Melorheostosis with osteopoikilosis

Summary Summary


Listen
The following summary is from Orphanet, a European reference portal for information on rare diseases and orphan drugs.
orphanet

Orpha Number: 1879

Definition
Melorheostosis with osteopoikilosis is a rare sclerosing bone dysplasia, combining the clinical and radiological features of melorheostosis and osteopoikilosis (see these terms), that has been reported in some families with osteopoikilosis and that is characterized by a variable presentation of limb pain and deformities.

Epidemiology
Less than 5 families have been reported in the literature to date.

Clinical description
As osteopoikilosis is a benign, usually asymptomatic condition, the clinical signs are primarily those of melorheostosis that can manifest with joint contractures, pain, stiffness, limited joint functions, limb-length discrepancy and deformity.

Etiology
The combination of melorheostosis with osteopoikilosis may be an unusual complication of familial osteopoikilosis. Osteopoikilosis is caused by a germline mutation in the LEMD3 gene (12q14). A germline mutation in the LEMD3 gene may predispose individuals with osteopoikilosis to develop melorheostosis. However, the exact pathogenesis is currently unknown.

Genetic counseling
Osteopoikilosis is inherited autosomal dominantly. There are no reports of parent to child transmission of melorheostosis. Genetic counseling is possible.
