N2 - Genome-wide association studies have been successful in elucidating the genetic basis of colorectal cancer, but there remains unexplained variability in genetic risk. To identify new risk variants and to confirm reported associations, we conducted a genome-wide association study in 1,701 colorectal cancer cases and 14,082 cancer-free controls from the Finnish population. A total of 9,068,015 genetic variants were imputed and tested, and 30 promising
variants were studied in additional 11,647 cases and 12,356 controls of European ancestry. The previously reported association between the single-nucleotide polymorphism rs992157 (2q35) and colorectal cancer was independently replicated (p=2.08x10-4; OR, 1.14; 95% CI, 1.06-1.23), and it was genome-wide significant in combined analysis (p=1.50x10-9; OR, 1.12;
95% CI, 1.08-1.16). Variants at 2q35, 6p21.2, 8q23.3, 8q24.21, 10q22.3, 10q24.2, 11q13.4, 11q23.1, 14q22.2, 15q13.3, 18q21.1, 20p12.3, and 20q13.33 were associated with colorectal cancer in the Finnish population (false discovery rate <0.1), but new risk loci were not found. These results replicate the effects of multiple loci on the risk of colorectal cancer and identify shared risk alleles between the Finnish population isolate and outbred populations.
