Journal ArticleDOI

Biological insights from 108 schizophrenia-associated genetic loci

Stephan Ripke, +354 more
- 24 Jul 2014 - 
TL;DR: 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.
Journal ArticleDOI

Familial Hemiplegic Migraine and Episodic Ataxia Type-2 Are Caused by Mutations in the Ca2+ Channel Gene CACNL1A4

TL;DR: A brain-specific P/Q-type Ca2+ channel alpha1-subunit gene, CACNL1A4, covering 300 kb with 47 exons is characterized, revealing polymorphic variations, including a (CA)n-repeat (D19S1150), a (CAG) n-repeat in the 3'-UTR, and different types of deleterious mutations in FHM and EA-2.
Journal ArticleDOI

Genetic relationship between five psychiatric disorders estimated from genome-wide SNPs

S. Hong Lee, +405 more
- 01 Sep 2013 - 
TL;DR: Empirical evidence of shared genetic etiology for psychiatric disorders can inform nosology and encourages the investigation of common pathophysiologies for related disorders.
Journal ArticleDOI

Large recurrent microdeletions associated with schizophrenia

Hreinn Stefansson, +81 more
- 11 Sep 2008 - 
TL;DR: In a genome-wide search for CNVs associating with schizophrenia, a population-based sample was used to identify de novo CNVs by analysing 9,878 transmissions from parents to offspring and three deletions significantly associate with schizophrenia and related psychoses in the combined sample.
Journal ArticleDOI

Genome-wide association study identifies five new schizophrenia loci

Stephan Ripke, +210 more
- 01 Oct 2011 - 
TL;DR: The authors examined the role of common genetic variation in schizophrenia in a genome-wide association study of substantial size: a stage 1 discovery sample of 21,856 individuals of European ancestry and a stage 2 replication sample of 29,839 independent subjects.
