Possible interactions between ASD causal genes and WNT signaling. Most molecules (red) encoded by the ASD-associated genes are either core components of WNT signaling pathways, such as WNTs, APC, β-catenin, TCF7L2, and PRICKLE2, or their modulators, such as DIXDC1, PGE2, UBE3A, and CHD8. ANK3 interacts with β-catenin at the plasma membrane. Note: plus sign indicates upregulation; minus sign indicates downregulation
