Background:
Features included:
- Tumor mutation burden estimate (TMB)
- Identification of microsatellite instability (MSI)
- Genes related to resistance to immune checkpoint inhibitor treatment (HLA genes, B2M, JAK1, JAK2, IFNGR1, IFGR2)
The GeneTrails® Solid Tumor Panel (STP) is a next-generation sequencing (NGS) test used to screen for clinically informative gene alterations that are important in making therapeutic decisions, including SNVs, in/dels, and copy number alterations. The test can detect microsatellite instability and can provide an estimate of tumor mutation burden (TMB). The STP is intended for the analysis of solid tumors from patients with clinically advanced disease (stage III or IV). It covers genes that are informative for the use of FDA-approved therapies in non-small cell lung cancer (EGFR, BRAF, ALK, ROS1), colorectal cancer (KRAS, NRAS, BRAF), breast cancer (PIK3CA), and bladder cancer (FGFR2/3).1-6
This panel will be reflexed to the GeneTrails Gene Fusion Panel when appropriate to screen for actionable kinase gene fusions if the Solid Tumor Panel results are negative.

Methodology:
The Solid Tumor Panel is performed on DNA extracted from formalin-fixed, paraffin-embedded (FFPE) tumor tissue using next-generation sequencing. The NGS library preparation is based on custom QiaSeq chemistry (Qiagen) that includes unique molecular indices for the assessment of library complexity. Sequencing is performed on Illumina NextSeq500/550 instruments and the data are analyzed through custom bioinformatics pipelines. The DNA library is generated by 9,229 custom-designed primer extension assays covering 613,343 base pairs across 225 cancer-related genes (whole exons of 199 genes, hotspot regions of 26 genes). This panel is routinely sequenced to an average read depth of ~2,000, providing high sensitivity for SNVs, in/dels and copy number alterations. Variants are identified using both FreeBayes and MuTect2 algorithms in a custom sequencing analysis pipeline. Included in the panel are 227 short repeats that are used to assess microsatellite instability. TMB is estimated by determining the number of likely somatic mutations and normalizing this to mutations per megabase of sequence.
