Whereas the Olivieri screens were performed in the same cell line (hTERT-immortalized RPE-1 TP53 knockout), our genome-wide screens were performed in HAP1 cells, a near-haploid cell line derived from the KBM7 chronic myelogenous leukemia (CML) cell line. Here, TP53 is linked to chronic myelogenous leukemia, BCR-ABL1 positive.
