MTHFR C677T and A1298C polymorphisms in dementia susceptibility: evidence from a meta-analytic investigation with disease-specific and ethnicity-stratified analyses
Background Alzheimer’s disease (AD) and vascular dementia (VaD) have become significant global health challenges. Recent research evidence indicates a close comorbidity between AD and cerebral small vessel disease. The C677T (rs1801133, also known as c.665C > T) and A1298C (rs1801131) polymorphisms in the methylenetetr...
