No associations were reported in the GWAS Catalog for three of the novel loci, with lead SNPs rs2055873 mapped to LMNB1 and MARCH3, rs7776042 mapped to RNF144B and ID4, and rs7184217 in gene CACNG3. Associations of SNPs in LD with significant SNPs in the regions showed associations with several cognitive, psychiatric and neurodevelopmental phenotypes, particularly ADHD [40, 41]. This evidence concerns the gene CACNG3 and attention deficit-hyperactivity disorder.
