Autism Susceptibility Genes Identified

ScienceDaily (Mar. 25, 2010) — Two genes have been associated with autistic spectrum disorders (ASD) in a new study of 661 families. Researchers writing in BioMed Central's newly launched journal Molecular Autism found that variations in the genes for two brain proteins, LRRN3 and LRRTM3, were significantly associated with susceptibility to ASD.

Anthony Monaco from the Wellcome Trust Centre for Human Genetics, University of Oxford, UK, worked with an international team of researchers to study four candidate genes in families from the UK, the Netherlands, Italy and Germany. He said, "To our knowledge, this is one of the most comprehensive genetic analyses of association between these important genes in brain connections and ASD risk."
