ICD-11 5C52.11 — Bile acid synthesis defect with cholestasis
Anomalies of bile acid synthesis are a group of sterol metabolism disorders due to enzyme deficiencies of bile acid synthesis in infants, children and adults, with variable manifestations that include cholestasis, neurological disease, and fat malabsorption. Eight inborn errors have been clearly identified, 7 of which lead to liver cholestasis and include: 3-beta-hydroxy-C27-steroid oxidoreductase deficiency (type 1), delta4-3-oxosteriod-5-beta reductase deficiency (type 2), oxysterol 7alpha-hydroxylase deficiency (type 3), 2-methylacyl-CoA racemase deficiency (type 4), bile acid CoA ligase deficiency, and cerebrotendinous xanthomatosis. Cholesterol 7alpha-hydroxylase deficiency leads to hypercholesterolaemia without liver cholestasis.
