gene panel testing
Targeted sequencing of a predefined set of cancer-relevant genes to detect clinically significant alterations.
Full Definition
Gene panel testing is a focused molecular diagnostic approach that analyzes a curated subset of genes known to be relevant for cancer diagnosis, prognosis, or treatment selection. Unlike whole exome or genome sequencing, panel testing concentrates on genes with established clinical significance, typically ranging from dozens to hundreds of targets. Panels may be designed for specific cancer types, therapeutic classes, or clinical applications such as hereditary cancer predisposition. This approach balances comprehensive coverage of relevant genes with practical considerations including turnaround time, cost, and data interpretation complexity. Modern cancer gene panels often include hotspot regions, full gene coverage for tumor suppressors, and copy number analysis.
