The genetic and environmental factors that underlie difficulties with language differ from those that influence other autism traits, according to a new study of more than 3,000 twin pairs. The study, published 2 August in the American Journal of Medical Genetics Part B: Neuropsychiatric Genetics, suggests that difficulty with language is not a core symptom of autism.

A new method of statistical analysis can predict whether a rare mutation identified in someone with autism has a meaningful association with the disorder or was found only by chance, researchers reported in the September issue of Nature Genetics.

Advanced sequencing methods can detect spontaneous genetic changes that show up in only a small subset of a person’s cells, suggest two new studies published in August. Despite their low prevalence in the body, these so-called ‘somatic mosaic mutations’ occur frequently in people and may be important contributors to brain disorders.

The brains of children with autism do not prune unneeded connections between neurons as they age, leaving them with too many of these neuronal links, according to a study published 21 August in Neuron.

Creating neurons from stem cells in a lab dish is a popular approach for studying developmental disorders such as autism. But how closely these neurons resemble those found in an adult brain has been unclear. Two new methods, described 2 July in Neuron, suggest that these neurons recapitulate the early stages of development.
