The Genetics Podcast

This week on The Genetics Podcast, Patrick is joined by Dr. Tim Jobson, consultant physician and gastroenterologist at Somerset NHS Foundation Trust and Medical Director of Predictive Health Intelligence (PHI). They discuss the rising burden of metabolic liver disease and how routine clinical data can be used to detect disease earlier and prevent late-stage presentation. They also discuss the LiveWell study, a collaboration between Sano Genetics and PHI, and what it reveals about layering genetics and other data types to improve risk stratification and clinical trial recruitment.
