The polymorphisms Glu298Asp and C677T, affecting the eNOS and 5,10-MTHFR enzymes, respectively, and smoking, hypertension, and family history of stroke were associated with ischaemic stroke in young Mexican patients; this was not the case for the Thr325Ile, Ala147Thr, 4G/5G, and PLA1/A2 polymorphisms of the genes coding for fibrinolytic proteins and platelet receptors.

After excluding articles that deviated from the Hardy-Weinberg equilibrium in controls and the key contributors to between-study heterogeneity, significant associations between the MTHFR C677T genetic polymorphism and the risk of hemorrhagic stroke were observed in dominant (Odds ratio [OR] 1.611, 95% confidence interval [CI] 1.336-1.942), codominant (OR 1.500, 95% CI 1.330-1.692), and recessive (OR 1.695, 95% CI 1.409-2.038) models.
