This GNAS mutation causes constitutive activation of the G-protein complex and activates adenylate cyclase to produce cyclic-AMP (cAMP) that can activate oncogenic pathways. The frequency of GNAS mutation in non-small cell carcinoma of the lung cases is relatively low (<5%) and its significance remains to be fully elucidated.
