Random genetic changes may explain variability in autism

by  /  13 April 2010

Random changes in gene expression can cause genetically identical embryos to develop different traits, according to a study of worms published in Nature. The findings suggest that haphazard movements of molecules could partly explain why autism-associated mutations don’t always cause the same symptoms.

Rett gene found to control genome structure in neurons

by  /  9 April 2010

The protein that is mutated in Rett syndrome controls the expression of other genes by changing the way DNA packs into a cell, rather than turning genes on or off, according to a study published in Molecular Cell.

Delay found in development of fragile X brains

by  /  26 March 2010

Young mouse models of fragile X syndrome show a significant lag in the development of synapses, the connections between neurons, according to a study published in Neuron. The findings suggest that a similar mistiming may be responsible for the sensory problems — such as hypersensitivity to touch and sound — sometimes seen in people with fragile X syndrome.

Studies challenge link between premature birth and autism

by  /  8 March 2010

The proposed connection between premature birth and autism may be more complicated than it seems, according to a new report. Early birth may not cause classically defined autism but, rather, may predispose children to autism-like symptoms that are part of a larger syndrome, the researchers say.
