Fibrous Dysplasia/McCune-Albright Syndrome: A Rare, Mosaic

  1. Fibrous dysplasia/McCune-Albright syndrome (FD/MAS) is a rare disorder of striking complexity. Somatic gain-of-function mutations lead to mosaic activation of Gα s, resulting in disease that may involve any part of the skeleton, and may be variably associated with cutaneous, endocrine, and other extraskeletal features
  2. Fibrous dysplasia/McCune-Albright syndrome (FD/MAS), the result of an early embryonic postzygotic somatic activating pathogenic variant in GNAS (encoding the cAMP pathway-associated G-protein, Gsα), is characterized by involvement of the skin, skeleton, and certain endocrine organs. However, because Gsα signaling is ubiquitous, additional tissues may be affected
  3. McCune-Albright syndrome is a rare genetic disordered originally recognized by the triad of polyostotic fibrous dysplasia, precocious puberty, and café-au-lait spots. A variety of endocrine disorders, including hyperthyroidism, acromegaly, phosphate wasting, and Cushing syndrome are now considered a
  4. McCune Albright syndrome (MAS) is a clinical association of endocrine and nonendocrine anomalies caused by postzygotic mutation of the GNAS1 gene, leading to somatic activation of the stimulatory α-subunit of G protein (Gsα)
  5. McCune-Albright syndrome (MAS) is a disorder that affects the skin, skeleton, and certain endocrine organs (hormone -producing tissues). Cafe-au-lait spots of the skin are common and are usually the first apparent sign of MAS. The main skeletal feature is fibrous dysplasia, which ranges in severity and can cause various complications
  6. McCune-Albright syndrome (MAS) is a genetic disease that affects the bones, skin, and the production of certain hormones, including those that affect growth and the onset of puberty. The NICHD supports research to understand the genetic causes of MAS, how it affects the body, and treatments for MAS and related conditions
