Through bioinformatic technologies, our research indicates that 10 HUBgenes (ZNF595, PLXDC1, FNBP1L, KLRB1, NRCAM, PPCDC, C9orf139, SIGLEC17P, RRAS2 and DPRXP4) are significantly associated with IDD, providing more evidence about the vital role of ZNF595 and RRAS2 in IDD. The gene discussed is PPCDC; the disease is intervertebral disk degenerative disorder.
