Exploring enigmatic links between mitochondria and autism

by  /  8 January 2013

Mitochondrial deficits may account for the range of symptoms and neurological deficits seen in autism and explain why it preferentially affects boys, says Douglas Wallace.

Mouse model links autism risk gene to mitochondria

by  /  11 October 2012

A new mouse model provides the first molecular link between the known autism risk gene PTEN and the mitochondrial dysfunction sometimes seen in the disorder. Mice with half the normal amount of PTEN protein in their brains have social deficits reminiscent of autism and faulty mitochondria, according to a study published 10 August in PLoS One.

Expression data links gene candidates to autism

by  /  11 July 2012

Identifying genetic variants that affect the expression of other genes can enhance traditional gene association analyses and highlight candidate risk factors for autism, according to a study published 16 May in Molecular Autism.

Defects in carnitine metabolism may underlie autism

by  /  10 May 2012

A genetic defect in the synthesis of carnitine, a molecule that is essential for proper mitochondrial function, might slightly increase risk for autism in some children, according to research published 8 May in the Proceedings of the National Academy of Sciences.

Molecular mechanisms: Autism protein forms aggregates

by  /  13 March 2012

DISC1, an autism-associated protein, can form large aggregates that deplete the amount of functional DISC1 in cells, according to a study published 14 February in Human Molecular Genetics.

Research evolution

by  /  3 January 2012

A new study examining trends in autism research over the past 40 years found that the largest areas of growth have been in immune function, oxidative stress, toxin exposure, genetics and neuroimaging, while research on theory of mind and neuropathology has slowed.

Mouse models point to early troubles in tuberous sclerosis

by  /  28 November 2011

The brain abnormalities characteristic of tuberous sclerosis may begin early in development and involve malfunctioning of neuronal precursors, according to studies of two different mouse models of the disorder published in October.
