Rs1136410 Val762Ala Contributes to an Increased Risk of Overall Cancer in the East Asian Population: a Meta-analysis
Overview
Affiliations
Objectives: To investigate the association between poly(ADP-ribose) polymerase 1 () rs1136410 Val762Ala and cancer risk in Asian populations, as published findings remain controversial.
Methods: The PubMed and EMBASE databases were searched, and references of identified studies and reviews were screened, to find relevant studies. Meta-analyses were performed to evaluate the association between rs1136410 Val762Ala and cancer risk, reported as odds ratio (OR) and 95% confidence interval (CI).
Results: A total of 24 studies with 8 926 cases and 15 295 controls were included. Overall, a significant association was found between rs1136410 Val762Ala and cancer risk in East Asians (homozygous: OR 1.19, 95% CI 1.06, 1.35; heterozygous: OR 1.10, 95% CI 1.04, 1.17; recessive: OR 1.13, 95% CI 1.02, 1.25; dominant: OR 1.13, 95% CI 1.06, 1.19; and allele comparison: OR 1.09, 95% CI 1.03, 1.15). Stratification analyses by race and cancer type revealed similar results for gastric cancer among the Chinese population.
Conclusion: The findings suggest that rs1136410 Val762Ala may be significantly associated with an increased cancer risk in Asians, particularly the Chinese population.
