Studying the well-characterized Williams syndrome could help researchers understand autism and discover new therapeutic targets, says Andreas Meyer-Lindenberg.

Expert opinions on trends and controversies in autism research.
Among siblings of children with autism, those with better prefrontal cortex functioning — observable as relatively strong executive functions for their age — are better able to compensate for atypicalities in other brain systems early in life, and are therefore less likely to receive a diagnosis of autism later in their development, argues Mark H. Johnson.
Genes and the environment each influence the role of the other in determining the risk of developing autism. Genetics can determine how susceptible one is to the environment, and environmental factors can influence gene expression and introduce mutations, says immunologist Janine LaSalle.
Studying tuberous sclerosis provides researchers with a unique opportunity to find a common pathway among the various genetic causes of autism, says neurologist Mustafa Sahin.
Understanding the function of neuronal circuits, specifically microcircuits in the prefrontal cortex and elsewhere in the brain, will play a major role in translating research findings into new autism treatments, says Vikaas Sohal.
To find the pathogenic mutations in complex disorders such as autism, researchers may need to conduct sophisticated analyses of the genetic functions that are disrupted, says geneticist Aravinda Chakravarti.
