THG1L

On this page, you will find information about genetic changes that were 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 THGL1 gene were identified in a female, age 5, with seizures, ataxia, brain abnormalities, small head size (postnatal microcephaly), and severe expressive and receptive language delay (read full description).
