Abstract

OBJECTIVE: To determine whether polymorphisms in interleukin-1B gene promoter -31 and exon 5 +3953 loci are associated with coronary heart diseases (CHD) in Chengdu Han population. METHODS: Two SNPs of IL-1B gene (+3953C/T and -31T/C) in 100 patients with CHD (CHD group) and 144 healthy controls in Chengdu were analysed using polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP). RESULTS: Two genotypes at IL-1B + 3953 locus (CC and CT) and 3 genotypes at IL-1B -31 locus (CC, TC and TT) were identified. The -31T alleles carriers were associated with a significantly increased risk of CHD as compared with the non-carriers (OR = 2.12, 95% CI: 1.45-3.09, P < 0.01). Genotypes and allele frequencies at IL-1B + 3953 locus in CHD cases did not differ from the controls. CONCLUSION: IL-1B -31T/C polymorphism may contribute to the risk of developing CHD in Chengdu Han population.
