ABSTRACT
Oculopharyngeal muscular dystrophy (OPMD) is typically inherited in an autosomal dominant fashion and is characterized by late onset proximal muscle weakness, ptosis and difficulty swallowing. It is caused by expansion mutations in the PABPN1 gene on chromosome 14q11. There is also a rare recessive form of the disease caused by homozygosity of a very small expansion mutation in the same gene. Hereditary neuropathy with liability to pressure palsies (HNPP) is an autosomal dominant disorder characterized by recurrent peripheral monofocal neuropathies. In this report a patient with both recessive OPMD and HNPP is described. The presence of two genetically unlinked neurological diagnoses in the same individual is a rare event and may have delayed the diagnoses.
