    Geographical differences in autism prevalence can largely be accounted for by socioeconomic factors, according to research published 31 October in Environmental Health. The study confirms the importance of controlling for variables such as parents’ educational status when searching for environmental links to autism.

    By merging genetic data from two large clinical repositories, from a total of more than 30,000 children, researchers have identified 18 copy number variants (CNVs) — DNA deletions or duplications — that play a role in autism. The findings appeared 9 October in Molecular Psychiatry.

    Female mice of two different genetic backgrounds consistently model the behavioral features of Rett syndrome, according to a study published 9 October in Human Molecular Genetics. Although Rett syndrome presents almost entirely in girls, researchers have thus far relied mostly on male mice to model the disorder.
