What is Morquio syndrome?
Morquio syndrome is a rare genetic condition that affects a child’s bones and spine, organs, and physical abilities. Children with this condition are missing or don’t produce enough of the enzymes that break down sugar chains naturally produced in the body. These chains accumulate in cells, blood, tendons, and ligaments, causing damage over time.

How is Morquio syndrome treated?
Boston Children’s treats every child diagnosed with Morquio syndrome based on the symptoms. All children need monitoring.
