Genes

New versions of the DNA editor CRISPR enable scientists to turn off specific genes in rats, detect mutations in human tissue and delete segments of the genome.

Mice colonized with gut microbes from some autistic boys show behaviors like those of the boys.

Spontaneous mutations that occur between genes may be as important in autism as those within genes.

An array of minute beads enables researchers to build precise maps of gene expression in the brain.

A set of neurons involved in complex cognitive functions may play a central role in autism.

A website called GeneMatcher has helped researchers identify a new gene for intellectual disability, developmental delay and autism.

A person’s genetic makeup can ease or worsen the effect of mutations linked to autism.

A new computational method sifts true mutations from spurious ones in a single cell’s genome.

Autistic children may be more likely than their unaffected siblings to carry mutations in genes linked to sleep.
