  • Gene expression imputation across multiple brain regions provides insights into schizophrenia risk

    • Transcriptomic imputation approaches combine eQTL reference panels with large-scale genotype data in order to test associations between disease and gene expression. These genic associations could elucidate signals in complex genome-wide association study (GWAS) loci and may disentangle the role of different tissues in disease development. We used the largest eQTL reference panel for the dorso-lateral prefrontal cortex (DLPFC) to create a set of gene expression predictors and demonstrate their utility. We applied DLPFC and 12 GTEx-brain predictors to 40,299 schizophrenia cases and 65,264 matched controls for a large transcriptomic imputation study of schizophrenia. We identified 413 genic associations across 13 brain regions. Stepwise conditioning identified 67 non-MHC genes, of which 14 did not fall within previous GWAS loci. We identified 36 significantly enriched pathways, including hexosaminidase-A deficiency, and multiple porphyric disorder pathways. We investigated developmental expression patterns among the 67 non-MHC genes and identified specific groups of pre- and postnatal expression.

  • Biological insights from 108 schizophrenia-associated genetic loci
  • 2014
  • Ingår i: Nature. - 0028-0836. ; 511:7510, s. 421-427

    • Schizophrenia is a highly heritable disorder. Genetic risk is conferred by a large number of alleles, including common alleles of small effect that might be detected by genome-wide association studies. Here we report a multi-stage schizophrenia genome-wide association study of up to 36,989 cases and 113,075 controls. We identify 128 independent associations spanning 108 conservatively defined loci that meet genome-wide significance, 83 of which have not been previously reported. Associations were enriched among genes expressed in brain, providing biological plausibility for the findings. Many findings have the potential to provide entirely new insights into aetiology, but associations at DRD2 and several genes involved in glutamatergic neurotransmission highlight molecules of known and potential therapeutic relevance to schizophrenia, and are consistent with leading pathophysiological hypotheses. Independent of genes expressed in brain, associations were enriched among genes expressed in tissues that have important roles in immunity, providing support for the speculated link between the immune system and schizophrenia.

  • Benchmarks for Cystic Fibrosis carrier screening: A European consensus document
  • 2010
  • Ingår i: Journal of Cystic Fibrosis. - Elsevier. - 1873-5010. ; 9:3, s. 165-178
  • Forskningsöversikt (refereegranskat)abstract
    • This paper presents an overview of the conclusions from an international conference convened to address current issues related to the provision of Cystic Fibrosis carrier screening within Europe. Consensus was not aimed at stating whether such a programme should be implemented. Instead the focus was to provide a framework for countries and agencies who are considering or planning its establishment. The general principles and target population of Cystic Fibrosis carrier screening, advantages and disadvantages, health economics, monitoring and future evaluative and research directions were covered. A range of screening strategies have been assessed and compared: pre-conceptional and prenatal screening; individual and couple screening; sequential and simultaneous sampling or testing. Furthermore, technical issues were examined with respect to the choice of the panel of mutations, its detection rate, sensitivity, management of intermediate 'at-risk' couples, screening approach to different populations and ethnic minorities, and assurance of laboratory quality control. The consensus statement also aims to establish the benchmarks for communicating with health care providers, the general public and potential and actual participants before and after the genetic test.
