Simons Searchlight
Simons Searchlight is a Simons Foundation Autism Research Initiative (SFARI) program that aims to better understand rare genetic neurodevelopmental conditions.
Previously named Simons Variation in Individuals Project (Simons VIP), the name change better reflects the program’s mission of shedding light on these conditions by collecting natural history data.
Simons Searchlight is an international research program that gathers family, medical, developmental and behavioral information through online surveys and phone interviews with families and individuals. Details on surveys administered can be found in the Researcher welcome packet. Biospecimen collection is performed either remotely or at in-person family conferences. Today, over 164 genes and more than 24 CNVs are part of the Simons Searchlight community, with the list always expanding.
Joining such a community enables families to find and engage with others with the same genetic condition, as well as providing opportunities to connect with researchers. Participants can also be invited to additional research studies aimed at better understanding these disorders and, in some cases, clinical trials to advance treatments.
Over 3,600 individuals with rare genetic neurodevelopmental disorders and their families are currently registered in Simons Searchlight and more than 85 research publications or preprints have resulted from data collected. Interested investigators can request access to the database through SFARI Base. The database is divided into two phases. The initial phase of Simons Searchlight (Simons VIP Phase 1) ended in early 2014 and involved in-person evaluations of 16p11.2 and 1q21.1 deletion or duplication carriers at clinical centers. There, participants underwent extensive psychological and neurological testing along with neuroimaging — including magnetic resonance imaging (MRI), functional MRI and magnetoencephalography (MEG) — with a uniform protocol and collection of biospecimens. Phase 2 data collection includes online-only measures.
Inclusion list
The Simons Searchlight inclusion list contains 24 copy number variants (orange) and 162 monogenic conditions (blue) that are associated with autism and other neurodevelopmental disorders.
Genetic variants
A list of genetic variants observed in Simons Searchlight participants can be found in the “genetic variants” spreadsheet . Where variants are found in more than one participant, counts are indicated. Variants included are classified as pathogenic, likely pathogenic, or variants of uncertain significance (VUS).
For more details, see data sets available through SFARI Base.

Research Match
SFARI launched the Research Match program in 2017. Research Match is a free service that enables approved researchers to re-contact participants from SFARI autism cohorts, including SPARK (Simons Foundation Powering Autism Research), Simons Searchlight and Simons Simplex Collection (SSC), for recruitment into new research studies.
Since Research Match launched, more than 180 projects have been conducted with participants recruited through this service, of which more than 70 projects are currently in progress. In addition, 34 papers and preprints have been published based on these studies.
To date, 2,588 families participating in Simons Searchlight have been invited to join a study; 1,435 of these families have agreed to join studies through Research Match.
Researchers interested in recruiting Simons Searchlight participants into their studies can submit an application through SFARI Base. Approved researchers will receive further information about how to contact families.
Learn more about Research Match by visiting the SFARI website and by reviewing the Simons Searchlight Research Match Recruitment Process Document.
