Biomarker · HR deficiency

Homologous recombination deficiency (HRD)

A genomic scar signature (loss of heterozygosity, telomeric allelic imbalance, large-scale state transitions) and/or deleterious BRCA1/2 status estimated from tumor sequencing; used as a predictive marker for PARP inhibitors in ovarian cancer.

Derived

Associated cancers (0)

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.

Drugs with predictive evidence (0)

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.

Curated evidence

Predictive evidence items (0)

ACCEPTED CIViC predictive items in scope, grouped by molecular profile and therapy with native level, direction and cancer context. 50 per page.

Approvals mentioning the linked drugs (3)

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.
