Fusion Gene: A Rare Case Report of Adult Myeloid/Lymphoid Neoplasm With Eosinophilia and Tyrosine Kinase Gene Fusions.

Myeloid/lymphoid neoplasms with eosinophilia and tyrosine kinase gene fusions (MLN-TK) represent rare hematological malignancies driven by pathological fusion genes involving tyrosine kinase genes. Among these, rearrangements of the gene, particularly the rearrangement, are frequently observed as pathogenic mutations. Conversely, instances of the fusion gene are rarely documented.
