▶Association of 12 polymorphic variants conferring genetic risk to lung cancer in Indian population: An extensive meta‐analysisMeta-analysisN=19,556Debmalya Sengupta et al.(2017)· Environmental and Molecular Mutagenesis
A comprehensive meta-analysis of 50 case-control studies from the Indian subcontinent identified genetic variants modifying lung cancer risk, finding FDR-corrected associations for rs3547/XRCC1 (OR=1.83-2.72) and rs1048943/CYP1A1 (OR=2.07). The rs1048943/CYP1A1 variant showed strongest associations with adenocarcinoma (OR=3.38) and squamous cell carcinoma (OR=3.53) with significant effect modification by smoking status. Global meta-analysis confirmed rs1048943/CYP1A1 association across world populations (OR=1.22, p=0.01).
▶Variants in ABCB1 , TGFB1 , and XRCC1 genes and susceptibility to viral hepatitis A infection in Mexican AmericansAssociationN=6,779Lyna Zhang et al.(2012)· Hepatology
Candidate gene association study of 67 genetic variants in 27 inflammation and DNA repair genes with hepatitis A virus (HAV) infection susceptibility in 6,779 NHANES III participants (2,619 non-Hispanic whites, 2,095 non-Hispanic blacks, 2,065 Mexican Americans). Among Mexican Americans, ABCB1 rs1045642 T allele was associated with lower HAV seropositivity risk (OR=0.79, p<0.001), while TGFB1 rs1800469 and XRCC1 rs1799782 T alleles were associated with increased risk (OR=1.38 and 1.57, respectively). CAT rs769214 and CYP2E1 rs2031920 showed marginal associations with decreased and increased HAV risk, respectively.
About XRCC1
The protein encoded by this gene is involved in the efficient repair of DNA single-strand breaks formed by exposure to ionizing radiation and alkylating agents. This protein interacts with DNA ligase III, polymerase beta and poly (ADP-ribose) polymerase to participate in the base excision repair pathway. It may play a role in DNA processing during meiogenesis and recombination in germ cells. A rare microsatellite polymorphism in this gene is associated with cancer in patients of varying radiosensitivity. [provided by RefSeq, Jul 2008]
