EP 222: From genetic risk to gene editing in heart failure with Travis Hinson of JAX and UConn

Описание: This week on The Genetics Podcast, Patrick is joined by Dr. Travis Hinson, Professor and physician at the University of Connecticut and investigator at the Jackson Laboratory. They discuss how genetics is reshaping the understanding of heart failure, why sarcomere biology has become a central target for new gene-based therapies, and how advances in genome editing and preventive genetics could redefine cardiovascular care.
