused by mutation in the molybdenum cofactor synthesis gene 1 (MOCS1, 603707.0001);

Laboratory abnormalities : Decreased xanthine dehydrogenase activity; Decreased sulfite oxidase activity; Hypouricemia; Molybdenum cofactor deficiency; Increased urinary hypoxanthine; Increased urinary taurine; Increased urinary S-sulfocysteine; Xanthine stones; Increased urinary xanthine;

Prefixed ID : #252150;
