Genetic Testing for Breast, Ovarian, Pancreatic and Prostate Cancers (BRCA) AHS - M2003

Description of Procedure or Service

BRCA1 and BRCA2 are two distinct tumor suppressor genes involved in a common DNA repair process (Roy et al., 2012). Germline mutations of BRCA genes are associated with an increased risk of breast and ovarian cancer, as well as other cancer types including pancreatic, and prostate cancer to a lesser extent (Paul & Paul, 2014).

“Prior to 2020, the NCCN Guidelines for Genetic/Familial High-Risk Assessment: Breast and Ovarian (Breast, Ovarian, and Pancreatic as of 2020) focused largely on testing criteria for BRCA1/2 and appropriate risk management for carriers of a BRCA1 or BRCA2 P/LP variant. Sections on LFS and Cowden syndrome/PTEN hamartoma tumor syndrome (PHTS) were also included. Based on strong evidence that genes beyond BRCA1/2, TP53, and PTEN confer markedly increased risk of breast and/or ovarian cancers, these Guidelines have been expanded” (NCCN, 2023b) to include BRCA1, BRCA2, CDH1, PALB2, PTEN, and TP53 as high-penetrance breast cancer susceptibility genes, as well as some moderate-penetrance susceptibility genes. These susceptibility genes are often found on multi-gene panels, in addition to BRCA1/2.

Policy Guidelines

BRCA1 and BRCA2 are critical genes in the process of homologous recombination repair of double-strand DNA breaks (Walsh, 2015) Both genes are very large (occupying about 70 kb) and encode a combined total of 49 exons. They are considered tumor suppressor genes and a loss of function on either gene increases the cancer risk (Pan & Xie, 2017). BRCA1 is thought to regulate c-Abl kinase activity (as loss of BRCA1 results in a constitutively activated c-Abl kinase) whereas BRCA2 is thought to regulate Rad51, which repairs DNA damage such as chromosomal breaks (Yoshida & Miki, 2004). 

Different regions of mutation may confer different types of risk. For example, BRCA2 has an area called the ovarian cancer cluster region (OCCR) in which mutations predispose the patient for ovarian cancer. Mutations outside the OCCR are more likely to result in breast cancer compared to mutations in the OCCR. On BRCA1, mutations closer to the 3’ end of the gene may result in higher risk than mutations closer to the 5’ end (Meric-Bernstam et al., 2013). Other gene defects that affect homologous recombination include hypermethylation of RAD51C or ATR mutation. However, these are considered to have a phenotype of “BRCAness” and behave like BRCA-deficient genes even if the BRCA gene itself is normal (Walsh, 2015).

Although the probability of cancer development in carriers is variable, estimates of penetrance in individuals with a pathogenic variant in BRCA1 or BRCA2 range from 46% to 87% lifetime risk for breast cancer, and 16.5% to 63% lifetime risk for ovarian cancer (Petrucelli et al., 2016). BRCA1 and BRCA2 mutations account for about 5 – 10% of breast cancers and 10 – 18% of ovarian cancers (Walsh, 2015). BRCA mutations are inherited in an autosomal dominant fashion and are highly penetrant (Isaacs & Peshkin, 2024).

It is clinically important to recognize these carriers to guide management of cancer and identify unaffected women with a BRCA mutation who will benefit from enhanced surveillance, tailor care to improve outcomes, and more efficiently use health-care resources. This has the potential to have a significant individual and population health impact on morbidity and mortality if these women adhere to guidelines for managing cancer risk (Buchanan et al., 2017). For example, BRCA deficient cancers are often targeted for a certain class of drugs called poly(ADP-ribose) polymerase (PARP) inhibitors. These inhibitors target enzymes responsible for the base excision repair pathway. A cell can survive with the loss of either the base excision repair pathway or the homologous recombination mechanism, but not both. Since BRCA-deficient cells already have a faulty homologous recombination mechanism, the BRCA-deficient cell dies when the PARP inhibitor shuts down the base excision repair pathway. BRCAdeficient cells have been shown to be affected 1000 times more by these PARP inhibitors than wild-type cells (Walsh, 2015).

