سیتوکروم P450 خانواده ۲ زیرخانواده C عضو ۹ (به اختصار CYP2C9) یک پروتئینآنزیمی است. این آنزیم در متابولیسم بیگانهزیستها، از جمله داروها و ترکیبات درونزا (مانند اسیدهای چرب) از طریق اکسایش نقش دارد. این پروتئین در انسان توسط ژنCYP2C9 کدگذاری می شود. این ژن بسیار چند ریخت است که بر بازدهی متابولیسم توسط آنزیم تأثیر می گذارد.

↑"CYP2C9". National Center for Biotechnology Information, U.S. National Library of Medicine. 29 March 2021. 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 its expression is induced by rifampin. The enzyme is known to metabolize many xenobiotics, including phenytoin, tolbutamide, ibuprofen and S-warfarin. Studies identifying individuals who are poor metabolizers of phenytoin and tolbutamide suggest that this gene is polymorphic. The gene is located within a cluster of cytochrome P450 genes on chromosome 10q24.
