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).

Requisition Form

  1. Fill out a Clinical Lab Request - Genetics - available at UWMC Genetics Requisition

  2. Under "Check Test Requested," check: "BROCA - Cancer Risk Panel"
  3. To order a subset of genes on the BROCA panel, check: "BROCA - Cancer Risk Panel" and note the genes for which testing is being ordered. Custom BROCA pricing is the same as full BROCA panel. For single gene next-generation sequencing, see Single Gene analysis.

Specimen Requirements and Handling

10 mL whole blood in lavender top (EDTA) tube. ACD is also acceptable.

Turnaround Time

8 weeks (56 days)
