Protein Effect | gain of function - predicted |
Gene Variant Descriptions | JAK2 R975G lies within protein kinase domain 2 of the Jak2 protein (UniProt.org). R975G results in increased Jak2, Stat5, Akt, and Erk phosphorylation, and has also been described as a secondary drug resistance mutation in the context of ETV6-JAK2 (PMID: 22916261), and therefore, is predicted to lead to a gain of Jak2 protein function. |
