Genotype counts and frequencies of all markers in patients with primary gastric diffuse large B-cell lymphomas (high-grade gastric lymphoma) from the European multicenter study (EMCS) and healthy blood donors. Alleles are coded according to the plus strand (5′→3′ orientation of CDH1). Differences between n per category and sum of genotype scores per category and SNP are due to missing genotypes (call rate ≥ 95%). P values calculated for carriership of the rare allele. Pcorr. is the P value adjusted for multiple testing using Bonferroni’s correction (n=12). OR: odds ratio; 95% CI: 95% confidence interval. HWE: Hardy-Weinberg equilibrium (Pearson), CR: call rate.
