Age (years) | Sex (male/female) | Handedness (right/left) | IQb (mean ± SD) | |
---|---|---|---|---|
Major allele carriers (n = 177) | 37.9 ± 18.5 (8.8–86.0) | 98/79 | 158/19 | 112 ± 11 |
Minor allele homozgotes (n = 30) | 45.1 ± 22.0 (9.9–81.0) | 11/19 | 26/4 | 113 ± 12 |
↵aAge and IQ are mean ± SD. Data were collected at two study sites. Haplotype status was determined with the rs174583 SNP within the FADS2 gene, which tags a haplotype spanning the FADS1 gene and first part of the FADS2 gene (Ameur et al., 2012).
↵bEstimated using the Wide Range Achievement Test 3 (Reading subtest; Wilkinson, 1993); data missing for 13 major allele carriers and 2 minor allele homozygotes.
