We investigated associations between the risk of lung cancer in residents of the coal-mining region and polymorphisms in the genes APEX1 (rs1130409), hOGG1 (rs1052133), XRCC1 (rs25489, rs25487), XRCC2 (rs3218536), XRCC3 (rs861539), ADPRT/PARP1 (rs1136410), XPD/ERCC2 (rs13181), XPG/ERCC5 (rs17655), XPC (rs2228001), ATM (rs1801516), and NBS1 (rs1805794).
To analyze the relationship of GSTT1, GSTM1, XRCC1 (rs25487), ERCC1 (rs11615, rs3212986), ERCC2 (rs13181), XRCC3 (rs861539), OGG1 (rs1052133), and Alpha-1-Antitrypsin mutations (AAT) with the risk of lung cancer in never-smokers, and ascertain if there is an effect modification between these polymorphisms and residential radon exposure.
In classification and regression tree analysis (CART), we observed a 6-fold risk for SCLC patients carrying XPA 5'UTR (M), XPD K751Q (W) (OR: 6.20; 95%CI: 2.40-16.01, p = 0.0001).Polymorphic NER genes might jointly modulate lung cancer risk through gene-gene and gene-smoking interaction.
As a result, 15 SNPs on or near 12 genes and one miRNA with strong evidence of association with lung cancer risk were identified, including TERT (rs2736098), CHRNA3 (rs1051730), AGPHD1 (rs8034191), CLPTM1L (rs401681 and rs402710), BAT3 (rs3117582), TRNAA (rs4324798), ERCC2 (Lys751Gln), miR-146a2 (rs2910164), CYP1B1 (Arg48Gly), GSTM1 (null/present), SOD2 (C47T), IL-10 (-592C/A and -819C/T), and TP53 (intron 6).

The analysis results showed that the following polymorphisms were correlated with susceptibility to lung cancer: rs4646903 in CYP1A1 (P < 0.001), rs1048943 in CYP1A1 (P < 0.001), rs1695 in GSTP1 (P < 0.05), rs13181 in ERCC2 (P < 0.001), and rs25487 in XRCC1 (P < 0.05); no such correlation existed in rs861539 in XRCC3 (P > 0.05).
In the present study, we investigated the polymorphisms of the following selected members of the base and nucleotide excision repair genes: XPC (Lys939Gln), XPD (Lys751Gln), XRCC1(Arg399Gln), and hOGG1(Ser326Ser), and the risk they present toward the development of lung cancer, with emphasis on the effect of chromium exposure.
This study aimed to explore the role of XRCC1 (Arg399Gln) and XPD (Lys751Gln) gene polymorphisms, lifestyle and environmental factors as well as their possible interactions in propensity to develop lung cancer in a population with high incidence from North East India.

This meta-analysis indicates that ERCC2 Lys751Gln polymorphism may lead to an increased susceptibility to lung c</span>ancer risk among Caucasians and Asians.
The haplotype ERCC2 rs3916874(G) and rs238415(C) [OR (95% CI)=1.26 (1.02-1.57), P=0.03] in block 1 and the haplotype PPP1R13L rs4803817(A), CD3EAP rs1046282(T), rs735482(C), ERCC1 rs3212980(A), rs3212964(G) [OR (95% CI)=3.56 (1.55-8.18), P=0.005] in block 3 were associated with lung cancer risk.

In conclusion, this meta-analysis suggested ERCC2 Asp312Asn polymorphism may increase the risk of lung cancer among Asians, whereas not among Caucasians.
In the present study, we investigated the polymorphisms of following selected DNA repair genes: XPC (Lys939Gln), XPD (Lys751Gln), hOGG1 (Ser326Cys) and XRCC1 (Arg399Gln), and the risks they present towards the development of lung cancer with the emphasis to gender differences within the Slovak population.
