Autism all in the genes?
The DNA of over 10,000 people was analysed in the study
The genetic make-up of people may influence whether they develop autism, scientists have claimed.
New research funded in part by the National Institutes of Health
(NIH) in the US identified a number of factors that appear to affect the likelihood of a person having autism spectrum disorder (ASD).
Published in the journal Nature, the study saw experts analyse the DNA of over 10,000 subjects and revealed that there are several genetic variants commonly associated with the condition.
All of them pointed towards two genes of chromosome five which are responsible for how cells connect to each other.
This differs from previous studies on the subject, which have only served to highlight the complexity of the issue by identifying just a few rare genetic risk factors.
According to Dr Raynard Kingston, acting director of the NIH, the findings provide evidence that genetics play "a strong role" in ASD.
"Detailed analysis of the genes and how they affect brain development is likely to yield better strategies for diagnosing and treating children with autism," he added.
According to the National Autism Society, around one in 100 people currently have the condition in the UK.
It is also believed to affect more men than women.
