Lack of association between CYP11B2 -344T/C polymorphism and transient ischemic attack in a Chinese population

OBJECTIVE: This study investigated whether the CYP11B2 -344T/C polymorphism is correlated with transient ischemic attack (TIA) susceptibility. METHODS: We recruited 100 TIA patients and 100 control subjects and analyzed the CYP11B2 -344T/C polymorphism using restriction fragment length polymorphism (PCR–RFLP). RESULTS: The frequency in TIA patients and controls was 42% compared with 48% for TT genotypes, 51% compared with 45% for TC genotypes, and 7% compared with 7% for CC genotype, respectively. Allele frequencies in TIA patients and controls were 67.5% compared with 70.5% for T-allele and 32.5% compared with 29.5% for C-allele, respectively. No association between the CYP11B2 -344T/C polymorphism and TIA was observed in all comparisons. CONCLUSION: Our data suggest that there was no association between the CYP11B2 -344T/C polymorphism and TIA in a Chinese population.
