Blood counts for most normal leukocyte subsets (i.e., neutrophils, eosinophils, dendritic cells, Tγδ+, and CD56+ NK cells) were significantly reduced (vs. age-matched HD) among T/NK-LGLL, particularly among STAT3-mutated T/NK-LGLL patients (Table 2). The gene discussed is ABCA1; the disease is T-cell large granular lymphocyte leukemia.
