Scientists probe puzzling overlap of epilepsy and autism

by  /  12 May 2011

Large studies on the epidemiology and genetics of epilepsy and autism have uncovered commonalities between the two disorders. But scientists are only beginning to untangle the biological roots of the overlap.

Genetics: Deep sequencing reveals rare mutations

by  /  5 April 2011

Rare mutations with strong effects play a key role in autism and schizophrenia, according to a study published in February in PLoS Genetics. The study identifies rare harmful mutations in three candidate genes that are more common in individuals with one of the disorders than in controls.

Genetics: Including gender improves autism genetics research

by  /  24 January 2011

Accounting for gender increases the power of family-wide studies linking genetic mutations with autism, according to a study published in December in Molecular Psychiatry. The researchers use this approach to identify two candidate genes for the disorder.

Mouse model of Timothy syndrome shows social deficits

by  /  15 November 2010

Mice bearing the genetic defect that causes Timothy syndrome show many autism-like behaviors, and may also have enhanced cognitive abilities like those seen in a small number of people with autism, suggests a poster presented Sunday at the Society for Neuroscience annual meeting in San Diego.

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.

Synaptic defects link autism, schizophrenia

by  /  2 July 2010

Several independent groups have found previously unknown risk genes for autism, schizophrenia and mental retardation. The candidate genes have one thing in common: they encode proteins that are needed for the healthy function of synapses, the junctions between neurons.

Researchers identify biological roles for fragile X protein

by  /  1 June 2010

FMRP, the protein missing in fragile X syndrome, is needed for the birth of new neurons, for regulating the translation of RNA into protein, and for maintaining the structural integrity of spiny neuronal projections, according to several new studies.

Measuring expression

by  /  14 April 2010

To examine protein interactions inside brain cells, scientists typically zero in on one gene at a time. A new method described in today’s Nature simultaneously measures expression of the whole genome.

Chemical messenger variant found in families with autism

by  /  16 December 2009

Scientists have for the first time found direct evidence that defects in the GABA receptor sometimes give rise to autism, according to research published 24 November in Molecular Psychiatry.

Mounting evidence fingers mitochondria in autism risk

by  /  8 December 2009

Using new genetic screening technology, a few research groups are finding that a surprisingly large number of children with autism — at least five percent — have an underlying problem with their mitochondria, the energy factories of the cell.
