Association results for general cognitive function. SNP-based (a) and gene-based (b) association results in 300,486 individuals. The red line indicates the threshold for genome-wide significance: P < 5 × 10−8 for (a), P < 2.75 × 10−6 for (b); the blue line in (a) indicates the threshold for suggestive significance: P < 1 × 10−5
