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.

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 21, 2022The c.649G>A (p.G217S) 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 649, causing the glycine (G) at amino acid position 217 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
