We have recently reported the first case of mutation in the core promoter sequence of the human calreticulin gene in a family case of schizoaffective disorder. Remarkably, this gene coincides with a region of suggested linkage at 19p13.2, identified in a whole genome scan [Hamshere et al. (2005); Arch Gen Psychiatry 62;1081-1088]. The identified mutation was located at the conserved position -48 from the transcription start site, and was shown to be of functional effect, resulting in the aberrant expression of the gene. Following screening of the gene in 60 independent cases of schizoaffective disorder, we report novel germ-line mutations at positions -205 C > T and the conserved exon 5 (c: 682 C > T, pro228ser) in two unrelated cases of schizoaffective disorder. These mutations were disease-specific, and as for the -48 G > C mutation, neither was detected in a control population of 370 individuals, indicating a contribution of 3.17% in this sample series. To our knowledge, this is the first instance of disease-specific mutations in schizoaffective disorder, which warrants systematic screening of the regulatory and coding regions of the calreticulin gene in this disorder.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
