Genes affected

CYP2C19 (HGNC:2621): (cytochrome P450 family 2 subfamily C member 19) 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 protein localizes to the endoplasmic reticulum and is known to metabolize many xenobiotics, including the anticonvulsive drug mephenytoin, omeprazole, diazepam and some barbiturates. Polymorphism within this gene is associated with variable ability to metabolize mephenytoin, known as the poor metabolizer and extensive metabolizer phenotypes. The gene is located within a cluster of cytochrome P450 genes on chromosome 10q24. [provided by RefSeq, Jul 2008]

ACMG classification

Classification made for transcript

Verdict is Benign. Variant got -12 ACMG points.

BP4

This place is a probable branch point but rather VUS (scored 5 / 10). Computational evidence support a benign effect (BayesDel_noAF=-0.86).

BA1

GnomAd4 highest subpopulation (SAS) allele frequency at 95% confidence interval = 0.318 is higher than 0.05.
