| Protein Effect | loss of function - predicted |
| Gene Variant Descriptions | MAP2K1 L118D lies within the protein kinase domain of the Map2k1 protein (UniProt.org). L118D is predicted to confer a loss of function to the Map2k1 protein as demonstrated by decreased basal Map2k1 kinase activity in an in vitro assay and is associated with resistance to Mek inhibition (PMID: 12370306). |
