Gene FGFR1
Variant M563T
Impact List missense
Protein Effect unknown
Gene Variant Descriptions FGFR1 M563T (corresponds to M532T in the canonical isoform) lies within the protein kinase domain of the Fgfr1 protein (UniProt.org). M563T has been identified in the scientific literature (PMID: 34551969), but has not been biochemically characterized and therefore, its effect on Fgfr1 protein function is unknown (PubMed, May 2025).

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.

FGFR1 M563T intrahepatic cholangiocarcinoma predicted - sensitive Futibatinib Case Reports/Case Series Actionable In a Phase I trial, Lytgobi (futibatinib) treatment led to an overall objective response rate of 15.8% (3/19, 3 partial responses) and a disease control rate of 47.4% (9/19), with stable disease in 6, in patients with urothelial cancer harboring an FGFR3 mutation or FGFR1 mutation, including a partial response with a progression-free survival of 6.8 mo and a duration of response of 5.6 mo in a urothelial cancer patient harboring FGFR1 M563T and amplifications in FGF3 and FGF19 (PMID: 34551969; NCT02052778). 34551969
