Over 300 psychiatric disorders have been described, and nine are covered in this review. The conditions selected are: all psychiatric disorders; have been subjected to intensive genetic study; and have published genome-wide results (usually GWAS and SV but also genome-wide linkage and resequencing). The disorders and their abbreviations are defined in Tables 1 and S1, and the heritabilites and lifetime prevalences are depicted in Figure 1a. Mental retardation could have been included, but its voluminous literature has been reviewed at length. 7–9 Studies of other psychiatric disorders are in progress, but the published data are few (e.g., obsessive-compulsive disorder, Tourette’s syndrome, and panic disorder).
