Mutations of the Bax gene are known to af- fect protein expression and function. A promotor polymorphism G(£­248)A in the 5¡¯UTR of Bax gene may alter regulation of apoptosis in carcinogenesis. Our study was performed to test the association be- tween G(£­248)A polymorphisms in the Bax gene and breast cancer risk and progression. G(£­248)A poly- morphism was genotyped in a Turkish breast cancer, case-control population including 53 female cancer patients (mean age ¡À SD: 60.9 ¡À 11.9 years) and 82 controls (mean age ¡À SD: 57.2 ¡À 17.5 years) using PCR-RFLP analysis. Genotype and allele frequencies were assessed with the chi-square test. There was no difference in the distribution of Bax genotypes, and allele frequencies were G (87.7% versus 88.4%) and A (12.3% versus 11.6%) in the cancer patients and controls, respectively. Within the cancer group, the presence of a polymorphic Bax G(£­248)A allele was not associated with clinico-pathological parameters such as advanced tumor stage, lymph node or distant metastasis. We present the first to report on Bax G(£­248)A polymorphisms in breast cancer. Our re- sults suggest that Bax G(£­248)A polymorphism do not modify individual susceptibility to invasive breast cancer in Turkish women. %K Bcl-2 Associated-X-Protein %K SNP %K Apoptosis %K PCR %K Susceptibility %K Carcinogenesis %U http://www.scirp.org/journal/PaperInformation.aspx?PaperID=26993
