Acatalasia (also called acatalasemia, or Takahara's disease[1]:809) is an autosomal recessive peroxisomal disorder caused by a complete lack of catalase.


The disorder is relatively benign, although it causes an increased incidence of periodontal infections, and can under rare circumstances lead to gangrene.[2]

Genetic Basis[edit]

Occurrence of acatalasia is often the result of mutation in the CAT gene which codes for the enzyme catalase.[3]


Researchers estimate that the condition occurs in every 12,500th person in Japan, every 20,000th in Hungary, and every 20,000th person in Switzerland.[3]


In 1948, Dr. Shigeo Takahara (1908–1994), a Japanese otolaryngologist first reported this new disease.[4] He had examined a patient with an oral ulcer. He had spread hydrogen peroxide on the diseased part, but oxygen was not generated due to the lack of catalase.
