A rare sclerosing bone dysplasia combining the clinical and radiological features of melorheostosis and osteopoikilosis. The disease has been reported in some families with osteopoikilosis and with variable presentation of limb pain and deformities. Caused by a germline mutation in the LEMD3 gene (12q14), which may predispose individuals with osteopoikilosis to develop melorheostosis. Inheritance is autosomal dominant. [from
