We determined the frequency of the C9ORF72 hexanucleotide repeat expansions in a population of 298 patients with schizophrenia or schizoaffective disorder.
To our knowledge, this is the first instance of disease-specific mutations in schizoaffective disorder, which warrants systematic screening of the regulatory and coding regions of the calreticulin gene in this disorder.
These findings suggest that the alterations in SST-containing interneurons in schizophrenia and schizoaffective disorder are selective for the subset that do not express NPY mRNA, and that lower NPY mRNA expression in the superficial white matter may distinguish subjects with schizoaffective disorder from those with schizophrenia.
Our results point to a previously unknown causal role for dysregulation of calreticulin homeostasis in schizoaffective disorder by both genetic and functional analyses, and shed new light on the possible mechanisms of action of valproate and lithium in the treatment of the disease.
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.
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.
Weak association of the platelet-derived growth factor beta (PDGFB) and PDGF receptor beta (PDGFRB) genes with schizophrenia and schizoaffective disorder.
These findings suggest that the alterations in SST-containing interneurons in schizophrenia and schizoaffective disorder are selective for the subset that do not express NPY mRNA, and that lower NPY mRNA expression in the superficial white matter may distinguish subjects with schizoaffective disorder from those with schizophrenia.
We conclude TCF7L2, a risk factor for T2D in the general population, is also a risk factor for T2D in African-American patients with SCZ or schizoaffective disorder.
The utility of SELENBP1 gene expression as a biomarker for major psychotic disorders: replication in schizophrenia and extension to bipolar disorder with psychosis.
