Extreme xanthomatosis in patients with both familial hypercholesterolemia and cerebrotendinous xanthomatosis.

Multitendon xanthomatosis in a normo-cholesterolemic patient

We present a rare case of multisite xanthomatosis occurring in a 38-year-old normocholesterolemic man without a familial history. More commonly, these conditions are associated with familial hypercholesterolemia and cerebrotendinous xanthomatosis. Tendon xanthomas should prompt clinicians to perform a thorough investigation of the patient's metabolic panel and family history. Rarely, these cond...

Clinical and Genetic Characteristics of Splicing Variant in CYP27A1 in an Iranian Family with Cerebrotendinous xanthomatosis

Cerebrotendinous xanthomatosis (CTX) is a rare inborn lipid-storage disease leading to a progressive multisystem disease. CTX with autosomal recessive inheritance is caused by a defect in the CYP27A1 gene. Hallmark clinical manifestations of CTX include bilateral cataracts, chronic diarrhea, tendon xanthomas, and neurologic dysfunction. CTX is a rare disorder, which is supposed to be under-diag...

Cerebrotendinous xanthomatosis: a comprehensive review of pathogenesis, clinical manifestations, diagnosis, and management

Cerebrotendinous xanthomatosis (CTX) OMIM#213700 is a rare autosomal-recessive lipid storage disease caused by mutations in the CYP27A1 gene; this gene codes for the mitochondrial enzyme sterol 27-hydroxylase, which is involved in bile acid synthesis. The CYP27A1 gene is located on chromosome 2q33-qter and contains nine exons. A CYP27A1 mutation leads to decreased synthesis of bile acid, excess...

Sonographic Findings of Polyneuropathy Associated With Cerebrotendinous Xanthomatosis: A Case Report

Cerebrotendinous xanthomatosis is a rare autosomal recessive disease that involves multiple organs, including the peripheral nervous system. The present study is the first to report the ultrasonographic findings of peripheral nerves in a patient with cerebrotendinous xanthomatosis. The patient presented with bilateral Achilles tendon enlargement and foot hypesthesia. Sonographic examination rev...
