[Research progress on the pathogenic mechanisms, diagnosis and treatment of McCune-Albright syndrome].

McCune-Albright syndrome is a rare chimeric disorder due to mutations in the postzygotic GNAS gene. It belongs to the group of guanine nucleotide-binding protein diseases, affecting a wide range of individuals. It is characterized by fibrous dysplasia, café-au-lait skin macules, and precocious puberty with other variable clinical manifestations. At present, there are difficulties in the molecular diagnosis of McCune-Albright syndrome, and there is a lack of effective clinical treatments to halt or reverse the course and regression of the disease. This article summarizes the clinical manifestations, diagnosis, pathogenic molecular mechanisms, treatment and relevant fertility guidelines of McCune-Albright syndrome, with a view to further research and therapy of McCune-Albright syndrome.
