Fragile X mutation may lead to noisy brain signals

by  /  28 March 2013

Researchers have uncovered a new role for the protein missing in fragile X syndrome — it regulates the release of neurotransmitters, chemical messengers in the brain, according to a mouse study published 20 February in Neuron.


Rho family of enzymes at crossroads of autism

by  /  12 March 2013

A number of autism risk factors converge on one cellular pathway: abnormal remodeling of the cell’s structural systems through the signaling protein Rho, says SFARI’s associate director for research, Alan Packer.

Molecular mechanisms: Study links excess protein to autism

by  /  20 February 2013

Elevated levels of EIF4E, which plays a key role in protein synthesis, lead to autism-like behaviors and abnormal neuronal signaling in mice, according to a study published 17 January in Nature.


Molecular mechanisms: Pruning path links autism, fragile X

by  /  1 February 2013

The protein lacking in fragile X syndrome works with three autism-linked proteins to fine-tune the connections between neurons, according to a study published 21 December in Cell.

Hunt for targets of fragile X protein proves perplexing

by  /  31 January 2013

FMRP, the protein missing in fragile X syndrome, binds to the RNA sequences of 939 genes, 93 of which have been linked to autism, according to a study published 20 December in Nature.

Clinical research: Larger brains in autism, fragile X

by  /  19 December 2012

Young boys with fragile X syndrome or autism have larger brains overall than controls do, but the two groups show enlargement of different parts of the brain, according to an imaging study published in September in the Journal of the American Academy of Child and Adolescent Psychiatry.
