Exertional injuries in SCT carriers can result in exercise collapse associated with SCT (ECAST), an under\u2010recognized condition characterized by variable clinical presentations ranging from ischemic muscle pain to fulminant collapse. This study presents clinical and genetic findings of two independent Black SMs with history of ECAST triggered by strenuous exercise.
