Gene Variant Descriptions PBRM1 loss indicates loss of the PBRM1 gene, mRNA, and protein.
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.

PBRM1 loss melanoma sensitive unspecified CTLA4 antibody + unspecified PD-1 antibody Preclinical - Cell line xenograft Actionable In a preclinical study, knocking-out PBRM1 in melanoma cells sensitized cells to immune therapy consisted of anti-CTLA4 and anti-PD-1 antibodies in culture and in cell line xenograft models, potentially due to increased sensitivity to T cell-mediated cytotoxicity and a favorable tumor microenvironment (PMID: 29301958). 29301958

PBRM1 inact mut melanoma not predictive unspecified immune checkpoint inhibitor Clinical Study - Cohort Actionable In a retrospective analysis, somatic loss-of-function mutations in the genes of the mSWI/SNF complex, including PBRM1, did not correlate with improved survival in 2 separate cohorts of patients with melanoma treated with systemic immune checkpoint inhibitors, with adjusted HRs for overall survival of 1.70 (p=0.192, n=86) and 1.02 (p=0.939, n=192), respectively (PMID: 32321774). 32321774
