Chromosome 5p Region SNPs Are Associated with Risk of NSCLC among Women

Abstract

In a population-based case-control study, we explored the associations between 42 polymorphisms in seven genes in this region and non-small cell lung cancer (NSCLC) risk among Caucasian (364 cases; 380 controls) and African American (95 cases; 103 controls) women. TwoTERTregion SNPs, rs2075786 and rs2853677, conferred an increased risk of developing NSCLC, especially among African American women, andTERT-rs2735940 was associated with a decreased risk of lung cancer among African Americans. Five of the 20GHRpolymorphisms andSEPP1-rs6413428 were associated with a marginally increased risk of NSCLC among Caucasians. Random forest analysis reinforced the importance ofGHRamong Caucasians and identifiedAMACR, TERT, andGHRamong African Americans, which were also significant using gene-based risk scores. Smoking-SNP interactions were explored, and haplotypes inTERTandGHRassociated with NSCLC risk were identified. The roles ofTERT, GHR, AMACRandSEPP1genes in lung carcinogenesis warrant further exploration.
