What is PHIP-related syndrome?
PHIP-related syndrome happens when there are changes to the PHIP gene. These changes can keep the gene from working as it should.
The PHIP gene plays a key role in cell growth.
Because the PHIP gene is important in the development and function of brain cells, many people who have PHIP-related syndrome have:
- Intellectual disability or developmental delay
- Behavior issues, including autism
- Vision issues
Do people who have PHIP-related syndrome look different?
People who have PHIP-related syndrome may look different. Appearance can vary and can include some but not all of these features:
- High forehead
- Curved pinky finger
- Full eyebrows
- Upturned nose
- Large ears
How many people have PHIP-related syndrome?
As of 2020, about 50 people in the world with changes in the PHIP gene had been described in the medical literature.
So far, everyone who has PHIP-related syndrome has some level of intellectual disability or developmental delay.
Most people have behavior issues. This can include hyperactivity, aggression, features of autism, anxiety, or depression.
