Abstract:
We conducted genotypic analyses of interleukin-10 (IL-10) (-1082 G/A; GG, GA, AA) and interleukin-28B
(CC, CT, TT) genes polymorphisms in acute lymphoblastic leukemia (ALL) pediatric patients in descriptive study to evaluate the prevalence of these mutations. In amplification refractory mutation system-PCR (ARMS-PCR), one reaction was carried out for each patient’s DNA sample. For IL-28B gene, two forward and two reverse primers specific for Callele and T-allele were used separately. For human IL-10 gene, two different forward primers specific for A and G alleles were used in combination with common reverse primer. IL-10 gene promoter showed highest frequency (n=29, 58%) of heterozygous (GA) allele, while genotypic analysis of IL-28B gene showed highest frequency (n=28, 56%) of homozygous (CC) allele. The IL-10 (AA) genotype related to its protein’s less production in body which may be associated with the least survival of ALL’s patients, while IL-28b (CT and TT) genotypes may be associated with less IFNλ3 levels and less life expectancy.
