Although this frequency can be overestimated due to the limitation of a small sample size, the association of ovarian carcinosarcomas with BRCA1/BRCA2 pathogenic variants has already been described in the literature (20–22), including two (17%) out of 12 ovarian carcinosarcomas, one with a germline and the other with a somatic mutation. Here, BRCA1 is linked to ovarian carcinosarcoma.
