Abstract

Background: The MICA gene encodes for MICA molecule, acts as ligands for the immunogenic NKG2D receptor. The expression of MICA can be caused by inducing “stress” in cells that are malignantly transformed or infected with viruses. Several studies have investigated the relationship between SNP rs2596542 on MICA gene and the risk of nasopharyngeal cancer, hepatocellular carcinoma caused by hepatitis C virus and hepatitis B virus. However, no studies have been performed on patients with lymphoma. Objectives: Identification of SNP rs2596542 on MICA gene and the risk of lymphoma. Materials and methods: This study determined the allele frequency of SNP rs2596542C/T on MICA gene in lymphoma patients was 29.5% T, 70.5% C, respectively; genotype distribution is 53% CC, 35% CT and 12% TT, respectively. However, no statistical significance was observed between genotype and allele frequency of SNP rs2596542 in the patient and control group.
