    Abstract:
    OBJECTIVE: This study seeks to elucidate the association between HLA-A, HLA-B, and HLA-DRB1 alleles and their relative risk contributions to ALL within an Iranian cohort. METHODS: Utilizing a robust case-control design, this research involved 71 ALL patients and 71 age and sex-matched healthy individuals. Genotyping of specified HLA alleles was performed using the advanced PCR-SSP technique. RESULTS: Our findings reveal a marked increase in the prevalence of the HLA-DRB1*04 allele among patients diagnosed with ALL compared to the control group (P<0.027). Conversely, the alleles HLA-A*26 (P=0.025), HLA-A*33 (P=0.020), and HLA-DRB1*03 (P=0.035) were observed at significantly reduced frequencies within the patient population. CONCLUSION: Our findings highlight HLA-DRB1*04 as a potential genetic marker for increased susceptibility to ALL, while HLA-A*26, HLA-A*33, and HLA-DRB1*03 emerge as protective factors.
