Gene JAK2
Variant L583_A586delinsS
Impact List indel
Protein Effect gain of function
Gene Variant Descriptions JAK2 L583_A586delinsS results in a deletion of four amino acids from amino acids 583 to 586 of the Jak2 protein, combined with the insertion of a serine (S) at the same site (UniProt.org). L583_A586delinsS confers a gain of function to the Jak2 protein as indicated by ligand-independent cell growth and activation of Stat5, Erk1/2, and beta common chain-associated cytokine receptor signaling, and has been demonstrated to confer resistance to Jak2 inhibitors in cultured cells (PMID: 31697804).
Associated Drug Resistance Y

Filtering

  • Case insensitive filtering will display rows where any text in any cell matches the filter term
  • Simple literal full or partial string matches
  • Separate multiple filter terms with a spaces, order doesn't matter (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 a longer phrase which contains spaces "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.
