Acta Neuropathologica Communications volume 8Article number: Cite this article. Metrics details. Oculopharyngodistal myopathy OPDM is a rare hereditary muscle disease characterized by progressive distal limb weakness, opdm, ptosis, ophthalmoplegia, bulbar muscle weakness and opdm vacuoles on muscle biopsy. Intra-myonuclear inclusions were evaluated using immunohistochemistry and electron microscopy EM, opdm.

Many rare diseases have limited information. Currently, GARD aims to provide the following information for this disease:. Symptoms related to this disease may affect different systems of the body. Use the 'Filter and Sort' function to learn more about which body system s are affected by this disease and their associated symptom s. An anomaly of a muscle that is innervated by the facial nerve the seventh cranial nerve. It is possible for a biological parent to pass down genetic mutations that cause or increase the chances of getting this disease to their child. This is known as inheritance.

Progressive ptosis, which may be asymmetric, is an early sign. Extraocular palsy occurs as well. The mean age of onset of this progressive disease is 22 years. Pharyngeal and distal limb muscles seem to be primarily involved. Weakness in masseter, facial, and bulbar muscles have been observed but no muscle group seems to be spared. Atrophy of facial muscles is common and may be pronounced. There is considerable variability in expression, particularly in the degree of limb weakness which often appears by the fifth decade. Swallowing difficulties can be severe. Respiratory weakness may be evident relatively early, even while patients are still ambulatory. Loss of ambulation most commonly occurs by the third or fourth decade after the onset of first symptoms. Serum creatine kinase levels are mildly elevated and histologic changes show chronic myopathic changes with rimmed vacuole formation. No changes have been found in the central or peripheral nervous system. The causative mutation has not been identified but mutations causing other forms of hereditary myopathy have been ruled out. Most families are consistent with autosomal dominant inheritance but the pattern in at least one family has suggested a recessive pattern indicating genetic heterogeneity.

Oculopharyngodistal myopathy OPDM and oculopharyngeal muscular dystrophy OPMD are similar and even believed to be indistinguishable in terms of their myopathological features. The online version contains supplementary material available at Oculopharyngodistal myopathy OPDM is characterized clinically by progressive ptosis, ophthalmoplegia, bulbar muscle involvement, and limb muscle weakness that is predominantly distal and pathologically by the presence of rimmed vacuoles [ 11 ]. However, this muscle disease is caused by an alanine expansion mutation in the poly-adenine-binding protein nuclear 1 PABPN1 gene [ 1 ]. It is also clinically characterized by oculopharyngeal muscle involvement and rimmed vacuolar pathology, but the associated limb muscle weakness is typically proximal, rather than distal [ 14 , 16 ]. The histopathology of these two diseases is quite similar and indistinguishable.
