Germline and tumour BRCA1/2 status are highly concordant (i.e., most tBRCAmut alterations are germline) (Vergote et al., 2020), although BRCA1/2 mutations detected in 5%─7% patients with HGSOC are identified in the tumour, but not through germline testing (Callens et al., 2021). Here, BRCA1 is linked to neoplasm.
