Marker at the androgen receptor gene for determining breast cancer susceptibility

摘要

The present invention relates to a method of determining an individual's predisposition to breast cancer, development of breast cancer, protection against breast cancer and/or responsiveness to therapy for breast cancer. The method comprises the step of determining the androgen receptor genotype at the CAG repeat locus of an individual, or at a locus in linkage disequilibrium with the CAG repeat locus, thereby determining an individual's predisposition to breast cancer, development of breast cancer, protection against breast cancer and/or responsiveness to therapy for breast cancer.
