Targeted nanopore long-read sequencing panel for the molecular diagnosis of intronic expansion in familial adult myoclonic epilepsy

This targeted long-read panel enabled the first clinical molecular diagnosis of FAME using a comprehensive assay, yielding allele-resolved characterization of the pathogenic repeat and its motif composition. With further validation, this approach may serve as a clinically practical tool for reliable detection of FAME1 and for broader screening of other FAME subtypes, potentially reducing reliance on prolonged clinical observation or specialized electrophysiological testing.
