Autism Gets A Genome-wide Study

A study combining family- and population-based approaches has uncovered a single-letter change in the genetic code that is associated with autism.  The finding implicates a neuronal gene not previously tied to the disorder and more broadly, underscores a role for common DNA variation. In addition, the new research highlights two other regions of the genome, which are likely to contain rare genetic differences that may also influence autism risk. read more
