ColoSeq™ - Polyposis Panel (APC and MUTYH Only)

Questions: 1-800-256-0893


ColoSeq Polyposis Panel

ColoSeq™ Polyposis is a genetic test for hereditary adenomatous polyposis syndromes that uses next-generation sequencing to detect mutations APC and MUTYH. Mutations in APC are associated with familial adenomatous polyposis (FAP), an autosomal dominant condition that can be associated with markedly elevated colon cancer risk. Mutations in MUTYH are associated with an autosomal recessive adenomatous polyposis syndrome. The assay sequences all exons, introns, and flanking sequences of APC and MUTYH. Large deletions and duplications are also detected by the assay and reported. For the full ColoSeq™ Lynch and Polyposis Panel click here.

ColoSeq - Lynch and Polyposis Panel (comprehensive colon cancer risk panel)

For information on ColoSeq™ Lynch and Polyposis Panel see ColoSeq - Lynch and Polyposis


This assay sequences all exons and flanking intronic sequences of APC and MUTYH. A total of 100 kb 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 Pritchard et al. 2012 (1). Large deletions and duplications are detected using methods described by Nord et al. 2011 (2).
