Genes

Genetic variants that contribute to autism may also be involved in attention deficit hyperactivity disorder and Tourette syndrome, according to a new study.

People with mutations in distant chromosomal regions often share a range of autism traits, even if they do not meet the diagnostic threshold for autism.

A new approach for delivering gene therapy to the brain reduces nerve damage in primates and could help make gene therapies for conditions related to autism safer.

Mice missing a copy of MAGEL2 have trouble discerning between a familiar mouse and an unfamiliar one; treating them with the social hormone vasopressin reverses this deficit.

Mutations in genes that encode a histone, which gives structure to chromosomes, can lead to developmental delay and congenital anomalies.

Mutations in the autism-linked gene DNMT3A lead to the behaviors and gene-expression changes seen in different neurodevelopmental conditions.

Cells with excess UBE3A, an autism-linked protein, have atypical firing properties that can be corrected by limiting the protein’s levels, according to new research.

Sleep disruption early in life has long-lasting consequences for mice missing a copy of the autism-linked gene SHANK3.

Two unpublished studies detail improved techniques for delivering gene therapies to the brain.

Female mice missing a copy of the autism-linked gene MECP2 in a specific set of inhibitory neurons have a hard time heeding pups’ calls and herding litters.
