Pathway Description

27-Hydroxylase Deficiency

Homo sapiens
Disease Pathway
Created: 2014-06-23
Last Updated: 2025-01-24
Sterol 27-hydroxylase is a mitochondrial cytochrome P-450 species (CYP27) that catalyzes the first step in the degradation of steroid side chain in cholesterol to produce bile acids in the liver. When there are low concentrations of 27-Hydroxylase, patients will exhibit cerebrotendinous xanthomatosis, an autosomal recessive disorder characterized by the accumulation of cholestanol and cholesterol due to the inability to break down the lipids. The formation of xanthomas (deposits of lipids) in the nervous system and tendons will cause symptoms such as dementia, ataxia, and cataracts. Other symptoms may include damaged liver cells and body tissues.
