Evaluation of cholesterol metabolism in cerebrotendinous xanthomatosis [PDF]

, 2015
Cerebrotendinous xanthomatosis (CTX) is a treatable bile acid disorder caused by mutations of CYP27A1. The pathogenesis of neurological damage has not been completely explained. Oral chenodeoxycholic acid (CDCA) can lead to clinical stabilization, but in

Cerebrotendinous xanthomatosis: reduced serum 26-hydroxycholesterol.

Journal of Lipid Research, 1982
Serum 26-hydroxycholesterol was quantitated by isotope dilution-mass spectrometry in normal individuals and in patients with cerebrotendinous xanthomatosis. In the normal individuals, the concentration of 26-hydroxycholesterol in serum ranged from 4.3 to

The Genetic Landscape of Hereditary Spastic Paraplegia in Greece

Clinical Genetics, Volume 109, Issue 5, Page 837-846, May 2026.
We investigated 112 Greek index‐cases with hereditary spastic paraplegia collected over > 25 years using NGS and MLPA. We identified a causative variant in 68 patients (60.7%), including 7 novel causative variants. This study presents a comprehensive overview of the phenotypic and genotypic spectrum of HSP in the Greek population.
