Risk of gastric cancer is associated with PRKAA1 gene polymorphisms in Koreans

Figure 1 Haplotype linkage disequilibrium blocks and haplotype frequencies for PRKAA1. A: Linkage disequilibrium blocks and correlation coefficients among PRKAA1 polymorphisms. Black squares indicate statistically significant allelic association between the pair of single nucleotide polymorphisms (SNPs), as measured by using the D statistic; darker gray indicate higher values of D, up to a maximum of 1; B: Haplotype frequencies of PRKAA1 polymorphisms in the case and control groups. Freq: Allele frequency.
