BROCA - Cancer Risk Panel
- BROCA is useful for the evaluation of patients with a suspected hereditary cancer predisposition, with a focus on syndromes that include breast or ovarian cancer as one of the cancer types. Depending on the causative gene involved, these cancers may co-occur with other cancer types (such as colorectal, endometrial, pancreatic, endocrine, or melanoma).
- The test uses next-generation sequencing to detect mutations in the genes listed in the table below.
- The assay completely sequences all exons and flanking introns of these genes AND detects large deletions, duplications, and mosaicism.
Testing can be ordered for a single gene (next generation sequencing) or subset of genes on the BROCA panel. Custom BROCA can be ordered by specifying genes for which testing is requested on the requisition; pricing is the same as full BROCA Cancer Risk Panel.
For patients with a suspected hereditary colon cancer syndrome see ColoSeq Lynch and Polyposis panel.
For information about how University of Washington Department of Laboratory Medicine reports variants, see Variant Policy.
For additional testing information, see Points to Consider, patient information sheet.

This assay sequences all exons and flanking intronic sequences of AKT1, APC, ATM, ATR, BAP1, BARD1, BMPR1A, BRCA1, BRCA2, BRIP1, CDH1, CDK4, CDKN2A, CHEK1, CHEK2, CTNNA1, FAM175A (Abraxas), GALNT12, GEN1, GREM1, HOXB13, MEN1, MLH1, MRE11A, MSH2 (+EPCAM), MSH6, MUTYH, NBN, PALB2, PIK3CA, PMS2, POLD1, POLE, PRSS1, PTEN, RAD51B, RAD51C, RAD51D, RET, SDHB, SDHC, SDHD, SLX4, SMAD4, STK11, TP53, VHL, and XRCC2. A total of 1.1 Mb (1.1 Million base pairs) are sequenced and the average coverage ranges from 320 to >1,000 sequencing reads per bp. Genomic regions are captured using biotinylated RNA oliognucleotides (SureSelect), prepared in paired-end libraries with ~200 bp insert size, and sequenced on an Illumina HiSeq2000 instrument with 100 bp read lengths, in a modification of a procedure described by Walsh et al. 2010 (1) and 2011 (2). Large deletions and duplications are detected using methods described by Nord et al. 2011 (3).
