The illness additionally damages skeletal muscle mass and the muscle mass it’s good to breathe.
“Infants who don’t obtain ERT turn into so weak, they lose any beforehand achieved motor milestones, resembling the flexibility to roll over,” says Kishnani, the Chen household distinguished professor of pediatrics at Duke.
