Meta-Analysis Of Genome-Wide Association Studies Identifies Multiple Lung Cancer Susceptibility Loci In Never-Smoking Asian Women
HUMAN MOLECULAR GENETICS(2016)
摘要
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 (6877 cases and 6277 controls) using the 1000 Genomes Project (Phase 1 Release 3) data as the reference and genotyped additional samples (5878 cases and 7046 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 x 10(-13)), rs72658409 at 9p21.3 (per-allele OR = 0.77; P = 1.41 x 10(-10)) and rs11610143 at 12q13.13 (per-allele OR = 0.89; P = 4.96 x 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.
