Relationship between a high-risk haplotype in the DTNBP1 (dysbindin) gene and clinical features of schizophrenia.
OBJECTIVE The purpose of this study was to determine whether a haplotype in the dystrobrevin binding protein 1 (DTNBP1) gene previously associated with schizophrenia not only increases the susceptibility to psychotic illness but also to a more or less clinically specific form of psychotic illness. METHOD In the Irish Study of High-Density Schizophrenia Families, subjects with psychotic illnes...
متن کاملDTNBP1, a schizophrenia susceptibility gene, affects kinetics of transmitter release
Schizophrenia is one of the most debilitating neuropsychiatric disorders, affecting 0.5-1.0% of the population worldwide. Its pathology, attributed to defects in synaptic transmission, remains elusive. The dystrobrevin-binding protein 1 (DTNBP1) gene, which encodes a coiled-coil protein, dysbindin, is a major susceptibility gene for schizophrenia. Our previous results have demonstrated that the...
متن کاملThe schizophrenia susceptibility gene dysbindin regulates dendritic spine dynamics.
Dysbindin is a schizophrenia susceptibility gene required for the development of dendritic spines. The expression of dysbindin proteins is decreased in the brains of schizophrenia patients, and neurons in mice carrying a deletion in the dysbindin gene have fewer dendritic spines. Hence, dysbindin might contribute to the spine pathology of schizophrenia, which manifests as a decrease in the numb...
متن کاملIs COMT a susceptibility gene for schizophrenia?
Catechol-O-methyl transferase (COMT) is a catabolic enzyme involved in the degradation of a number of bioactive molecules; of principal interest to psychiatry, these include dopamine. The enzyme is encoded by the COMT gene. COMT is located (along with 47 other genes) in a fragment of chromosome 22q11 which when deleted results in a complex syndrome, the psychiatric manifestations of which inclu...
متن کاملEvidence of novel neuronal functions of dysbindin, a susceptibility gene for schizophrenia.
Genetic variation in dysbindin (DTNBP1: dystrobrevin-binding protein 1) has recently been shown to be associated with schizophrenia. The dysbindin gene is located at chromosome 6p22.3, one of the most promising susceptibility loci in schizophrenia linkage studies. We attempted to replicate this association in a Japanese sample of 670 patients with schizophrenia and 588 controls. We found a nomi...
