Impact List | missense |
Protein Effect | gain of function |
Gene Variant Descriptions | MAP2K1 V211D lies within the protein kinase domain of the Map2k1 protein (UniProt.org). V211D confers a gain of function to Map2k1, as demonstrated by increased phosphorylation of Mek and Erk in cultured cells and in vitro kinase assays, and also demonstrates Braf and Mek inhibitor resistance (PMID: 29753091, PMID: 19915144, PMID: 31227518). |

MAP2K1 mutant | Erdheim-Chester disease | sensitive | Trametinib | Guideline | Actionable | Mekinist (trametinib) is included in guidelines as first-line or subsequent-line therapy for patients with Erdheim-Chester disease harboring mutations in the MAPK pathway such as ARAF, NRAS, KRAS, MAP2K1/2, PIK3CA, or with no detectable mutations, or for whom testing is not available (NCCN.org). | detail... |
MAP2K1 mutant | Erdheim-Chester disease | sensitive | Cobimetinib | Guideline | Actionable | Cotellic (cobimetinib) is included in guidelines as preferred first-line or subsequent-line therapy for patients with Erdheim-Chester disease harboring mutations in the MAPK pathway such as ARAF, NRAS, KRAS, MAP2K1/2, PIK3CA, or with no detectable mutations, or for whom testing is not available (NCCN.org). | detail... |
