A re-review of the association between the NOTCH4 locus and schizophrenia. Review uri icon

Overview

abstract

  • NOTCH4 has long been identified as a candidate susceptibility gene for schizophrenia, but the collective body of genetic association studies of this gene has been less than conclusive. Recently a variant in NOTCH4 was implicated as one of the most reliably associated polymorphisms observed in a genome-wide association scan of the disorder, and the collective evidence for this polymorphism now surpasses criteria for genome-wide significance. To place these developments in context, we now summarize the initial work identifying NOTCH4 as a candidate gene for schizophrenia. The results of the genome-wide association studies that have confirmed this as a risk gene, and novel bioinformatics analyses that reveal potential functional profiles of the most likely risk-conferring polymorphisms. These analyses suggest that the NOTCH4 polymorphisms most strongly associated with schizophrenia exert their effects on susceptibility by altering the efficiency and/or alternative splicing of Notch4 transcripts. Further experimental evidence should be pursued to clarify the NOTCH4-regulated molecular and cellular phenotypes of relevance to the disorder, and the functional consequences of the implicated polymorphisms in the gene.
