Novel Somatic Mutation in LEMD3 Splice Site Results in Buschke-Ollendorff Syndrome with Polyostotic Melorheostosis and Osteopoikilosis.

Abstract excerpt

Buschke-Ollendorff syndrome is a rare autosomal dominant disorder caused by loss of function in LEMD3, resulting in connective tissue nevi and varying bone dysplasia. Although typically benign, we describe a novel LEMD3 splice site mutation (IVS12 + 1delG) in a 13-year-old boy with Buschke-Ollendorff syndrome presenting with severe skeletal deformities, polyostotic melorheostosis, and osteopoikilosis.
