Oculopharyngeal muscular dystrophy (OPMD) is a late-onset myopathy caused by (GCN) expansions in the polyalanine binding protein nuclear 1 gene (PABPN1) located on chromosome 14q11. This study reports a case of an incomplete clinical characteristics of OPMD with heterozygous (GCN)11 expansion. A fifty-nine-year-old Korean woman was suffering from non-progressive dysarthria, dysphagia for five years. Neurologic findings were unremarkable except for tongue atrophy and mild ptosis. A genetic screening confirmed heterozygous (GCN)11 expansion in the PABPN1 gene.
