Understanding correlations between mutations and therapeutic approaches

NGS methods enable efficient identification of neoantigens

Neoantigen Analysis

Next-generation sequencing (NGS) can help researchers identify neoantigens, study innovative therapies to boost the immune response, and understand how genetic variation can influence their efficacy. Characterization of expressed neoantigens has also contributed to development of vaccines and cell-based therapeutic methods.

TMB Analysis with Targeted NGS

Comprehensive coverage of cancer-related variants and improved filtering algorithms enable robust analysis of tumor mutational burden as well as microsatellite instability.

Read Application Note

While the clinical utility of tumor mutational burden is being defined, continuing efforts to standardize TMB analysis are ongoing.

Recent studies have demonstrated that tumor mutational burden can be effectively estimated using targeted sequencing panels.5-6 Specific features are recommended to enhance accuracy in TMB scoring, such as a minimum size of 1.5 Mb genomic content, and algorithms to filter variants that are unlikely to contribute to immunogenicity. 5-6

Mutations in protein coding genes of cancer cells are a source of potential neoantigens that the immune system can target. NGS has enabled the predictive selection of novel tumor antigens that can be applied to elicit a tumor-specific response.

DNA and/or RNA is efficiently characterized by exome sequencing and/or transcriptome sequencing. Improved bioinformatics tools aid neoantigen selection by predicting the presentation of mutant peptides for recognition by the immune system.
