BRCA1 is a tumour-suppressor gene involved in DNA repair by homologous recombination. Pathogenic variants confer a high risk of breast and ovarian cancer (HBOC syndrome) and an increased risk of prostate and pancreatic cancer.

InheritanceAutosomal dominant
Clinical spectrumBreast, ovary, prostate, pancreas (HBOC)
ManagementEnhanced surveillance (breast MRI), risk-reducing surgery (mastectomy, salpingo-oophorectomy), PARP inhibitors.
