A drug in trials for treating autism-related disorders can reverse memory problems and anxiety in adult mice lacking the schizophrenia gene DISC1 in some cells. The unpublished results were presented yesterday in Washington, D.C.

The Rett syndrome gene MeCP2 may subtly regulate the expression of genes across the genome by altering DNA structure.

Researchers have sequenced 17 laboratory mice and mapped 56.7 million single-base DNA variants in their genomes, according to a study published 15 September in Nature. A companion paper in the same issue identifies more than 700,000 structural variants, which are insertions, deletions or other modifications of DNA.

A well-studied mouse model of autism has a smaller-than-normal volume in several autism-associated brain regions.

A new study describes a mutant mouse that, despite missing an autism-linked gene, doesn’t show any autism-like behaviors.

Mice lacking a copy of SHANK3, a gene associated with autism and intellectual disability, show marked improvements in brain signaling after being treated with insulin-like growth factor 1, according to unpublished findings presented Saturday at the International Congress of Human Genetics in Montreal, Canada.

Deleting one copy of TBX1, a gene located on the autism-linked chromosomal region 22q11.2, leads to social and communication deficits in mice.

Mouse pups with a duplication of GTF2I, a gene linked to Williams syndrome and autism, show extreme separation anxiety when separated from their mothers, according to unpublished findings presented Thursday at the International Congress of Human Genetics in Montreal, Canada.

Three common laboratory chemicals are all scientists need to create see-through brains ideal for visualizing complex neural circuits.

Two new genetic mouse models that debuted this week show that having too many or too few copies of certain genetic regions leads to an array of symptoms reminiscent of autism.
