cerebrotendinous xanthomatosis
CTX
Cerebrotendinous xanthomatosis (CTX) is a familial sterol storage disease based on an inborn error of metabolism involving bile acid synthesis.
Predominant clinical features are a chronic progressive neurological syndrome, mental deterioration, bilateral cataract and xanthomas.
The presence of xanthomas usually leads to the diagnosis, and the reverse is probably also true: without xanthomas the diagnosis will often not be made. CTX may therefore be less rare than commonly thought, and the incidence of xanthomas in CTX may be overestimated.
