It is worth noting that these SNPs aren't causal, they are just associated. The resolution of GWAS isn't at the level yet where we can pick out individual changes that cause a phenotype. Instead we can detect that a chunk of the genome is associated with a phenotype. These snps are like a street name, they identify the region associated. We need whole-genome sequence on a million-person scale to actually find the causal variant. That will come with time.
