Below is a summary for the NSD1 gene observed in research publications. This is not meant to take the place of medical advice.
What is NSD1-related syndrome?
NSD1-related syndrome happens when there are changes to the NSD1 gene. These changes can keep the gene from working as it should.
NSD1-related syndrome is also called Sotos syndrome.
The NSD1 gene plays a key role in the basic function of the cell.
Because the NSD1 gene is important in the development and function of brain cells, many people who have NSD1-related syndrome have:
- Developmental delay and intellectual disability
- Large head size
- Tall height
- Noticeable forehead and long skull
Do people who have NSD1-related syndrome look different?
People who have NSD1-related syndrome may look different. Appearance can vary and can include some but not all of these features:
- Noticeable forehead
- Long narrow face and chin
- Thinning hair in the front
- Red cheeks, also called malar flushing
Most people with NSD-1 related syndrome have some level of intellectual disability, which can range from mild to severe.
