General Discussion

Cerebrotendinous xanthomatosis (CTX) is a rare autosomal recessive genetic disorder caused by an abnormality in the CYP27A1 gene, resulting in a deficiency of the mitochondrial enzyme sterol 27-hydroxylase. The lack of this enzyme prevents cholesterol from being converted into a bile acid called chenodexoycholic acid. Cholestanol deposits accumulate in the nerve cells and membranes, and cause damage to the brain, spinal cord, tendons, lens of the eye and arteries. Affected individuals experience cataracts in childhood, and benign, fatty tumors (xanthomas) of the tendons during adolescence. This leads to progressive neurologic problems in adulthood such as paralysis, ataxia and dementia. Coronary heart disease is common.
