Simons Searchlight

Simons Searchlight is an initiative of the Simons Foundation Autism Research Initiative (SFARI) that aims to better understand genetic neurodevelopmental conditions, specifically those associated with autism spectrum disorder (ASD).

Previously named Simons Variation in Individuals Project (Simons VIP), the name change aims to better reflect the program’s mission to shed light on these conditions by building strong partnerships between researchers and families. In addition to the name, other recent changes include updating the community website, as well as streamlining the online registration process.

Visit Simons Searchlight to join an online support community that links families with genetic changes to each other and to research opportunities.

Currently, Simons Searchlight collects family, medical, developmental and behavioral information through online surveys and phone interviews with families and individuals. Biospecimen collection is performed either remotely or at in-person family meetings. Recently the scope has expanded to include new rare genetic disorders. Today, 153 genes and 23 CNVs are part of the Simons Searchlight community.

This expansion has been made possible through new coordinated efforts with SPARK (Simons Foundation Powering Autism Research for Knowledge), a SFARI initiative that aims to recruit, engage and retain a community of 50,000 individuals with autism and their family members living in the United States. SPARK returns genetic findings to participants who are found to carry ASD risk variants.

SPARK participants who receive a genetic diagnosis — together with any individual (worldwide) who has been given a professional diagnosis for one of the genetic conditions that are being studied by Simons Searchlight — will now have the opportunity to join Simons Searchlight. 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 and participate in studies aimed at bettering our understanding of these disorders and, in some cases, clinical trials to advance treatments.

Over 1,500 individuals with rare disorders and their families are currently registered in Simons Searchlight and more than 50 research papers have resulted from data collected from Searchlight families. These numbers are expected to grow significantly in the coming years, and so are the research opportunities for participants as well as investigators studying these conditions.

The initial phase of Simons Searchlight (Simons VIP Phase 1), which ended in early 2014, involved in-person evaluations at clinical study sites. 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.

Gene/CNV list

The Simons Searchlight gene list contains 153 gene changes (orange) and 23 copy number variants (purple) that are known to be associated with autism and other neurodevelopmental disorders. Any result returned by SPARK, another SFARI initiative, are eligible in Simons Searchlight.

Genetic variants

A list of genetic variants observed in Simons Searchlight participants can be found here (.xlsx). 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).
