Of note, the current microarray data (Supplementary Table S1) identified four gamma subunits of the L-type voltage-gated calcium channels to be down-regulated in PCP-SI rats, and single nucleotide polymorphisms in two of these (CACNG4 and CACNG6) have recently also been associated with schizophrenia (Guan et al., 2016). Here, CACNG4 is linked to schizophrenia.
