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 ARHGAP6 gene was identified in a male, age 13 with intellectual disability, absent speech, seizures, abnormality of brain white matter (periventricular leukomalacia), and excess curvature of the spine (kyphosis, scoliosis) (read full description).
