Oculopharyngodistal myopathy


Title




Other Names:
OPDM; Oculopharyngeal distal myopathy
Categories:
Congenital and Genetic Diseases; Eye diseases; Nervous System Diseases
This disease is grouped under:
Muscular dystrophy

Summary Summary


Listen
Oculopharyngodistal myopathy (OPDM) is a rare, adult-onset hereditary muscle disease.[1][2] 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.[1][2][3] 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.[1][3]

This table lists symptoms that people with this disease may have. For most diseases, symptoms will vary from person to person. People with the same disease may not have all the symptoms listed. This information comes from a database called the Human Phenotype Ontology (HPO) . The HPO collects information on symptoms that have been described in medical resources. The HPO is updated regularly. Use the HPO ID to access more in-depth information about a symptom.

If you need medical advice, you can look for doctors or other healthcare professionals who have experience with this disease. You may find these specialists through advocacy organizations, clinical trials, or articles published in medical journals. You may also want to contact a university or tertiary medical center in your area, because these centers tend to see more complex cases and have the latest technology and treatments.

If you can’t find a specialist in your local area, try contacting national or international specialists. They may be able to refer you to someone they know through conferences or research efforts. Some specialists may be willing to consult with you or your local doctors over the phone or by email if you can't travel to them for care.

You can find more tips in our guide, How to Find a Disease Specialist. We also encourage you to explore the rest of this page to find resources that can help you find specialists.

Healthcare Resources

  • To find a medical professional who specializes in genetics, you can ask your doctor for a referral or you can search for one yourself. Online directories are provided by the American College of Medical Genetics and the National Society of Genetic Counselors. If you need additional help, contact a GARD Information Specialist. You can also learn more about genetic consultations from MedlinePlus Genetics.
