rs4244285 is a SNP in the CYP2C19 gene, potentially encoding the CYP2C19*2 variant. This variant is the most common reason for poor metabolism of compounds like mephenytoin (an anti-convulsant), some antidepressants, the anti-platelet drug Plavix, and some drugs used for ulcer conditions of various types.
