摘要
Background: Linkage studies have confirmed that chromosome 1q23.3 is a susceptibility locus for schizophrenia. It was then claimed that markers at the carboxyl-terminal PDZ ligand of neuronal nitric oxide synthase (CAPON) gene showed allelic association with schizophrenia in Canadian families. A second Chinese study found a base pair polymorphism at the CAPON gene also associated with schizophrenia. Methods: We attempted replication using eight markers from the Canadian study in a UK based sample of 450 cases and 450 supernormal controls. Results: We found no evidence for allelic or haplotypic association with schizophrenia for any of the markers found to be associated in the Canadian sample. Conclusions: The negative results might reflect genetic heterogeneity between the Canadian, Chinese and UK samples or be due to methodological problems. The present finding weakens the evidence that mutations or variation in the CAPON gene are causing genetic susceptibility to schizophrenia in European populations.
