Study picks up autism broadcast in tiny antennae on cells

by  /  8 June 2015

Mutations in a section of chromosome 16 that is linked to autism have an unexpected effect: They alter the miniscule hairs, or cilia, that adorn the surface of all cells. The findings suggest that problems with these cilia may contribute to autism.

Startled fish help sound out sensory overload in autism

by  /  8 June 2015

There is some evidence that neural habituation — the process by which neurons get used to sensory stimuli — goes awry in autism. Mutant fish may help us understand the sensory sensitivities that often accompany the disorder, says Alan Packer.

Autism-linked DNA deletion may derail brain development

by  /  2 April 2015

Missing a swath of chromosome 16 with strong ties to autism disrupts proteins crucial for early brain development. The findings open the door to targeted interventions.

Women with severe autism point to new gene candidates

by  /  26 March 2015

Looking in families with a history of severe autism among women, researchers have unearthed 18 new candidate genes for the disorder. One of these genes, delta-catenin, plays a critical role in brain development, researchers reported yesterday in Nature.

Study downgrades autism gene’s effects to rare glitches

by  /  16 February 2015

After eight years of prominence as an autism risk gene, a new analysis significantly brings down CNTNAP2’s importance in the disorder: According to the study, rare mutations in a single copy of the gene are unlikely to cause autism.
