Regarding intelligence and schizophrenia, MAAT identified 21 genes with high association levels in these two traits, where the significant function of ACTR1A, C22orf46, CKB, CYP2D6, LRRC37A, NCK1, and ZMAT2 have been well validated in large-scale GWAS studies. Here, NCK1 is linked to schizophrenia.
