- Association was assessed with rs11225308, rs363449, rs17278234, and the 10- and 43-SNP sets previously associated with mathematics at age 10. Associations are presented as correlations between the quantitative traits and additive genotypic values (as 0, 1, and 2 'increasing' alleles) for SNPs and additive SNP scores for SNP sets. G at 10 = general cognitive ability at age 10; Teacher reading at 10 = NC-based teacher-ratings of reading ability at age 10; Web reading at 10 = performance on web-administered tests of reading at age 10; Cor = Pearson product moment correlations (p-values in italics); N = size of sample analysed; r
p
= phenotypic correlation with mathematic composite score at age 10. One-tailed p-values were generated for all SNP-associations. * = nominally significant associations (p < 0.05). ** = associations withstanding Bonferroni testing for the five (three individual SNP and two SNP-set) association tests conducted simultaneously for each measure (p < 0.01).
