Figure 1. Genotyping of rs2839471, rs577948, and rs11218544. The three SNPs were successfully genotyped in 2,870 subjects. M: 100 bp DNA ladder. A: RFLP analysis of SNP rs2839471. The double bands at 337 bp and 298 bp represent genotype C/T, the single band at 298 bp represents C/C, and the single band at 337 bp represents T/T. Capillary electrophoresis analysis was used for genotyping rs577948 and rs11218544. The three peak patterns represent three different SNP genotypes. B: SNP rs577948: the single peak at 181 bp is genotype A/A, the double peaks at 181 bp and 185 bp are A/G, and the single peak at 185 bp is G/G. C: SNP rs11218544: the single peak at 201 bp is T/T, the double peaks at 201 bp and 205 bp are T/G, and the single peak at 205 bp is G/G.
