Association of Two ARID5B Gene Variant Single Nucleotide Polymorphisms with Acute Lymphoblastic Leukemia in the Egyptian Population

BACKGROUND: ARID5B SNPs have been linked to ALL in many research studies in which it was identified as a risk factor. From this context, we had great interest to investigate the relationship between ARID5B rs4948488 and ARID5B rs2893881 genotypes and ALL susceptibility and relapse in this study. MATERIALS AND METHODS: Peripheral blood mononuclear cells were analyzed for ARID5B rs4948488 and rs2893881 gene polymorphisms by real-time quantitative polymerase chain reaction in 80 ALL patients and 80 controls. RESULTS: Our results showed that the C/C genotype of ARID5B rs4948488 and A/G genotype and G-allele of rs2893881 were linked to higher ALL incidence. Regarding the relapse of ALL, rs4948488 C/C genotype and C-alleles were significantly associated with relapse of ALL. Meanwhile, rs4948488 C/C genotype and rs2893881 A/A genotype and A-allele are associated with T-ALL, while rs2893881 A/G genotype and G-allele are associated with B-ALL. CONCLUSION: The results of our study suggested that ARID5B rs4948488 and rs2893881 SNPs might be used risk factors for genetic susceptibility for B-ALL and T-ALL, and that ARID5B s4948488 is related to relapse in ALL patients.
