Who can join the study?

To join the study, your child must:

Be younger than 15 years old

Have been diagnosed with hypochondroplasia

Be able to move and stand without assistance
(does not apply to those that are under 5 or those a bit over 3 feet tall)

Other requirements need to be met to join the 111-902 Study. Please contact us for details

Why take part?

Your child will not directly benefit from taking part in the 111-902 Study, but his/her participation will help us learn more about how children with hypochondroplasia grow, which could help others in the future.

You may be eligible to be reimbursed for study-related expenses such as travel costs.
