Several proteins altered by Igf2 enhancer deletion had been found dysregulated in the synaptosomal proteome of schizophrenia patients36, including genes affecting synaptic plasticity and neurotransmitter release, such as calcium/calmodulin dependent protein kinase II alpha (Camk2a), myristoylated alanine-rich C-kinase substrate (Marcks), and alpha-synuclein (Snca) (Fig. 4c). The gene discussed is IGF2; the disease is schizophrenia.
