Cockayne syndrome type III



Cockayne syndrome is a rare disease which causes short stature, premature aging (progeria), severe photosensitivity, and moderate to severe learning delay.[1] This syndrome also includes failure to thrive in the newborn, very small head (microcephaly), and impaired nervous system development. Other symptoms may include hearing loss, tooth decay, vision problems, and bone abnormalities.[2] There are three subtypes according to the severity of the disease and the onset of the symptoms:[2][3]
Cockayne syndrome is caused by mutations in either the ERCC8 (CSA) or ERCC6 (CSB) genes. Inheritance is  autosomal recessive.[2] Type 2 is the most severe and affected people usually do not survive past childhood. Those with type 3 live into middle adulthood.[1] There is no cure yet. Treatment is supportive and may include educational programs for developmental delay, physical therapy, gastrostomy tube placement as needed; medications for spasticity and tremor as needed; use of sunscreens and sunglasses; treatment of hearing loss and cataracts; and other forms of treatment, as needed.[3]

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


Support and advocacy groups can help you connect with other patients and families, and they can provide valuable services. Many develop patient-centered information and are the driving force behind research for better treatments and possible cures. They can direct you to research, resources, and services. Many organizations also have experts who serve as medical advisors or provide lists of doctors/clinics. Visit the group’s website or contact them to learn about the services they offer. Inclusion on this list is not an endorsement by GARD.
