SUMMER: an integrated nanopore sequencing pipeline for variants detection and clinical annotation on the human genome

Long-read sequencing has emerged as a transformative technology in recent years, offering significant potential for the molecular diagnosis of unresolved genetic disorders. Despite its promise, the comprehensive detection and clinical annotation of genomic variants remain intricate and technically demanding. We present SUMMER, an integrated and structured workflow specifically designed to process raw Nanopore sequencing reads. SUMMER facilitates an in-depth analysis of multiple variant types, including SNV, SV, short tandem repeat and mobile element insertion. For clinical applications, SUMMER employs SvAnna to prioritize SV candidates based on phenotype relevance and utilizes Straglr to provide reference distributions of non-pathogenic unit counts for 55 known pathogenic short tandem repeats. By addressing critical challenges in variant detection and annotation, SUMMER seeks to advance the clinical utility of long-read sequencing in diagnostic genomics.
