Within the 3 other immunophenotypes of CD8+ T-LGL leukemia any other case did not show neutropenia but one (1/27, 3.7%; Figure 3A), that was the only STAT3 mutated case out of the most common immunophenotypic signature (CD16+/CD56-) and it belonged to CD16-/CD56-/CD57+ subset. Here, B3GAT1 is linked to neutropenia.
