| Protein Effect | unknown |
| Gene Variant Descriptions | JAK2 E1028K lies within protein kinase domain 2 of the Jak2 protein (UniProt.org). E1028K is transforming in combination with JAK2 V617F in culture (PMID: 39091915), but has not been individually characterized and therefore, its effect on Jak2 protein function is unknown. |
