In the context of our finding, it is interesting to note that, a single polymorphism in the neuregulin-1 gene, a schizophrenia risk gene [55], has recently been reported to be associated with vGluT1 expression in human postmortem brains, with the at-risk allele predicting decreased expression of the glutamatergic marker [56]. The gene discussed is NRG1; the disease is schizophrenia.
