How do Reliant panels enable more patients that meet criteria to get ahead of cancer?
Do professional societies recognize the utility of multigene hereditary cancer screening?
Can Reliant accurately detect whether a specific genetic variant is present or absent?
Are the genetic variants analyzed by Reliant associated with an increased risk for cancer?
Does Reliant provide information that leads to interventions and improved outcomes?
Our thoughtful panel design and clinical rigor allow for more comprehensive identification and opportunities for better management among clinically appropriate patients, compared to single-gene testing. We provide support to providers and patients before and after screening; from identifying clinically appropriate patients to ensuring patients understand their result via our genetic counseling services.
Population with Established Medical Necessity
Reliant is appropriate for use in individuals meeting National Comprehensive Cancer Network (“NCCN”) criteria based on a personal or family history suggestive of a hereditary cancer syndrome.
Clinically Actionable Results
Reliant panels are focused on genes associated with high or moderate lifetime cancer risks and all have management guidelines developed by NCCN and other professional societies.
Support at Every Step
Automated tools help to identify high-risk patients, deliver pre-test education, and provide post-test genetic counseling. These tools aid patients and providers throughout the hereditary cancer screening process.
Includes 19 genes associated with breast, ovarian, endometrial, and other gynecological cancers.
Includes 17 genes associated with gastric, colorectal, and other gastrointestinal cancers.
Includes 29 genes associated with breast, gynecological, gastrointestinal, prostate, thyroid, melanoma and other cancers.
While BRCA1 and BRCA2 account for a large percentage of hereditary breast cancer, variants in several other genes can also increase lifetime breast cancer risk. These genes also have established management guidelines.2-9
Lifetime breast cancer risk for genes commonly tested on multigene panels
*Providers are recommended to discuss risk-reducing mastectomy.
Our CLIA-certified, CAP-accredited, NYS-permitted clinical genomics laboratory is among the most automated and advanced in the world, allowing for reduced costs and rapid turnaround times. Our next generation sequencing platform is scientifically validated, with >99.99% sensitivity, specificity, and accuracy.18
Each gene on the Reliant Cancer Screen has an established association for at least one type of cancer.19
A Critical Measure of Clinical Validity
Curation refers to classification of novel variants as pathogenic, benign, or unknown. Counsyl has developed a robust curation program that is 99% concordant with public databases and other laboratories that share variant data publically.20 The variant curation team is made up of 30 expert variant curators with over 120 years of combined curation experience.
Variants of Uncertain Significance (VUS)
VUS have been cited as a limitation of hereditary cancer panels. Importantly, it is recommended that patients with VUS be managed just as patients with negative results, i.e. based on their personal and family history.21 This important management information is included in Reliant reports.
Interventions, such as increased surveillance and prophylactic surgery, have demonstrated a reduction in cancer morbidity and mortality for well-established syndromes, such as hereditary breast and ovarian cancer (HBOC) and Lynch syndrome.22-25
Interventions are proven to reduce risk
Breast cancer risk
Ovarian cancer risk
High Risk Screening
Breast cancer mortality
Colon cancer mortality
Greater than 90% of positive results from multigene panels impact clinical management when limited to genes with management guidelines and performed in patients with qualifying personal and family history.26
Guideline based management of more recently discovered syndromes with risks similar to those of HBOC and Lynch syndrome is expected to result in similar reductions in cancer risk, as well as morbidity and mortality.27,28
