Scientists Spot Gene Tied to Severe Autism

In a recent study, researchers claim to have discovered a new genetic cause of autism, singling out a rare gene mutation. The gene, CTNND2, provides instructions for making a protein called delta-catenin, which plays a crucial role in the nervous system. Researchers found that a group of girls with severe autism carried CTNND2 mutations that appeared to reduce the effectiveness of delta-catenin, potentially affecting their neurological development.
