Table 1. CYP2C9 allele (A) and genotype (B) frequencies in a large Korean sample. The expected genotype frequencies were calculated from the allele frequencies using the Hardy-Weinberg equation.

|---|---|---|---|
| Allele | n (3592) | Frequency | 95% CI |
| CYP2C9*1 | 3418 | 0.952 | 0.945–0.959 |
| CYP2C9*2 | 0 | 0.000 | 0.000–0.000 |
| CYP2C9*3 | 157 | 0.044 | 0.037–0.051 |
| CYP2C9*13 | 17 | 0.005 | 0.003–0.007 |

|---|---|---|---|---|
| Genotype | Number of subjects | Observed frequency | 95% CI | Expected frequency |
| CYP2C9*1/*1 | 1624 | 0.904 | 0.890–0.918 | 0.905 |
| CYP2C9*1/*3 | 153 | 0.085 | 0.072–0.098 | 0.083 |
| CYP2C9*1/*13 | 17 | 0.009 | 0.005–0.013 | 0.009 |
