Funded by the National Institutes of Health, the National Database for Autism Research (NDAR) is a research data repository helping accelerate scientific discovery in autism research.

NDAR provides the infrastructure to store, search across, and analyse various types of data. In addition, NDAR provides longitudinal storage of a research participant's information generated by one or more research studies.

In other words, NDAR is able to associate a single research participant's genetic, imaging, clinical assessment and other information even if the data were collected at different locations or through different studies.

By doing so, NDAR gives researchers access to more data than they can collect on their own and provides robust tools to analyse the information, making it easier and faster for researchers to gather, evaluate, and share autism research information from a variety of sources.

Generally, NDAR provides the following capabilities:
• Standards to enable cross site meta-analysis and data comparisons across bioinformatics systems.
• Deployment of useful bioinformatics tools for researcher use.
• Promotion of the sharing of quality research data with autism research community.
• Query access to a repository of phenotypic, genomic, imaging and pedigree research data.
