CRKL and schizophrenia: Using CRKL and an additional gene, GRAP2, one of the first-degree neighbors not in the DisGeNet list but suspected to be linked with schizophrenia [36], we were able to create a fully connected subnetwork with those 14 genes and visualized it as Fig. 2B. Supplementary Material S4 provides the full list of pathways that include any of the 14 genes.
