Shown in the table are GWAS from Iceland for variants that have been identified through GWAS results (published up to February 2009) and the original publication(s). Highly correlated markers are shown in parenthesis as well as the study reporting them. All P values are two-sided. Shown are the corresponding numbers of cases and controls (N), allelic frequencies of variants in affected and control individuals, the allelic odds-ratio (OR) with 95% confidence interval (95% CI) and P value adjusted for relatedness.
The original results published for the loci on 9q3315 and 22q1319 were from a study on cases with aggressive prostate cancer. Results for these two loci in Icelandic cases (N = 693) with more aggressive prostate cancer (Gleason score >6 and/or T3 or higher and/or node positive and/or metastatic disease), using the same set of controls, were not significant (rs1571801; ORaggr = 0.90 and P = 0.080, rs9623117; ORaggr = 1.00 and P = 0.94).
The SNP marker, rs4962416, at the 10q26 locus is not on the Illumina Hap300 chip, results shown for it are based on a weighted combination of two marker haplotype generated from rs7077275 and rs893856 that are present on the chip and tag the SNP (rs4962416).