Numerous proprietary tests exist for the assessment of BRCA or its related genes such as RAD51. For example, gene panels such as Ambry Genetics’ panel include 25 genes such as BRCA1, BRCA2, CHEK2, ATM, RAD51C, and BRIP1. This test is performed by next generation sequencing or Sanger sequencing (except for EPCAM) with a turnaround time of 2-3 weeks. Ambry has several proprietary tests such BRCAplus and BreastNext (Ambry, 2023). Another gene panel that has been developed to identify genetic mutations associated with inherited breast and ovarian cancers is the AmpliSeq for Illumina BRCA Plus, Extended Hereditary Breast and Ovarian Research Panel. This panel assesses germline variants in 11 genes known to harbor mutations related to breast and ovarian cancer: ATM, BRCA1, BRCA2, CHEK2, PALB2, RAD51C, RAD51D, NBN, CDH1, SMARCA4, and TP53. However, though these community panels boasts the convenience of being made-to-order, Illumina warns that they do not have associated performance metrics (Illumina, 2021). myChoice CDx by Myriad Genetics, Inc. is a tumor test that determines homologous recombination deficiency status by detecting BRCA1 and BRCA2 (sequencing and large rearrangement) variants. This next generation sequencingbased in vitro diagnostic assay focuses on assessing genomic instability by using loss of heterozygosity, telomeric allelic imbalance and large-scale state transitions from tumor tissue specimens. The results can then be used to guide treatment and therapy for ovarian cancer patients with positive homologous recombination deficiency, which is defined by the presence of BRCA1/2 mutations and/or positive Genomic Instability Score (Myriad Genetics, 2024).

Clinical Utility and Validity

A study performed by Kuchenbaecker et al. (2017) assessed the cumulative risk of breast and ovarian cancer based on mutation position. A sample of 9856 patients was analyzed, with 6036 patients carrying a BRCA1 mutation and 3820 with a BRCA2 mutation. 5046 patients were unaffected by either type of cancer and 4810 had breast cancer, ovarian cancer, or both at baseline. The breast cancer assessment was based on 3886 carriers, and the ovarian cancer assessment was based on 5066 women. The authors evaluated the cumulative risk of breast cancer to 80 years to be 72% for BRCA1 mutation carriers and 69% for BRCA2 carriers. Cumulative risk for ovarian cancer to 80 years was found to be 44% for BRCA1 carriers and 17% for BRCA2 carriers. BRCA2 mutations outside the OCCR were found to have a higher risk of breast cancer than mutations inside it (hazard ratio: 1.93 for OCCR ranges 5′ to c.2830, c.2831 to c.6401, c.6402 to 3) but no difference in overall ovarian cancer risk. Mutations closer to the 3’ or 5’ ends of BRCA1 were found to have a higher risk of breast cancer compared to the middle third of the gene and the third closest to the 3’ end had the highest hazard ratio of 1.51 compared to the third closest to the 5’ end (1.43) (Kuchenbaecker et al., 2017).

A meta-analysis of 44 articles was performed to assess the difference in risk factors between BRCA1 and BRCA2 carriers. Factors such as breastfeeding, coffee, infertility, and more were examined between both genotypes, and the only risk factor that revealed an association of any kind was age at first live birth for BRCA1 carriers. Breast cancer risk was found to decrease for BRCA1 women over 30 compared to women under 30, and the same was found for women from 25-29 compared to women under 25. However, the authors stressed that more research was required (Friebel et al., 2014).

However, the importance of BRCA testing has not only been explored for lifestyle choices or transient states; factors such as ethnicity can also play a role in the predisposition of patients to breast cancer. Palmer et al. (2020) delved into the risks of breast cancer in African American (AA) women associated with inherited mutations in breast cancer predisposition genes. Using germline DNA samples and drawing from 10 epidemiologic studies encompassing 5054 affected African American women and 4993 unaffected African American women, Palmer et al. (2020) sequenced mutations in 23 cancer predisposition genes using a QIAseq multiplex amplicon panel and found that pathogenic mutations could be identified in 10.3% of women with estrogen receptor (ER)-negative breast cancer, 5.2% of women with ER-positive breast cancer, and 2.3% of unaffected women. Mutations in BRCA1, BRCA2, and PALB2 were associated with an overall increased risk for breast cancer, while RAD51D mutations were observed specifically to be linked to higher risk of ER-negative disease. Other mutations the researchers found to be of interest were in CHEK2, ATM, ERCC3, FANCC, and RECQL. Thus, it was concluded that the study corroborated the use and “validity of current breast cancer testing panels for use in AA women” (Palmer et al., 2020).

