Abstract
Objective To investigate the correlation of killer immunoglobulin-like receptors（KIR）gene polymorphism with bone marrow failure syndromes（BMFS）. Methods SSP-PCR was used to examine the genotypic makeup of KIR in patients with aplastic anemia（ AA）, myelodysplatic syndrome （MDS） and healthy controls in our department. Results All the 16 KIR genes which had been prescribed were identified. The frequencies of KIR-2DS1, 2DS2, 2DS3, 2DS5 and 3DS1 genes were showed increased in patients with AA, MDS than in healthy controls. The patients with AA had lower frequency of KIR-2DS5 than the patients with MDS. Conclusion The increased frequencies of these activated KiRs in patients with MDS and AA suggest that the abnormal immunogenetic might be related to the pathogenesis of BMFS. Key words: Killer cell immunoglobin-like receptor Polymorphism Bone marrow failure syndromes
