According to the Charcot-Marie-Tooth Association (CMTA), “CMT is a rare multisystem, multiorgan disease that causes lifelong, progressive symptoms, including muscle weakness and atrophy in the arms and legs, sensory loss, and other complications.” They note:

“These symptoms often lead to challenges with balance, walking, hand use, and other daily activities.”

The agency added that Izzy passed “peacefully” and her family now “requests privacy as they deal with this sudden and shocking loss.” Those wishing to share their support have been asked to make “donations in Izzy’s memory” to CMTA HERE.
