RESUMO
OBJECTIVE: To investigate the relationship between C923T (Ala308Val) polymorphism in the exon10 of P47(phox) gene and cerebral infarction and to evaluate the effect of C923T polymorphism on plasma lipid levels. METHODS: Peripheral blood samples were collected from 110 patients with cerebral infarction, 100 sex and age-matched healthy controls, and 102 members of 10 cerebral infarction pedigrees 19 of which were cerebral infarction patients. The polymorphism in P47(phox) gene was determined by PCR-single strand conformation polymorphism analysis and DNA sequencing. Plasma lipid levels were measured by routine methods. RESULTS: Three gene types, CC, CT, and TT were found in the C923T (Ala308Val) polymorphism site. No statistically significant differences were found in the frequencies of genotypes and alleles of C923T polymorphism between the controls and cerebral infarction patients (all P > 0.05). The serum levels of triglyceride of cerebral infarction patients and controls with the CT genotype were markedly higher than those of the cerebral infarction patients and controls with the CC genotype (both P < 0.05). CONCLUSION: There is no association between the C923T polymorphism and cerebral infarction. C923Tpolymorphism is associated with plasma lipid metabolism.

OBJECTIVE: 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. METHODS: 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. RESULTS: 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). CONCLUSION: 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.
