Response to commentary article: "The association between Interleukin-1β gene rs1143634 polymorphism and the risk of breast cancer by Bei Wang, Fenlai Yuan".
Mutant allele and genotype at IL-1β [+3954 C>T (rs1143634)] site associated with increased BC risk, while mutant allele and genotypes at IL-6 [-174 G>C (rs1800795)] polymorphism appeared to be protective.
We found that the variant CC genotype of rs1143627 was associated with a significantly increased breast cancer risk (CC vs. TT: OR = 1.37, 95% CI = 1.10-1.70, P = 0.22 for heterogeneity; the recessive model CC vs. TT/TC: OR = 1.40, 95% CI = 1.17-1.67, P = 0.49 for heterogeneity).
