Gene

CYP2C9

CYP2C9 makes a liver enzyme that processes several medicines. Its meaning is drug-specific: seven selected anti-inflammatory pain medicines use separate CPIC branches, phenytoin also requires HLA-B*15:02 and blood-level monitoring, and warfarin requires a multi-gene clinical algorithm. A complete result must cover ancestry-relevant alleles such as *5, *6, *8, and *11 rather than only *2 and *3.
