On this page, you will find information about genetic changes that were 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.

Changes in this gene were identified in a male, age 10 with severe global developmental delay, seizures, and aggressive behavior (read full description).
