Multi-gene deletion creates model for Angelman syndrome

by  /  7 October 2010

A new mouse model of Angelman syndrome that knocks out a large stretch of a key chromosome is clarifying some of the molecular mechanisms underlying the more severe forms of the disorder.

Fragile X protein linked to potassium channels

by  /  24 August 2010

Mouse models of fragile X syndrome show defects in two kinds of potassium channels — ubiquitous pores that control the flow of electrical current across neurons — in a brain area that processes sound, according to two papers published this summer.

Simple pathway

by  /  24 June 2010

A study of a rare form of epilepsy found in Amish groups adds heft to the idea that mTOR — a much-studied hub in a massive network of brain cell proteins — is an important biochemical player in autism.

Study implicates cell-adhesion proteins in autism

by  /  18 May 2010

Variations in two genes needed to form connections between brain cells may be associated with autism spectrum disorder, according to a study published 25 March in Molecular Autism. Some variants in the genes seem to increase susceptibility to autism, whereas others protect children from developing the disorder.

Imaging study refutes mirror neuron theory of autism

by  /  12 May 2010

Mirror neurons, which fire when someone either performs an action or observes it, are not defective in people with autism, scientists report today in Neuron. The findings dispute the theory that flaws in the mirror neuron system give rise to the disorder.

Tuberous sclerosis linked to brain cell migration

by  /  8 February 2010

The TSC2 gene, mutations in which cause tuberous sclerosis complex, is needed for budding nerve fibers to find their proper targets in the brain, according to a mouse study published in Nature Neuroscience.

Variants in synaptic protein linked to autism

by  /  9 November 2009

Scientists have identified several autism-specific variants in a gene that lies within a chromosomal region linked to the disorder, according to a poster presented at the World Congress of Psychiatric Genetics in San Diego.
