SUN1

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 SUN1 gene was identified in a female, age 5 with developmental delay, seizures, congenital cataracts, hearing loss, swallowing difficulty, atrial septal defect, repetitive behaviors (stereotypy), low blood platelet levels (thrombocytopenia), anemia, and a blueberry muffin rash identified at birth (read full description).
