Abstract:
To identify association between the presence of previously reported four single nucleotide polymorphisms(SNPs) at exon 10, 12 and 33 of thyroglobulin(Tg) gene with autoimmune thyroid disease(AITD) patients whose TgAb is positive. In this case-control association study, the Tg gene polymorphisms at exon 10, 12, and 33 were determined by polymerase chain reaction-restriction fragment length polymorphism(PCR-RFLP)method in 222 patients with AITD. According to the titers of the Tg autoantibodies(TgAb) in serum, they were divided into two subgroups: TgAb positive group and TgAb negtive group. And a haplotype case-control analysis was also done in two groups.The difference of their frequencies was analyzed by Chi-square test. No differences in alleles and genotypes frequencies were observed in all patients whose TgAb iseither positive or negative(P＞0.05). But there was a significant association of G-C-A-C haplotype with the patients whose TgAb was positive(P=0.028,OR=3.34). There is association of thyroglobulin gene polymorphisms with TgAb in patients with AITD.
