SNPs analyzed in the A3F gene.
(A) Gene structure and SNP locations. The colored blocks indicate exons, empty blocks, untranslated regions (UTR), horizontal arrows, the direction of transcription and vertical arrows, the positions of SNPs. (B) Linkage disequilibrium matrix of SNPs in the A3F gene region in European Americans, as illustrated by Haploview . Red block indicates D’ = 1.0, and the number in the blocks indicates the value of D’. The linkage disequilibrium block depicted by black triangle was based on the 95% Confidence interval criteria. (C) Haplotypes in the A3F gene region in European Americans.
