  • 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")


  • 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.

BRAF V600E MAP2K1 K57T hairy cell leukemia predicted - resistant Vemurafenib Case Reports/Case Series Actionable In a clinical case study, a single patient with hairy cell leukemia harboring BRAF V600E, who relapsed after a 38 week remission in response to Zelboraf (vemurafenib) treatment, was found to have acquired multiple clones with Mek/Erk activating mutations, of which the MAP2K1 K57T clone became dominant (PMID: 30341394). 30341394
