Variant | P306H |
Impact List | missense |
Protein Effect | gain of function |
Gene Variant Descriptions | MAP2K1 P306H lies within the protein kinase domain of the Map2k1 protein (UniProt.org). P306H confers a gain of function to the Map2k1 protein as indicated by increased phosphorylation of Erk1/2 and modest transformation activity in culture (PMID: 22327936). |

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... |
