Green List (high evidence)

Well established gene-disease association. Also known as Morquio syndrome A.

Key clinical features include short stature, skeletal dysplasia, dental anomalies, and corneal clouding. Intelligence is normal and there is no direct central nervous system (CNS) involvement, although the skeletal changes may result in neurologic complications.

Most appear normal at birth, with onset in the first few years of life. Spectrum of severity, some case reports of presentation with ascites/hydrops, severe form is associated with death by second or third decade.
