Gene Symbol ERBB4
Synonyms ALS19 | HER4 | p180erbB4
Gene Description ERBB4, erb-b2 receptor tyrosine kinase 4, encodes HER4, an ERBB family member that plays a role in cell survival and differentiation (PMID: 12648466). ERBB4 activating mutations are frequent in melanoma and have been demonstrated in lung adenocarcinoma (PMID: 19718025, PMID: 26050618).

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.

Variant Impact Protein Effect Variant Description Associated with drug Resistance
act mut unknown gain of function ERBB4 (HER4) act mut indicates that this variant results in a gain of function in the Erbb4 (Her4) protein. However, the specific amino acid change has not been identified.
inact mut unknown loss of function ERBB4 inact mut indicates that this variant results in a loss of function of the Erbb4 protein. However, the specific amino acid change has not been identified.
mutant unknown unknown ERBB4 mutant indicates an unspecified mutation in the ERBB4 gene.
T480fs frameshift loss of function - predicted ERBB4 T480fs results in a change in the amino acid sequence of the Erbb4 protein beginning at aa 480 of 1308, likely resulting in premature truncation of the functional protein (UniProt.org). Due to the loss of all known functional domains (UniProt.org), T480fs is predicted to lead to a loss of Erbb4 function.
