Clinical research: Metabolic disorders rare in autism

by  /  23 August 2011

Screening for metabolic disorders in children with autism is not cost-effective, according to a study published 7 July in PLoS One. The researchers argue instead for careful individual clinical analysis.

Genetics: Gene variants can predict autism severity

by  /  19 August 2011

Children with autism who carry a certain variant of a protein involved in inhibitory signaling have more severe symptoms than those with another variant of the same gene, according to a study published 24 July in the Journal of Autism and Developmental Disorders.

Molecular mechanisms: MeCP2 regulated by chemical switch

by  /  17 August 2011

MeCP2, the protein missing in people with Rett syndrome, enhances learning and memory by binding to key genes and either activating or inhibiting their expression, according to a study published 17 July in Nature Neuroscience. Adding a phosphate to the protein in response to neuronal activity releases MeCP2 from these genes, the study found.
