Fig. 3From: Meta-analysis of the global distribution of clinically relevant CYP2C8 alleles and their inferred functional consequencesThe frequencies of CYP2C8*2 and CYP2C8*3 are in anti-correlation. The association between national frequencies of CYP2C8*2 and CYP2C8*3 are shown for 22 countries. Note that allele frequency patterns cluster by geographical region and are in significant anti-correlation (r = 0.49; p = 0.0099)Back to article page
