McCune–Albright syndrome

McCune–Albright syndrome is a complex genetic disorder affecting the bone, skin and endocrine systems. It is a mosaic disease arising from somatic activating mutations in GNAS, which encodes the alpha-subunit of the Gs G protein-coupled receptor. These mutations lead to constitutive receptor activation. McCune–Albright syndrome is a complex genetic disorder affecting the bone, skin and endocrine systems.
