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 female, age 5, with Noonan syndrome, systemic-onset juvenile idiopathic arthritis, and multiple congenital anomalies (read full description).
