TP53 and acute myeloid leukemia: The atypical chemokine surface receptor C-C motif chemokine receptor-like 2 (CCRL2) is overexpressed in MDS and secondary AML (sAML) compared to healthy hematopoietic cells and we recently found that TP53-mutated MDS/AML and AML with erythroid features express the highest levels of this receptor across MDS/AML subtypes.
