" /> Glycerol kinase deficiency - CISMeF





Preferred Label : Glycerol kinase deficiency;

Symbol : GKD;

CISMeF acronym : GKD;

Type : Phenotype, molecular basis known;

Alternative titles and symbols : Gk deficiency; Gk1 deficiency; HYPERGLYCEROLEMIA;

Description : Francke et al. (1987) noted that there are 3 clinically distinct forms of glycerol kinase deficiency: infantile, juvenile, and adult. The infantile form is associated with severe developmental delay, and those with the adult form have no symptoms and are often detected fortuitously. The infantile form of GK deficiency, or the 'GK complex,' results from the Xp21 contiguous gene deletion syndrome (300679) with congenital adrenal hypoplasia (300200) and/or Duchenne muscular dystrophy (DMD; 310200), whereas the juvenile and adult forms have isolated GK deficiency (Walker et al., 1996).;

Inheritance : X-linked recessive;

Molecular basis : Caused by mutation in the glycerol kinase gene (GK, 300474);

Laboratory abnormalities : Increased urinary glycerol; Increased serum glycerol; Decreased glycerol kinase activity; Hypoglycemia; Pseudohypertriglyceridemia in adult form;

Prefixed ID : #307030;
