Description
UW-OncoPlex is a multiplexed mutation assay for tumor tissue that assesses mutations in 262 genes related to cancer treatment, prognosis, or diagnosis. The genes are sequenced on an Illumina instrument to detect single nucleotide variants, insertions, deletions, gene amplifications, and selected translocations. Microsatellite instability (MSI) status is reported for colorectal cancer cases. This test is designed to detect somatic mutations in cancer, and is not designed to detect germline (heritable) mutations.

Methodology
Method: UW-OncoPlex is a multiplexed gene sequencing panel that detects mutations in tumor tissue in 262 cancer-related genes (listed in the methods below). The panel includes genes related to cancer treatment, prognosis, and diagnosis. The test uses next-generation "deep" sequencing to detect most classes of mutations, including single nucleotide variants, small insertions and deletions (indels), gene amplifications, and selected gene-fusions. In addition, microsatellite instability status is reported for colorectal cancers.
Analytical Volume: 3 mL for Whole Blood or Bone Marrow, 3 mcg of Purified DNA
