Everything you wanted to know about genomic imprinting but were afraid to ask

Published May 5, 2016

In the 3rd Environmental Epigenetics webinar co-organized by ASF, AS and the Escher Fund for Autism, Dr. Christopher Gregg from University of Utah describes genomic imprinting.  This is an epigenetic process where in certain genes, one copy inherited from either the mother or the father is silenced, so only the other is expressed.  Imprinting is the cause behind Prader Willi and Angelman Syndrome, and might be associated with autism as well.  Even more interesting is that early exposures to environmental chemicals can alter imprinting marks in the sperm and the egg.  Want to know more?  Watch the whole webinar here:  http://asfpodcast.org/?p=189
