Koellinger, which appeared in issue 38, September 23, 2014, of Proc Natl Acad Sci USA (111:13790–13794; first published September 8, 2014; 10.1073/pnas.1404623111). The authors note that on page 13790, in the Abstract, line 15, “KNCMA1, NRXN1, POU2F3, and SCRT” should instead appear as “KCNMA1,NRXN1, POU3F2, and SCRT.”Also, on page 13793, left column, first full paragraph, lines 8–9, “KNCMA1, NRXN1, POU2F3, and SCRT” should instead appear as “KCNMA1, NRXN1, POU3F2, and SCRT.” The authors also note that on page 13792, left column, first full paragraph, line 8, the following sentences should be added after “analyses in ref. 11”: “However, one of the SNPs that is significantly associated with cognitive performance after Bonferroni correction (rs1487441) is in linkage disequilibrium with rs9320913, which is one of the genome-wide significant SNPs reported in ref. 11 in their GWAS of educational attainment. The distance between the two SNPs is 30,839 base pairs and the
