Protein–protein interaction network with the genes associated with non-syndromic cleft palate only (NSCPO). Twenty out of 25 genes formed two nodes interconnected by a validated interaction between LRP6 and MTR. The first encompassed nine genes, including FTCD, MTHFD1, MTHFR, MTR, OFD1, SHMT1, TCN2, TCOF1, and TYMS (P < 1.0e-16), and the second node involved CDH1, COL2A1, COL11A1, COL11A2, CREBBP, GRHL3, LRP6, MSX1, SOX9, TBX1, and TBX22 (P < 1.0e-16). Both nodes were based on curated databases (light blue), experimentally (purple), gene neighborhood (green), gene fusions (red), gene co-occurrence (blue), text mining (light green), co-expression (black), and protein homology (violet). This analysis had an average confidence score of 0.588 (P < 1.0e-16), suggesting a low rate for false-positive interactions.
