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.

IDH2 R172W	acute myeloid leukemia	sensitive	IDH2 Inhibitor	Enasidenib	FDA approved - On Companion Diagnostic	Actionable	In a Phase I/II trial that supported FDA approval, Idhifa (enasidenib) treatment resulted in an overall response rate of 40.3% (71/176) with a median response duration of 5.8 months, complete remission in 19.3% (34/176), and stable disease in 48.3% (85/176) of acute myeloid leukemia patients harboring IDH2 mutations (PMID: 28588020; NCT01915498) and IDH2 R172W is on the companion diagnostic.	28588020 detail... detail...
