| Protein Effect | gain of function |
| Gene Variant Descriptions | JAK2 V625F lies within the protein kinase domain 1 of the Jak2 protein (UniProt.org). V625F confers a gain of function to the Jak2 protein as demonstrated by cytokine-independent JAK2-STAT5 signaling and hypersensitivity to Tpo and Interleukin-3 as indicated by increased cell viability in culture (PMID: 26423830). |
