Regarding the PSMD3 rs3087852 SNP, A allele carriers (G/A + A/A genotypes) showed lower UAE than those with the G/G genotype [9.5 mg/g (4.8–40.5) vs. 19.0 mg/g (5.0–196.4), p = 0.016, dominant model], and this association persisted after adjustment for HbA1c, T1DM duration, hypertension, and presence of DR [Exp(B) = 0.640; 95% CI: 0.441–0.930; p = 0.019 from Gamma GLM]. Here, PSMD3 is linked to type 1 diabetes mellitus.
