WebMar 9, 2024 · For example, the wild-type CYP2C9*1 allele has been assigned an activity score of 1, CYP2C9 alleles (e.g., CYP2C9*2) that cause a decrease in enzyme function are assigned an activity score of 0.5, and alleles (e.g., CYP2C9*3) with complete loss of enzyme activity have a score of 0. WebSignificant variations in CYP2C9 allele and genotype frequencies exist among different ancestry groups. Both CYP2C9 ∗ 2 and CYP2C9 ∗ 3 are more common in Caucasians (11% and 7%, respectively) than in Asians and Africans. In fact, CYP2C9 ∗ 2 has not been detected in Asians, in whom CYP2C9 ∗ 3 is the most common allele.
