Expression of an active G{alpha}s mutant in skeletal stem cells is sufficient and necessary for fibrous dysplasia initiation and maintenance [Genetics]

Fibrous dysplasia (FD) is a disease caused by postzygotic activating mutations of GNAS (R201C and R201H) that encode the α-subunit of the Gs stimulatory protein. FD is characterized by the development of areas of abnormal fibroosseous tissue in the bones, resulting in skeletal deformities, fractures, and pain. Despite the well-defined...
