摘要: Much of the variation in inherited risk colorectal cancer (CRC) is probably due to combinations common low variants. We conducted a genome- wide association study 550,000 tag SNPs 930 familial tumor cases and 960 controls. The most strongly associated SNP (P = 1.72 x 10(-7), allelic test) was rs6983267 at 8q24.21. To validate this finding, we genotyped three additional CRC case-control series (4,361 affected individuals 3,752 controls; 1,901 1,079 1,072 415 controls) replicated association, providing P 1.27 10(-14) (allelic overall, with odds ratios (ORs) (95% confidence interval (c.i.): 1.16-1.39) 1.47 c.i.: 1.34-1.62) for heterozygotes rare homozygotes, respectively. Analyses based on 1,477 adenoma 2,136 controls suggest that susceptibility mediated through development adenomas (OR 1.21, 95% 1.10-1.34; 6.89 10(-5)). These data show common, low-penetrance alleles predispose neoplasia.
