An Update Evolving View of Copy Number Variations in Autoimmune Diseases.

Autoimmune diseases (AIDs) usually share possible common mechanisms, i.e., a defect in the immune tolerance exists due to diverse causes from central and peripheral tolerance mechanisms.

METTL3 Is Involved in the Development of Graves' Disease by Inducing SOCS mRNA m6A Modification.

Objective: Epigenetic modifications in RNA are known to play critical roles in cell differentiation through regulating expressions of some key genes including members of the suppressor of cytokine signaling (SOCS) family. The present study aimed to unveil the relationship of SOCS mRNA methylation induced by methyltransferase like 3 (METTL3) with Graves' disease (GD).

Methods: Differently expressed genes (DEG) in GD tissues were identified using microarray analysis and further validated using CD4 T cell microarray of GD tissues and isolated peripheral blood mononuclear cells (PBMCs).

Inclusion of ALKBH5 as a candidate gene for the susceptibility of autoimmune thyroid disease.

Purpose: RNA demethylase AlkB homolog 5 (ALKBH5) gene is pivotal in N6-methyladenosine (m6A) modification. Therefore, this study aimed to explore the potential relationship between polymorphisms of ALKBH5 gene and the development of autoimmune thyroid disease (AITD).

Material And Methods: A case-control study of 979 AITD patients, including 620 Graves' disease (GD) and 359 Hashimoto's thyroiditis (HT), and 732 normal controls of the Chinese Han population was performed using high-throughput sequencing (HiSeq) genotyping method for detecting 5 variants in ALKBH5 gene (rs12936694, rs2124370, rs4925144, rs8068517, and rs9913266).

METTL3 gene polymorphisms contribute to susceptibility to autoimmune thyroid disease.

Purpose: Autoimmune thyroid disease (AITD) is a classic autoimmune disorder that mainly includes Graves' disease (GD) and Hashimoto's thyroiditis (HT). In this study, we explored the potential relationship between single-nucleotide polymorphisms (SNPs) of methyltransferase like 3 (METTL3) gene and the development of AITD.

Methods: The distribution of METTL3 genotypes at seven loci (rs1139130, rs1263790, rs1263791, rs17197156, rs2242526, rs3752411, and rs4417466) in 960 AITD (599 GD and 361 HT) patients and 732 unrelated healthy volunteers was examined using high-throughput sequencing technology in a case-controlled manner and their correlations with AITD development were statistically analyzed.
