Another study in CK‐AML patients revealed that when stratifying patients into “typical CK”, defined as CK containing high‐risk abnormalities in 5q, 7q, and/or 17p, and “atypical CK”, defined as CK without such abnormalities, CK‐AML patients with atypical CK had a significantly higher rate of PHF6 mutation and favorable outcomes.59 The gene discussed is PHF6; the disease is acute myeloid leukemia.
