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.
"In addition to the implications for autism, what's really exciting is that we now have a way to get at the core mechanisms tying genes and environmental influences to development and disease processes in the brain," said Dolmetsch, Senior Director of Molecular Networks at the Allen Institute for Brain Science.
