Karthi promotes awareness oflysosomal storage diseases, a group of rare, inherited metabolic disorders. He speaks with conviction about the need to spread awareness to facilitate faster diagnosis. “The focus is now on reducing the pain experienced by children, guiding parents and providing psychological support. Once I sign up for a cause, I give it my all. If dedicating a little of my time helps, why not? Meeting these children has been a wonderful experience. They are smart and full of energy!”
