You may have heard of SPARK, it is the largest genetics research project in autism spectrum disorders.  But have they found anything?  Yes!  Pam Feliciano of SPARK discusses what the project is, what a pilot study has found, and how the results might help families with ASD.  In addition, a different but complementary study identified new genes associated with autism.  Given that one of them is a target of environmental factors, it’s time to spark up studies looking at gene x environment interactions as well.
