Test Catalog

Test Name

Test ID: BRST4    
Hereditary Breast Cancer 4 Gene Panel

Useful For Suggests clinical disorders or settings where the test may be helpful

Establishing a hereditary susceptibility to cancer


Evaluation of families with a history suggestive of a hereditary breast cancer syndrome in which a BRCA1 or BRCA2 gene mutation is not identified


Identification of familial TP53, PTEN, CDH1, or STK11 mutation to allow for predictive testing in family members

Genetics Test Information Provides information that may help with selection of the correct genetic test or proper submission of the test request

This test includes next-generation sequencing and array comparative genomic hybridization (aCGH) to evaluate for mutations and large deletions/duplications in the TP53, PTEN (including the promoter), CDH1, and STK11 genes. Sanger sequencing may also be performed to confirm detected variants.


Prior Authorization is available for this assay; see Special Instructions.
