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.

Changes in the XIRP2 gene were identified in a UDN participant with heart abnormalities, global developmental delay, brain MRI abnormality, and seizures (infantile spasms) that are now well treated and controlled (read full description).