A study using next generation sequencing (NGS) to identify BRCA mutations was performed by Lang et al. 4034 patients were screened (2991 breast cancer patients, 1043 healthy controls). BRCA mutations were found in 247 of the breast cancer patients or 8.3%. 13.9% (16/115) of the BRCA1 mutations were of the “c.5470_5477del” variation, and several clinical characteristics such as high KI67 index and high tumor grade were related to BRCA mutations, BRCA2 carriers were also found to have poorer disease-free survival among HER2 positive patients (Lang et al., 2017).

Tomao et al. (2019) investigated the ability of BRCA mutational status on predicting hematologic toxicity with platinum-based chemotherapy. 176 patients were included, with 58 BRCA mutation carriers (40 BRCA1, 18 BRCA2, 118 controls). The authors identified several differences in hematologic toxicity between the two groups; the BRCA positive group was observed to have significantly higher frequency in “thrombocytopenia (24% vs 5%), anemia (21% vs 7%; p = 0.006) and neutropenia (62% vs 27%)”. The authors also noted that granulocyte-colony stimulating growth factors injection (12% versus 1%,) and dose delay (19% versus 27%) were more likely in the BRCA positive group (odds ratio = 2.567 for granulocyte-colony stimulating growth factors injection and 3.860 for dose delay). Overall, the authors concluded that “germline BRCA 1/2 mutations are associated with a higher hematologic toxicity in patients with ovarian cancer who underwent platinum-based chemotherapy” (Tomao et al., 2019).

Yoo et al. (2020) conducted BRCA1/NGS for 262 hereditary breast and ovarian cancer (HBOC) syndrome patients, and the results were confirmed by using multiplex ligation-dependent probe amplification and direct Sanger sequencing. A multigene panel test was also performed on 120 patients who did not possess BRCA1/2 pathogenic variants but who met NCCN criteria for testing. The researchers reported that pathogenic variants in BRCA1/2 were detected in 30 HBOC patients (11.5%), and four out of the 120 patients possessed pathogenic variants of MSH2 PMS2, CHEK2 and PALB2, which were also detectable by multigene panel testing. The results suggested to the authors that “Multi-gene panel testing could be a significant screening tool for HBOC patients, especially for those with a family history of cancer” (Yoo et al., 2020).

BRCA testing has been demonstrated to be potentially beneficial even when the testing is unselected and is population based. Manchanda et al. (2020) examined the North London Ashkenazi-Jewish (AJ) population in a randomized controlled trial consisting of 1034 AJ women and men across two arms— one, a population-screening approach, and a second, a family history/clinical-criteria-based BRCA testing—to determine subsequent effects on psychological health and quality of life after providing genetic testing for three Jewish BRCA founder-mutations. Based on the results of the study, the researchers drew the conclusion that “Population-based AJ BRCA testing does not adversely affect longterm psychological wellbeing or quality-of-life, decreases anxiety and could identify up to 150% additional BRCA carriers” (Manchanda et al., 2020). However, these results on the anxiety and healthanxiety of this population may be contested, for validated questionnaires were used to measure the psychological wellbeing of the participants at baseline/1-year/2-year/3-year follow-ups. Moreover, the participants were recruited through self-referral, which may affect the internal validity of the trials.

The NCCN states that general hereditary cancer testing may be considered in the following scenario (with appropriate pre-test education and access to post-test management):

• An individual of Ashkenazi Jewish ancestry without additional risk factors. 
• Personal history of serious endometrial cancer.

