Abstract

The nuclear receptor coactivator 7 (NCoA7) gene codes for an estrogen receptor-associated protein that plays a significant role in the cellular response to estrogens. Given that NCoA7 is expressed in the mammary gland, alterations in this gene may affect breast cancer risk. In this study, we compared the genotype and allele frequencies of the missense single nucleotide polymorphism (SNP) rs1567, located in the coding region of the NCoA7 gene and resulting in an amino acid exchange from asparagine to glutamine, in 305 women with sporadic breast cancer and 346 women without any malignancy. Statistical analysis of the observed frequencies did not reveal a significant difference between the cancer and control groups, nor did a comparison between histological breast cancer subgroups. In conclusion, the results of our phenotype-genotype association study indicate that NCoA7 SNP rs1567 does not affect breast cancer susceptibility.
