Mephenytoin 13-26 cytochrome P450 family 2 subfamily C member 18 Homo sapiens 56-63 8333835-2 1993 We have isolated genomic clones for CYP2C9 and CYP2C18 from the liver of an individual phenotyped in vitro as an extensive metabolizer of S-mephenytoin. Mephenytoin 138-151 cytochrome P450 family 2 subfamily C member 18 Homo sapiens 47-54 8333835-1 1993 There is a genetic polymorphism in humans in the metabolism of S-mephenytoin which has been suggested to be mediated by either CYP2C18 or CYP2C9. Mephenytoin 63-76 cytochrome P450 family 2 subfamily C member 18 Homo sapiens 127-134
