FLNA and skeletal dysplasia: Frontometaphyseal dysplasia (FMD) is a dominant X-linked rare disease caused by mutations of FLNA. The distinctive features of FMD include skeletal dysplasia, facial dysmorphism, extremities anomalies, deafness, cleft palate and eye anterior segment anomalies, yet none of the complications, such as acro-osteolysis, keratitis, xerosis or poikiloderma, have been reported in FMD.
