Metabolic Diseases and their Enzymes (image) University of Massachusetts at Amherst Share Print E-Mail Caption Babies born with a faulty copy of a single gene that codes for one of several enzymes used in the cell's lysosomes -- recycling machines -- have lysosomal storage disorders of varying severity.
