Profile Name FBXW7 loss
Gene Variant Detail

FBXW7 loss (loss of function)

Relevant Treatment Approaches mTORC1 Inhibitor

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.

FBXW7 loss colon cancer sensitive mTORC1 Inhibitor Sirolimus Preclinical Actionable In a preclinical study, Rapamune (sirolimus) inhibited epithelial-mesenchymal transition, motility, and invasiveness in colon cancer cells lacking FBXW7 in culture (PMID: 23558291) 23558291
FBXW7 loss melanoma predicted - resistant unspecified PD-1 antibody Preclinical Actionable In a preclinical study, an FBXW7-deficient melanoma cell line in a mouse model was resistant to treatment with an unspecified PD-1 antibody, demonstrating increased tumor volume and poor survival compared to models with wild-type FBXW7 (PMID: 32371478). 32371478
FBXW7 loss colon cancer predicted - resistant unspecified PD-1 antibody Preclinical Actionable In a preclinical study, an FBXW7-deficient colon cancer cell line in a mouse model was resistant to treatment with an unspecified PD-1 antibody, demonstrating poor survival and decreased inhibition of tumor growth compared to models with wild-type FBXW7 (PMID: 32371478). 32371478