The NCCN states that testing for high-penetrance breast cancer susceptibility genes may be considered in the following scenarios (with appropriate pre-test education and access to post-test management):

1. Personal history of breast cancer <60y not meeting any of the above criteria may approach a 2.5% probability of having a pathogenic/likely pathogenic variant, based on recent data. It is cautioned that many of those PVs will be in moderate penetrance genes, which are over-represented in older affected individuals. Access to an experienced genetic counseling team to discuss management options is particularly important in this setting.
2. Personal history of breast cancer diagnosed at any age with >1 close blood relative with intermediate-risk prostate cancer with intraductal/cribriform histology.
3. Individuals affected or unaffected with breast cancer who otherwise do not meet any of the above criteria but with a 2.5%-5% probability of BRCA 1/2 pathogenic variant/likely pathogenic variant based on prior probability models (e.g., Tyrer-Cuzick, BRCAPro, CanRisk).

The NCCN states that when testing for high-penetrance breast cancer susceptibility genes, there is “a low probability (<2.5%) that testing will have findings of documented high-penetrance genes in the following scenarios:

1. Female diagnosed with breast cancer at age >60 y, with no close relative with breast, ovarian, pancreatic, or prostate cancer 
2. Diagnosed with localized prostate cancer with Gleason Score <7 and no close relative with breast, ovarian, pancreatic, or prostate cancer (NCCN, 2024b).

The NCCN suggests that prior to genetic testing,

• “The probability of pathogenic or likely pathogenic variant detection associated with these criteria will vary based on family structure, which includes size of the family, age of the family members, early death, adoption, and number of male and female relatives. Individuals with unknown or limited family history/structure, such as fewer than 2 female first- or second-degree relatives having lived beyond age 45 in either lineage, may have an underestimated probability of familial P/LP variant detection. The estimated likelihood of P/LP variant detection may be low in families with many unaffected and/or male relatives.
• Patients who have received an allogeneic bone marrow transplant or with active or recent hematologic malignancies should not have molecular genetic testing via blood, saliva, or buccal samples (due to unreliable test results from contamination by donor DNA) until other technologies are available. If available, DNA should be extracted from a fibroblast culture. If this source of DNA is not possible, buccal samples can be considered, subject to the risk of donor DNA contamination or malignant cells from the hematologic malignancy.
• If more than one family member is affected with cancers highly associated with a particular inherited cancer susceptibility syndrome, consider initial testing of a family member with youngest age at diagnosis, bilateral disease, multiple primary cancers, or other cancers associated with the syndrome, or most closely related to the proband/patient. If there are no available family members with cancer that is a cardinal feature of the syndrome in question, consider testing first- or second-degree family members affected with other cancers thought to be related to the gene in question (eg, prostate or pancreas with BRCA1/2).
• “Testing for unaffected family members when no affected member is available should be considered. Significant limitations of interpreting test results should be discussed. 
• In children <18y, genetic testing is generally not recommended when results would not impact medical management.
• Likely pathogenic variants are usually clinically managed similarly to pathogenic variants, while patients with variants of uncertain significance (VUS) and likely benign variants should be managed based on the cancers present in the family. 
• Choice of multi-gene testing.” (NCCN, 2024b).

Furthermore, in the situation where the presence of a pathogenic or likely pathogenic variant is unknown, the NCCN recommends that “the testing of the unaffected individual (or of unaffected family members) should only be considered when no affected family member is available for testing. In such cases, the unaffected individual or unaffected close relative with the highest likelihood of testing positive for the pathogenic or likely pathogenic variant should be tested.” Though “A negative test result in such cases, however, is considered indeterminate and does not provide the same level of information as when there is known pathogenic or likely pathogenic variant in the family.” The NCCN also remarks that “testing multiple family members may be indicated” when testing unaffected individuals “(in the absence of having tested affected family members)” to aid in interpreting results (NCCN, 2024b). 

The NCCN also recommends assessing BRCA1/2 in all patients with recurrent or metastatic breast cancer to identify candidates for PARP inhibitor therapy (NCCN, 2024a).

Regarding BRCA in ovarian cancer, the NCCN recommends testing for BRCA1/2 mutations prior to initiating treatment for persistent/recurrent ovarian cancer since “germline and/or somatic BRCA1/2 status informs maintenance therapy.” The NCCN notes that BRCA testing may be done prior to this stage (NCCN, 2024c).

