Abstract: BACKGROUND: Tumor necrosis factor-α (TNFα) is a crucial physiologic regulator of immune responses, and several disorders have been associated with its dysregulation. OBJECTIVE: This study aimed to understand TNFα gene expression in adult patients with liver and pancreas disorders and examine the impact of TNFα-238 genotypes on this population. METHODS: At the Ibn Al-Baladi Hospital in Baghdad, blood samples were collected from forty patients who were diagnosed with beta thalassemia together with pancreatic disease, forty patients who were diagnosed with thalassemia together with liver disorder, and forty patients who were diagnosed with thalassemia without pancreas or liver disorder. For the purpose of establishing a control group, forty samples were collected from persons who were of the same age and gender and seemed to be in good health. All of these individuals were deemed to be older than 18 years old. Through the utilization of real-time polymerase chain reaction (PCR), the level of TNF-α gene expression was investigated and assessed. The T-ARMS-PCR method was performed for detection and genotyping of TNFα-238 in thalassemia patients and healthy control samples. RESULTS: The result showed that TNF α gene expression assessment showed that group B (thalassemia patients with liver disorder) had higher folding than other groups while the lowest gene expression was in group D (as control group). Furthermore, the relationship between TNFα gene expressions folding with TNFα-238 genotypes in beta thalassemia major patients, discovered a considerable increase at GA genotype patients in TNFα gene expression level, followed by AA genotype compared to the GG genotype. Furthermore, the results of the current study showed an association between the presence of the mutant (A) allele whether heterozygous (GA) and homozygous (AA) with the TNF-α gene expression in thalassemia patients with liver and pancreatic disorders. CONCLUSION: Based on the results, it can be concluded that there is a relationship between the presence of the mutant (A) allele, whether heterozygous (GA) or homozygous (AA) of TNF-α 238, and TNF-α gene expression in liver and pancreatic diseases as well as in patients with thalassemia.
