What is SAS?
SATB2-Associated Syndrome (SAS) is a rare genetic disorder caused by changes in the SATB2 gene. This gene provides instructions for making the SATB2 protein (shown above), which plays an essential role in the development of the brain, jaw, teeth, and bones.
As a result, people with SAS may have intellectual disability, limited or absent speech, behavioural differences, dental abnormalities, and an increased risk of fractures along with a range of other features.
Despite these challenges, individuals with SAS are known for their friendly personalities and unique smiles.

Frequently asked questions
Simple answers for families, supporters, and professionals who want to learn more about SAS and SATB2 Europe.
What is SATB2-associated syndrome?
SATB2-associated syndrome, or SAS, is a rare genetic neurodevelopmental condition caused by changes in the SATB2 gene. It can affect development, speech, learning, behavior, dental health, sleep, seizures, feeding, and bone health.
What are common signs of SAS?
Common features can include developmental delay, limited or absent speech, dental differences, feeding difficulties, sleep challenges, behavioral differences, seizures, and bone health concerns. Not every person has the same symptoms, and the severity can vary widely.
How is SAS diagnosed?
SAS is usually diagnosed through genetic testing. A diagnosis is made when a disease-causing change, deletion, duplication, or disruption involving the SATB2 gene is found. Families should discuss testing and results with a qualified medical professional or genetic counselor.
Is there a cure for SAS?
There is currently no simple cure for SAS. Care usually focuses on supporting development, communication, feeding, sleep, seizures, dental health, bone health, and other individual needs. Research and clinical guidance are important parts of improving future care.
