Q: What is AGRE?
A: The Autism Genetic Resource Exchange (AGRE) is a program of Autism Speaks dedicated to advancing genetic research in autism spectrum disorders. Genetic biomaterials and clinical data are obtained from families that have more than one family member diagnosed with an Autism Spectrum Disorder. The biological samples, along with the accompanying clinical data, are made available to AGRE-approved researchers.
Q: How do I gain access to AGRE?
A: There are three critical steps required to gain access to the AGRE database:
Autism Genetic Resource Exchange (AGRE)
Attn: M. Harris
5455 Wilshire Blvd. Ste. 2250
Los Angeles, Ca 90036
Once your application has been received, the AGRE researcher review committee will review your application. All applications are reviewed no more than 2 weeks from the date submitted. If your application is approved, you will receive a letter welcoming you to AGRE and providing you with a username and password. This will give you immediate access to AGRE data.
Q: How do I order biomaterials from AGRE?
A: After your application has been approved and you have been given a username and password, you may download a pedigree catalog file (in Excel format) containing a listing of families, their relationships and their sample identification numbers.
Please download the AGRE Biomaterials Online Order Form from the AGRE website. Then fill out the form, save a copy to your computer and email it to Michelle Harris. Please contact the Clinical Research Specialist, Eve Landa, for pricing information. Please fax an approved purchase order for the samples.
Q: How do I select biomaterials?
A: It is important to look through the data and make sure that all the data that you are interested in can be found in the pedigrees of interest. AGRE collects phenotypic data based on the availability of the family to be scheduled for an appointment. While AGRE will only distribute pedigrees with validated ADI-R diagnoses, sample distribution may precede collection of other data.
AGRE has created a Flags list which identifies families in the collection with atypical characteristics that may make them questionable for certain genetic studies (ex. Families with a known Fragile X mutation). Therefore, it is important to identify selection criteria before purchasing biomaterials.
Q: Are AGRE samples free?
A: No. Sample acquisition, processing, and distribution are expensive processes, and we pass on a fraction of these costs to researchers. AGRE charges researchers a per sample fee for the acquisition of samples. Our prices are very competitive with other gene banks. For pricing information, please contact the Clinical Research Specialist, Eve Landa.
Q: What kinds of Biomaterials does AGRE distribute?
A: AGRE distributes DNA, Cell line and Serum samples. Please note that serum samples are NOT available for every family in the AGRE repository. Please contact the Clinical Research Specialist, Eve Landa for sample availability.
Q: What kind of data does AGRE collect and distribute?
A: AGRE collects the Autism Diagnostic Interview Revised (ADI-R) on each of the reported affected individuals. In addition, affected individuals are assessed with the Autism Diagnostic Observational Scales (ADOS). In addition to the diagnostic measurements, AGRE also collect a set of cognitive exams including the Raven Progressive Matrices, the Vineland and the PPVT. AGRE also collects medical and environmental exposure histories on the parents, affected, and unaffected children via our Online System for Clinical Research (OSCR).
While AGRE aims to eventually collect all data for all subjects in the study, pedigrees are distributed before the entire process of data collection has been completed. Therefore, it is important to choose pedigrees for your study based on the specific criteria of your study as well as the availability of the necessary data.
Q: Is AGRE affiliated with the NIMH?
A: Yes. AGRE is serving as a collection site for the NIMH Genetics Initiative. All samples collected by AGRE are placed in the NIMH repository. Samples contributed by AGRE can be found by referencing Site numbers 72 and 74.
Q: Can I recruit AGRE subjects for my study?
A: Yes. AGRE is often approached by outside organizations and research groups to collaborate on new and exciting research being done in the field. These projects range from passive recruitment of registered families for a study (sending flyers/emails) to active data collection. The families participating in the AGRE program are considered a precious resource and every effort is made to ensure that they are not overburdened. In order to accomplish this, AGRE developed a protocol for selecting and structuring collaborations that includes project vetting based on scientific merit, family burden, logistical feasibility, etc.
For further information concerning a possible collaboration, please contact the Asst. Director of Operations, Ryan Butler.
Q:Does AGRE offer any services related to the National Database for Autism Research (NDAR)?
A: Yes. Researchers can use ISAAC to federate their data, meaning that NDAR can access the data to make it available through their portal. All data shared with NDAR resides on the ISAAC system, allowing you to access and modify your data as needed. Contributing to NDAR allows researchers to conduct meta analyses across studies using de-identified global unique identifiers (GUIDs) as well as satisfy your government grant deliverables.
Q: How do I cite AGRE in a poster, presentation or publication?
A: A detailed description of citation instructions can be found here. In general, the following statement should be placed in the acknowledgements section:
