On this page, you will find information about a genetic change that was identified in a UDN participant. We are trying to find others with the same or similar condition.

Sharing information on this website is not a requirement of UDN participation. Only descriptions about participants who give explicit consent will appear here.

A mosaic change in the CHD5 gene was identified in a female, age 4, with seizures, global developmental delay, and optic nerve hypoplasia (read full description).
