Influence of VDR gene polymorphisms on the development and course of breast cancer

Abstract

Annotation. Breast cancer is the most common cancer diagnosed in women. In the last 5 years, it has been diagnosed in 7.8 million women, and in 2020, 685,000 deaths from breast cancer were registered. The growing number of patients with this pathology and the cost of therapy creates a need to study new methods of diagnosis and treatment. Therefore, detailed attention is paid to genetic risk factors for cancer, in particular, the VDR gene and its polymorphisms ApaI, TaqI, BsmI and FokI. Therefore, the purpose of this review is to collect and analyze currently known information about these SNPs and their relationship to the development, course and effectiveness of breast cancer treatment. To do this, an extensive literature review was conducted using basic databases, which described the effect of vitamin D3 on the tumor process and found that VDR receptor dysfunction increases the risk of breast cancer and affects the sensitivity of patients to treatment, which proves the effect of polymorphisms. ApaI, TaqI, BsmI and FokI on the development of pathology. Therefore, the prospects for further research are to study the prognostic value of each polymorphism and develop new treatments for the disease.
