We hypothesized that genetic variants play a role in the regulation of the transcription of these genes. We studied leukoblasts from 82 patients with acute myeloid leukemia and observed various extent and frequency of differential allelic expression in the CDA, DCK, NT5C2, NT5C3, and TP53 genes. Our attempts to identify the causative regulatory single nucleotide polymorphisms by a bioinformatics approach did not succeed. However, our results indicate that genetic variations are at least in part responsible for the differences in overall expression levels of these genes.
