What is DLG4-related syndrome?
DLG4-related syndrome happens when there are changes to the DLG4 gene. These changes prevent the gene from working as it should. DLG4-related syndrome is also called SHINE syndrome and DLG4-related synaptopathy.
The DLG4 gene contains the instructions for making a protein called PSD-95. The PSD-95 protein plays a key role in communication between brain cells. This communication happens in the spaces between brain cells called synapses. This is why the syndrome is also called DLG4-related synaptopathy.
Most people who have DLG4-related syndrome have:
- Intellectual disability (98 percent)
- Developmental delays in early childhood (84 percent)
Other common symptoms include:
- Epilepsy (53 percent)
- Autism spectrum disorder (55 percent)
Do people who have DLG4-related syndrome look different?
People who have DLG-4 related syndrome may look different. Appearance can vary and may include one or more of these features:
- Long face
- Thin eyebrows
- Thin upper lip
- Wide nasal bridge
- Broad nose tip
32 percent of people who have DLG4-related syndrome have abnormal brain MRI findings
