In childhood, individuals with the condition usually develop a pronounced and permanent sway of the lower back lordosis and bowed legs. Some affected people also develop abnormal front-to-back curvature of the spine kyphosis and back pain.

We want to hear from you. Cause Cause. Two specific mutations in the FGFR3 gene are responsible for almost all cases of achondroplasia. Researchers believe that these mutations cause the FGFR3 protein to be overly active, which interferes with skeletal development and leads to the disturbances in bone growth seen in this condition.
Inheritance Inheritance. Most cases of achondroplasia are not inherited. Diagnosis Diagnosis. The intended audience for the GTR is health care providers and researchers.
