Acatalasia (also called acatalasemia, or Takahara's disease) 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.^{[citation needed]}

History

In 1948 , Dr.Shigeo Takahara (1908-1994), a Japanese otolaryngologist first reported this new disease.^{[citation needed]} 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.
