A practical clinical approach to the recognition of inborn errors of metabolism in the young infant is presented in this. A baby will show few signs of the disorder at birth but within a few months once molecules begin to.
Morquio syndrome also known as Mucopolysaccharidosis Type IV MPS IV is a rare metabolic disorder in which the body cannot process certain types of sugar molecules called glycosaminoglycans AKA GAGs or mucopolysaccharides.
