BCL11B

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 BCL11B gene was identified in a female, age 29, with global developmental delay, intellectual disability, brain abnormality (Arnold-Chiari type I malformation), overactive thyroid (hyperthyroidism), and brittle bones (osteopenia) (read full description).
