The patient was found with karyotype 46, XX [20] (Figure 1D) We did the PML-RARalpha fusion gene test (using polymerase chain reaction, PCR and FISH methods) once we suspected APL of the patient on day 1, and re-checked the results of PML-RARalpha in two different medical laboratory institutions. This evidence concerns the gene PML and acute promyelocytic leukemia.
