According to a sequencing study conducted by Welsh et al. for 360 cases of primary ovarian, peritoneal, or fallopian tube carcinomas, irrespective of the family history, 24% of the cases carried germline loss-of-function variants of either BRCA1, BRCA2, or other genes, including those involved in HR pathways such as CHEK2, MRE11A, NBS1 (NBN), RAD50, RAD51C, or in the FA pathway such as BRIP1/FANCJ, PALB2/FANCN, and BARD1. This evidence concerns the gene PALB2 and fallopian tube carcinoma.
