IMD Research Round-Up: Mitochondrial disease

What this episode covers

The Research Round-Up returns! Hosts Silvia Radenkovic and Rodrigo Starosta are joined by Dr Hilary Vernon and Dr Austin Larson for a deep dive into the latest discoveries in mitochondrial disease. Together they explore how new biomarkers like FGF21 and GDF15 are reshaping diagnosis, how multi-omics approaches are accelerating precision care, and what large-scale data from gnomAD to stem-cell models is revealing about disease mechanisms and therapeutic opportunities. A lively, expert-led discussion connecting science, diagnostics, and patient impact across the mitochondrial field.
