Hereditary High Risk Breast Cancer Panel
Test Information: The High Risk Hereditary Breast Cancer Panel uses next-generation sequencing and deletion/duplication analysis to simultaneously analyze selected genes associated with an increased risk of breast cancer. Hereditary breast cancer accounts for approximately 10% of breast cancer cases. Approximately 25-50% of hereditary breast cancer cases have mutations in the BRCA1/2 genes. Additional high-risk breast cancer genes include CDH1, PALB2, PTEN, STK11 and TP53. In general, the test is used when a patient's medical history and family history findings strongly suggest that there is an underlying genetic etiology of breast cancer.
Test Details
Test Code: 9155
Special Notes: The panel includes exon by exon sequencing, indels and gross copy number analyses of 7 genes that associated with high risk of breast cancer.
Certain exons with no known gross deletion/duplication mutations may not be covered by deletion/duplication analysis.
A Hereditary Breast Cancer Panel (Test code: 9170) is also available, which is more comprehensive and includes 20 genes associated with breast/ovarian cancer.

BRCA1 and BRCA2 gene sequencing and deletion/duplication analysis are performed via next generation sequencing by Counsyl.