BRCA testing was also mentioned in guidelines for pancreatic adenocarcinoma. The NCCN recommends tumor/somatic gene profiling for those with “locally advanced/metastatic disease who are candidates for anti-cancer therapy to identify uncommon mutations,” including testing for mutations in BRAF, BRCA1/2, HER2, KRAS, and PALB2 genes, fusions in ALK, NRG1, NTRK, ROS1, FGFR2, RETgenes, microsatellite instability (MSI), mismatch repair deficiency (dMMR), or “tumor mutational burden (TMB) via an FDA-approved and/or validated next-generation sequencing, or NGS based assay.” (NCCN, 2024d).

The NCCN also published guidelines regarding BRCA in prostate cancer. Germline genetic testing, which should include BRCA1/2 among other genes, such as ATM, PALB2, and CHEK2 was recommended for initial patients with prostate cancer and any of the following: “a positive family history; high-risk, veryhigh-risk, regional, or metastatic prostate cancer, regardless of family history; Ashkenazi Jewish ancestry; [and] a personal history of breast cancer.” The NCCN also notes that “germline genetic testing should be considered in patients with a personal history of prostate cancer and 1) intermediate-risk prostate cancer and intraductal/cribriform histology” or 2) a personal history of exocrine pancreatic cancer, breast cancer, colorectal, gastric, melanoma, pancreatic cancer, upper tract urothelial cancer, glioblastoma, biliary tract cancer, and small intestinal cancer.” Moreover, the NCCN asserts that germline testing should include “MLH1, MSH2, MSH6, and PMS2 (for Lynch syndrome) and homologous recombination genes (BRCA1, BRCA2, ATM, PALB2, and CHEK2)”, urging that cancer predisposition next-generation sequencing be considered (NCCN, 2024e).

• Regarding somatic tumor testing in risk groups, “Tumor testing for somatic homologous recombination gene mutations (eg, BRCA1, BRCA2, ATM, PALB2, FANCA, RAD51D, CHEK2, CDK12) can be considered in patients with regional (N1) prostate cancer and is recommended for those with metastatic disease.”
• Tumor testing for MSI or dMMR can be considered in patients with regional or metastatic castration-naïve prostate cancer and is recommended in the metastatic castrate-resistant prostate cancer (CRPC) setting. 
• Tumor mutational burden (TMB) testing may be considered in patients with metastatic CRPC. 
• Multigene molecular testing can be considered for patients with low-, intermediate-, and highrisk prostate cancer and life expectancy ≥10 years. 
• The Decipher molecular assay is recommended to inform adjuvant treatment if adverse features are found post-radical prostatectomy and can be considered as part of counseling for risk stratification in patients with PSA resistance/recurrence after radical prostatectomy (category 2B)” (NCCN, 2023e).

The NCCN published information on TP53 as a pathogenic/likely pathogenic variant, noting that testing for Li-Fraumeni syndrome should occur when the individual is from a family with a known TP53 pathogenic/likely pathogenic variant. They specifically note that when this gene is “included as part of a multi-gene panel, an individual does not need to meet these testing criteria [for Li-Fraumeni syndrome]- if “testing criteria on other testing criteria pages are met” (NCCN, 2024b).

The U.S. Preventive Services Task Force (USPSTF)

In 2019, the USPSTF updated their 2014 recommendation (Moyer, 2014). In it, they state that “the USPSTF recommends that primary care clinicians assess women with a personal or family history of breast, ovarian, tubal, or peritoneal cancer or who have an ancestry associated with breast cancer susceptibility 1 and 2 (BRCA1/2) gene mutations with an appropriate brief familial risk assessment tool. Women with a positive result on the risk assessment tool should receive genetic counseling and, if indicated after counseling, genetic testing.” This recommendation is intended for women with a “personal or family history of breast, ovarian, tubal, or peritoneal cancer or an ancestry associated with BRCA1/2 gene mutation” (USPSTF, 2019).

Moreover, they do not recommend (i.e. issue a D recommendation) routine screening, genetic testing, or genetic counseling for women who have no family or personal history of breast cancer or whose ancestry or ethnicity is not associated with a higher risk for potentially pathogenic BRCA1 or BRCA2 gene mutations (USPSTF, 2019).

