The hypothesis being tested in this project is that a greater proportion of African-Americans with breast cancer harbor a specific germline genetic alteration in the ATM gene or possess a particular ATM haplotype compared to African-American women without breast cancer. An additional objective is to determine the functional impact upon the protein encoded by the ATM gene for each mutation identified. Specific Aims The specific aims of this project are to 1 screen 100 African-American breast cancer patients and 100 African-American women without breast cancer and 2 perform functional studies using cells from patients identified as ATM carriers to determine whether each ATM genetic variant identified affects radiosensitivity and levels of the protein encoded by the ATM gene for each mutation examined.
