Derived
Associated cancers (16)
Cancers mapped in ACCEPTED CIViC predictive, prognostic or diagnostic items whose variant (molecular markers) or gene (gene-level markers) is in this biomarker's scope. Counts by type and native level; each row links to the cancer's evidence tab.
| Cancer | Items | Predictive | Prognostic | Diagnostic | Levels A / B / C / D / E |
|---|---|---|---|---|---|
| Malignant Ovarian Neoplasm | 13 | 12 | 1 | — | 4 / 8 / 1 / 0 / 0 |
| Malignant Pancreatic Neoplasm | 4 | 4 | — | — | 0 / 4 / 0 / 0 / 0 |
| Ovarian Carcinoma | 4 | 3 | 1 | — | 1 / 3 / 0 / 0 / 0 |
| Malignant Prostate Neoplasm | 3 | 2 | 1 | — | 0 / 2 / 1 / 0 / 0 |
| Triple-Negative Breast Carcinoma |

Drugs with predictive evidence (15)
Therapies named in in-scope PREDICTIVE CIViC items, plus targets of PREDICTS_RESPONSE_TO knowledge edges from in-scope variants. Sensitivity and resistance are counted separately and never merged into a verdict.
| Drug | CIViC items | Sensitivity | Resistance | Best level | Edges (S / R) | Cancer context |
|---|---|---|---|---|---|---|
| OlaparibSmall Molecule | 22 | 21 | 1 | A | 21 / 1 | Breast Carcinoma, Castration-Resistant Prostate Carcinoma, Lung Carcinoma, Malignant Biliary Tract Neoplasm +9 |
| RucaparibSmall Molecule | 7 | 7 |

Regulatory
Approvals mentioning the linked drugs (179)
Approval records of the derived drug set, plus records whose indication text names this biomarker. Each record names its authority, jurisdiction, indication text and status — a drug approved in one jurisdiction for one indication is not 'approved' in general, and an approval listed here is not necessarily restricted to this biomarker.
