rs268972 is located at the cadherin 12 type 2 (CDH12) locus which belongs to the cadherin superfamily that mediate calcium-dependent cell–cell adhesion and cadherins adhesion are regulated by the canonical wnt signaling pathway (37). CDH12 is expressed in the brain and may play a role in neuronal development. rs6088887 is located in the intron of fer-1-like 4 (FER1L4) which has an unknown function.
