A two-stage case-control study in a Chinese Han population examined 820 Behçet's disease (BD) and 900 VKH syndrome patients versus 1,800 controls. The miR-182/rs76481776 SNP showed significantly decreased CC genotype and C allele frequencies in BD (OR=0.55-0.58, P=3.36×10⁻⁴ to 3.25×10⁻⁷) and VKH patients (OR=0.53-0.57, P=1.11×10⁻⁴ to 7.89×10⁻⁸). Other SNPs in miR-27a, FoxO1, and IL2RA showed no significant associations. Functional analysis revealed increased miR-182 expression in TT/CT genotypes compared to CC in anti-CD3/CD28 antibody-stimulated CD4+ T cells (P=2.1×10⁻²).

This review examines slowly progressive type 1 diabetes mellitus (SPIDDM), also known as latent autoimmune diabetes in adults (LADA), discussing its pathogenesis, diagnostic markers, and genetic associations. Key findings include T-cell-mediated insulitis and pseudoatrophic islets characteristic of type 1 diabetes, absence of amyloid deposition seen in type 2 diabetes, and identification of multiple genetic susceptibility loci including HLA haplotypes, PTPN22 rs2476601, INS rs689, CTLA4, TCF7L2 rs7903146, ZMIZ1 rs12571751, SH2B3 rs7310615, and PFKFB3 rs1983890. GAD autoantibodies and HLA genotypes are important risk factors for beta-cell failure progression.
