This week a 5 country collaboration including the largest number of people EVER revealed 80% of the causes of autism are heritable. This is incredibly important to understand autism and move forward with research that matters to families.  What it did not do was calculate the role of gene x environment interactions which seems to be the forgotten stepchild of autism research.  This week’s #ASFpodcast explains why it is important to understand the heritability while at the same time study the combined effects of genetic and environmental factors.

This holiday weekend always triggers a reincarnation, a resurrection of the vaccine – autism hypothesis.  Many of you have read about the measles epidemics that are hitting many areas of the country.  But besides vaccines, there are other aspects of the immune system that may be linked to autism in some people.  The include family history of autoimmune disorders as well as specific genetic mutations that confer protection against subtypes of ASD.  This week’s ASF podcast will explore these theories and present different ideas on how the immune response is involved in autism, and if it is at all.
