The signaling cascade involving these genes, that is, BRAF-MEK1/2 (MAP2K1/2)-ERK1/2 (MAPK1/3), is part of the MAPK signaling pathway, which is involved in cell proliferation, differentiation, and migration [40] and was recently found to be dysregulated in MG [41]. Here, MAPK1 is linked to myasthenia gravis.
