Table 2.

Frequency and relative activity of each of the common CYP2C9 genotypes

Genotype	Frequency (%)	Relative activity (%)
*1/*1	65.3	100
*1/*2	20.4	85
*1/*3	11.6	55
*2/*2	0.9	70
*2/*3	1.4	40
*3/*3	0.4	10

Frequencies are from Lee et al. [35]. Relative activities were based on the meta-analysis of the enzyme activities shown in Table 1, and assumptions regarding the heterogeneous genotypes (see Methods).
