BSN

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.

Compound heterozygous changes in the BSN gene were identified in a UDN participant with global developmental delay, eye and vision abnormalities, and gastrointestinal dysmotility.
