Reduced fecundity, associated with severe mental disorders, places negative selection pressure on risk alleles and may explain, in part, why common variants have not been found that confer risk of disorders such as autism, schizophrenia and mental retardation. Thus, rare variants may account for a larger fraction of the overall genetic risk than previously(More)
From October 1, 1980 to April 20, 1981, 207 patients were admitted to the Department of Psychiatry, Odense University Hospital, after attempting suicide. Information on physical, mental and social conditions was collected. The patients were then followed for 5 years, to register subsequent suicidal behaviour and to try to identify relevant factors for(More)
BACKGROUND Protein encoding genes have long been the major targets for research in schizophrenia genetics. However, with the identification of regulatory microRNAs (miRNAs) as important in brain development and function, miRNAs genes have emerged as candidates for schizophrenia-associated genetic factors. Indeed, the growing understanding of the regulatory(More)
Oxidative stress could be involved in the pathophysiology of schizophrenia, a major psychiatric disorder. Glutathione (GSH), a redox regulator, is decreased in patients' cerebrospinal fluid and prefrontal cortex. The gene of the key GSH-synthesizing enzyme, glutamate cysteine ligase modifier (GCLM) subunit, is strongly associated with schizophrenia in two(More)
The Faroe Islands are a small group of islands in the North Atlantic Ocean, situated between Norway, Iceland and Scotland. The origin of the population is thought to be a mixture of Norwegian, Danish and British. The islands were populated at the same time as Iceland, i.e. around 1100 years ago, and the size of the population was around, and occasionally(More)
Patients with schizophrenia (n=11) and bipolar affective disorder (n=17) from the relatively isolated population of the Faroe Islands were genotyped for 34 polymorphic markers on chromosome 4 in a search for allelic association and haplotype sharing among distantly related patients. When considering bipolar patients only, there was no clearcut support for(More)
Repetition after attempted suicide is high but only few effect studies have been carried out. The Baerum Model from Norway offers practical and affordable intervention for those not being offered psychiatric treatment. During a period from 2005-2007, all attempted suicide patients except those with major psychiatric diagnoses (schizophrenia, bipolar(More)
The isolated population of the Faroe Islands has a history of recent expansion after being limited to a small size for centuries. Such an isolated population may be ideal for linkage disequilibrium mapping of disease genes if linkage disequilibrium (LD) extends over large regions. Analyses of 18 markers on 12q24.3, spanning a region of 4.3 Mb (16 cM),(More)
Repetition after attempted suicide is high with only limited research been put into effect studies. The Baerum-model from Norway offers a practical and affordable intervention. Our aim was to study the acceptability and effectiveness of a Baerum-model like intervention after attempted suicide using a quasi-experimental design. During a period in 2004,(More)
Serotonin (5-hydroxytryptamin; 5-HT) alternations has since long been suspected in the pathophysiology of schizophrenia. Tryptophan hydroxylase (tryptophan 5-monooxygenase; TPH) is the rate-limiting enzyme in the biosynthesis of 5-HT, and sequence variation in intron 6 of the TPH1 gene has been associated with schizophrenia. The minor allele (A) of this(More)
