Allele and genotype frequency of <i>CYP2C19</i> in a Tamilian population

Abstract

The distribution of CYP2C19*1/*1 in the Tamilian population is lower than that in Caucasians, Africans and the North Indian population. The CYP2C19*1/*2 is significantly higher in Tamilians when compared with other populations. The CYP2C19*1/*3 allele, which was not reported in the North Indian and Caucasian populations has been identified in 2.7% of the Tamilian population.
