RESUMO
Objective:To evaluate the relationship between 1233A/T polymorphism of proteasome subunit α type 6 (PSMA6) gene and cerebral infarction in Chinese Han population. Methods:From January, 2012 to April, 2015, 211 cerebral infarction patients (case group) and 201 healthy controls (control group) were selected in the study. The single nucleotide polymorphism of 1233A/T of PSMA6 gene was identified by polymerase chain reaction (PCR) and restriction fragment length polymorphism (RFLP), and genotypes and allele frequency distributions in two groups were analyzed. Results:The frequencies of CC, CT+TT genetype and the C allele all revealed no significant difference between two groups (χ2 < 0.053, P > 0.05). After stratified by gender, the difference among all genetypes and C allele were still not significant between two groups in either male or female (χ2 < 2.735, P > 0.05). Conclusion:The 1233A/T of PSMA6 gene might not be associated with cerebral infarction.
