A 2026 Han Chinese case-control preprint linked the MTHFR C677T variant to schizophrenia with type 2 diabetes: the 677T allele appeared in 81.67% of alleles in the comorbid group vs. 60.00% in controls (p = 0.009), while MTHFR promoter methylation was nearly saturated in both groups (95.00% vs. 90.00%; p = 1.000).
