description

You're born with your unique genetic makeup. But, your genes are not set in stone. DrBonnie360 brings Judy from Stanford Medicine X to the Festival of Genomics to show that genes are not our destiny. Through various omics studies we see that Judy's autoimmune genetics may be adjustable. Learn how you can DIY your fate
