Genome-wide association studies (GWAS) of lung cancer in Asian never-smoking women have previously identified six susceptibility loci associated with lung cancer risk. To further discover new susceptibility loci, we imputed data from four GWAS of Asian non-smoking female lung cancer (6,877 cases and 6,277 controls) using the 1,000 Genomes Project (Phase 1 Release 3) data as the reference and genotyped additional samples (5,878 cases and 7,046 controls) for possible replication. In our meta-analysis, three new loci achieved genome-wide significance, marked by single nucleotide polymorphism (SNP) rs7741164 at 6p21.1 (per-allele odds ratio (OR)=1.17; P=5.8×10(-13)), rs72658409 at 9p21.3 (per-allele OR=0.77; P=1.41 ×10(-10)), and rs11610143 at 12q13.13 (per-allele OR=0.89; P=4.96 ×10(-9)). These findings identified new genetic susceptibility alleles for lung cancer in never-smoking women in Asia and merit follow-up to understand their biological underpinnings.
