Resilience and heterogeneity in ASD

Everyone knows that every person with autism has their own unique strengths and challenges. Autism is heritable, and there are over 100 genes associated with autism. There are also an unknown number of environmental factors influencing outcome, so the heterogeneity is not necessarily surprising. But why would two people with the same genetic mutation have variable outcomes? Researchers led by the Institut Pasteur in France looked at the range of outcomes in people with a rare genetic mutation associated with autism, focusing on those without an autism diagnosis. This week’s podcast is an interview with the lead author of the paper, Thomas Rolland, PhD from France. The presence of the variants in those without ASD were associated with lowered cognitive ability, education level and employment status. The bottom line of these finds are that genes affect proteins which form the brain and control brain function. However, there are multiple factors that influence outcome. Some of them may be sex or gender, prenatal exposures. It’s not just one thing, there are many things influencing an autism diagnosis.

Genetics does not equal eugenics

Sometimes when the autism community hears the words “genetics research”, it conjures up images of using genetics to eliminate people with autism. In fact, that’s not the goal of genetics research, nor is it even possible. Recently, several new studies were publish which illustrate how genetics can be used to help people understand their diagnosis, and receive more targeted supports. Special guest Jonathan Sebat from UCSD provides perspective on these findings and why genetics research is misunderstood.

Genes genes all in an order, the ones you have, the greater risk of disorder

This week, a special focus on genetics:  what type, where do they come from, what do these genes do and how do they influence risk of a wide array of psychiatric issues including autism.  The results come from the largest study to date of people with autism as well as those with ADHD, bipolar disorder and schizophrenia.  It’s also the largest study of the Female Protective Effect so far.  Even if genetics does not explain everything about ASD, genetics is important and you deserve to know why.  Below is a graphical abstract of what they found:
