PABPN1 pathogenic expansion in the UK Biobank: reframing genetic prevalence of oculopharyngeal muscular dystrophy.
BACKGROUND Oculopharyngeal muscular dystrophy (OPMD) is a rare, late-onset, mostly autosomal dominant muscular dystrophy caused by a trinucleotide GCN repeat expansion in PABPN1. OPMD affects approximately 1:100 000 individuals in Europe, with substantially higher prevalence in specific founder populations. Pathogenic...
