Impartment component in this network were coregulated at the gene expression level. Pearson's correlation coefficients between genes were performed. NRG1 and DLG4 showed the strongest correlation 0.76 among these genes. NRG1, DLG4 and NMDA receptor (GRIN complex) genes also showed strong correlation (correlation coefficients above or equal to 0.64) to each other. Black line represent the correlation of gene expression is ≧0.5. The dotted line represent the correlation value is <0.5. These highly correlated gene pairs implies that their protein products may also work together coordinately.
