In adrenocortical carcinoma (ACC, T = 77, N = 128), acute myeloid leukaemia (LAML, T = 173, N = 70), and skin cutaneous melanoma (SKCM, T = 469, N = 813), the expression of PPP1R14B was lower than that in normal tissues, and the differences were statistically significant (p < 0.05). Here, PPP1R14B is linked to acute myeloid leukemia.
