  • Percentage of Patients With Gsα Mutation. [ Time Frame: Screening assessment (baseline) ] [ Designated as safety issue: No ]
    McCune-Albright Syndrome(MAS) is caused by an activating mutation in the gene coding for the stimulatory subunit of the G protein, Gsα. The altered Gsα causes autonomous activation of G-protein stimulated cAMP formation, which in the gonads, results in episodic uncontrolled sex steroid production and subsequent pubertal development. For patients who provided separate specific informed consent, the percentage of patients with a Gsα mutation at screening was assessed by molecular analysis.
