Gene ERBB2
Variant V842I
Impact List missense
Protein Effect unknown
Gene Variant Descriptions ERBB2 (HER2) V842I lies within the protein kinase domain of the Erbb2 (Her2) protein (UniProt.org). V842I confers resistance to selected tyrosine kinase inhibitors (PMID: 31588020), results in increased Erbb2 (Her2) activity, downstream pathway activation, and transformation of cultured cells (PMID: 23220880, PMID: 31588020), however, in another study, demonstrates similar cell proliferation and viability levels to wild-type Erbb2 (Her2) in two different cell lines (PMID: 29533785), and therefore, its effect on Erbb2 (Her2) protein function is unknown.

Filtering

  • 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"

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.
