Disease ID:1249
Associated with:1 target
acatalasia | catalase deficiency | Takahara disease
A rare autosomal recessive peroxisomal disorder caused by deficient activity of the enzyme, catalase, that was originally identified in patients suffering from ulcerating oral gangrene. different A number of CAT gene mutations that generate enzymes with varying degress of enzymatic deficiency have been identified. Heterozygotes have an intermediate level of catalase in the blood.

Orphanet: ORPHA926


Role:  Patients with acatalasemia are unable to breakdown hydrogen peroxide, leaving their tissues at risk of oxidative damage. Patients may be asymptomatic, but symptoms can include progressive oral gangrene. Acatalasemia is associated with diabetes mellitus and atherosclerosis in some defined populations.
Comments:  Genetic heterogeneity is found in patients with acatalasemia.
