By identifying in the early 2000s the first genes associated with Asperger's syndrome, a form of autism without intellectual disability, Professor Thomas Bourgeron triggered a change in the way we look at all autism spectrum disorders.
This paved the way for improved diagnosis and support for patients, whose number is estimated at 700,000 people.
- Since when do we know the genetic origin of autism?
As early as the 1970s, the first studies on monozygotic and dizygotic twins highlighted the genetic component of autism.
They were later confirmed by research on thousands of sets of twins.
We also saw that, in the same family, the probability of having another autistic child was higher (we now know that it is one in five).
Twenty years later, we began molecular analyzes to identify the genes concerned, the type of variations involved...
