Common polygenic variation contributes to risk of schizophrenia and bipolardiso...
Purcell, S. M.; Wray, N. R.; Stone, J. L.; Visscher, P. M.; O'Donovan, M. C.; Sullivan, P. F.; Sklar, P.; Leader, S. M.; Ruderfer, D. M.; McQuillin, A.Schizophrenia is a severe mental disorder with a lifetime risk of about 1%, characterized by hallucinations, delusions and cognitive deficits, with heritability estimated at up to 80%. We performed a genome-wide association study of 3,322 European individuals with schizophrenia and 3,587 controls. Here we show, using two analytic approaches, the extent to which common genetic variation underlies the risk of sch...
Rare chromosomal deletions and duplications increase risk of schizophrenia
Craddock, N. J.; Gill, M.; Hultman, C. M.; Lichtenstein, P.; McQuillin, A.; Pato, Carlos N.; Ruderfer, D. M.; Owen, M. J.; St Clair, DavidSchizophrenia is a severe mental disorder marked by hallucinations, delusions, cognitive deficits and apathy, with a heritability estimated at 73–90% (ref. 1). Inheritance patterns are complex, and the number and type of genetic variants involved are not understood. Copy number variants (CNVs) have been identified in individual patients with schizophrenia and also in neurodevelopmental disorders, but large-scal...
