Disrupted in schizophrenia 1 (DISC1) has been associated with risk of schizophrenia, schizoaffective disorder, bipolar disorder, major depression, autism and Asperger syndrome, but apart from in the original translocation family, true causal variants have yet to be confirmed.
BDNF genotyping was performed using polymerase chain reaction and pyrosequencing techniques in 96 patients with schizophrenia or schizoaffective disorder and 104 healthy control participants.
A recent association study of alpha(1A)-adrenoceptor gene (ADRA1A) involving an isolated Spanish population, focusing on the promoter region of the ADRA1A, genotyped eight single SNPs at the promoter region of ADRA1A and found that two SNPs, -563G/A and -9625G/A, were associated with schizophrenia and schizoaffective disorders.
Allelic variation at the DRD4 locus does not predict clinical response to clozapine relative to either fluphenazine hydrochloride or placebo in subjects with treatment-refractory schizophrenia or schizoaffective disorder.
Among 67 patients who received ECT and diagnosed with schizophrenia/schizoaffective disorder based on the criteria of the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, Text Revision, we included 56 patients who received 1-millisecond BP-BL ECT after anesthesia with sodium thiopental between March 2012 and June 2018.
An available, prospectively collected data base was interrogated to determine how three Sult4A1 SNPs: rs138060, rs138097, and rs138110, previously shown to be associated with schizophrenia might be associated with psychopathology, cognition, and quality of life in a sample of 86 Caucasian patients with schizophrenia or schizoaffective disorder.

Associations of schizophrenia subtypes, psychotic symptoms (defined by SAPS/SANS and OPCRIT), affective episodes and demographic variables were studied in 109 sibling pairs with DSM-IV schizophrenia or schizoaffective disorder.
Based on the genetic and functional evidence that DISC1 may be associated with schizophrenia, we sequenced portions of DISC1 in 28 unrelated probands with schizophrenia and six unrelated probands with schizoaffective disorder, ascertained as part of a large sibpair study.
Eighty-eight acutely ill patients with schizophrenia or schizoaffective disorder were genotyped for rs6280" genes_norm="1814">ser-9-gly (rs6280) and 23 other polymorphisms within the DRD-3 gene.
Fifty patients with schizophrenia or schizoaffective disorder by DSM-III-R criteria were genotyped at 5-HTTLPR and underwent double-blind Brief Psychiatric Rating Scale (BPRS) ratings while neuroleptic-free for approximately 4 weeks.
Forty-nine patients, with schizophrenia or schizoaffective disorder and treated with clozapine (n = 22) or olanzapine (n = 27), were evaluated for fasting levels of C-peptide, insulin and blood glucose, homeostasis model assessment index for insulin resistance (HOMA-IR) and body mass index (BMI), and genotyped for the -1438A/G, -783A/G, 102T/C, and His452Tyr polymorphisms of the HTR2A gene.
Fourth, we show that the blood levels of SAT1 (spermidine/spermine N1-acetyltransferase 1), the top biomarker identified by us, at the time of testing for this study, differentiated future as well as past hospitalizations with suicidality, in a live cohort of bipolar disorder subjects, and exhibited a similar but weaker pattern in a live cohort of psychosis (schizophrenia/schizoaffective disorder) subjects.
