CACNA1C and schizophrenia: Next to BPD, the rs1006737 SNP in CACNA1C was found to be a susceptible SNP in schizophrenia in separate studies, though with less statistical power compared to BPD, suggesting possible overlap of genetic risk for both diseases ( Moskvina et al., 2009; Green et al., 2010; Sullivan et al., 2012).
