RESUMO
<p><b>OBJECTIVE</b>To investigate the relationship between C923T (Ala308Val) polymorphism in exon 10 of protein 47000 phagocyte oxidase(p47(phox)) gene and stroke and to evaluate the effect of C923T (Ala308Val) polymorphism on plasma lipid levels in Hunan Hans population.</p><p><b>METHODS</b>Hunan Han population C923T (Ala308Val) polymorphism in p47phox gene was determined by PCR-single strand conformation polymorphism analysis and DNA sequencing in 100 healthy controls, 220 patients with stroke, and 10 stroke pedigrees. Plasma lipid levels were measured by routine methods.</p><p><b>RESULTS</b>No statistically significant differences were found in frequencies of genotypes and alleles of C923T (Ala308Val) polymorphism between the controls and stroke patients (P > 0.05). The serum levels of triglyceride in cerebral infarction patients and controls with CT genotype were markedly higher than those with CC genotype (P < 0.05).</p><p><b>CONCLUSION</b>There is no association between C923T (Ala308Val) polymorphism and stroke in Hunan Hans; C923T (Ala308Val) polymorphism is associated with plasma lipid metabolism in Hunan Han population with cerebral infarction.</p>
