Background/Aim:
The current study aimed at evaluating the contribution of IL-13 promoter rs1881457 and rs1800925 genotypes to the risk of breast cancer in Taiwan.
Materials And Methods:
A total of 1,232 breast cancer cases and 1,232 age-matched controls were genotyped by typical polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) methodology.
Results:
As for IL-13 rs1881457, the rates of AA, AC and CC genotypes were 54.8, 37.9 and 7.3% among the cases, and 53.8, 38.7 and 7.5% among the healthy controls, respectively; there were no statistically significant differences between the two groups (p for trend=0.8889). Also, regarding IL-13 rs1800925, there were no statistically significant differences between the two groups either (p for trend=0.6803). Furthermore, the allelic frequencies for IL-13 rs1881457 and rs1800925 were not differentially distributed between the case and control groups (p=0.6515 and 0.8753, respectively).
Conclusion:
The rs1881457 and rs1800925 IL-13 promoter polymorphisms may not serve as breast cancer susceptibility determinants for Taiwanese.
