DNA NGS revealed a pathogenic TP53 mutation but was negative for mutations in other genes including KIT, JAK2, CALR, and MPL.<h4>Conclusions</h4>Given that PDGFRA fusions with novel fusion partners may respond to tyrosine kinase inhibitor therapy, partner agnostic testing methods should be considered either up front or as reflex testing in patients with myeloid and/or lymphoid neoplasms with blood, bone marrow, or tissue eosinophilia. This evidence concerns the gene KIT and Increased total eosinophil count.
