CD4 and pachyonychia congenita: Seven genes, including CD4 (HR = 1.600, P = 0.028, Figure 5A), CD163 (HR = 2.000, P = 0.001, Figure 5B), CSF1R (HR = 1.700, P = 0.017, Figure 5C), CTSC (HR = 1.500, P = 0.045, Figure 5D), MGP (HR = 1.600, P = 0.023, Figure 5E), PTGDS (HR = 0.590, P = 0.014, Figure 5F), and C7 (HR = 0.630, P = 0.029, Figure 5G) were significantly correlated with RFS of PC patients.
