Cerebrotendinous xanthomatosis (CTX) is a rare hereditary autosomal recessive disease caused by the mutations in the
CYP27A1 gene, that cause a sterol deficiency of the 27-hydroxylase enzyme involved in the synthesis of bile acids. The
deficiency leads to increased deposition of cholesterol and cholestanol in various tissues, while simultaneously makes
the structural and functional changes of cells and tissues. Patients experience clinical manifestations mostly in adulthood.
In addition to a wide range of neurological symptoms, signs of damage of other organ systems can be observed, some
of them in childhood. Neurological manifestations are caused by disorder in the central and the peripheral nervous
system. The epilepsy, parkinsonism, progressive ataxia, spastic paraparesis, and demyelinating polyneuropathy occur
in the clinical picture of a neurological nature.
