A paradigm shift
“From Shape To Substance”
Tumors are now characterized based on their biomarkers signature rather than their tissue of origin or morphology. This leads to a more direct and precise treatment plan.

Maximum Precision
with Broad Coverage:
Modern massive parallel sequencing technologies have
given us tremendous capabilities to investigate multiple molecular biomarkers in parallel to reach
results faster on tiny biopsy specimens. Also, multigene panel testing can help identify driver
mutations for which effective drugs may be available. For example, the NCCN makes the following
recommendations for using multi-gene panels in the evaluation of non-small cell lung cancer
(NSCLC): “The NCCN NSCLC Guidelines Panel strongly endorses broader
molecular profiling with the goal of identifying rare driver mutations for which effective drugs
may already be available or to appropriately counsel patients regarding the availability of
clinical trials. Broad molecular profiling is a key component of the improvement of care of
patients with NSCLC.”
Our comprehensive solid tumor panel contains 500+ genes that cover a wide array of alterations, such as:
Single Nucleotide Variants (SNVs), e.g., EGFR T790M.
Insertions & Deletions (InDels), e.g., BRCA1/2 in breast cancer
Copy Number Variants (CNVs), e.g., ERBB2/HER2 amplifications in breast cancer.
Gene Fusions (RNA), e.g., EML4-ALK fusion in NSCLC.
Splice Variants (RNA), e.g., METex14 exon 14 skipping in NSCLC
Microsatellite Instability (MSI), e.g., Lynch syndrome and colon cancer.
Tumor Mutation Burden (TMB), e.g., Mutation per megabyte as a biomarker for immunotherapy.
Somatic and germline Homologous Recombination Deficiency (HRD) and Loss of Heterzygosity (LOH) for assessing eligibility for PARP inhibitors therapy.
HRD
Homologous recombination deficiency
Homologous recombination pathway is a DNA repair pathway that includes BRCA1&2, ATM and several other Loss of Heterozygosity (LOH) genes (including RAD51C, RAD51D, RAD50, BRIP1, BARD1, CHEK2, MRE11A, NBN, PALB2, MLH1, MSH2, MSH6, PMS2, TP53). Mutations of the Homologous Recombination Repair (HRR) gene(s) may result in impaired DNA repair, thereby providing a selective target for cancer cell death (1,2). Poly ADP Ribose Polymerase (PARP) plays an important role in DNA damage repair. Inhibition of the PARP relevant pathway will not result in cell death as the HRR pathway will compensate for the DNA repair process. However, if the HRR pathway is impaired by a mutation in the HRR gene(s), then inhibiting the PARP pathway in the cancer cell will result in cancer cell death(1,2).

Frequently
Asked Questions:
At siParadigm, we use Next Generation Sequencing (NGS) to test for somatic and germline mutations in the homologous recombination repair (HRR) genes including BRCA1/2, ATM and 42 loss of heterozygosity (LOH) genes. These mutations result in genomic instability in breast, ovarian, pancreatic, or prostate cancers. This helps identify subsets of patients who may be eligible for PARP inhibitor therapy or clinical trials.
A positive somatic or germline result qualifies your patient for PARP inhibitor therapy. There are several drugs that have been FDA-approved based on BRCA1/2 mutations and certain cancers. Many clinical trials are under way to approve these and other drugs for other gene mutations in the HRR pathway as well as other cancers (see the table above).
Studies suggest that PARP inhibitors are indicated in cases of germine and/or somatic mutations in the Homologous Recombination Repair (HRR) genes. That is why testing is recommended for both. Please note that germline testing requires written patient’s consent because of its familial implications.
HRR pathway genes have different predictive values for different cancers. In general, the most predictive are BRCA1&2, and to a lesser extent, ATM. However, other loss of heterozygosity (LOH) genes are also pertinent (including BARD1, BRIP1, CDK12, CHEK1, CHEK2, FANCL, PALB2, PPP2R2A, RAD51B, RAD51C, RAD51D, RAD54L, etc.).
