Genes affected

CYP2U1 (HGNC:20582): (cytochrome P450 family 2 subfamily U member 1) This gene encodes a member of the cytochrome P450 superfamily of enzymes. The cytochrome P450 proteins are monooxygenases which catalyze many reactions involved in drug metabolism and synthesis of cholesterol, steroids and other lipids. This enzyme is a hydroxylase that metabolizes arachidonic acid, docosahexaenoic acid, and other long chain fatty acids. [provided by RefSeq, Jul 2008]

CYP2U1-AS1 (HGNC:54817): (CYP2U1 and SGMS2 antisense RNA 1)

LOC107986298 (HGNC:):

ACMG classification

Our verdict: Benign. The variant received -12 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.71).
• BA1: GnomAd4 highest subpopulation (EAS) allele frequency at 95% confidence interval = 0.665 is higher than 0.05.
