BRCA1 and neoplasm: While we cannot exclude that our phenotype segregates with the BRCAness phenotype in its full extent, the comparable distribution of BRCA1/2 mutations among FI-like and OSE-like HGSOC should orient future studies towards the dissection of the role that other alterations in the DDR pathway may potentially contribute to the difference in survival between patients affected by two tumor subtypes that we identified.
