Purpose: Single-nucleotide polymorphism (SNP) in the promoter region of the IL-10 gene can increase susceptibility to tumor development. The current study aimed to explore the genotypic frequency of interleukin-10 (IL-10) rs1800896 polymorphism in newly diagnosed adult patients with acute lymphoblastic leukemia (ALL) and validate whether this SNP is a risk factor for adult ALL.
Patients And Methods: This case-control study was based on a subset of newly diagnosed 154 adult patients with ALL recruited from the Radiation and Isotope Center in Khartoum (RICK) and 154 healthy controls from the same geographical area. Genomic DNA was used for the genotyping of rs1800896 polymorphism through allele-specific polymerase chain reaction (PCR) assays.
Results: The genotypic frequencies of rs1800896 showed a statistically significant association of AG and AA genotypes with adult ALL (<0.001). Combined genotypes AG+GG vs AA also showed a positive association of rs1800896 with adult ALL (OR=4.89). The allelic frequencies of G and A did not show any significant difference in adult patients with ALL compared with the control group. AG rs1800896 genotype showed an increased risk of B and T ALL (OR=2.51 and 4.70, respectively). Age at diagnosis, gender, and immunophenotype (B vs T ALL) did not exhibit any association of rs1800896 with ALL in this patient group.
Conclusion: rs1800896 polymorphism is associated with an increased risk of ALL in adult patients irrespective of the age at diagnosis, gender, and immunophenotype of ALL.

Article Synopsis
- Infections from the dengue virus, Orthoflavivirus denguei, can show no symptoms or a range of clinical signs due to its complex interactions with viral and host factors.
- The study examined specific genetic variations (SNPs) in the interleukin-10 (IL-10) gene among 333 individuals in northeastern Brazil to see how they relate to symptomatic dengue.
- Findings revealed that certain genotypes and the G allele of the -1082 A/G SNP are associated with a higher risk of developing symptomatic dengue, particularly in contrast to those with asymptomatic infections.

Background: Periodontitis is a complex disease, and bacterial factors play a crucial role in its initiation. The contributions of genetic and epigenetic factors to the pathogenesis of periodontal disease are increasingly recognized. Single-nucleotide polymorphisms (SNPs) in various molecules, including cytokines, are of particular interest due to their established involvement in numerous diseases.

Background And Aims: Various inflammatory and immune cytokines play key roles in the progression of hepatitis B virus (HBV)-related liver cirrhosis (LC). This study explored the relationship between single nucleotide polymorphisms (SNPs) in cytokines with the combined effect of polymorphisms and gender-polymorphisms interaction and LC risk.
Methods: In this study, a case-control design was used, samples were selected from 45 patients with hepatitis B-related cirrhosis and 45 age-gender-matched chronic HBV-infected patients without cirrhosis attending the tumor hospital of Wuwei Academy of Medical Sciences.
