Gene MAP2K1
Variant P124S
Impact List missense
Protein Effect unknown
Gene Variant Descriptions MAP2K1 P124S lies within the protein kinase domain of the Map2k1 protein (UniProt.org). P124S results in increased Erk1/2 phosphorylation and confers resistance to Mek and Braf inhibitors (PMID: 19915144, PMID: 22197931) and an Egfr antibody (PMID: 33322618) in culture, but has similar induction of cell proliferation and viability levels to wild-type Map2k1 in culture (PMID: 29533785), and therefore, its effect on Map2k1 protein function is unknown.

Filtering

  • Case insensitive filtering will display rows if any text in any cell matches the filter term
  • Use simple literal full or partial string matches
  • Separate multiple filter terms with a space. Any order may be used (i. e. a b c and c b a are equivalent )
  • Filtering will only apply to rows that are already loaded on the page. Filtering has no impact on query parameters.
  • Use quotes to match on a longer phrase with spaces (i.e. "mtor c1483f")

Sorting

  • Generally, the default sort order for tables is set to be first column ascending; however, specific tables may set a different default sort order.
  • Click on any column header arrows to sort by that column
  • Hold down the Shift key and click multiple columns to sort by more than one column. Be sure to set ascending or descending order for a given column before moving on to the next column.

MAP2K1 P124S colorectal cancer predicted - resistant Cetuximab + Irinotecan Case Reports/Case Series Actionable In a clinical case study, a patient with KRAS/NRAS-wild-type colorectal cancer who progressed on treatment with Erbitux (cetuximab) and Camptosar (irinotecan) was found through ctDNA testing to have acquired MAP2K1 P124S, and preclinical analysis of colorectal cancer cells expressing MAP2K1 P124S demonstrated increased Erk phosphorylation upon treatment with Erbitux (cetuximab) in culture (PMID: 33322618). 33322618
