Pricing Comments

This test is also offered via our exome backbone with CNV detection (click here). The exome-based test may be higher priced, but permits reflex to the entire exome or to any other set of clinically relevant genes.

An additional 25% charge will be applied to STAT orders. STAT orders are prioritized throughout the testing process.

Turnaround Time

18 days on average for standard orders or 13 days on average for STAT orders.

Please note: Once the testing process begins, an Estimated Report Date (ERD) range will be displayed in the portal. This is the most accurate prediction of when your report will be complete and may differ from the average TAT published on our website. About 85% of our tests will be reported within or before the ERD range. We will notify you of significant delays or holds which will impact the ERD. Learn more about turnaround times here.

Clinical Features and Genetics

Clinical Features

Hereditary breast and ovarian cancer (HBOC; OMIM 114480) is characterized by tumors located in the breast and ovary that show familial inheritance. Approximately 5-10% of breast and ovarian cancer cases are the result of genetic predisposition due to gene-specific variants. Tumors tend to occur at an earlier age (i.e. < 50 years) and occur bilaterally; males with breast cancer should also be tested for germline breast cancer variants. There is also a higher predisposition of HBOC in specific ethnicities, such as the Ashkenazi Jewish population (Petrucelli et al. GeneReviews. 2011). Early detection of germline variants in HBOC can be used for prophylactic mastectomy or oophorectomy which may reduce the morbidity and mortality of these conditions.


Hereditary breast and ovarian cancers (HBOCs) are mainly caused by variants in the BRCA1 and BRCA2 genes (Miki et al. Science 266:66-71, 1994; Wooster et al. Nature 378:789-792, 1995), which are tumor suppressors that are involved in cellular proliferation and DNA repair. BRCA1-associated RING domain 1 (BARD1, OMIM 601593), also a tumor suppressor, is involved in the development of hereditary breast and ovarian cancer in a minority of cases. The BARD1 protein interacts with both BRCA1 and BRCA2 proteins. BARD1 aids in BRCA1 stability, nuclear localization and E3 ubiquitin ligase function (Irminger-Finger. Gynecologic Oncology 117:211-215, 2010). HBOC is inherited in an autosomal dominant manner and presents with incomplete penetrance. The most prominent variants in BARD1 are missense variants. Nonsense, splice site, small insertions and deletions, and large deletions are less frequent (Human Gene Mutation Database).

Clinical Sensitivity - Sequencing with CNV PG-Select

Analytical sensitivity should be high because the majority of variants reported are readily detectable by gene sequencing. Clinical sensitivity is low because HBOC has multiple underlying causes including environment and genetics, and BARD1 variants have only been reported in a minority of cases. (De Brakeleer et al. Hum Mutat 31(3):E1175, 2010). Large duplications and deletions have been infrequently reported.

Testing Strategy

This test provides full coverage of all coding exons of the BARD1 gene, plus ~10 bases of flanking noncoding DNA. We define full coverage as >20X NGS reads or Sanger sequencing.

Indications for Test

Individuals with a clinical presentation or family of hereditary breast and ovarian cancer and have tested negative for BRCA1 and BRCA2 gene variants. Males with breast cancer and individuals with an Ashkenazi descent with a concern for HBOC should also be tested. Earlier detection of clinical abnormalities may lead to earlier treatment and better outcomes. Similar to BRCA variant testing, this is a predictive test and provides only information regarding the likelihood of breast and/or ovarian cancer. This test is specifically designed for heritable germline variants and is not appropriate for the detection of somatic variants in tumor tissue.
