Introduction: Long‐read whole genome sequencing like Oxford Nanopore Technology, is increasingly being introduced in clinical settings. With its ability to simultaneously call sequence variation and DNA modifications including 5‐methylcytosine, nanopore is a promising technology to improve diagnostics of imprinting disorders. Methods: Currently, no tools to analyze DNA methylation patterns at known clinically relevant imprinted regions are available. Here we present NanoImprint, which generates an easily interpretable report, based on long‐read nanopore sequencing, to use for identifying clinical relevant abnormalities in methylation levels at 14 imprinted regions and diagnosis of common imprinting disorders. Results and conclusion: NanoImprint outputs a summarizing table and visualization plots displays methylation frequency (%) and chromosomal positions for all regions, with phased data color‐coded for the two alleles. We demonstrate the utility of NanoImprint using three imprinting disorder samples from patients with Beckwith‐Wiedemann syndrome (BWS), Angelman syndrome (AS) and Prader‐Willi syndrome (PWS). NanoImprint script is available from https://github.com/carolinehey/NanoImprint. [ABSTRACT FROM AUTHOR] |
