Multiple Genes for Autism
Professor David Skuse explains that it is highly probable that many different genes cause autism, with each gene contributing a small part to the symptomatology.
Is there likely to be a gene for autism? The answer to that is almost certainly not. A few years ago it was thought that there was a possibility that one gene might account for a substantial proportion of the symptoms we see in conditions of autism. But over the last ten years there has been absolutely no evidence emerging that that’s the case. In fact, we now think it is more likely that there are many different genes that cause autism, no one of which will be responsible for more than a tiny proportion of the symptomatology that we associate with that disorder.

Professor David Skuse explains that although it is difficult to calculate the exact proportion of individuals with autism, estimates put the figure at about 0.6 percent.
Professor David Skuse explains that the language and social difficulties associated with autism correlate more closely than repetitive behavior symptoms.
