The world’s largest genetic study of people with autism has pinpointed 18 new genes that are linked to the condition.
The discovery could help identify new sub-types of the condition, as well as help explain its causes, researchers claim.
The find could also explain why people with autism often have other medical conditions, including adult diabetes and heart problems.

The genes were identified by the largest ever autism genome sequencing programme, which was funded by advocacy group Autism Speaks.
‘It’s noteworthy that we’re still finding new autism genes, let alone 18 of them, after a decade of intense focus,’ said Dr Mathew Pletcher, vice president of Autism Speaks, who led the study.
‘With each new gene discovery, we’re able to explain more cases of autism, each with its own set of behavioural effects and many with associated medical concerns.’
The study involved the analysis of 5,205 whole genetic sequences from families affected by autism.
To date, scientists have identified 61 genetic variations that affect the risk of autism.
Finding genes that are linked to autism could help deepen our understanding of the condition’s many different effects, Dr Pletcher said.
Autism Spectrum Disorder (ASD) can cause a wide range of symptoms, which include problems with communicating with others and perceiving the the world.
‘The unprecedented database is enabling research into the many ‘autisms’ that make up the autism spectrum,’ said the study’s senior investigator, Dr Stephen Scherer
