Two different PABPN1 expanded alleles in a Mexican population with oculopharyngeal muscular dystrophy arising from independent founder effects.


BACKGROUND Oculopharyngeal muscular dystrophy (OPMD) is a late onset hereditary myopathy of autosomal dominant transmission characterised by ptosis, dysphagia and limb weakness. The disease is caused by short heterozygous expansions of a (GCN)(10) triplet located in the first exon of the PABPN1 gene at chromosome 14q11.1. Most affected individuals from… (More)
