Autismus sollte nicht als einzelner Zustand mit einer Ursache angesehen werden. Diejenigen, die als kleine Kinder diagnostiziert wurden, haben in der Regel ein unterschiedliches genetisches Profil von jenen, die später diagnostiziert wurden, und findet eine internationale Studie, die auf genetischen Daten von mehr als 45.000 autistischen Menschen in Europa und den USA basiert.

I’ve linked to the news release in the post above. In this comment, for those interested, here’s the link to the peer reviewed journal article:

From the linked article:

**Autism should not be seen as single condition with one cause, say scientists**

**Those diagnosed as small children typically have distinct genetic profile from those diagnosed later, study finds**

Autism should not be viewed as a single condition with a unified underlying cause, according to scientists who found that those diagnosed early in childhood typically have a distinct genetic profile to those diagnosed later.

**The international study, based on genetic data from more than 45,000 autistic people in Europe and the US**, showed that those diagnosed in early childhood, typically before six years old, were more likely to show behavioural difficulties from early childhood, including problems with social interaction, but remain stable.

Those diagnosed with autism later, typically after the age of 10, were more likely to experience increasing social and behavioural difficulties during adolescence and also had an increased likelihood of mental health conditions such as depression.

“The term ‘autism’ likely describes multiple conditions,” said Dr Varun Warrier, from Cambridge’s department of psychiatry, senior author of the research. “For the first time, we have found that earlier and later diagnosed autism have different underlying biological and developmental profiles.”

A very relevant recent study from Princeton: Major autism study uncovers biologically distinct subtypes, paving the way for precision diagnosis and care.
