We developed a BRCA-like genomic copy number aberration profile classifier (BRCA-like classifier) that classifies whether a tumor has aberrations similar to those observed in tumors from patients with BRCA1 and BRCA2 germline pathogenic variants.9 The signature is assumed to identify abnormalities like those found in BRCA1/2-mutated tumors and may identify tumors that are HRD. This evidence concerns the gene BRCA1 and neoplasm.
