Shortcast: Treatable Neonatal MoCD Type A: Rapid Demise Despite Rapid Biochemical Diagnosis

Dr Molly Crenshaw shares a powerful neonatal case of treatable molybdenum cofactor deficiency, where rapid biochemical diagnosis preceded molecular confirmation—but the infant deteriorated before disease-altering therapy could be started. This Shortcast highlights the critical value of urgent biochemical testing, evolving therapies, and the narrowing window for intervention in severe neonatal metabolic disease.
