This is the case of a 9-year-old girl who initially presents with episodes of syncope and potentially concerning family history. An extensive evaluation is unrevealing, and she appears to have simple benign autonomic dysfunction. Eventually, a rare and life-threatening disease is uncovered, and she receives appropriate treatment. The case report highlights the persistence and suspicion of the managing providers that ultimately allowed the diagnosis to be revealed as well as some of the key features of the underlying disease.
