Maple Syrup Urine Disease

Maple Syrup Urine Disease (MSUD) is a genetic autosomal recessive metabolic disorder where the body cannot metabolize branched-chain amino acids, leading to a distinctive sweet odor in urine and earwax, and if left untreated through diet modification, it can result in severe neurological symptoms and death within weeks to months. It was first described by John Menkes in the 1950s.
