Acatalasemia, also known as acatalasia, is related to adrenoleukodystrophy and neonatal adrenoleukodystrophy. An important gene associated with Acatalasemia is CAT (Catalase), and among its related pathways/superpathways are Cellular responses to stimuli and Nuclear events mediated by NFE2L2. Affiliated tissues include liver and t cells, and related phenotypes are reduced catalase level and oral ulcer
