Autism Speaks recently announced the release of biological and clinical data from 383 new families participating in Autism Speaks Autism Genetic Resource Exchange (AGRE). The data will greatly help researchers study the genetic and environmental influences on development of the developmental disorder.
Autism Speaks is the world's leading autism science and advocacy organization. AGRE is a resource for scientists that is comprised of clinical and biological data from families who have two or more children on the autism spectrum; AGRE now provides data on 3348 individuals with an autism spectrum disorder (ASD) and a total of 9335 people including non-autistic family members.
"One of the biggest challenges for researchers is trying to recruit families and gather information for their research in a timely manner," said Autism Speaks Vice President of Clinical Affairs Clara Lajonchere. "AGRE accelerates the pace of research by taking these time-consuming steps out of the hands of researchers, so they can spend their time and effort analyzing the data and looking for answers now." AGRE's job has been to gather DNA, clinical, and medical information from families throughout the United States, making it the world's first collaborative resource for autism research worldwide.
Thus far, the data collected and made available by AGRE has resulted in 205 significant research publications. One example of the exciting research being done with AGRE data is a study published in 2011 that found that pregnancy and the birth environment may affect development of autism in twins. The ground breaking study suggested that environmental influences, which could include parental age, low birth weight, multiple births, and maternal infections during pregnancy, may greatly increase risk for ASD. The findings support the notion that both genetic and shared environmental factors significantly increase risk for ASD: an estimated 38 percent of risk being associated with genetic heritability and 58 percent with the environment that twins share during pregnancy and perhaps early infancy. The study also found that the relative contributions of shared genes and shared environment are similar for males and females.
"The data on these new families, also available through the National Database for Autism Research (NDAR), further enhances the informatics infrastructure developed by Autism Speaks and the NIH," commented Dan Hall, NDAR project science manager. Combining these data, with those collected across many other projects gives researchers an unprecedented opportunity to accelerate scientific discovery."
Though AGRE was able to collect data on over 1,700 families nationwide, it became apparent that this in-home model of collection needed to adapt in order to meet the growing needs of the autism research community. In an effort to continue its mission to accelerate the pace of autism research, Autism Speaks has decided to transition AGRE to an outsourced model of collection. In this innovative new model, data collection will take place at a variety of centers nationwide (most immediately at several sites in Autism Speaks Autism Treatment Network) and be centralized and made available through AGRE. This creates a one-stop shop for researchers to access an exponentially growing resource and allows the studies to focus on collection.
Autism is a general term used to describe a group of complex developmental brain disorders – autism spectrum disorders – caused by a combination of genes and environmental influences. These disorders are characterized, in varying degrees, by communication difficulties, social and behavioral challenges, as well as repetitive behaviors. An estimated 1 in 88 children in the U.S. is on the autism spectrum – a 78 percent increase in six years that is only partly explained by improved diagnosis.
About Autism Speaks
Autism Speaks is the world's leading autism science and advocacy organization. It is dedicated to funding research into the causes, prevention, treatments and a cure for autism; increasing awareness of autism spectrum disorders; and advocating for the needs of individuals with autism and their families. Autism Speaks was founded in February 2005 by Suzanne and Bob Wright, the grandparents of a child with autism. Mr. Wright is the former vice chairman of General Electric and chief executive officer of NBC and NBC Universal. Since its inception, Autism Speaks has committed over $180 million to research and developing innovative resources for families. Each year Walk Now for Autism Speaks events are held in more than 95 cities across North America. On the global front, Autism Speaks has established partnerships and related activities in over 40 countries on 5 continents to foster international research, services and awareness.
