Mitochondrial short-chain enoyl-CoA hydratase 1 deficiency



Other Names:
Short-chain enoyl-CoA hydratase deficiency; ECHS1D
Subtypes:

Mitochondrial short-chain enoyl-CoA hydratase 1 deficiency is an inborn error of metabolism characterized by delayed psychomotor development, neurological degeneration, increased lactic acid, and brain lesions in structures of the brain known as the basal ganglia.[1] It is one subtype of Leigh-Like syndrome.[2] Only a few cases have being reported. Symptoms may include delayed motor and speech development, hearing problems, poor muscle tone (hypotonia), poor suck, and sporadic lack of breath (apnea). Other symptoms reported include abnormal eye movements (nystagmus), heart defects, brain anomalies, and abnormal movements.[1] This condition is caused by mutations in the ECHS1 gene. It is inherited in an autosomal recessive pattern. There is only supportive treatment for the symptoms.[2]

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.
