RESUMO
OBJECTIVE: To investigate the association between the NINJ2 gene rs11833579 polymorphism and stroke in Han Chinese population. METHODS: This study was a population-based cross-sectional case-control study. Polymerase chain reaction-restriction fragment length polymorphism (RFLP) and sequencing were used for the detection of NINJ2 genotypes in 790 patients with stroke (679 ischemic stroke) which were Han Chinese population from Fangshan First Hospital and 811 controls which were healthy Han Chinese population without family history of stroke in Fangshan district rural area. RESULTS: In rs11833579 locus of the NINJ2 gene, the frequencies of GG genotype and allele G were higher in ischemic stroke patients than that in controls (P<0.001). The frequency of allele G of the NINJ2 gene was higher in cerebral hemorrhage patients than that in controls (P=0.005). Genotype had little effect on the glucose, total cholesterol and triglyceride. CONCLUSION: There is significant association between rs11833579 site polymorphism of the NINJ2 gene and risk for stroke in Han Chinese population from Fangshan district.
