Over the last decade, genome-wide association studies (GWAS) of psychiatric disorders have identified numerous significant loci. Whereas these studies initially depended on cohorts ascertained for specific disorders, there has been a gradual shift in the ascertainment strategy towards population-based cohorts (PBCs) for which both genotype and heterogeneous phenotypic information are available. One of the advantages of PBCs is that, in addition to clinical diagnoses and various proxies for diagnoses (“minimal phenotyping”), many of them also provide non-clinical phenotypes, including putative endophenotypes, that can be used to study domains of normal function in addition to, or instead of, clinical diagnoses. By studying endophenotypes it is possible to both dissect psychiatric disorders (“splitting”) and to combine multiple phenotypes (“clumping”), which can either reinforce or challenge traditional diagnostic categories. Such endophenotypes may also permit a deeper exploration of the neurobiology of psychiatric disorders. A coordinated effort to fully exploit the potential of endophenotypes is overdue.
