Achondroplasia is a genetic disorder causing disproportionate dwarfism, where certain body parts are small while others remain of average or above-average size. Primarily caused by mutations in the FGFR3 gene, this condition is often present at birth. Recognizable symptoms include short arms and legs, an enlarged head, and a normal-sized torso. Diagnosis can be made during pregnancy or after birth through techniques like ultrasound and genetic testing.
