Although there is evidence of DNA damage in experimental stroke, no data exist on DNA repair and stroke in human populations.<\/jats:p>\n               <jats:p>\n                  <jats:bold>Aim:<\/jats:bold> To assess the risk of stroke conferred by polymorphisms in the DNA repair genes, XRCC1, XPD23 and APE\/ref-1 in a cohort of individuals originally assembled as subjects in two cancer prevention trials in Linxian, China.<\/jats:p>\n               <jats:p>\n                  <jats:bold>Methods:<\/jats:bold> The subjects for this prospective study were sampled from a cohort of 4005 eligible subjects who were alive and cancer free in 1991 and had blood samples available for DNA extraction. Using real-time Taqman analyses, all incident cases of stroke (n\u200a=\u200a118) that developed from May 1996, and an age- and a sex-stratified random sample (n\u200a=\u200a454) drawn from all eligible subjects were genotyped. Cox proportional hazards models were used to estimate relative risks (RRs) and 95% CIs.<\/jats:p>\n               <jats:p>\n                  <jats:bold>Results:<\/jats:bold> No association was observed between polymorphisms in APE\/ref-1 codon 148 and XRCC1*6 codon 194, and stroke. Polymorphisms in XRCC1*10 codon 399 were associated with a significantly reduced risk of stroke (RR 0.59, 95% CI 0.36 to 0.96, p\u200a=\u200a0.033), whereas XPD23 codon 312 was associated with a significantly increased risk of stroke (RR 2.18, 95% CI 1.14 to 4.17, p\u200a=\u200a0.010).<\/jats:p>\n               <jats:p>\n                  <jats:bold>Conclusions:<\/jats:bold> Polymorphisms in DNA repair genes may be important in the aetiology of stroke.
