Summary

Oculopharyngodistal myopathy-2 (OPDM2) is an autosomal dominant muscle disorder characterized by onset of distal muscle weakness, mainly of the lower limbs, and/or ophthalmoplegia in the second or third decades of life. The disorder is slowly progressive, and patients develop facial weakness, bulbar weakness, and difficulty walking or climbing stairs. Some patients may have upper limb involvement and subclinical respiratory insufficiency. Laboratory studies show increased serum creatine kinase; skeletal muscle biopsy shows myopathic changes with abnormal cytoplasmic and intranuclear inclusions (summary by Deng et al., 2020). For a discussion of genetic heterogeneity of OPDM, see OPDM1 (164310). [from OMIM]
