TABLE 4.

Minor allele frequency of CYP2C9 *3, *2 and promoter pVNTR alleles

The LD r² refers to the pVNTR-S and *3, determined in different cohorts. The LD r² between *2 and pVNTR-S is zero in all cohorts. The SMX cohort was used in another study in which patients were taking SMX as described under Materials and Methods.
