    Abstract:
    Vascular endothelial growth factor (VEGF) is a cytokine essential for angiogenesis. A recent study found that haplotypes, determined by three SNPs (-2,578C/A, - 1,154 G/A, and - 634G/C) in the VEGF upstream promoter/leader sequence, were associated with risk of amyotrophic lateral sclerosis(ALS). We used samples and data from a case-control study to examine the relation of ALS to VEGF haplotype. Genotypes at each of the three polymorphic sites were determined using allele-specific primer extension reactions followed by MALDI-TOF. We found a 3-fold increased risk among individuals homozygous for the AAG or AGG haplotypes (95%CI = 0.7 - 13.4), consistent with the findings of the previous study. Given the wide confidence interval, our findings should be interpreted cautiously.
