Table 2.

Proportion of each dataset by ethnicity and minor allele frequency. Numbers in parentheses indicate the proportion of G allele carriers of a particular ethnicity group in a particular subsample. GG and GT genotype individuals were collapsed into one group for analysis due to low frequency of the G allele.
