What is MYT1L -related syndrome?
MYT1L -related syndrome happens when there are changes to the MYT1L gene. These changes can keep the gene from working as it should.
The MYT1L gene plays a key role in the development of the brain.
MYT1L -related syndrome can affect the development of communication skills, social skills, and learning skills. Because MYT1L is important in the development of the brain, many people who have MYT1L -related syndrome have:
- Motor and speech delay
- Mild to moderate intellectual disability
- Excessive hunger and obesity that begins early in life
- Behavior problems, including hyperactivity and autism spectrum disorder
Do people who have MYT1L -related syndrome look different?
People who have MYT1L -related syndrome generally don’t look very different. Appearance can vary and can include some but not all of these features:
- Long chin
- Nose that has a broad base and tip
- Large mouth
- Narrow eyes
- Square-shaped trunk
Many people have speech and language delays.
In a study of 10 people with MYT1L -related syndrome, 4 had autism.
All people who have MYT1L -related syndrome show some degree of intellectual disability.
