Girls and women with mutations in the autism-linked gene DDX3X may be particularly vulnerable to anxiety and self-harm.

A drug that prevents an enzyme from breaking down a key molecule involved in learning and memory improved cognition and behavior in a small study of men with fragile X syndrome.
A new protocol aims to help researchers include more autistic people — especially those who are minimally verbal or have intellectual disability — in imaging studies.
Motor and memory training early in life postpones the onset of difficulties in those areas in a mouse model of Rett syndrome, and stimulating neurons involved in those skills appears to mimic the effects of training.
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.
Autism and other neurodevelopmental conditions are more common among children born by C-section than those delivered vaginally, but the procedure itself does not underlie the association, according to a new study.
People with fragile X syndrome in Colombia are diagnosed at age 27, on average, according to the first study to assess diagnosis in the country. By comparison, the average age of fragile X diagnosis in the United States is younger than 4.
Altering a protein linked to Rett syndrome so that it cannot bind to a methylation tag in neurons results in Rett-like traits in mice.
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.
Merging 3D clusters of neurons that mimic different brain regions models the atypical electrical activity seen in an autism-related condition.
