From SNPedia

A large GWAS has found 74 regions related to educational attainment which collectively explain 0.43% of the variation across individuals. The study was composed of over 400,000 subjects. As noted in the article educational attainment is strongly related to social and environmental factors, though genetics do play some role estimated at 20%.
