Positive association between SRA1 rs801460 variant and proliferative type of benign breast disease with atypia in Ukrainian females.

Aim: To investigate the association between SRA1 rs801460 and rs10463297 variants and proliferative type of benign breast disease with atypia development in Ukrainian females.

Materials and methods: 83 individuals diagnosed with proliferative type of benign breast disease with atypia and 115 without atypia were enrolled in the study. The rs801460 and rs10463297 variants genotyping was performed using polymerase chain reaction-restriction fragment length polymorphism analysis. Hematoxylin and eosin, toluidine blue and van Gieson's picrofuchsin methods were used for sections staining.

Results: It was revealed that SRA1 rs801460-variant is associated with proliferative type of benign breast disease with atypia development both before and after adjustment for risk factors (age, body mass index, age of menarche, oral contraceptives intake and burdened history of breast cancer). The risk for mentioned disease in the individuals with rs801460 TT-genotype is 2.2 times higher (confidence interval 1.010-4.800; p = 0.047) than in individuals with the CC and CT genotypes. No link between SRA1 rs10463297 and proliferative type of benign breast disease with atypia occurrence in Ukrainian females was found.

Conclusion: The present study specified that SRA1 rs801460, but not rs10463297, can be the strong genetic predictor for benign breast disease with atypia in Ukrainian females.
