Meta-analysis of the association between ZNF512B polymorphism rs2275294 and risk of amyotrophic lateral sclerosis.

Amyotrophic lateral sclerosis (ALS), the most common motor neuron disease, appears to result from the combination of genetic and environmental factors. Whether the rs2275294 polymorphism in the ZNF512B gene influences ALS risk is controversial. We meta-analysed the association between rs2275294 and ALS risk based on evidence published in the PubMed database. Five case-control studies involving 2559 patients with sporadic ALS and 5740 controls were analysed. Based on random-effects meta-analysis, the polymorphism rs2275294 was associated with increased risk of ALS disease in an allele model (C vs. T: OR 1.222, 95%CI 1.057 to 1.414, p = 0.007). The available evidence suggests that the ZNF512B polymorphism rs2275294 is associated with ALS risk. These results should be validated in large, well-designed studies, especially in non-Asian populations.
