The objective was to investigate putative associations between brain-derived neurotrophic factor gene (BDNF) polymorphisms and brain morphology in patients with schizophrenia and healthy control subjects. Four BDNF polymorphisms were genotyped and analyzed versus 39 brain volume measures in 96 patients with schizophrenia or schizoaffective disorder and 104(More)
BACKGROUND A significant number of patients treated with anthracyclines develop cardiotoxicity (anthracycline-induced cardiotoxicity [ACT]), mainly presenting as arrhythmias (acute ACT) or congestive heart failure (chronic ACT). There are no data on pharmacogenomic predictors of ACT. METHODS AND RESULTS We genotyped participants of the German non-Hodgkin(More)
Polymorphisms in the brain-derived neurotrophic factor (BDNF) gene have been suggested to be associated with schizophrenia. In a replication attempt, Swedish patients with schizophrenia (n=187) and control subjects (n=275) were assessed for four BDNF gene polymorphisms. There were no significantly different allele, genotype or haplotype frequencies between(More)
Several lines of evidence support the theory of schizophrenia (SZ) being a neurodevelopmental disorder. The structural, cytoarchitectural and functional brain abnormalities reported in patients with SZ, might be due to aberrant neuronal migration, since the final position of neurons affects neuronal function, morphology, and formation of synaptic(More)
The power of genome-wide SNP association studies is limited, among others, by the large number of false positive test results. To provide a remedy, we combined SNP association analysis with the pathway-driven gene set enrichment analysis (GSEA), recently developed to facilitate handling of genome-wide gene expression data. The resulting GSEA-SNP method(More)
In quantitative reverse transcription-polymerase chain reaction (qRT-PCR), normalization using reference genes is a common useful approach, but the validation of suitable reference genes remains a crucial problem. Use of unconfirmed reference genes may lead to misinterpretation of the expression of target genes. The aim of this study was to adapt an(More)
OBJECTIVE To investigate associations between brain-derived neurotrophic factor (BDNF) gene polymorphisms and regional frontal cortical thickness and volume in patients with schizophrenia and healthy control participants. METHODS BDNF genotyping was performed using polymerase chain reaction and pyrosequencing techniques in 96 patients with schizophrenia(More)
There is considerable evidence of altered glutamatergic signalling in schizophrenia and a polymorphic variant of the GRIK3 glutamate receptor gene on 1p34-33 has previously been associated to this psychotic disorder. We therefore conducted a systematic association study with 30 HapMap-selected tagging SNPs across GRIK3 in three independent samples of(More)
Altered neurodevelopment and plasticity are implicated in schizophrenia pathology. Based on the important role of neurotrophic factors in brain development and plasticity as well as their extensive expression in hippocampal areas, we hypothesized that a variation in the neurotrophin receptor 3 gene (NTRK-3) is associated to hippocampal function and(More)
BACKGROUND Several aspects of neurocognitive function have high heritability, but the molecular genetic mechanisms underlying neurocognition are not known. We performed a genome-wide association study (GWAS) to identify genes associated with neurocognition. METHODS 700 Subjects (schizophrenia spectrum disorder, n=190, bipolar disorder n=157 and healthy(More)
