Back to EpisodesUnderstanding Homocystinuria (HCU): How one Mother Uncovered her Son's Diagnosis
Description
Melanie, mom to 12-year-old Masen, shares the unexpected path to her son's diagnosis with Homocystinuria (HCU) after a routine eye exam revealed something "off." What followed was months of uncertainty, a rare diagnosis few providers had even heard of, a crash course in low-protein diets and metabolic formulas, and two back-to-back eye surgeries to prevent further damage. With gentleness, honesty, and deep advocacy, Melanie describes how they adjusted as a family, how Masen built resilience, and how finding community changed everything. A story of early detection, parent intuition, and the power of connection.
