Although risk variations in CACNA1S and CACNA1F encoding CaV1.1 and CaV1.4 channels have been identified in GWAS and WES studies for BD and SCZ, we will not review them here because the expression of these two genes in the brain is extremely rare relative to the other CaV genes; therefore the links between their corresponding risk variations and psychiatric disorders are hard to infer [16]. This evidence concerns the gene CAV2 and psychiatric disorder.
