Abstract:
Several lines of evidence from animal and genetic analyses showed that the calcineurin A gamma subunit gene (PPP3CC) plays an important role in the pathogenesis of schizophrenia. Moreover, a recent large Japanese case-control study confirmed the genetic association of PPP3CC with schizophrenia. The symptoms of methamphetamine (MAP)-induced psychosis are similar to those of schizophrenia, suggesting that PPP3CC is an attractive candidate gene not only for schizophrenia, but also for METH-related disorders. In this study, we carried out a genetic association study of PPP3CC with MAP-use disorder in a Japanese population. We selected five haplotype-tagging SNPs from the aforementioned replication study and genotyped 393 samples (MAP abuse, 128; control, 265). We could not detect a significant association of all tagging SNPs with each condition. In conclusion, our data suggest that PPP3CC does not elevate the risk of MAP-use disorder in the Japanese population.
