Strong genetic susceptibility to thyroid autoantibody (TAb) diathesis has been shown and one of the major genes involved is probably CTLA-4 gene. Our recent study of patients with Graves' disease has demonstrated that exon 1 CTLA-4 gene polymorphism influences higher TAb production. Here, we evaluated the influence of exon 1 and promoter CTLA-4 polymorphisms on TAb production in 109 newly diagnosed patients with Hashimoto's thyroiditis (HT). Serum TSH, thyroid peroxidase antibodies (TPOAb) and thyroglobulin antibodies (TgAb) were measured. 49 A/G and -318 C/T polymorphisms were detected using polymerase chain reaction amplification of genomic DNA and restriction fragment length polymorphism analysis. Patients with AG and GG genotype had significantly higher TPOAb median values compared to patients with AA genotype (P < 0.003). Similarly, TgAb median value was significantly higher in AG patients and in the entire G-allele carrying group (P < 0.02). Compared to both T-allele carrying genotypes, CC genotype presented with significantly higher TPOAb median value (P < 0.02), whereas TgAb median values did not differ significantly between various genotypes. In conclusion, our results indicate that G allele influences higher TPOAb and TgAb production, whereas C allele affects especially TPOAb production in patients with HT. Therefore, our findings provide further evidence that CTLA-4 is a major TAb susceptibility gene.
