Other than WT1 and proteinase 3, the receptor for hyaluronic-acid-mediated motility (RHAMM/CD168) [13], human telomerase reverse transcriptase (hTERT) [14], preferentially expressed antigen in melanoma (PRAME) [15, 16], and Aurora-A [17] have been reported as potentially useful AML-associated antigens. This evidence concerns the gene WT1 and acute myeloid leukemia.
