Single Gene Analysis by next-generation sequencing
This test allows analysis of any single gene on the BROCA Cancer Risk, ColoSeq™ Lynch and Polyposis, or EpiPlex Epileptic Encephalopathy panels. To order, select Single Gene testing and write the gene in the space provided in the requisition. For the full BROCA Cancer Risk Panel click here, ColoSeq™ Lynch and Polyposis Panel click here, and EpiPlex Epileptic Encephalopathy 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. For information about how University of Washington Department of Laboratory Medicine reports variants, see Variant Policy.
This assay sequences all exons and flanking intronic sequences of one user-selected gene from the BROCA, ColoSeq™, EpiPlex 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).
