Allen Institute for Brain Science Release: New Discovery in Autism-Related Disorder Reveals Key Mechanism in Brain Development and Disease


1/14/2013 8:56:54 AM

SEATTLE--(BUSINESS WIRE)--A new finding in neuroscience for the first time points to a developmental mechanism linking the disease-causing mutation in an autism-related disorder, Timothy syndrome, and observed defects in brain wiring, according to a study led by scientist Ricardo Dolmetsch and published online yesterday in Nature Neuroscience. These findings may be at the heart of the mechanisms underlying intellectual disability and many other brain disorders. The present study reveals that a mutation of the disease-causing gene throws a key process of neurodevelopment into reverse. That is, the mutation underlying Timothy syndrome causes shrinkage, rather than growth, of the wiring needed for the development of neural circuits that underlie cognition.
