acatalasia

An autosomal dominant MIM 115500 condition of early onset first described in the Japanese, caused by a deficiency in tissue and RBC catalase, the enzyme that reduces H2O2; as H2O2 accumulates, malignant alveolar pyorrhea, and oral gangrene ensue, requiring removal of all teeth.
 
Molecular pathology
Acatalasia is caused by a mutation of CAT, located on chromosome 11p13, which encodes catalase, an anti-oxidant enzyme that converts hydrogen peroxide into water and oxygen.
