However, the role of NRG1 in the etiology of schizophrenia has remained unclear. Since Nrg1 serves vital functions in early brain development of mice, we hypothesized that human NRG1 alleles codetermine developmentally influenced readouts of the disease: age of onset and positive symptom severity. We analyzed 1,071 comprehensively phenotyped schizophrenic/schizoaffective patients, diagnosed according to DSM-IV-TR, from the GRAS (Göttingen Research Association for Schizophrenia) Data Collection for genetic variability in the Icelandic region of risk in the NRG1 gene. For the case-control analysis part of the study, we included 1,056 healthy individuals with comparable ethnicity. The phenotype-based genetic association study (PGAS) was performed on the GRAS sample. Instead of a risk constellation, we detected that several haplotypic variants of NRG1 were, unexpectedly, less frequent in the schizophrenic than in the control sample (mean OR=0.78, range between 0.68 and 0.85). In the PGAS we found that these \"protective\" NRG1 variants are specifically underrepresented in subgroups of schizophrenic subjects with early age of onset and high positive symptom load. The GRAS Data Collection as a prerequisite for PGAS has enabled us to associate protective NRG1 genotypes with later onset and milder course of schizophrenia."],["dc.identifier.doi","10.1002/ajmg.b.31168"],["dc.identifier.gro","3150547"],["dc.identifier.pmid","21234898"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/7321"],["dc.language.iso","en"],["dc.notes.status","final"],["dc.title","A phenotype-based genetic association study reveals the contribution of neuregulin1 gene variants to age of onset and positive symptom severity in schizophrenia"],["dc.type","journal_article"],["dc.type.internalPublication","unknown"],["dc.type.peerReviewed","yes"],["dspace.entity.type","Publication"]]

In turn, AUD worsens the outcome of psychiatric patients with respect to global disease severity, social situation, and socioeconomic burden. Prediction of persons at risk for AUD is crucial for future preventive and therapeutic strategies.Objective To investigate whether genetic variants of the corticotropin-releasing factor system or their interaction influence the risk of developing AUD in chronic disease populations.Design Genotype analysis comprising selected single-nucleotide polymorphisms within the CRHR1 and CRHBP genes in patients with schizophrenia and in a nonschizophrenic psychiatric disease control sample should allow the extraction of predictors of comorbid AUD.

Therefore, treatment processes of 64 chronic alcohol dependent patients have been investigated at three time-points, t1 (week 3), t2 (month 6), and t3 (month 12) during the first year of a comprehensive outpatient treatment program, guaranteeing strictly controlled alcohol abstinence. Main focus of the study was the prediction of cumulative abstinence probability over a follow-up period of up to 4 years based on these treatment processes. One hundred and seventy-five video recordings of therapy sessions were analyzed with the behavior observational system VAMP (Video-Assisted Monitoring of Psychotherapeutic Processes in Chronic Psychiatric Disease). Patients’ self-rating of treatment processes was measured with questionnaires for self-efficacy, abstinence confidence, self-consciousness and stress coping. Prediction of cumulative abstinence probability was determined with Cox regression analysis. By integrating the observer rated process variables with the highest predictive validity, the composite score TOPPS (Therapy Orientation by Process Prediction Score) was constructed. It includes the process variables experience of resources, abstinence self-efficacy, implicit craving, relapse alertness, relapse risk, disease concept, dysfunctional therapeutic engagement, and dysfunctional problem solving of current problems. Whereas patients’ self-rating of treatment processes was insufficiently predictive, the TOPPS strongly predicted four-year abstinence probability at any of the 3 time-points (p < 0.001).
