Personalis ImmunogenomicsID and NeoantigenID

Personalis has launched ImmunogenomicsID, which combines DNA and RNA sequencing data to generate an immunogenomic profile of a tumor and its microenvironment. The product is designed to help identify biomarkers and signatures that can impact patient response to cancer immunotherapies. It is a new component and extension of the company's existing ACE ImmunoID Platform, which combines genome-scale sequencing with data analytics for broad tumor immunogenomic characterization.  

The company also announced the latest release of NeoantigenID, a component of the ACE ImmunoID platform. ACE ImmunoID, which uses Personalis' patented ACE technology, combines augmented exome and transcriptome sequencing with analytics to enable broad tumor immunogenomic characterization. This newest release of NeoantigenID not only identifies candidate neoantigens derived from single nucleotide variants, but now also includes putative neoantigens derived from insertion and deletion mutations and gene fusions, for both MHC Class I and Class II, the company said. The new analytics integrate DNA and RNA sequencing data to calculate neoantigen load, expression of genes, and expression of variants, while incorporating phasing information to improve the accuracy of neoantigen prediction.
