Gene JAK2
Variant inact mut
Impact List unknown
Protein Effect loss of function
Gene Variant Descriptions JAK2 inact mut indicates that this variant results in a loss of function of the Jak2 protein. However, the specific amino acid change has not been identified.
Associated Drug Resistance

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.

JAK2 inact mut melanoma predicted - resistant Pembrolizumab Case Reports/Case Series Actionable In a clinical study, a melanoma patient treated with Keytruda (pembrolizumab) initially demonstrated a partial response, however, post 734 days developed disease progression due to a splice site mutation in JAK2, which resulted in an intron inclusion and an early stop codon, leading to a loss of protein expression (PMID: 27433843). 27433843
JAK2 LOH JAK2 inact mut melanoma predicted - sensitive VSV-delta51 Preclinical - Patient cell culture Actionable In a preclinical study, a melanoma patient-derived cell line harboring an inactivating JAK2 mutation and JAK2 loss of heterozygosity resulted in sensitivity to treatment with an oncolytic virus, VSV-delta51, in culture (PMID: 33593882). 33593882
JAK2 LOH JAK2 inact mut melanoma predicted - sensitive HSV1-dICP0 Preclinical - Patient cell culture Actionable In a preclinical study, a melanoma patient-derived cell line harboring an inactivating JAK2 mutation and JAK2 loss of heterozygosity resulted in sensitivity to treatment with an oncolytic virus, HSV-dICP0, in culture (PMID: 33593882). 33593882
