Association Between Genetic Risk for #Psychiatric Disorders and the Probability of Living in #Urban Settings

Urban residence has been highlighted as an environmental risk factor for schizophrenia and, to a lesser extent, several other psychiatric disorders. However, few studies have explored genetic effects on the choice of residence. Objective To investigate whether individuals with genetic predisposition to a range of psychiatric disorders have an increased likelihood to live in urban …

Association of #Mitochondrial Biogenesis With Variable Penetrance of #Schizophrenia

Discovery of mechanisms that underlie variable penetrance for neuropsychiatric illness in the context of genetic variants that carry elevated risk can advance novel treatment approaches for these disorders. Objective To test the hypothesis that mitochondrial compensation is associated with the variable penetrance of schizophrenia in the 22q11.2 deletion syndrome (22q11DS). Design, Setting, and Participants This …

#Disruption of the blood−brain barrier in 22q11.2 deletion syndrome

Neuroimmune dysregulation is implicated in neuropsychiatric disorders including schizophrenia. As the blood−brain barrier is the immunological interface between the brain and the periphery, we investigated whether this vascular phenotype is intrinsically compromised in the most common genetic risk factor for schizophrenia, the 22q11.2 deletion syndrome (22qDS). Blood−brain barrier like endothelium differentiated from human 22qDS+schizophrenia-induced pluripotent …

Increased Risk of #Parkinson’s Disease in Patients With #Schizophrenia Spectrum Disorders

PD comorbid with schizophrenia has been considered rare because these diseases associate with opposite alterations in the brain dopamine system. The objective of this study was to investigate the risk of PD after a diagnosis of a schizophrenia spectrum disorder. Methods Regionally, this was a retrospective record‐based case–control study. The cohort included 3045 PD patients …

#ABCA13 dysfunction associated with #psychiatric disorders causes impaired cholesterol trafficking

ATP-binding cassette subfamily A member 13 (ABCA13) is predicted to be the largest ABC protein, consisting of 5,058 amino acids and a long N-terminal region. Mutations in the ABCA13 gene were reported to increase the susceptibility to schizophrenia, bipolar disorder and major depression. However, little is known about the molecular functions of ABCA13 or how …
