A significant increase in protein levels of Homer1a was detected in schizophrenia subjects relative to controls, after co-varying for freezer storage time (+42.92%; F1,34=9.751, P=0.004; Figure 2a), which was a variable that correlated with Homer1a protein expression in control subjects only (r=0.545, P=0.013; Supplementary Table 1). The gene discussed is HOMER1; the disease is schizophrenia.
