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 PIEZO1 gene were identified in a male, age 5, with absolute iron deficiency anemia, behavioral problems, and recurrent infections (read full description).
