In addition, ZRSR2 mutations are occasionally associated with other hematological diseases, i.e., chronic myelomonocytic leukemia, refractory anemia with ringed sideroblasts, secondary acute myeloid leukemia, and blastic plasmacytoid dendritic cell neoplasm [15,16,17,18]. The gene discussed is ZRSR2; the disease is hematologic disorder.
