MKX and acute lymphoblastic leukemia: Although not in frame, the reported fusion gene MLLT10::MKX in pediatric BCP-ALL may indicate an oncogenic role for MKX in this type of B-cell malignancy as well [41], even though MM is B-cell-derived and rather originates from GC-B-cells [55], contrasting with pro/pre-B-cell originating BCP-ALL.
