Summary: 

This week on The Genetics Podcast, Patrick is joined by Heiko Runz, medical geneticist and VP of Neuroscience at insitro. They discuss Heiko’s path into therapeutic genetics, how collaboration and data integration across biobanks led to his discovery of a protective variant for age-related macular degeneration, and the role of cell-based models in drug discovery.
