Meet Nora

Meet the Eysen family! Two-year-old Nora was diagnosed with Infantile Pompe disease at birth. Her family received much-needed information and support in those first days from the Greenwood Genetic Center, and thanks to a quick diagnosis, Nora is on treatment, healthy, and thriving. And she is now a proud big sister!...
