Whole-genome sequencing of tumour and germline DNA samples from 92 patients with high-grade serous ovarian cancer identifies frequent gene breakages that inactivate the tumour suppressors RB1, NF1, RAD51B and PTEN, and contribute to chemotherapy resistance; acquired resistance was associated with diverse mechanisms such as reversions of germline BRCA1/2 mutations and overexpression of the drug efflux pump MDR1.
