Pricing Comments

We are happy to accommodate requests for testing single genes in this panel or a subset of these genes. The price will remain the list price. If desired, free reflex testing to remaining genes on panel is available.

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

This panel analyzes 7 clinically actionable high-risk breast cancer susceptibility genes: BRCA1, BRCA2, CDH1, PALB2, PTEN, STK11, and TP53 (Turnbull and Rahman. 2008. PubMed ID: 18544032; Manahan et al. 2019. PubMed ID: 31342359; Pluchino et al. 2020. PubMed ID: 32298647). Pathogenic variants in these genes may confer up to or greater than a 60% lifetime risk of breast cancer (Mavaddat et al. 2013. PubMed ID: 23628597; Mai et al. 2016. PubMed ID: 27496084; Xicola et al. 2019. PubMed ID: 31296550; Wendt and Margolin. 2019. PubMed ID: 30606073). Medical society guidelines are available for all the genes included on this panel.

The genes on this panel are typically associated with early-onset breast cancer (≤45 years of age), bilateral or multiple primary breast cancers, early-onset ovarian cancer (including fallopian tube and primary peritoneal cancers), male breast cancer, or a family history of breast or other early-onset cancers. Variants in some genes are also more frequent in individuals of Ashkenazi Jewish ancestry (Pruthi et al. 2010. PubMed ID: 21123638; Petrucelli et al. 2022. PubMed ID: 20301425). Genetic testing of individuals with a clinical indication for hereditary breast cancer in high-penetrance genes may inform genetic counseling, screening, prevention strategies, and treatment as well as identify at-risk family members (Manahan et al. 2019. PubMed ID: 31342359; Pluchino et al. 2020. PubMed ID: 32298647).

The genes included on this panel may be associated with susceptibility to other cancers, as well as rare cancer syndromes associated with increased risk of breast cancer. These syndromes include diffuse gastric and lobular breast cancer syndrome, hereditary breast and ovarian cancer (HBOC), Li-Fraumeni syndrome, Peutz-Jeghers syndrome, and PTEN hamartoma syndrome. BRCA1BRCA2, and PALB2 are also associated with a rare autosomal recessive condition, Fanconi anemia, which may pose a risk to offspring if an individual’s partner is also a carrier.

Genetics

Hereditary cancers associated with genes on this panel typically have an early age of onset and display autosomal dominant inheritance, although penetrance is incomplete (BRCA1BRCA2CDH1PALB2PTENSTK11, and TP53). In addition to autosomal dominant inheritance, autosomal recessive inheritance is also reported for BRCA1, BRCA2, and PALB2. Most pathogenic variants in these genes are inherited from one or both parents. In some instances, pathogenic variants may arise de novo (PTEN and TP53, for example).

The genes on this panel are involved in DNA repair, cell cycle checkpoint regulation, maintenance of genomic stability, and other biological functions (Lee and Muller. 2010. PubMed ID: 20719876).

See individual gene summaries for information about the molecular biology of gene products and spectra of pathogenic variants.

Clinical Sensitivity - Sequencing with CNV PG-Select

The prevalence of germline BRCA1 or BRCA2 pathogenic variants in the general population is 1:400 to 1:500 (Petrucelli et al. 2022. PubMed ID: 20301425). Certain ancestral populations have significantly elevated prevalence rates for BRCA1 and BRCA2, such as the Ashkenazi Jewish population (1:40) and the Inuit population from Ammassalik, Greenland (1:10 to 1:100) (Petrucelli et al. 2022. PubMed ID: 20301425). Pathogenic variants in genes other than BRCA1 and BRCA2 are often tested selectively. Although individually these genes may be involved in a minority of inherited breast cancer genes, the combination of these high-risk genes may be responsible for a significant portion of hereditary breast cancer (Turnbull and Rahman. 2008. PubMed ID: 18544032).

Testing Strategy

This test is performed using Next Generation Sequencing (NGS) with additional Sanger sequencing as necessary.

This panel typically provides 100% coverage of all coding exons of the genes plus 10 bases of flanking noncoding DNA in all available transcripts along with other non-coding regions in which pathogenic variants have been identified at PreventionGenetics or reported elsewhere. Coverage is defined as ≥20X NGS reads or Sanger sequencing.

Indications for Test

Testing may be considered for individuals with:

  • Early onset breast cancer (≤45 years of age)
  • Early onset ovarian cancer (including fallopian tube and primary peritoneal cancers)
  • Bilateral or multiple primary breast cancers
  • Male breast cancer
  • With breast cancer of Ashkenazi Jewish ancestry
  • A family history of hereditary cancer

This test is specifically designed for heritable germline variants and is not appropriate for the detection of somatic variants in tumor tissue.

This is a predictive test which only provides information regarding the likelihood of breast cancer (or other types of cancer). A positive test does not mean that a person will develop breast cancer. A negative test does not mean that a person will not.
