Where the wild new genetic hot spots are

Three new studies, all with the common element of inclusion of ASF postdoctoral fellowships as authors, appeared this week using whole genome sequencing technologies to look at new areas of the genome.  Not just new genes, but totally unexplored ares of DNA that were only possible to examine through these newer technologies.  They are called regulatory non-coding regions, because they regulate genes known to be associated with autism – but don’t code for any proteins.  Interestingly enough, they are carried by the unaffected father.  As one of the authors on the studies and guest on this podcast, William Brandler explains, they regulate genes, they don’t cause autism, otherwise the non-affected fathers would not be non-affected.  Another ASF fellow, Donna Werling, published an analysis which called for careful consideration of the statistics around these findings.  After all, this is a relatively unexplored territory.

On Thursday, March 30th the Autism Science Foundation held their 4th Annual Day of Learning in NYC.  If you were not able to attend and can’t wait for the videos of the talks, this week’s podcast attempts to summarize what was presented.

A list of the talks are:

  • Autism Research: Where Are We Now? – Dr. Wendy Chung (Simons Foundation)
  • Housing Options for Adults with Autism – Amy Lutz (EASI Foundation)
  • Improving Communication Between Parents of Children with Autism and Teachers – Dr. David Mandell (University of Pennsylvania)
  • Developing Clinical Biomarkers – Dr. James McPartland – (Yale University)
  • Understanding Modifiable Autism Risk Factors – Dr. Craig Newschaffer (Drexel University)
  • Helping People with Autism Develop Practical Skills – Dr. Celine Saulnier (Emory University)
  • New Technologies to Improve Autism Diagnosis – Dr. Robert Schultz (Children’s Hospital of Philadelphia)
  • Understanding the Female Protective Effect – Dr. Donna Werling (University of California, San Francisco)

David Mandell’s presentation on parent/teacher communication was based, in part, on this publication:  https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4676744/

On Tuesday November 15th, Tracy Bale from University of Pennsylvania provided an insightful analysis of sex differences in behavioral, physiological and molecular outcomes following prenatal stress.  She outlined the potential epigenetic markers that may lead to resilience in female offspring which has direct implications for autism.  However, prior to Dr. Bale’s presentation, Donna Werling from UCSF briefly outlined the genetic and behavioral data so far about females with autism and why there is a 4:1 ratio in males to females getting a diagnosis.  This webinar is part of the Environmental Epigenetics of Autism Webinar Series co-organized by Autism Science Foundation, Autism Speaks and the Escher Family Fund for Autism.
