    Abstract
    Objectives: This study was aimed to evaluate the disease association of each killer-cell immunoglobulin-like receptor (KIR) gene and their known human leukocyte antigen (HLA) ligands (HLA-C and -Bw4) as well as KIR haplotypes and KIR-HLA interactions in Lur population of west of Iran.
    Methods: In this case-control study, 50 cases with colorectal cancer and 100 healthy controls were taken. The genomic DNA was extracted and polymerase chain reaction with sequence specific primers (PCR-SSP) was used to genotyping the samples. Statistical analysis was done using 2 by 2 tables. In order to compare the results with other previous studies, funnel plot and cluster analysis was used.
    Results: Among the single gene analyses, only the association of KIR2DS5 was statistically significant (Pearson chi-square P =0.0206; Yate's corrected chi-square P =0.0323; OR =2.25 [1.12-4.49 95% CI]). No significant association was observed for neither KIR nor HLA genotypes. Among the KIR-HLA interactions, no significant association was observed as well.
    Conclusion: The results of this paper supported the results of previous studies as well as the rationale existing behind the tumor biology. The ligand of KIR2DS5 should be discovered and evaluated in future.
