A deep learning model embedded framework to distinguish DNA and RNA mutations directly from RNA-seq

Abstract

AbstractWe develop a stepwise computational framework, called DEMINING, to directlydetectexpressed DNA and RNAmutations in RNA deep sequencingdata. DEMINING incorporates a deep learning model named DeepDDR, which facilitates the separation of expressed DNA mutations from RNA mutations after RNA-seq read mapping and pileup. When applied in RNA-seq of acute myeloid leukemia patients, DEMINING uncovered previously-underappreciated DNA and RNA mutations, some associated with the upregulated expression of host genes or the production of neoantigens. Finally, we demonstrate that DEMINING could precisely classify DNA and RNA mutations in RNA-seq data from non-primate species through the utilization of transfer learning.
