CODAS syndrome


Title




Other Names:
Cerebral, ocular, dental, auricular, and skeletal syndrome; Cerebro-oculo-dento-auriculo-skeletal syndrome
Categories:
Congenital and Genetic Diseases; Musculoskeletal Diseases

Summary Summary


Listen
The following summary is from Orphanet, a European reference portal for information on rare diseases and orphan drugs.
orphanet

Orpha Number: 1458

Definition
Codas syndrome is a multiple congenital anomalies syndrome characterized by Cerebral, Ocular, Dental, Auricular and Skeletal anomalies.

Epidemiology
To date, three affected children (an unrelated Canadian girl and boy of Mennonite descent, and a girl from Brazil) have been reported.

Clinical description
Characteristic features consist of psychomotor delay, cataracts, abnormally shaped teeth (including enamel projections extending from the tips of the cusps), delayed tooth eruption, malformed ears (overfolded and crumpled ears), sensorineural hearing loss, short stature with marked epiphyseal dysplasia, and an unusual facial phenotype characterized mainly by ptosis, epicanthal folds and a grooved nose.

Etiology
Etiology remains unknown but some of the features suggest involvement of a collagen gene defect.

Diagnostic methods
X-rays show delayed ossification, delayed bone age and spine and pelvic anomalies.

Differential diagnosis
The differential diagnosis should include chondrodysplasia punctata (the rhizomelic, Conradi-Hunermann, and X-linked dominant types) and Kabuki syndrome (see these terms).

Genetic counseling
The occurrence of two affected children within the Manitoba Mennonite community (a genetic isolate) suggests autosomal recessive inheritance, but other modes of transmission could not be excluded. Familial recurrence has not been documented.

Management and treatment
Management requires a multidisciplinary approach by specialists in neurology, ophthalmology, otorhinolaryngology, odontology, orthopedics and genetics.

Symptoms Symptoms


Listen

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.
