MAP2K2 (P36507) variants and mutations

MAP2K2 (also known as P36507) is a human protein-coding gene encoding a dual specificity mitogen-activated protein kinase kinase 2 protein. It works with MEK1 to activate ERK signaling downstream of RAS and RAF. Germline activating variants can cause cardio-facio-cutaneous syndrome, while acquired activation can support oncogenic MAPK signaling and drug resistance. This analysis covers 1,648 MAP2K2 variants and mutations. Of these, 51% have computational variant effect predictions. Disease context includes cardiofaciocutaneous syndrome, melanoma, and cancer. Example MAP2K2 variants include A3S, A3T, and A3V.
