Nevertheless, compared to BCP-ALL ‘other’ cases not classified as DUX4 rearranged, an overexpression of DUX4 target genes such as PCDH17 (logFC 7.51, P-value < 0.0001), PDGFRA (logFC 5.65, P-value < 0.0001), and AGAP1 (logFC 5.52, P-value < 0.0001) could be observed. The gene discussed is PCDH17; the disease is acute lymphoblastic leukemia.
