Breast & Ovarian Cancer Syndrome (BRCA1/BRCA2) - Clinical Genetic Testing
Clinical genetic testing for mutations in the BRCA1 and BRCA2 genes may be available for people who are considered at risk for hereditary breast and ovarian cancer syndrome. Males with mutations in the BRCA1 and BRCA2 genes may also be at increased risk to develop breast cancer as well as other associated cancers.
This testing is for medical, clinical purposes.
This testing is available online at the Direct-to-Consumer Genetic Testing providers listed below.
This testing is also available through offline genetic testing providers if indicated by further evaluation and consultation with a trained genetic professional. Use the zip code search box to find a trained genetic professional in your area.

Breast Cancer - Clinical Predisposition Testing
Most cases of cancer are sporadic. Families in which there are multiple affected, close members with the same cancer or associated cancers are more likely to have a stronger genetic component.
Clinical genetic testing for the genetic conditions, mutations, and hereditary cancer syndromes associated with predisposition to breast cancer is for medical, clinical purposes.
This testing may be available through offline genetic testing providers if indicated by further evaluation and consultation with a trained genetic professional. Use the zip code search box to find a trained genetic professional in your area.
Breast Cancer (as part of Whole Genome Scan)
Informational genetic testing for breast cancer susceptibility may also be available as part of a whole genome scan.
Whole genome scanning looks for SNPs that are present throughout the entire genome that have been linked to susceptibility to a number of different health conditions and physical traits. A SNP is a genetic change in which one "letter" of DNA differs from the usual "letter" at that point in the DNA sequence. The number of conditions, traits, and SNPs tested for varies by provider.
Whole genome scanning is for informational purposes only and is not a medical (clinical) genetic test. As such, other types of genetic testing may be more informative.
This testing is available online through the Direct-to-Consumer Genetic Testing providers listed below. A consultation with a trained genetic professional may be useful.

Tamoxifen 2D6 - Drug Response Testing
Genetic testing looks for variations that have been proposed to influence the way the body metabolizes tamoxifen. Genetic testing may help doctors prescribe more effective and safer medications. The variations and genes tested for varies by provider.
This testing is for medical, clinical purposes.
This testing is available online at the Direct to Consumer Genetic Testing providers listed below.
This testing is also available through offline genetic testing providers if indicated by further evaluation and consultation with a trained genetic professional. Use the zip code search box to find a trained genetic professional in your area.

Breast & Ovarian Cancer Syndrome (BRCA1/BRCA2) - Selected Mutations (as part of Whole Genome Scan)
BRCA1/BRCA2 testing by whole genome scanning looks for selected mutations in these genes. Depending on the methodology used, whole genome scanning is typically not as accurate as conventional molecular genetic testing methods.
As such, individuals who have a personal history of breast and/or ovarian cancer, have a family history of breast and/or ovarian cancer, or have a family history of a known BRCA1/BRCA2 mutation may be better candidates for conventional molecular testing methods. Test results should be discussed with a genetic professional.

Breast Cancer - Informational Susceptibility Testing
SNP testing for susceptibility to breast cancer looks for a single SNP or multiple SNPs that have been linked to this trait. A SNP is a genetic change in which one "letter" of DNA differs from the usual "letter" at that point in the DNA sequence. The number of SNPs tested for varies by provider. At this point, this testing is considered for informational purposes only and is not a medical (clinical) genetic test.
SNP testing is available online through the Direct-to-Consumer Genetic Testing providers listed below. A consultation with a trained genetic professional may be useful.
