Fig. 3From: Missense mutation of NRAS is associated with malignant progression in neurocutaneous melanosis Sharing of somatic mutation profiles defined by multiregional ddPCR. GNAQ and S1PR3 showed similar results, with numerous mutant droplets detected in brain and abdominal tumors. On the other hand, NRAS mutation was only detected in the abdominal tumor.
