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 male, age 4, with a history of infantile spasms and an undiagnosed metabolic disorder (elevated alanine and lactate) (read full description).
