When Christopher Rea was born, he was a healthy baby who was hitting all his developmental milestones on time.

But when he was around 18 months old, doctors started to notice that his knees would knock together, his feet turned in and his chest was sunken in.

It wasn't until he was age four that he was diagnosed with a rare form of dwarfism that affects just one in 250,000 children worldwide.

These molecules help build a number of different body parts including skin, tendons, ligaments, cartilage and bone.

The syndrome is an autosomal recessive trait, meaning both parents must be carriers of the gene that causes Morquio for their child to be diagnosed with it.
