A whisper of autism: Fragile X carriers and the autism phenotype

by  /  21 April 2022

Among people who carry the fragile X premutation, about 14 percent of boys and 5 percent of girls meet the criteria for autism, but the ‘broad autism phenotype’ may be far more common.

Organoids show how mutations in top autism gene may lead to brain overgrowth in people

by  /  19 April 2022

The loss of CHD8, a top autism gene, speeds up the production of certain neurons and leads to overgrowth in spheres of cultured brain cells.
