Those genes hardly exhaust the list of possibilities. Among the suspects are virtually all the genes that control brain development and perhaps cholesterol and immune-system function as well. Christopher Stodgell, a developmental toxicologist at New York's University of Rochester, observes that the process that sets up the brain...
A proliferation of connections between billions of neurons occurs in all children, of course. A child's brain, unlike a computer, does not come into the world with its circuitry hard-wired. It must set up its circuits in response to a sequence of experiences and then solder them together...
Currently Courchesne and his colleagues are looking very closely at specific genes that might be involved. Of particular interest are the genes encoding four brain-growth regulators that have been found in newborns who go on to develop mental retardation or autism. Among these compounds, as National Institutes of Health...
The genes that set the stage for autistic disorders could derail developing brains in a number of ways. They could encode harmful mutations like those responsible for single-gene disorders--cystic fibrosis, for instance, or Huntington's disease. They could equally well be garden-variety variants of normal genes that...
In the end, it is not merely possible but likely that scientists will discover multiple routes--some rare, some common; some purely genetic, some not--that lead to similar end points. And when they do, new ideas for how to prevent or correct autism may quickly materialize. A decade from...
