BRCA1 and neoplasm: The general distribution of the genomic aberrations was relatively similar between the two tumor groups and showed a high proportion of gains and losses in both BRCA1-mutated and non-mutated TNBC (mutated TNBC: mean 102 aberrations per genome, range 18 to 211; non-mutated TNBC: mean 134 aberrations per genome, range 14 to 246).
