Abstract 1697 There is increasing evidence for the role of KIR genetics in predicting outcome of haematological malignancies. We recently showed that donor (but not recipient) KIR genes 2DS1, 3DS1 and 2DL5a are associated with significantly less relapse in AML patients following matched sibling allogeneic stem cell transplantation. Interestingly, this effect was not seen in patients with AML secondary to MDS but only in de novo AML.1 To explore whether outcome of non-transplant treatment for AML might be affected by KIR genetics we performed KIR genotyping on the DNA sample archive from the Medical Research Council UK AML 10 and 15 trials. All patients underwent four courses of chemotherapy according to MRC protocols. KIR genotyping was performed using Qiagen SSP PCR KIR genotyping kits as previously described.1 We measured KIR gene frequencies in AML samples obtained at diagnosis from 469 de novo AML, and 38 secondary AML and compared the gene distribution with that of a normal control population of 246 individuals. To allow for multiple comparisons, significance was set at p
