摘要: Insertions and deletions (indels) are a major class of genomic variation associated with human disease. Indels primarily detected from DNA sequencing (DNA-seq) data but their transcriptional consequences remain unexplored due to challenges in discriminating medium-sized large indels splicing events RNA-seq data. Here, we developed transIndel, splice-aware algorithm that parses the chimeric alignments predicted by short read aligner reconstructs mid-sized insertions based on linear split reads DNA-seq or TransIndel exhibits competitive superior performance over eight state-of-the-art indel detection tools benchmarks using both synthetic real Additionally, applied transIndel datasets 333 primary prostate cancer patients The Cancer Genome Atlas (TCGA) 59 metastatic AACR-PCF Stand-Up- To-Cancer (SU2C) studies. enhanced taxonomy DNA- RNA-level alterations identifying recurrent FOXA1 as well exitron genes implicated disease progression.
