CHRNA2

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 CHRNA2 gene was identified in a 12-year-old female with a history of seizures, brain imaging abnormalities, behavioral features (ADHD, hallucinations, and sleepwalking), mild to moderate bilateral sensorineural hearing loss, and distinctive facial features (read full description).
