A risk score model of GILncSig based on the results of the multivariate Cox analysis regression coefficients was generated to predict the outcome of PC patients as follows: GILncSig = (−1.61 × expression value of AC087752.3) + (0.63 × expression value of AL121772.1) + (0.39× expression value of BX640514.2) + (0.02 × expression value of LINC01133) + (0.38× expression value of LYPLAL1-AS1). The gene discussed is LYPLAL1; the disease is pachyonychia congenita.
