Achondroplasia (Ach) is a skeletal disorder caused by gain-of-function mutations of FGFR3. Ach patients suffer from various complications such as short stature, foramen magnum stenosis and sleep apnea.

The mutated FGFR3, G380R, has an elevated activity of the receptor-associated tyrosine kinase, but G380R is further activated...
