GenPath® Oncology, now offers OnkoHRDTM homologous recombination deficiency (HRD) assessment with OnkoSight Advanced® next-generation sequencing (NGS).

  • Measure genomic scars, which are defined by large-scale genomic instability, such as loss of heterozygosity (LOH), telomeric allelic imbalance (TAI), and large-scale state transitions (LST) in addition to the sequencing of the critical genes involved in the homologous recombination repair (HRR) pathway (e.g., BRCA1, BRCA2).
  • Detect abnormalities across the genome, thereby expanding access to HRD status assessment of cancer samples.
  • Interrogate CCNE1 Amplification status, a predictive biomarker for therapy resistance in epithelial ovarian cancer.

Per NCCN®, somatic testing in ovarian cancer should at a minimum include BRCA1/2, loss of heterozygosity (LOH), or HRD status in the absence of a germline BRCA mutation.

In ovarian cancers, HRD serves as a predictive biomarker for PARP inhibitors and a positive prognostic marker for both progression-free survival and overall survival.

FDA-Approved PARP Inhibitors Requiring HRD and/or HRR Gene Mutation Status:

Clients may add OnkoHRDTM (Test code TQ30-1) to any OnkoSight Advanced® panel listed in the table below. OnkoHRD must be ordered concurrently with OnkoSight Advanced® panel (Test code TP57, TH53, TK84, TH48, TJ16, or TM57) or within 30 days of sample receipt at the laboratory.

^Virtual karyotyping or CNA assessment will require samples with >50% tumor content. Normal findings will not be reported. For TJ16, CNA assessment will be performed on samples with an indication for tumor subtypes with HRD- associated therapy including high-grade serous ovarian (HGSO), fallopian tube, primary peritoneal, prostate, breast, and pancreaticobiliary carcinoma.
