Expression of CD244 and EAT-2 in patients with ALL was significantly lower than the control group (p = 0.0225 and p = 0.0375, respectively), while their expression was not significantly different between AML patients and the control group (p = 0.7785 and p = 0.5670; Fig. 1A and 1B). Here, SH2D1B is linked to acute myeloid leukemia.
