Autism Genes Identified?

The genetic basis of Autism has long been recognized due to the observation that the disorder tends to run in families. But what are the genes responsible for the disorder? A group of researchers  may have found the answer. A study of 661 families in the UK, the Netherlands, Germany, and Italy has identified two genes: LRRN3 and LRRTM3 that appear to be associated with increased risk for Autism Spectrum Disorders (ASD).

The proteins encoded by these two genes have been implicated in brain development, which is often impaired in autistic individuals. In particular, LRRN3 is thought to play a role in the development and maintenance of the nervous system, while LRRTM3 is part of a family of proteins thought to organise synaptic connections.

More research on how these genes function may provide greater insight on their role in ASD, and help scientists gain a deeper understanding of how autism develops.  Click here for the full article.
