Diagnostic, Oncogenic evidence:
Diagnostic: The abstract states that mutations in FGFR1 have been associated with Hartsfield syndrome, indicating that these mutations are used to define or classify this specific disease. This association highlights the role of FGFR1 mutations in the context of a clinically distinct syndrome, fulfilling the criteria for diagnostic evidence.
Oncogenic: The abstract mentions that five distinct mutations in the FGFR1 kinase domain behave as dominant-negative mutations in zebrafish over-expression assays, suggesting that these mutations contribute to tumor development or progression. This evidence supports the classification of these variants as oncogenic due to their functional impact in a model organism.
