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 CAMTA1 gene were identified in a UDN participant with progressive muscle weakness and wasting (skeletal muscle atrophy, muscular dystrophy) (read full description).
