This report describes general characteristics of schizophrenia (SCZD), specifically subtypes that confer susceptibility to schizophrenia. Schizophrenia is highly heritable but the genetics are complex; multiple loci that appear to confer susceptibility to the disease have been identified. A phenotypic series for subtypes of schizophrenia has not been defined by OMIM as of this update; see MIM:181500.

Schizophrenia is a psychosis, a disorder of thought and sense of self. Although it affects emotions, it is distinguished from mood disorders in which such disturbances are primary. Similarly, there may be mild impairment of cognitive function, and it is distinguished from the dementias in which disturbed cognitive function is considered primary. Schizophrenia often develops in young adults who were previously normal, and is characterized by a constellation of symptoms including hallucinations and delusions (psychotic symptoms) and symptoms such as severely inappropriate emotional responses, disordered thinking and concentration, erratic behavior, as well as social and occupational deterioration (Andreasen, 1995; pubmed:7637483).

Schizophrenia is a common disorder with a lifetime prevalence of approximately 1%. It is highly heritable, but the genetics are complex. [from MIM:181500; 2017.04.18]
There is no characteristic pathology associated with schizophrenia (such as neurofibrillary tangles in Alzheimer disease). [from MIM:181500; 2017.04.18]
