Some types of restricted and repetitive behaviors become more prevalent among autistic children and teenagers over time, depending on their age and intellectual ability, whereas others decrease.

Cross-species comparisons can help make sense of subtle genetic variants in people with autism and identify hundreds of new genes that may contribute to the condition.
A new protocol aims to help researchers include more autistic people — especially those who are minimally verbal or have intellectual disability — in imaging studies.
There is not yet a single example of a gene that, when mutated, increases the likelihood of autism but not of other neurodevelopmental conditions, including intellectual disability.
People with mutations in distant chromosomal regions often share a range of autism traits, even if they do not meet the diagnostic threshold for autism.
Autistic children’s traits track with subtle, autism-like behaviors in their mothers; women with these traits may also carry a genetic predisposition to the condition.
Conversations between an autistic and a typical person involve less smiling and more mismatched facial expressions than do interactions between two typical people.
About 0.7 percent of children in China aged 6 to 12 — and 1.15 percent of 10- and 11-year-olds in Greece — have autism, figures that are consistent with prevalence estimates elsewhere.
