Detection of Germline BRCA1 Mutations in Breast Cancer Patients by Quantitative Messenger RNA in situ Hybridization
Mutations in the breast cancer susceptibility gene 1 (BRCA1) may account for one half of all familial breast cancers. Because of the wide spectrum of different germline mutations, identification of BRCA1 mutation carriers using current techniques is laborious and difficult. The majority of the identified mutations, however, lead to aberrant expression of the gene product in tumor tissue, potential
