For example, recent genetic studies have found schizophrenia-associated mutations in proteins common to CaMKII signaling, including Ca2+ channels (Cross-Disorder Group of the Psychiatric Genomics, 2013) and postsynaptic density (PSD) proteins (Fromer et al., 2014; Kirov et al., 2012). The gene discussed is CAMK2G; the disease is schizophrenia.
