PRKAR1B

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 PRKAR1B gene was identified in a now 8-year-old boy with low muscle tone (hypotonia), developmental delay, and increased weight (read full description).
