Polymorphism of the XRCC1 Gene Is Associated with Susceptibility and Short-Term Recovery of Ischemic Stroke.

ABSTRACT: Background: Base excision repair (BER) is the primary DNA repair system with the ability to fix base lesions caused by oxidative damage. Genetic variants influencing the BER pathway may affect the susceptibility and the outcomes of ischemic stroke. Here, we examined how single nucleotide polymorphisms (SNPs) associated with BER impact susceptibility and short-term recovery of ischemic stroke. Methods: We selected 320 ischemic stroke patients and 303 controls. Then we genotyped SNPs of NEIL1 rs4462560, NEIL3 rs12645561 and XRCC1 rs25487 in both groups. Results: Polymorphism in XRCC1 rs25487 was significantly associated with reduced ischemic stroke (IS) risk (dominant model: OR = 0.53, 95% CI = 0.36-0.79, p = 0.002), a milder initial stroke (dominant model: OR = 0.57, 95% CI = 0.33-0.98, p =
