BACKGROUND: Breast cancer is one of the most common cancers among women worldwide. Tumor protein 53 (TP53) and its regulator, the mouse double murine 2 (MDM2) protein homologue, influence tumorigenesis through their key roles in cell division and response to DNA damage. The MDM2 SNP309T>G (rs2279744) polymorphism in the promoter region of the MDM2 can cause dysfunction and inactivation of TP53, which promotes tumor progression. The aim of this study was to investigate the possible association between this polymorphism and breast cancer in a northeastern Iranian population...
