Association Between NEAT1 rs512715 Gene polymorphism and Hashimoto Thyroiditis and Graves’ Disease: A Case-Control Study

Abstract

Background: Some evidence demonstrated the relationship between long non-coding RNA and autoimmune disease development. The current study assessed the possible association between the nuclear enriched abundant transcript 1 (NEAT1) gene rs512715 polymorphism and Hashimoto and Graves’ diseases. Methods: Two hundred forty-eight participants with autoimmune thyroid disease (133 Hashimoto thyroiditis (HT) patients and 115 Graves’ disease (GD) patients) and 135 age- and sex-matched controls were enrolled in the study. The polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) method was used for genotyping NEAT1 rs512715 polymorphism. Results: Significant differences were observed in the frequency of the CC genotype of rs512715 in the HT group compared to the controls; the CC genotype may act as a risk factor for HT development. Also, the dominant and recessive genetic models showed the same results. Regarding the frequency of alleles, the C allele frequency was higher in the HT group than in the controls. In the GD group, there was no significant difference in the distribution of genotypes and the genetic models. Also, no significant difference was observed in the frequencies of alleles in Graves’ patients. Conclusions: Our findings indicated that NEAT1 rs512715polymorphism might play an influential role in Hashimoto’s disease development as the risk factor.
