Schizophrenia as a pseudogenetic disease: A call for more gene-environmental studies

  title={Schizophrenia as a pseudogenetic disease: A call for more gene-environmental studies},
  author={E Fuller Torrey and Robert H. Yolken},
  journal={Psychiatry Research},
In recent years schizophrenia has been assumed to be largely a genetic disease with heritability estimates, derived primarily from family and twin studies, of 80%-85%. However, the results of genetic research on schizophrenia have not yielded results consistent with that estimate of heritability. In particular, extensive genetic studies have not led to new methods for diagnosis and treatment. An examination of the twin studies on which heritability is based shows why such studies exaggerate the… Expand
New Insights Regarding Diagnosis and Medication for Schizophrenia Based on Neuronal Synapse–Microglia Interaction
The hypothesis that excessive synaptic pruning plays a role in the development of schizophrenia is introduced and a strategy for diagnosis and medication based on modulation of the interaction between microglia and synapses is suggested. Expand
Association Between Childhood Green Space, Genetic Liability, and the Incidence of Schizophrenia.
The results suggest that risk of schizophrenia is associated additively with green space exposure and genetic liability, and provide no support for an environment-gene interaction between NDVI and schizophrenia. Expand
Tracking a dysregulated gut-brain axis with biomarkers of the microbiome
Direct measures of microbial taxonomy present in gut communities and indirect measures of host responses to gut dysbioses are reviewed, indicating that it will be equally important to characterize host phenotypes that relate to specific microbial compositions. Expand
Toxoplasma gondii and Psychopathology: Latent Infection Is Associated with Interpersonal Sensitivity, Psychoticism, and Higher Testosterone Levels in Men, but Not in Women
Objective The ability of parasites to hijack the nervous system, manipulating the host’s physiology and behavior in ways that enhance the parasite’s fitness while damaging host fitness, is a topic ofExpand
Infections, inflammation, and risk of neuropsychiatric disorders: the neglected role of “co-infection”
Understanding about the role of co-or-multiple infections can offer new insights about the etiology, treatment and prevention of NPDs and therapy based on anti-infective and anti-inflammatory agents could be a promising therapeutic option as an adjuvant for treatment of N PDs. Expand
Infection with Toxoplasma gondii increases the risk of psychiatric disorders in Taiwan: a nationwide population-based cohort study
It is revealed that Toxoplasma gondii infection in Taiwan significantly increases the risk for developing bipolar disorder, depression and anxiety, but not for schizophrenia and other psychiatric disorders. Expand
Exposure to household pet cats and dogs in childhood and risk of subsequent diagnosis of schizophrenia or bipolar disorder
Exposure to household pets during infancy and childhood may be associated with altered rates of development of psychiatric disorders in later life, and there were trends towards an increased risk of both disorders at defined periods of exposure. Expand
Social preference is maintained in mice with impaired startle reflex and glutamate/D-serine imbalance induced by chronic cerebral toxoplasmosis
It is concluded that behavioral and cognitive aspects are maintained even though severe neural damage is observed by chronic infection of C57Bl/6 mice with the ME-49 strain, and the startle amplitude is reduced in the infected animals. Expand
Dysfunctional family functioning in high socioeconomic status families as a risk factor for the development of psychiatric disorders in adoptees: the Finnish Adoptive Family Study of Schizophrenia
It was showed that in HSES families, dysfunctional family processes and HR for schizophrenia increased the likelihoods for the development of psychiatric disorders in adoptees. Expand
Natural surroundings in childhood are associated with lower schizophrenia rates
It is suggested that ensuring access to natural environments during childhood may be important for schizophrenia prevention, whilst being the first study to show that natural environments may influence schizophrenia rates through multiple pathways. Expand


The role of genetics in the etiology of schizophrenia.
The aggregate data provide support for polygenic inheritance and for genetic overlap of schizophrenia with autism and with bipolar disorder. Expand
Twin studies of schizophrenia: from bow-and-arrow concordances to star wars Mx and functional genomics.
The five newest studies since 1995 from Europe and Japan have confirmed earlier findings on the genetic basis of clinical heterogeneity within schizophrenia and provided further insights into non-inherited factors that contribute to the multifactorial etiology of this disorder. Expand
After GWAS: searching for genetic risk for schizophrenia and bipolar disorder.
Ten years ago it was widely expected that the genetic basis of common disease would be resolved by genome-wide association studies (GWAS), large-scale studies in which the entire genome is covered byExpand
Are we overestimating the genetic contribution to schizophrenia?

Although genetics remains as the single most clearly defined etiological factor in schizophrenia, the question remains whether the authors are overestimating the magnitude of the genetic contribution. Expand
The complement system: a gateway to gene-environment interactions in schizophrenia pathogenesis
The complement system could be used as one of the ‘staging posts’ for a variety of focused studies of schizophrenia pathogenesis, including GEI studies of the C4A/C4B repeat polymorphisms in relation to inflammation-related or infectious processes, animal model studies and tests of hypotheses linked to autoimmune diseases that can co-segregate with schizophrenia.

Genome-wide Association Studies: Findings at the Major Histocompatibility Complex Locus in Psychosis
The structure and function of the MHC is described, some of the challenges for genetic analysis of the region are discussed, and an update on findings from GWAS studies are provided before describing potential approaches to interpreting the role of the locus in schizophrenia etiology. Expand

Genetic discoveries about human brain development and neuropsychiatric syndromes have changed the landscape of psychiatric research. The genotyping of hundreds of thousands of individuals hasExpand
Contrasting genetic architectures of schizophrenia and other complex diseases using fast variance components analysis
A fast algorithm for multicomponent, multi-trait variance-components analysis that overcomes prior computational barriers that made such analyses intractable at this scale is developed. Expand
Evaluating the dopamine hypothesis of schizophrenia in a large-scale genome-wide association study
Within the limits of available power, common sequence variation within core genes of the dopaminergic system is not related to risk of schizophrenia, and this does not preclude a role of dopamine, or dopamine-related genes, in the clinical presentation of schizophrenia or in treatment response. Expand
Schizophrenia, psychiatric genetics, and Darwinian psychiatry: an evolutionary framework.
This article conceptualizes schizophrenia in a compensatory advantage framework whereby incomplete penetrance of the full disorder, or alternatively, the inheritance of risk alleles insufficient in number to manifest as the classic clinical syndrome, may manifest as a behavioral phenotype with adaptive advantages (eg, creative behavior or novel illuminating ideas).
