A Novel, Ruxolitinib‐Sensitive, CCDC6 :: JAK2 Fusion Gene in a Patient With Atypical, JAK2 Unmutated, Polycythemia Vera‐Like, Myeloproliferative Neoplasm

Year: 2025

Type: article

Abstract: In our study, we identified a novel, ruxolitinib-sensitive, CCDC6::JAK2 fusion gene as a driver of atypical JAK2-unmutated MPN with a polycythemic phenotype. The CCDC6::JAK2 chimeric protein retains the CCDC6 coiled-coil domain and the JAK2 kinase domain. Dimerization of chimeric proteins through coiled-coil domains promotes JAK2 autophosphorylation leading to constitutive activation of the JAK/STAT signaling pathway.
