Fig. 6From: Global genetic analyses reveal strong inter-ethnic variability in the loss of activity of the organic cation transporter OCT1World map of genetically determined loss of OCT1 activity. Frequencies of carriers of two (green), one (orange), and zero (red) completely active OCT1 alleles are shown for different regions around the world. The major alleles OCT1*1, *8, and *9 were regarded as completely activeBack to article page
