Identification of Novel Loci and New Risk Variant in Known Loci for Colorectal Cancer Risk in East Asians.

ABSTRACT:

Background

Risk variants identified so far for colorectal cancer explain only a small proportion of familial risk of this cancer, particularly in Asians.

Methods

We performed a genome-wide association study (GWAS) of colorectal cancer in East Asians, including 23,572 colorectal cancer cases and 48,700 controls. To identify novel risk loci, we selected 60 promising risk variants for replication using data from 58,131 colorectal cancer cases and 67,347 controls of European descent. To identify additional risk variants in known colorectal cancer loci, we performed conditional analyses in East Asians.

Results

An indel variant, rs67052019 at 1p13.3, was found to be associated with colorectal cancer risk at P = 3.9 × 10^-8 in Asians (OR per allele de
