Summaries for Oculopharyngodistal Myopathy 1

NIH Rare Diseases : 52 Oculopharyngodistal myopathy (OPDM) is a rare, adult-onset hereditary muscle disease. People with OPDM present with progressive eye and throat (pharyngeal) problems and involvement of the muscles of the lower legs and arms. Symptoms may include eyelid drooping (ptosis ), swallowing difficulty, hoarse and nasal voice, leg and arm weakness, as well as muscle wasting in the face and in the legs and arms. Many people have respiratory problems due to respiratory muscle weakness. In rare cases, there is also hearing loss , as well as severe weakness in muscles of the forearms and thighs. As the disease progresses, other muscles may be affected. A blood exam may show an increased creatine kinase level and an abnormal EMG. Inheritance may be autosomal dominant or autosomal recessive . The specific cause is still unknown.

MalaCards based summary : Oculopharyngodistal Myopathy 1, also known as oculopharyngodistal myopathy, is related to distal myopathy with vocal cord weakness and myopathy, and has symptoms including facial paresis An important gene associated with Oculopharyngodistal Myopathy 1 is LRP12 (LDL Receptor Related Protein 12). The drugs Carbidopa and Levodopa have been mentioned in the context of this disorder. Affiliated tissues include eye, skeletal muscle and tongue, and related phenotypes are weight loss and progressive external ophthalmoplegia

OMIM : 56 Oculopharyngodistal myopathy-1 (OPDM1) is an autosomal dominant disorder characterized by adult-onset ptosis, external ophthalmoplegia, facial muscle weakness, distal limb muscle weakness and atrophy, and pharyngeal involvement, resulting in dysphagia and dysarthria. Skeletal muscle biopsy shows myopathic changes with rimmed vacuoles. There are variable manifestations of the disorder regarding muscle involvement and severity (summary by Ishiura et al., 2019). OPDM is distinct from oculopharyngeal muscular dystrophy (OPMD; 164300), which is usually caused by a similar heterozygous trinucleotide repeat expansion in the PABPN1 gene (602279) (summary by Durmus et al., 2011).