The American College of Obstetricians and Gynecologists (ACOG)

The ACOG released guidelines in 2019 for Hereditary Cancer Syndromes and Risk Assessments. The ACOG recommends:

• Evaluating a patient’s risk of hereditary breast and ovarian cancer syndrome should be a routine part of obstetric and gynecologic practice. Initial risk evaluation should include a personal medical history and family history. 
• Genetic testing is recommended when the results of a detailed risk assessment that is performed as part of genetic counseling suggest the presence of an inherited cancer syndrome for which specific genes have been identified and when the results of testing are likely to influence medical management.
• The two main genetic testing options for hereditary breast and ovarian cancer syndrome are BRCA mutation testing and multigene panel testing that includes both BRCA and other genetic mutations. Multigene panel testing may be useful when more than one gene may be associated with an inherited cancer syndrome or when a patient has a personal or family history that is consistent with an inherited cancer susceptibility, but single-gene testing has not identified a pathogenic variant (ACOG, 2019).

The American Society of Breast Surgeons

The American Society of Breast Surgeons have released guidelines on genetic testing for hereditary breast cancer. They are as follows: 

1. “Breast surgeons, genetic counselors, and other medical professionals knowledgeable in genetic testing can provide patient education and counseling and make recommendations to their patients regarding genetic testing and arrange testing”
2. “Genetic testing should be made available to all patients with a personal history of breast cancer. Recent data support that genetic testing should be offered to each patient with breast cancer (newly diagnosed or with a personal history). If genetic testing is performed, such testing should include BRCA1/BRCA2 and PALB2, with other genes as appropriate for the clinical scenario and family history. For patients with newly diagnosed breast cancer, identification of a mutation may impact local treatment” 
3. “Patients who had genetic testing previously may benefit from updated testing. Every patient being seen by a breast surgeon, who had genetic testing in the past and no pathogenic variant was identified, should be re-evaluated and updated testing considered. In particular, a patient who had negative germline BRCA1 and 2 testing, who is from a family with no pathogenic variants, should be considered for additional testing.1 Genetic testing performed prior to 2014 most likely would not have had PALB2 or other potentially relevant genes included and may not have included testing for large genomic rearrangements in BRCA1 or BRCA2” 
4. “Genetic testing should be made available to patients without a history of breast cancer who meet NCCN guidelines. Unaffected patients should be informed that testing an affected relative first, whenever possible, is more informative than undergoing testing themselves. When it is not feasible to test the affected relative first, then the unaffected family member should be considered for testing if they are interested, with careful pre-test counseling to explain the limited value of “uninformative negative” results. It is also reasonable to order a multi-gene panel if the family history is incomplete (i.e., a case of adoption, patient is uncertain of exact type of cancer affecting family members, among others) or other cancers are found in the family history, as described above” (Manahan et al., 2019).

American Society of Clinical Oncology (ASCO)

ASCO recommends germline genetic testing for BRCA1/2 for all women diagnosed with epithelial ovarian cancer. Somatic tumor testing for BRCA1/2 should be performed in women that do not carry a germline pathogenic or likely pathogenic variant (Konstantinopoulos et al., 2020).

ASCO also published a guideline regarding PARP inhibitors for ovarian cancer. In recommendation 2.2, they recommend the use of “Myriad myChoice CDx” to determine BRCA1/2 status for therapy decisions (Tew et al., 2020).

In 2024, ASCO published “Germline Testing in Patients with Breast Cancer: ASCO-Society of Surgical Oncology Guideline” with the following recommendations:

• “BRCA1/2 mutation testing should be offered to all newly diagnosed patients with breast cancer ≤65 years and select patients >65 years based on personal history, family history, ancestry, or eligibility for poly(ADP-ribose) polymerase (PARP) inhibitor therapy.” 
• “All patients with recurrent breast cancer who are candidates for PARP inhibitor therapy should be offered BRCA1/2 testing, regardless of family history. BRCA1/2 testing should be offered to women who develop a second primary cancer in the ipsilateral or contralateral breast.” 
• “For patients with prior history of breast cancer and without active disease, testing should be offered to patients diagnosed ≤65 years and selectively in patients diagnosed after 65 years, if it will inform personal and family risk.” 
• “Testing for high-penetrance cancer susceptibility genes beyond BRCA1/2 should be offered to those with supportive family histories; testing for moderate-penetrance genes may be offered if necessary to inform personal and family cancer risk.”
• “Patients should be provided enough pretest information for informed consent; those with pathogenic variants should receive individualized post-test counseling. Variants of uncertain significance should not impact management, and patients with such variants should be followed for reclassification.” 
• “Referral to providers experienced in clinical cancer genetics may help facilitate patient selection and interpretation of expanded testing, and provide counseling of individuals without pathogenic germline variants but with significant family history” (Bedrosian et al., 2024).

