SCIENTISTS revealed the most extensive findings to date on the genetics of autism overnight, pinpointing two new genetic links that may predispose children to develop the complex brain disorder.
The five-year study, led by an international consortium of researchers from 19 nations, indicated autism had numerous genetic origins rather than a single or a few primary causes.
The researchers scoured DNA samples from 1168 families with two or more children with autism, and used "gene chip" technology to detect genetic similarities. They also looked for tiny insertions and deletions of genetic material that could play a role in autism.
The scientists hope that nailing down the genetics of autism will lead to better ways to diagnose it and focus efforts on developing drugs to treat it. They announced they are launching a new phase in the research to map genes responsible for autism.
