In this podcast, Marcus talks broadly about why genetics is so important for people with mental illness. He presents different kinds of genetics research including the genome-wide association studies that have made such significant breakthroughs in recent years, and the exciting technique called Mendelian randomisation, which helps us to find causal associations in observational data.
