In Egypt, hepatocellular carcinoma (HCC) ranks as the second largest cause of cancer mortality. PRDM1 is a tumor suppressor gene essential for the differentiation and regulation activity of plasma cells and T cells. It plays a vital role in T cell exhaustion of chronic viral infection and HCC. We aimed to study the role of PRDM1 gene polymorphism in HCV and HCC‐related to hepatitis C virus (HCV) progress in Egyptians. The case‐control study included 300 Egyptian patients divided into 100 HCC,100 cirrhosis, and 100 control. Laboratory investigations were done for some clinicopathological biomarkers, including liver function tests, complete blood picture, serum alpha‐fetoprotein, and hepatitis markers (HBsAg, anti‐HCV‐Ab). TaqMan allelic discrimination assay technique was used to genotype PRDM1 gene polymorphism. Multivariant analysis (logistic regression) assessed the association between the polymorphisms with HCC progression and designed the suggested model for HCC prediction. The frequencies of the G allele and GG phenotype in the control group were significantly more than that of the HCC and cirrhosis group. However, GA genotypes and A allele frequencies significantly increased in the HCC patients than in cirrhosis and controls. In addition, by comparing the HCC group and the non‐HCC group (controls and cirrhotic patients), the subjects carrying AA or GA have 2 times more risk to develop HCC than those carrying GG genotypes (odd ratio = 2.045% and 95% confidence interval are (1.123−3.722) p = 0.019). Multivariate analysis results suggested a model of Aspartate transaminase (AST), Albumin, and PRDM1 polymorphism to predict the risk of HCC in Egyptians. In addition, PRDM1 polymorphism has an association with HCC prognosis (tumor size). For PRDM1 polymorphism, the A allele and AA might be considered as HCC‐related to the HCV risk factor. In addition, AST, Albumin, and PRDM1 polymorphism predict the risk of HCC in Egyptians Therefore, the polymorphism might help in identifying the susceptible Egyptians to HCC. In addition, polymorphism might have a role in HCC prognosis. [ABSTRACT FROM AUTHOR]
