CLL genotype data for R620W variant or surrogate rs6679677
Fisher exact test (carriers vs noncarriers) P = .033; Cochran-Armitage Trend Test P = .062. AA + AG vs GG genotype odds ratio = 2.15; 95% confidence interval, 1.07-4.29.
Fisher exact test (carriers vs noncarriers) P = .019; Cochran-Armitage Trend Test P = .041. AA + AC vs CC genotype odds ratio = 1.58; 95% confidence interval, 1.08-2.31.
The increased 620W frequency in GEC/PMRP controls over those in Negro et al reflects the well-described strong gradient from southern to northern/northeastern Europe.1
