Gene Symbol CSF1R
Synonyms BANDDOS | C-FMS | CD115 | CSF-1R | CSFR | FIM2 | FMS | HDLS | HDLS1 | M-CSF-R
Gene Description CSF1R, colony stimulating factor 1 receptor, is a tyrosine kinase and receptor for CSF1 and IL34, which upon ligand binding activates PI3K-AKT-mTOR, RAS-RAF-MEK-ERK and STAT signaling pathways (PMID: 22186992). CSF1R is expressed by tumor-associated macrophages to induce tumor promotion (PMID: 30065206) and therefore, a number of therapies to block Csf1r are under development (PMID: 28716061), and Csf1r activating mutations have been reported in histiocytic neoplasms (PMID: 31768065).


  • 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"


  • 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 CSF1R act mut indicates that this variant results in a gain of function in the Csf1r protein. However, the specific amino acid change has not been identified.
fusion fusion unknown CSF1R fusion indicates a fusion of the CSF1R gene, but the fusion partner is unknown.
mutant unknown unknown CSF1R mutant indicates an unspecified mutation in the CSF1R gene.
rearrange unknown unknown CSF1R rearrange indicates an unspecified rearrangement of the CSF1R gene.
