However, there is a paucity of tools available to investigate variants in sORF regions of the genome. Here we investigate the performance of commonly used tools for variant calling and variant prioritisation in these regions, and present a framework for optimising these processes. First, the performance of four widely used germline variant calling algorithms is systematically compared. Haplotype Caller is found to perform best across the whole genome, but FreeBayes is shown to produce the most accurate variant set in sORF regions. An accurate set of variants is found by taking the intersection of called variants. The potential deleteriousness of each variant is then predicted using a pathogenicity scoring algorithm developed here, called sORF-c. This algorithm uses supervised machine-learning to predict the pathogenicity of each variant, based on a holistic range of functional, conservation-based and region-based scores defined for each variant. By training on a dataset of over 130,000 variants, sORF-c outperforms other comparable pathogenicity scoring algorithms on a test set of variants in sORF regions of the human genome.AUPRCArea under the precision-recall curveBEDBrowser Extensible DataCADDCombined annotation-dependent depletionDANNDeleterious annotation of genetic variants using neural networksEPOEnredo, Pecan, Ortheus pipelineGATKGenome analysis toolkitGIABGenome in a bottleHGMDHuman gene mutation databaseIndelsInsertions and deletionsMSMass spectrometryORFOpen reading frameRFRandom ForestsROCReceiver Operating CharacteristicsSEPsORF encoded peptidesklearnScikit-learn packageSNVsSingle nucleotide variantssORFShort open-reading frameTFTranscription factorTSSTranscription start siteVCFVariant Call Format file %U https://www.biorxiv.org/content/biorxiv/early/2017/05/03/133645.full.pdf
