Tóm tắt:

Primary myelofibrosis is the severe form of myeloproliferative neoplasms that causes scar tissue in the bone marrow, leading to low production of blood cells and thus, life span shortening. Besides the most common variant JAK2 V617F, the association between these disorders with other variants in the JAK2 gene, especially the exon 12 variants have been poorly studied. In our research, the JAK2 exon 12 variants were detected by amplification and sequencing from genomic samples of five cases with V617F-negative primary myelofibrosis.
