SATB2-Associated syndrome (Glass syndrome)

SATB2-Associated syndrome (SAS, Glass syndrome) is an autosomal dominant multisystem disorder characterized by significant neurodevelopmental compromise with limited to absent speech, intellectual disability of variable severity, behavioral issues, skeletal anomalies, and craniofacial abnormalities. More details can be found on Genereviews.

What is SATB2-Associated syndrome

SATB2 -Associated syndrome (SAS) is a rare genetic condition. While knowledge and awareness on SAS continues to improve, most people have not heard of it. The core features of SAS can be remembered by the following acronym using the name of the SATB2 gene:

S: Severe speech anomalies
A: Abnormalities of the palate
T: Teeth anomalies
B: Behavioral issues with or without Bone or Brain MRI anomalies
2: 2 years of age or earlier is usually the age of onset

In these videos you'll get an overview of the main features of SAS. You have the option of a simple and quick version or a more detailed version with more information.

How to enter the SATB2 Registry

SATB2 Registry information

This large worldwide registry for SATB2-Associated syndrome (SAS) is led by Dr. Yuri Zarate and Katie Bosanko. After you contact the team, the participation consent is sent and reviewed for questions. Next, a link to the database with SAS-specific questions is sent to the family to complete. The registry team collects medical records from providers and provides a high level of data curation. The registry has provided a great deal of information that is published in the literature as it is analyzed.

Arkansas Children’s Hospital hosts the only dedicated multidisciplinary clinic for the SATB2-Associated syndrome in the United States. This clinic is hosted quarterly and participants can anticipate undergoing a comprehensive evaluation by our experienced SATB2 team. More information at SATB2 International Clinic (archildrens.org).


Portal version

This is the alpha version of the SATB2 Portal

The SATB2 Portal is the result of a collaborative effort to disseminate quality relevant data generated during the study of SATB2-Associated syndrome.

The goals of this project are:

  • Summarize clinical and molecular data interactively
  • Provide information on SATB2 -Associated syndrome
  • Support and promote research on SATB2-Associated syndrome
  • Facilitate ongoing recruitment to the SATB2 -Associated syndrome registry

  • Aid in SATB2 variant interpretation and classification
  • Visualizing data from the global SATB2 -Associated syndrome registry
  • Promote collaboration between clinicians and other researchers

Teams and People

The current version of the SATB2 Portal has been developed by an international team of researchers and clinicians:

Data generation information

Information for this portal is obtained by careful review of the literature and extensive family-provided data curation. Standardized data collection forms are filled and aggregated in all instances. While we procure obtaining medical records for all individuals enrolled in the registry, in some instances, we can’t verify all information provided to be accurate. For cases reported in the literature, data is obtained from the original publication as reported by the authors.
