so for autism and epilepsy. While schizophrenia stood out the most from ID, under broad criteria schizophrenia’s relationship with ID would be most consistent with a subsumed model as well. However, the schizophrenia specific CNVs should be interpreted with caution as some have been found thus far only in a single study. The interpretation of these findings suggests that ID may represent a disorder with the broadest possibilities of genetic mechanisms and susceptibility pathways, and the other disorders appear to have more restricted susceptibilities.
