Background
Previous studies have investigated the association between rs2304016 and rs17183814 polymorphisms in sodium voltage-gated channel alpha subunit 2 (SCN2A) and epilepsy risk and responsiveness to antiepileptic drugs (AEDs) but with conflicting results. Our aim was to reevaluate the relationship by performing a systematic review and meta-analysis.
Methods
By searching PubMed, Medline, and CNKI, 14 studies were selected. Pooled odds ratios (ORs) and 95% confidence intervals (CIs) were computed to measure the association between rs17183814 and rs2304016 polymorphisms and the risk of epilepsy and AEDs response using the fixed-effects model or the random-effects model.
Results
No significant association between the rs17183814 in SCN2A and the risk of epilepsy was observed (heterozygous comparison: OR = 0.78, 95% CI: 0.61–1.00; homozygous comparison: OR = 1.34, 95% CI: 0.63–2.86; dominant model: OR = 0.82, 95% CI: 0.64–1.04; recessive model: OR = 1.44, 95% CI: 0.68–3.05; allele comparison: OR = 0.88, 95%CI: 0.71–1.10). Moreover, neither the rs17183814 nor the rs2304016 was associated with AEDs response.
Conclusion
This meta-analysis suggests that the rs17183814 and rs2304016 polymorphisms in SCN2A are not associated with the risk of epilepsy and response to AEDs.
