Hypochondroplasia is the result of a genetic mutation.

Common signs and symptoms of hypochondroplasia are:

‍

• Disproportionately small hands, feet, arms and legs
• Bowed legs that improve over time
• Rounding of the back
• Prominent forehead
• Mild intellectual disability

‍

Because this is a milder form of dwarfism, the condition is often not apparent at birth. It can go undetected until early childhood or as late as adulthood.

To determine if your child has hypochondroplasia, your expert doctor will conduct a physical examination, review medical history, and perform X-rays.
