Isovaleric Acidaemia

Isovaleric acidaemia is a rare inherited disorder in which the body cannot fully break down the protein building block leucine. Isovaleric acid then builds up, which can cause vomiting, poor feeding, drowsiness and a distinctive sweaty-feet odour, sometimes with dangerous metabolic crises. It is often picked up on newborn screening. Management involves a leucine-restricted diet, carnitine or glycine supplements, and an emergency plan for illness.
