Gene KIT
Variant Y570_Y578del
Impact List deletion
Protein Effect gain of function - predicted
Gene Variant Descriptions KIT Y570_Y578del results in the deletion of nine amino acids in the juxtamembrane domain (exon 11) of the Kit protein from amino acids 570 to 578 (PMID: 16226710). Y570_Y578del has not been characterized, however similar Kit exon 11 deletions are activating (PMID: 9438854, PMID: 15365079), and therefore, is predicted to lead to a gain of Kit protein function.

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.
