SFARI Base is a central database of phenotypic and genetic information about families affected by autism and other neurodevelopmental disorders, provided as part of the Simons Foundation Autism Research Initiative (SFARI). It contains data from the following cohorts:

Approved researchers can access phenotypic data, order biospecimens, order genetic or imaging data, and/or recontact families for future research studies. Instructions on how to access SFARI Base and request these resources are detailed below.


  • Not all types of data and biospecimens are available for every cohort and subject.
  • The use of SSC, Simons VIP and AIC data and biospecimens is limited to projects related to advancing the field of autism and related developmental disorder research. Applications will be reviewed to ensure the use of data and biospecimens is in compliance with the Institutional Review Board (IRB)-approved consent language.
  • The use of SPARK phenotypic and genomic data is not limited to projects designed specifically to advance the understanding of autism and related developmental conditions. Applications for access to data will be reviewed for approval. Availability may be restricted based on the interests of the participants and the status of related, ongoing research. Investigators are encouraged to collaborate in their approaches to SPARK data.
