A cholesterol inhibitor, reducing the cholesterol concentration of bile. Chenodeoxycholic acid is one of the main bile acids produced by the liver.
CTX is a rare autosomal metabolic disorder due to mutation of the gene CYP27A1 encoding sterol 27-hydrolase. This enzyme is essential in turning cholesterol into bile acids and if not working properly, cholesterol and precursors of bile acids accumulate in various tissues resulting in xanthomatous swelling of tendons, early formation of cataract and progressive neurological symptoms, including dementia, seizures, hallucinations and depression . Prevalence 0.2 in 10,000 people in the EU .
