The association between TP53 gene polymorphisms and breast cancer (BC) in Brazilian women is a controversial topic. In this cross-sectional study, we evaluated the association between clinical pathological variables and three polymorphisms (TP53*11, TP53*72, and TP53*248) in BC patients and controls. Genomic DNA was extracted from the blood cells of 393 participants; the cancer-free control subjects were 26-72 years old (41 ± 11.03) and the BC patients were 28-80 years old (51 ± 10.70). We used standard polymerase chain reaction-restriction fragment length polymorphism and confirmed the results by genetic sequencing. In TP53*11, there was 100% homozygous Glu distribution in both groups. TP53*72 showed genotypic distribution: in the control group, there was 16.10% homozygous Pro, and 42.44% heterozygous and 41.46% homozygous Arg; in the BC group, there was 15.43% homozygous Pro, and 42.55% heterozygous and 42.02% homozygous Arg. The relative frequency of each allele was 0.37% for Pro and 0.63% for Arg in the control group, and 0.37% for Pro and 0.63% for Arg in the BC group. The nuclear grade (P = 0.0084) and adapted histological grade (P = 0.0265) were associated with TP53*72. The distribution of the codon 72 genotypes did not deviate from Hardy-Weinberg equilibrium in either group. In TP53*248, there was 100% homozygous Arg distribution in both groups. In codon 72, the Arg allele is the most prevalent in Brazilian women. TP53*72 may be associated with susceptibility to BC, although more studies are required to evaluate the profile of Brazilian women with BC.
