CSF3R and chronic neutrophilic leukemia: Intriguingly, it was noted that not all patients in the CNL-like group carried mutant CSF3R (12 out of 26 with wild-type CSF3R, Table 3), which may change future disease subtyping and/or treatment strategy for neutrophilic leukemia patients with a CNL-like expression signature instead of CSF3R mutations.
