BRCA2

Tumor suppressor; BRCA2-PALB2 complex loads RAD51 onto RPA-coated ssDNA → homologous recombination repair; BRCA2 loss → HRD → PARP inhibitor synthetic lethality. Germline BRCA2 mutations → breast (~50-70% LT risk), ovarian (~10-30%), prostate, and pancreatic cancer risk.

Also known as: BRCA2, FANCD1, breast cancer 2, BRCA2 tumor suppressor, RAD51 loader, HRD, FANCD1 Fanconi anemia
