TODO - Purpose: MALT lymphoma is thought to have a genetic component. Genetic studies in the greek population are rare and genetic determinants remain to be established. The current study aimed to seek correlations between genetic polymorphisms and risk of MALT lymphoma in the Greek population. Patients and Methods: 83 MALT lymphoma patients and 60 age-matched healthy outpatients were recruited. SNPs in TNFa, LTA and CTLA-4 genes and IL1RN-VNTR and GSTT1 and GSTTM1 null polymorphisms were genotyped using published PCR/PCR-RFLP methods, while two novel PCR-RFLP methods were developed for IL-22 rs7314777 and TCF19 rs7750641 SNPs. Part of the results was validated by DNA-sequencing. Statistical analysis was performed using SPSS and the SNPstats bioinformatic tool. Results: The mean age of the patients and controls were 55.9 and 56.2 years respectively. The majority of patients (63) suffered gastric marzinal zone lymphoma (GMZL) and 71.1% were stage I at diagnosis. A statistically significant association was noted for the CTLA-4 49A/ G G variant (OR:2.56,p: 0.006) and the TCF19 rs7750641 SNP T variant (OR: 3.86, p:0.023). Conclusions: Our study confirmed a role for CTLA-4 49A/G and TCF19 rs7750641 SNPs in the Greek population. Additional studies could help confirm these associations and possibly link them to prognosis or response to treatment parameters. © 2021 Elsevier Masson SAS
