Background: One of the most important DNA double-strand break (DSBs) repair genes is XRCC7 involved in non-homologous end joining (NHEJ). It is supposed that DNA repair gene malfunction is an important risk factor in various malignancies. The XRCC7 G6721T (rs7003908) polymorphism effect were investigated on the splicing regulation that cause mRNA instability.
Objective: The aim of present hospital-based study was to investigate the association between the G6721T common genetic polymorphism of XRCC7 and risk of acute lymphoblastic leukemia (ALL).
Methods: This case–control study was performed on 99 ALL patients versus 200 healthy blood donors (children), as the control group. Controls had no history of ALL, and they were frequent-matched by age with cases. The polymorphism of XRCC7 was determined using an RFLP-PCR method.
Results: The GT (OR= 1.485, 95% CI: 0.765-2.334, P=0.243) and TT (OR= 1.655, 95% CI: 00.875-3.128, P=0.121) genotypes had no significant effect on risk of ALL, in comparison with the GG genotype. Hence, TT genotype (OR= 1.996, 95% CI: 1.033-3.858, P=0.04) after adjusting for parents smoking pattern showed a significant effect.
Conclusion: The presence of the TT genotype may be increase the risk of ALL in children when facing with a Tobacco smoke.
