LPIN1 and acute myeloid leukemia: To further corroborate this observation, we compared CHKA and LPIN1 mRNA co‐expression in the Leucegene AML cohort and found that indeed complex karyotype AML with TP53 mutation, but not with TP53 wild type, expressed the highest CHKA levels reaching the high levels detected in CB CD34+ cells (Figure 6E).
