This assay is a multiplexed gene sequencing panel designed to detect mutations associated with hematologic myeloid and lymphoid disorders. Purified genomic DNA is enzymatically sheared and targeted sequences are isolated by hybrid capture probes and sequenced by using an Illumina NGS platform.
This assay will not detect variants if present in only a small proportion of cells in the sample. If indicated, additional testing for FLT3-ITD and CEBPA mutations for new evaluation of acute myeloid leukemia should be separately ordered.
This assay is not intended for post-treatment disease monitoring nor comprehensive germline evaluation and is not validated to detect all classes of genomic alterations, such as large structural events including fusions and copy alterations.
If indicated, separate panel-based testing can be performed for myeloid-focused genes (HCAPMY) or lymphoid-focused genes (HCAPL). This assay is focused on hematologic disorders; for solid tumor testing, consider UW-Oncoplex testing.
