Surplus of neurons spurs autism traits in mice

by  /  15 January 2015

Fetal mice that have too many neurons grow to show social deficits and repetitive behaviors. The finding, reported 11 December in Cell Reports, debuts a mouse model of autism that’s based on a biological abnormality seen in some people with the disorder.

Genetic encyclopedia highlights human-mouse differences

by  /  24 December 2014

Although mice and humans have many genes in common, a new catalog highlights significant differences in how these genes are regulated. This resource, dubbed mouse ENCODE, clarifies the extent to which mice can accurately model complex human diseases such as autism.

Postmortem brains point to molecular signature of autism

by  /  22 December 2014

An analysis of genes expressed in the postmortem brains of people with autism has identified three molecular pathways linked to the disorder. The findings, published 10 December in Nature Communications, add to mounting evidence that the myriad causes of autism converge on common biological processes.

Future of autism genetics should learn from its past

by  /  9 December 2014

To optimize the search for autism genes, researchers should collect large numbers of sequences — but the sequences need to be of the right kind, says Michael Ronemus.

Genetics first: A fresh take on autism’s diversity

by  /  24 November 2014

Each child with autism is different from the next. One approach rapidly gaining momentum makes sense of this diversity by grouping children together based on their genetics, then looking for patterns in their symptoms. The long-term aim: personalized treatments for each subtype of autism.
