Abstract Text

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.

ALK	G1123S	missense	unknown	ALK G1123S lies within the protein kinase domain of the Alk protein (UniProt.org). G1123S has been demonstrated to confer drug resistance in culture (PMID: 26134233, PMID: 21948233), but has not been biochemically characterized and therefore, its effect on Alk protein function is unknown (PubMed, Aug 2024).
