GW professor discovers new information in the understanding of autism and genetics

the Cxcr4 cytokine receptor.

"This gives us two pieces of the puzzle for this genetic developmental disorder," said LaMantia. "These two pieces tell us that in very early development, those with 22q11.2 deletion syndrome do not make enough cells in one case, and do not put the other cells in the right place. This occurs not because of some degenerative change, but because the mechanisms that make these cells and put them in the right place during the first step of development have gone awry due to mutation."

The next step in LaMantia's research is to probe further into the molecular mechanisms that disrupt the proliferation of projection neurons and migration of interneurons. "If we understand that better and understand its consequences, we can go about fixing it," said LaMantia. "We want to understand why cortical circuits don't get built properly due to the genetic deletion of chromosome 22."
