Abstract
Genetic factors including genetic variations in important genes may influence breast cancer susceptibility. One of important gene variations is p53 codon 72 which might impact risk of breast cancer. There are three case-control genetic association studies regard to the relation of this polymorphism with breast cancer risk in Iranian females, but the outcomes are indecisive. So, a meta-analysis was made in Iranian population in this regard. The eligible studies were found using search in appropriate databases. So, the extracted information from comprised studies was examined by Open Meta analyst program. The analyzed data displayed that there is no substantial correlation of p53 codon 72 substitution with risk of breast cancer in CC vs. GG (OR= 0.844, 95%CI= 0.244-2.916, p= 0.789) and GC vs. GG (OR= 1.215, 95%CI= 0.880-1.676, p= 0.237) models in Iran. Regarding to the outcomes, the aforementioned polymorphism is not a molecular risk factor for breast cancer in Iranian population.
