These strong evidences of FGFR3 implications in the RAS/MAPK signaling pathway along with our in silico results of the interactome, let us suggest that FGFR3 disorders (thanatophoric dysplasia, achondroplasia, and hypochondroplasia) may be included among the RASopathies. The gene discussed is FGFR3; the disease is hypochondroplasia.
