JAK3(A572V), JAK3(V722I), and JAK3(P132T) each transform Ba/F3 cells to factor-independent growth, and JAK3(A572V) confers features of megakaryoblastic leukemia in a murine model.

Using this screen, we identified interleukin-2 gamma receptor (IL2Rγ) as a critical growth determinant for a JAK3(A572V) mutation-positive acute myeloid leukemia cell line.
Although known activating substitutions were observed in rare cases of acute myeloid leukemia (AML) (V722I [2/134] or P132T [1/119]), all samples were wild-type (WT) for the oncogenic A572V (119/119).
