@yass.unitedstates: A Colorado family is mourning the loss of their 5-year-old son after he died from an extremely rare illness just days after developing what first appeared to be a simple stomachache during a family vacation. His parents are now raising awareness of Clarkson's disease, a rare condition that can rapidly cause life-threatening organ failure, in hopes that earlier recognition may help save others. #colorado #young #son #died #disease
