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 the ATAD3C gene was identified in a male, who passed away at 19 months, with poor growth, a small head (severe progressive microcephaly), global developmental delay, vision and hearing impairment, autoimmune disease, and brain abnormalities (read full description).
