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.

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 10, 2024The c.265G>A (p.G89R) alteration is located in exon 1 (coding exon 1) of the CH25H gene. This alteration results from a G to A substitution at nucleotide position 265, causing the glycine (G) at amino acid position 89 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
