Achondroplasia is a genetic disorder that affects bone growth, leading to a form of dwarfism. Individuals with achondroplasia typically have a 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 regulating bone development. People with achondroplasia often have a larger head, shorter limbs, and a prominent forehead. While the condition does not affect intelligence, it can lead to certain health issues, such as spinal problems and ear infections. Early diagnosis and supportive care can help manage these challenges effectively.
