Patent number: 11610648Abstract: The method includes compressing numbers of reads data for targeted genes of a gene expression assay performed on a test sample. The targeted genes are organized into categories. Each category represents a functional context associated with the targeted genes in that category. The numbers of reads corresponding to targeted genes each category is compressed to form a compressed value for the category. The compressed value is compared to a baseline value for the category to determine an enrichment or a loss of a signature corresponding to the functional context of the category. The method may include analyzing information from multiple assays performed on the test sample, assigning a score value to each assay result and predicting a response to immune-oncology treatment based on the assigned scores.Type: GrantFiled: April 17, 2020Date of Patent: March 21, 2023Assignee: Life Technologies CorporationInventors: Fiona Hyland, Asha Kamat, Timothy Looney
