Abstract

Background: The incidence rate of BREAST CANCER has been dramatically increasing since the last decade in Iran, and it is now one of the most common female malignant tumors. B‑CELL LYMPHOMA 2 (BCL2) family is the most important regulator of apoptosis, and −938C>A single nucleotide POLYMORPHISM (SNP) of BCL2 gene promoter has been demonstrated to influence BREAST CANCER susceptibility. In this research, we study the effect of −938C>A allelic variants on BREAST CANCER risk in Mazandaran province at the North of Iran. Materials and Methods: This analysis performed on 120 BREAST CANCER patients who underwent surgery in some referenced hospitals at Mazandaran province along with 130 healthy individuals as a control. DNA extracted from peripheral blood samples was applied in POLYMORPHISM/fa?page=1&sort=1&ftyp=all&fgrp=all&fyrs=all" target="_blank"> POLYMERASE CHAIN REACTION‑SINGLE‑STRAND CONFORMATION POLYMORPHISM analysis to determine −938C>A genotype. The association of the −938C>A genotype and BREAST CANCER risk as well as clinicopathological characters were analyzed by logistic regression method.Results: Results showed that genotype frequency of AA, AC, and CC genotypes was 10%, 62%, and 28% for case and 28%, 50%, and 22% in control group, respectively. In the logistic regression model, BCL2 − 938C/A variant genotype AA was associated with a decreased risk of BREAST CANCER (P=0.041) by 0.31‑fold (odds ratio=0.31, confidence interval=0.091–0.909) compared to CC genotype. However, no significant association found between −938C>A genotype and clinicopathological characters.Conclusion: The study showed that AA genotype of BCL2 gene (−938C>A) is associated with decreased susceptibility to BREAST CANCER. Hence, investigating the −938C>A SNP of BCL2 gene promoter could be an appropriate molecular marker to determine individual sensitivity to BREAST CANCER.
