PCR amplification of ST3GAL1-NDRG1 (5 spanning reads in ALL 542-PA), MCM4-PRKDC (3 spanning reads in ALL 542-RD), PQLC1-CTDP1 (6 spanning reads in AML 800-RD), NCL-NR4A1 (3 spanning reads in AML 800-PA) and HBB-B2M (8 spanning reads in ALL 542-RD) failed to detect the fusion gene, except HBB-B2M in ALL 542-RD. This evidence concerns the gene NUCLEOLIN and acute myeloid leukemia.
