Lack of association between VEGF polymorphisms and ALS in a Dutch population

Sequence alterations in the promoter region of the vascular endothelial growth factor (VEGF) gene have been implicated in increasing the risk of developing ALS. VEGF promoter haplotypes were determined in 373 patients with sporadic ALS and 615 matched healthy controls in The Netherlands. No significant association between the previously reported at-risk haplotypes and ALS was found. Pooling our results with the previously studied population still showed a significant association with the AAG haplotype.
