ASF Weekly Science Podcasts

This week we talk to Dr. Dan Geschwind from UCLA who was funded by the Autism Data Science Initiative to study thousands of environmental chemicals and medicines across various genetic backgrounds. A decade ago, this study would have taken a decade, but through new technology, robotics, and existing knowledge about genes and these chemicals, it … Continue reading "The newest most advanced way to study gene x environment interactions"

How do you know an intervention is working? It starts with making sure you are measuring the right thing. This week, Drs. Mary Wojnaroski from Nationwide Children’s Hospital and Natasha Ludwig from the Kennedy Krieger Institute who work on the Inchstone Project to talk about outcome measures around intellectual function and cognition. Some tools might … Continue reading "Clinical Trials – what you need to know about outcome measures"

Autism does not start at one, two or three years. It is a condition with trajectories, where some individuals show signs early, others later. It doesn’t just happen after some mysterious “medical event”, people are born with it. Scientists know this by tracking outcomes of those with a high likelihood of autism all the way … Continue reading "How to capture the real onset patterns of autism"

This week we talk to Drs. Steve Scherer, Lisa Bradley and Graham Collingridge who recently published research that shows the gene PTCHD1-AS influences social functioning in humans and mice, without influencing intellectual deficits. This is the newest data that shows a single gene can control social communication and not some of the other comorbid features … Continue reading "What is the evidence that autism is genetic?"

Traditionally, scientists have been able to calculate the role of genes in autism, or the environment in autism. However, understanding the role of genes together with the environment, or the effects of the environment with a genetic background, has been very difficult. This is especially true with polygenic genetic risk factors, which is not a … Continue reading "Calculating a gene x environment interaction in autism"
