Breast cancer is one of the most important causes of minatory in women and interleukin 8 gene polymorphism (251 a / t) has a direct impact on the risk of breast cancer. therefore, in this study, was investigated the relationship between breast cancer and 251a / t polymorphism of il-8 gene in iranian females population by tetra arms-pcr.
In this case-control study, 50 women with breast cancer and 50 healthy women as control group were selected. after extraction of dna, determination of il-8 gene 251 a / t polymorphism genotypes was performed by tetra arms-pcr method.
In control group, distributionof il-8 gene 251 a / t polymorphism frequency for aa, at, and tt genotypes was 0%, 88% and 12%, respectively and for cancer group was 12%, 54% and 34%, respectively. statistical analysis in this study showed no significant difference between aa, at and tt genotypes in the control and cancer groups (p> 0.05).
The present study is the first study for relationship between risk of breast cancer and the association of il-8 gene 251 a / t polymorphism in iranian women. the results were indicated that this polymorphism was not associated with breast cancer in this study female patients.
