Abstract Text

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 E765G missense unknown FGFR1 E765G lies within the protein kinase domain of the Fgfr1 protein (UniProt.org). E765G has been identified in the scientific literature (PMID: 34250399), but has not been biochemically characterized and therefore, its effect on Fgfr1 protein function is unknown (PubMed, May 2025).
FGFR1 K687E missense unknown FGFR1 K687E (corresponds to K656E in the canonical isoform) lies within the protein kinase domain of the Fgfr1 protein (UniProt.org). K687E has been identified in the scientific literature (PMID: 32622884, PMID: 34250399, PMID: 35952322), but has not been biochemically characterized and therefore, its effect on Fgfr1 protein function is unknown (PubMed, May 2025).
FGFR1 V592M missense unknown FGFR1 V592M (corresponds to V561M in the canonical isoform) lies within the protein kinase domain of the Fgfr1 protein (UniProt.org). V592M has been identified in the scientific literature (PMID: 34250399), but has not been biochemically characterized and therefore, its effect on Fgfr1 protein function is unknown (PubMed, Jun 2025).

FGFR1 V592M FGFR1 K687E pilomyxoid astrocytoma predicted - sensitive Zoligratinib Case Reports/Case Series Actionable In a clinical case study, Debio 1347 treatment resulted in a significant clinical improvement and sustained stable disease at 14 months with a 12.2% maximal tumor reduction in a pediatric patient with optic pathway pilomyxoid astrocytoma harboring FGFR1 V592M and FGFR1 K687E (PMID: 34250399). 34250399
FGFR1 V592M FGFR1 K687E glioblastoma predicted - sensitive Zoligratinib Case Reports/Case Series Actionable In a clinical case study, Debio 1347 treatment resulted in a near complete response with a 96.3% maximal tumor reduction after 2 months of therapy in a pediatric patient with spinal cord glioblastoma harboring FGFR1 V592M and FGFR1 K687E, and the response was maintained for 11 months (PMID: 34250399). 34250399
