The well-known breast cancer specific germline mutations in BRCA1 (185delAG; Chr17: 43124030–43124031 and 5382insC; Chr17: 43057065) and BRCA2 (6174delT; Chr13: 32340301) were not amongst the variants identified in either the GBM cohort or the TCGA-GBM cohort. This evidence concerns the gene BRCA1 and breast carcinoma.
