GNAO1

On this page, you will find information about a genetic change that was identified in a UDN participant.

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 GNAO1 gene was identified in a female, age 15, with weakness and stiffness in her limbs (spastic paraparesis), uncontrollable muscle contractions (dystonia), and slurred speech (dysarthria) (read full description).
