One of the numerous such examples is the significant causal association between educational attainment and ERCC8 (PTWMR = 1.05 × 10−13), a gene previously linked with the monogenic Cockayne Syndrome A (OMIM#216400)50 in the ELOVL7 region (top SNP: rs61160187, P = 5.93 × 10−13). This evidence concerns the gene ERCC8 and Cockayne syndrome type 1.
