Gene Symbol FGFR1
Synonyms bFGF-R-1 | BFGFR | CD331 | CEK | ECCL | FGFBR | FGFR-1 | FLG | FLT-2 | FLT2 | HBGFR | HH2 | HRTFDS | KAL2 | N-SAM | OGD
Gene Description FGFR1, fibroblast growth factor receptor 1, is a receptor tyrosine kinase activated upon binding of the FGF ligand, which activates RAS-MAPK and PI3K-AKT pathways (PMID: 22508544). Altered function of Fgfr1 may lead to increased cell proliferation and decreased apoptosis (PMID: 22508544) and amplification and/or overexpression has been identified in colorectal cancer (PMID: 30181810), gastric cancer (PMID: 29976636), and breast cancer (PMID: 30119151).


  • 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")


  • 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 FGFR1 act mut indicates that this variant results in a gain of function in the Fgfr1 protein. However, the specific amino acid change has not been identified.
fusion fusion unknown FGFR1 fusion indicates a fusion of the FGFR1 gene, but the fusion partner is unknown.
inact mut unknown loss of function FGFR1 inact mut indicates that this variant results in a loss of function of the Fgfr1 protein. However, the specific amino acid change has not been identified.
mutant unknown unknown FGFR1 mutant indicates an unspecified mutation in the FGFR1 gene.
N193fs frameshift loss of function - predicted FGFR1 N193fs results in a change in the amino acid sequence of the Fgfr1 protein beginning at aa 193 of 822, likely resulting in premature truncation of the functional protein ( N193fs results in decreased proliferation relative to wild-type Fgfr1 in a competition assay and decreased transformation activity in cultured cells (PMID: 34272467), and therefore, is predicted to lead to a loss of Fgfr1 protein function.
rearrange unknown unknown FGFR1 rearrangement indicates an unspecified rearrangement of the FGFR1 gene.
