Prospective Clinical Assessment Study in Children With Hypochondroplasia

To join this study, children need to be between two and a half and sixteen years old. They must have a clear diagnosis of hypochondroplasia, which means doctors have confirmed it both by their physical appearance (being shorter than average) and by a genetic test.

It's important that the child can walk and stand on their own without help. Also, the child and their parents or guardians must be willing and able to attend all the study appointments and follow the study instructions.

Children generally can't join if they have other conditions causing short stature, have already started puberty (if they are a girl), have recently had bone-lengthening surgery, or have certain other significant health problems that might make taking part unsafe or interfere with the study's results.

If you decide to take part, your child will have regular visits to the study clinic. During these visits, doctors and nurses will measure your child's growth (height, weight, etc.), monitor any health problems, and ask questions about their daily life, how they feel, and what they can do. There will also be some simple tests to check their thinking skills. No new medicines or treatments will be given as part of this study. The total duration of participation will depend on how long the study continues, but it is a long-term study that aims to follow children over several years to understand the condition's progression.
