Molecular mechanisms: Rett gene boosts protein production

by  /  3 December 2013

MeCP2, the protein mutated in Rett syndrome, is normally responsible for boosting the expression of a large number of genes. This finding, published 3 October in Cell Stem Cell, may explain why growth factors that promote protein production are able to reverse features of the syndrome in mice.

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.
