We identified 30 genes demonstrating methylation frequencies of \u226525% in childhood ALL, nine genes showed significantly different methylation frequencies in B vs T-ALL. For majority of the genes expression could be restored in methylated leukemia lines after treatment with 5-azaDC. Forty-four percent of the genes represent targets of the polycomb complex. In chronic myeloid leukemia (CML) two of the genes, (\n                      <jats:italic>TFAP2A<\/jats:italic>\n                      and\n                      <jats:italic>EBF2)<\/jats:italic>\n                      , demonstrated increased methylation in blast crisis compared to chronic phase (P &lt; 0.05).
