The Effect of Polymorphisms on the Ala 119 Ser Gene Cytochrome P450 1B1*2 on the Susceptibility of Iranian Women to Develop Breast Cancer
Journal Title: International Journal of Cancer Management - Year 2017, Vol 10, Issue 3
Abstract
Background Cytochrome P450 IBI (CYP1B1) is involved in the metabolism of a wide range of internal and external substrates and also plays a key role in the metabolism of oestrogen. This enzyme is a factor that could potentially affect the likelihood of a person developing breast cancer. The aim of this study was to evaluate the correlation between polymorphism (RS1056827) and the occurrence of breast cancer in Iranian women. Methods We used a case-control study design. After an initial evaluation, 79 women with breast cancer (the patient group) and 79 women without breast cancer (the control group) were selected to participate in the study. Their blood samples were then obtained, and a sample of their DNA was extracted. PCR-RELP was used to determine the genotypes of the participants. The data were subjected to statistical tests using the SPSS software package. Results The results demonstrated that the frequency of the G allele in the patient and the control group were 34% and 69%, respectively. In addition, the frequency of the T allele in the patient and control group were 66% and 31%, respectively. The genotype frequency of TT, GG and TG in patients with breast cancer were 26.59%, 20.25% and 53.16%, respectively, and 22.79%, 60.76% and 16.45%, respectively, in the control group. There was a statistically meaningful correlation between the results of the genotypes in the patient and control groups. Conclusions The results demonstrated that patients with the TT genotype are 3.85 times more likely to develop breast cancer. Therefore, the presence of this polymorphism could be one of the factors that lead to the development of breast cancer.
