Association between VDR Gene Polymorphisms (<i>rs 1544410</i>, <i>rs 7975232</i>, <i>rs 2228570</i>, <i>rs 731236</i> and <i>rs 11568820</i>) and Susceptibility to Breast Cancer in a Sample of Southeastern Iranian Population
Journal Title: International Journal of Cancer Management - Year 2017, Vol 10, Issue 3
Abstract
Background Vitamin D receptor (VDR) is a key nuclear receptor that is associated with the risk and progression of breast cancer (BC). Objectives The present study investigated the <i>Fok1</i>, <i>Bsm1</i>, <i>Taq1</i> and <i>Cdx2</i> polymorphisms in the VDR gene and susceptibility to BC in a sample of Southeastern Iranian population. Methods This case-control study was conducted on 180 women with BC and 178 age-matched healthy women. RFLP-PCR method was used for analysis of <i>Bsm1</i> (<i>rs 1544410</i>), <i>Apa1</i> (<i>rs 7975232</i>), <i>Fok1</i> (<i>rs 2228570</i>) and <i>Taq1</i> (<i>rs 731236</i>) and also TETRA-ARMS method for <i>Cdx2</i> (<i>rs 11568820</i>). Results No significant correlation was found between polymorphisms of <i>Taq1</i>, <i>Fok1</i> and Apa1 with BC, but was for <i>Bsm1</i> (odds ratio (OR) = 3.452, 95% CI 1.769 - 6.738; P < 0.001). Also, there was a significant correlation between the case and control groups for <i>Cdx2</i> (OR = 3.720, 95% CI 2.224 - 6.225; P < 0.001) and allele A in <i>Cdx2</i> had just significant correlation with BC. Conclusions The present study findings showed that there were significant correlations between <i>Bsm1</i> and <i>Cdx2</i> polymorphisms with BC in women of Sistan and Baluchestan Province (southeastern Iran). Also, signals of <i>Rs1544410-Bsm1</i> and <i>Rs11568820-Cdx2</i> positions were difference with routes of estrogen and progesterone per person and they probably act independently.
