A database of published Gs-alpha germline mutations was constructed by searching the NCBI PubMed literature database for articles, using the keywords “mutation” combined with either “GNAS”, “Gs-alpha”, “Albright hereditary osteodystrophy”, “pseudohypoparathyroidism” or “progressive osseous heteroplasia”. The gene discussed is GNAS; the disease is pseudohypoparathyroidism type 1A.
