SNPs significantly associated with cognitive performance after Bonferroni correction (full results are in SI Appendix, Table S4)

SNP	Chromosome	Base pair position	Nearest gene	Effective allele	Allele frequency	Years of schooling (Education Sample)		Cognitive performance (Cognitive Performance Sample)
						Standardized coefficient	P value	Standardized coefficient	P value
rs1487441	6	98660615	LOC100129158	A	0.473	0.026	1.78 × 10−9	0.036	1.24 × 10−4
rs7923609	10	64803828	JMJD1C	A	0.521	−0.021	1.06 × 10−6	−0.034	2.58 × 10−4
rs2721173	8	145715237	LRRC14	T	0.473	−0.020	8.61 × 10−6	−0.034	2.88 × 10−4

The chromosome and base pair position are from the National Center for Biotechnology Information genome annotation (build 36), and the nearest gene is from the SCAN database (www.scandb.org/newinterface/about.html). Allele frequency refers to the Cognitive Performance Sample.
