Clopidogrel requires activation by the CYP2C19 enzyme. Loss-of-function alleles can reduce active metabolite exposure 5 to 10-fold.

Clopidogrel requires activation by the CYP2C19 enzyme. Loss-of-function alleles can reduce active metabolite exposure 5 to 10-fold.

Clinical MH crises occur in roughly 1 in 10,000 pediatric and 1 in 50,000 adult anesthetics.

Irinotecan's active metabolite (SN-38) is inactivated by UGT1A1. Reduced-function alleles (*28, *6) slow this process, increasing SN-38 exposure and the risk of severe side effects.
