When developing effective personalized immunotherapies, such as cancer vaccines, a pivotal factor lies in uncovering tumor neoantigens that can serve as crucial therapeutic targets. Traditionally, neoantigen discovery heavily relied on short-read sequencing technology, with a predominant focus on neoantigens resulting from single-nucleotide variants (SNVs). However, recent advancements have unveiled the…

This is due to the fact that the very reference genomes that we use for re-alignment are themselves based on individuals who carry rare risk alleles. Thus, when we call variants against these genomes, we are, at many loci, comparing against rare disease risk alleles. As the best/worst example (depending…
