Achondroplasia is a genetic condition that affects bone growth, leading to a form of dwarfism. People with achondroplasia typically have shorter stature, with an average adult height of about 4 feet. This condition is caused by a mutation in the FGFR3 gene, which plays a crucial role in the development of bones and cartilage. Individuals with achondroplasia often have a larger head, shorter arms and legs, and a normal-sized torso. While they may face some health challenges, such as spinal issues or ear infections, most lead healthy lives. Support from family and medical professionals can help them thrive in their daily activities.
