  • 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"


  • 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.

RB1 K240Sfs*22 TP53 R248W Her2-receptor negative breast cancer predicted - resistant Fulvestrant + Palbociclib Case Reports/Case Series Actionable In a clinical case study, RB1 K240Sfs*22 and TP53 R248W were identified in the circulating tumor DNA of a patient with estrogen receptor positive, progesterone receptor positive, and Erbb2 (Her2)-negative, invasive ductal carcinoma at the time of disease progression after 5 months of Ibrance (palbociclib) and Faslodex (fulvestrant) combination treatment (PMID: 29236940). 29236940
