Cerebrotendinous xanthomatosis (CTX) is an autosomal-recessive disorder of lipid storage caused by mutations in the CYP27A1 gene, coding for a sterol 27-hydroxylase, leading to increased deposition of cholesterol in multiple tissues. CTX is characterized by the association of early non-neurological manifestations and adult-onset neurological dysfunctions (spastic ataxia, dementia, psychiatric disorders, peripheral neuropathy). Early and long-term treatment with chenodeoxycholic acid (CDCA) can slow down neurological symptoms progression, but diagnosis usually has a delay of several years. We report two Italian siblings having quite different phenotypes associated to a G-to-A transition in the c-1263 terminal causing a splicing alteration. This mutation has not been described before in Italy, and has been reported once in Japan. This case widens the clinical and genetic spectrum of Cerebrotendinous Xantomatosis in Italy and would like to suggest the importance of genetic testing in patients with autosomal recessive spastic paraparesis associated with typical non-neurological symptoms.

Abstract

Cerebrotendinous xanthomatosis (CTX) is an autosomal-recessive disorder of lipid storage caused by mutations in the CYP27A1 gene, coding for a sterol 27-hydroxylase, leading to increased deposition of cholesterol in multiple tissues. CTX is characterized by the association of early non-neurological manifestations and adult-onset neurological dysfunctions (spastic ataxia, dementia, psychiatric disorders, peripheral neuropathy). Early and long-term treatment with chenodeoxycholic acid (CDCA) can slow down neurological symptoms progression, but diagnosis usually has a delay of several years. We report two Italian siblings having quite different phenotypes associated to a G-to-A transition in the c-1263 terminal causing a splicing alteration. This mutation has not been described before in Italy, and has been reported once in Japan. This case widens the clinical and genetic spectrum of Cerebrotendinous Xantomatosis in Italy and would like to suggest the importance of genetic testing in patients with autosomal recessive spastic paraparesis associated with typical non-neurological symptoms.
