BROCA/ColoSeq™ - Single Gene
BROCA/ColoSeq Single Gene
This test is for a single gene selected from the BROCA or ColoSeq™ Lynch and Polyposis panels, which must be written in on the requisition. For the full BROCA Cancer Risk Panel click here and for full ColoSeq™ Lynch and Polyposis Panel click here. This test uses next-generation sequencing to detect most mutations. The assay completely sequences all exons, introns, and flanking regions of these gene AND detects large deletions, duplications and mosaicism.
This assay sequences all exons and flanking intronic sequences of one user-selected gene from the BROCA or ColoSeq™ Cancer Risk Panels. DNA is sequenced at an average coverage of 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 Pritchard et al. 2012 (1). Large deletions and duplications are detected using methods described by Nord et al. 2011 (2).
