Genes affected

CH25H (HGNC:1907): (cholesterol 25-hydroxylase) This is an intronless gene that is involved in cholesterol and lipid metabolism. The encoded protein is a membrane protein and contains clusters of histidine residues essential for catalytic activity. Unlike most other sterol hydroxylases, this enzyme is a member of a small family of enzymes that utilize diiron cofactors to catalyze the hydroxylation of hydrophobic substrates.

The c.212A>G (p.Y71C) alteration is located in exon 1 (coding exon 1) of the CH25H gene. This alteration results from a A to G substitution at nucleotide position 212, causing the tyrosine (Y) at amino acid position 71 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
