McCune-Albright syndrome is a disorder that affects the bones, skin, and several hormone-producing endocrine tissues. People with McCune-Albright syndrome develop areas of abnormal scar-like fibrous tissue in their bones, a condition called polyostotic fibrous dysplasia. Polyostotic means the abnormal areas lesions may occur in many bones; often they are confined to one side of the body. Replacement of bone with fibrous tissue may lead to fractures, uneven growth, and deformity.

Activating or gain-of-function GNAS1 mutations in patients with the McCune-Albright syndrome are present in the mosaic state, resulting from a postzygotic somatic mutation appearing early in the course of development which yields a monoclonal population of mutated cells within variously affected tissues. The nonmosaic state for most activating mutations is presumably lethal to the embryo. The disorder is characterized clinically by the classic triad of polyostotic fibrous dysplasia POFD , cafe-au-lait skin pigmentation, and peripheral precocious puberty.
