In this episode, Wendy delves deep into the world of genetics by first exploring the historical landscape of genetics prior to decoding the human genome, contrasting it with what we know today thanks to whole genome and exome sequencing. She provides an overview of genetic testing by differentiating between various genetic tests such as direct-to-consumer, clinical, whole genome sequencing, and more. Additionally, Wendy unravels the genetic underpinnings of conditions such as PKU, breast cancer, obesity, autism, and cardiovascular disease. Finally, Wendy goes in depth on the current state and exciting potential of gene therapy while also contemplating the economic implications and ethical nature of gene editing.

EPISODE SUMMARY
In this episode of Peter Attia MD, featuring Wendy Chung and Peter Attia, 268 ‒ Genetics: testing, therapy, editing, association with disease risk, autism, and more explores wendy Chung on Genetic Testing, Gene Therapy, Editing, and Disease Chung explains that genetic tests differ in purpose: direct-to-consumer SNP tests like 23andMe and Ancestry are recreational or ancestry-oriented, while targeted panels, exomes and whole genomes answer medical questions with varying depth.
