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.

Brain MR examinations were available in five patients Fig.

Oculopharyngodistal myopathy OPDM is a rare hereditary muscle disease characterized by progressive distal limb weakness, ptosis, ophthalmoplegia, bulbar muscle weakness and rimmed vacuoles on muscle biopsy. Intra-myonuclear inclusions were evaluated using immunohistochemistry and electron microscopy EM. All seven patients clinically demonstrated ptosis, ophthalmoplegia, dysarthria and muscle weakness; they myopathologically had intra-myonuclear inclusions stained with anti-poly-ubiquitinated proteins, anti-SUMO1 and anti-p62 antibodies, which were diagnostic of NIID typically on skin biopsy , in addition to rimmed vacuoles.

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 ].

This data is used to determine if a newborn screening is recommended federally or by the state. Six patients had regenerating fibers, and one patient had no necrotic or regenerating fibers Fig. Article Title:. Ethics declarations Ethics approval and consent to participate All patients provided informed consent for using their samples for research after the diagnosis. Diagnostically, the presence of intranuclear inclusions stained with anti-poly-ubiquitinated protein, anti-SUMO1, and anti-p62 antibodies in the skin and other organs is pathognomonic of NIID [ 15 ]. No changes have been found in the central or peripheral nervous system.

Genetic mutations may also result from contracted viruses, environmental factors, such as UV radiation from sunlight exposure, or a combination of any of these.
