Association of Interleukin-4 Polymorphisms With Breast Cancer in Taiwan.

ABSTRACT: BACKGROUND/AIM:The present study aimed at evaluating the contribution of IL-4 promoter T-1099G (rs2243248), C-589T (rs2243250), C-33T (rs2070874) genotypes to the risk of breast cancer in Taiwanese. MATERIALS AND METHODS:A total of 1232 breast cancer patients and 1232 age-matched controls were genotyped by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) methodology. RESULTS:Genotypic frequencies of IL-4 rs2243248, rs2243250 and rs2070874 were not differentially distributed between case and control groups. Consistently, there was no difference in the distribution of allelic frequencies among patients and controls. CONCLUSION:IL-4 rs2243248, rs2243250 and rs2070874 do not confer breast cancer susceptibility in Taiwanese.