National Institute for Health and Care Excellence

NICE updated their guidelines on familial breast cancer in 2019. In it, they maintain their BRCA-related recommendations from 2013, which are as follows:

“Offer genetic testing in specialist genetic clinics to a relative with a personal history of breast and/or ovarian cancer if that relative has a combined BRCA1 and BRCA2 mutation carrier probability of 10% or more.”

“Offer genetic testing in specialist genetic clinics to a person with no personal history of breast or ovarian cancer if their combined BRCA1 and BRCA2 mutation carrier probability is 10% or more and an affected relative is unavailable for testing.”

“Offer genetic testing in specialist genetic clinics to a person with breast or ovarian cancer if their combined BRCA1 and BRCA2 mutation carrier probability is 10% or more” (NICE, 2019).

European Expert Group

A group of 19 experts in BRCA testing were convened to publish this set of guidelines. These experts came from all across Europe and included occupations such as clinical or medical geneticists (32%), oncologists (37%) and gynecologists (26%).

The guidelines state that with the rise of next-generation sequencing, hotspot testing instead of complete sequencing is “not acceptable”, albeit noting a possible exception of founder mutations representing >99% of pathogenic variants in a specific area.

A majority of experts (60%) voted that BRCA testing should be offered to all patients with metastatic breast cancer (Singer et al., 2019).

In 2021, the group published guidance on BRCA and HRR deficiency testing for recently diagnosed patients with ovarian cancer. Consensus statements pertaining to BRCA1/2 include (not an all-inclusive list):

1. “Tumor BRCA1/2 testing should be carried out at primary diagnosis. 
2. Tumor BRCA1/2 testing should be carried out at disease recurrence (if not carried out earlier) 
3. Germline and/or tumor BRCA testing should be used (in either order) to determine BRCA status at primary diagnosis” (Vergote et al., 2022).

State and Federal Regulations, as applicable

Food and Drug Administration (FDA)

The Center for Devices and Radiological Health of the Food and Drug Administration (FDA, 2018) granted premarket approval on January 12, 2018 to BRACAnalysis CDx® an in vitro diagnostic device intended for the qualitative detection and classification of variants in the protein coding regions and intron/exon boundaries of the BRCA1 and BRCA2 genes using genomic DNA obtained from whole blood specimens collected in EDTA. Single nucleotide variants and small insertions and deletions (indels) are identified by polymerase chain reaction (PCR) and Sanger sequencing. Large deletions and duplications in BRCA1 and BRCA2 are detected using multiplex PCR. Another FDA-approved device is the “FoundationFocus CDxBRCA”, which is a “is a next generation sequencing based in vitro diagnostic device for qualitative detection of BRCA1 and BRCA2 alterations in formalin-fixed paraffinembedded (FFPE) ovarian tumor tissue”. This test is intended to be used “as an aid in identifying ovarian cancer patients for whom treatment with Rubraca (rucaparib) is being considered” (FDA, 2016). A more recent FDA-approved device comes out of Myriad Genetics, Inc., the myChoice HRD CDx, which was approved on October 23, 2019. This test is a “next generation sequencing-based in vitro diagnostic test that assesses the qualitative detection and classification of single nucleotide variants, insertions and deletions, and large rearrangement variants in protein coding regions and intron/exon boundaries of the BRCA1 and BRCA2 genes and the determination of Genomic Instability Score (GIS)” based off tumor tissue specimens.

Many labs have developed specific tests that they must validate and perform in house. These laboratorydeveloped tests (LDTs) are regulated by the Centers for Medicare and Medicaid (CMS) as highcomplexity tests under the Clinical Laboratory Improvement Amendments of 1988 (CLIA ’88). As an LDT, the U. S. Food and Drug Administration has not approved or cleared this test; however, FDA clearance or approval is not currently required for clinical use.
