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 change in this gene was identified in a female, age 5 with seizures (tonic seizures and spasms) that are resistant to treatment (refractory), global developmental delay, autism, and intermittent problems with coordination (gait ataxia) (read full description).
