The methylenetetrahydrofolate reductase (MTHFR) C677T gene variant is not linked to overall ischemic stroke risk. However, it may increase the risk of the atherothrombotic subtype in Morocco.
Area of Science:
- Genetics and Neurology
- Molecular Biology
- Epidemiology
Background:
- The association between methylenetetrahydrofolate reductase (MTHFR) C677T gene variants and ischemic stroke risk remains debated.
- Understanding genetic predispositions is crucial for stroke prevention strategies.
Purpose of the Study:
- To investigate the association between MTHFR C677T gene variants and ischemic stroke risk in a Moroccan population.
- To explore potential links between MTHFR C677T variants and specific stroke subtypes.
Main Methods:
- A case-control study was conducted in Casablanca, Morocco, involving 91 ischemic stroke cases and 182 matched controls.
- Polymerase chain reaction (PCR) followed by HinfI enzymatic digestion was used to determine allele and genotype frequencies.
Main Results:
- No statistically significant association was found between MTHFR C677T T allele carriers and overall ischemic stroke risk (OR, 1.1; 95% CI, 0.59-2.04; P = 0.303).
- A significant association was observed between T allele carriers and the atherothrombotic stroke subtype (n=42) (OR, 2.1; 95% CI, 1.17-3.8; P = 0.012).
- The TT genotype showed a significantly adjusted odds ratio of 6.5 (95% CI, 1.86-23.1; P = 0.003) for atherothrombotic stroke compared to the CC genotype.
Conclusions:
- The MTHFR C677T gene variant may be a determinant factor for atherothrombotic events in ischemic stroke patients within the Moroccan population.
- Further research is warranted to elucidate the specific mechanisms linking MTHFR C677T variants to atherothrombotic stroke.
