Genetic variation at human ApoA1 gene. Using the Haploview 4.2 software and the HapMap phrase II database, we scanned 5 genotyped single-nucleotide polymorphisms (SNPs) in Chinese Han. Linkage disequilibrium (LD) blocks across the locus in Chinese Han. LD block derived by solid spline method in Haploview 4.2. LD value shown: (A) |D’| × 100; |D’| colour scheme: |D’| =0: white; 0 < |D’| < 1: shades of pink; |D’| =1: red; (B) r ² × 100; r ² colour scheme: r ² = 0: white; 0 < r 2 < 1: shades of grey; r ² = 1: black.
