Achondroplasia is one of a number of chondodystrophies, in which the development of cartilage, and therefore, bone is disturbed.

Achondroplasia may be inherited as an autosomal dominant trait, which means that if a child gets the defective gene from one parent, the child will have the disorder. If one parent has achondroplasia, the infant has a 50% chance of inheriting the disorder.

Clinical trials are research studies conducted in an effort to improve overall patient health and care.


Each trial involves running supervised tests to determine the effectiveness and safety of new drugs, procedures and/or devices with the aim of answering scientific questions about a disease or condition.

Dwarfism is defined as a condition of short stature as an adult. People with achondroplasia are short in stature with a normal sized torso and short limbs.
