About this trial
Monocarboxylate Transporter 8 (MCT8) deficiency (that is also known as Allan-Herndon-Dudley syndrome) is a rare X-linked inherited disorder of brain development that causes severe intellectual disability and problems with movement. This condition, which occurs almost exclusively in males, disrupts development from before birth.
