ASXL2

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 ASXL2 gene was identified in a male, age 8 who is larger than average (macrosomia) and has atypical facial features (including a large birthmark on his forehead (glabellar hemangioma)), a decrease in brain white matter (cerebral white matter atrophy), and learning difficulties (read full description).
