ABSTRACT
HNRNPA1 variants are known to cause degenerative motoneuron and muscle diseases which manifests in middle age or later. We report on a girl with early childhood onset, rapidly progressive generalized myopathy including ultrastructural findings in line with a proteinopathy. Proteomics of patient-derived muscle and combined screening of genomic data for copy number variations identified a HNRNPA1 de novo intragenic deletion as causative for the phenotype. Our report expands the spectrum of HNRNPA1-related diseases towards early-childhood onset and adds HNRNPA1 to the growing list of ALS and myopathy genes for which certain mutations may cause severe pediatric phenotypes.
