When a genetic variant is shared by only a handful of individuals worldwide, what does it mean for diagnosis, treatment, and research? In this session, we’ll explore the complexities of interpreting ultra-rare genetic mutations, especially in the context of mitochondrial disease. How do clinicians and geneticists determine whether a novel or rare variant is pathogenic? What frameworks are used to classify variants, and how do phenotypic data contribute to this process? Can a “variant of uncertain significance” (VUS) eventually be reclassified as clinically meaningful? Join Dr. Rossana Sanchez, Assistant Professor and Pediatric & Metabolic Geneticist at Emory Genetics, for an in-depth discussion on the scientific, clinical, and emotional challenges faced by individuals in the mitochondrial disease community who truly are “the rare among the rare.”
