UCHL1 and laryngotracheoesophageal cleft: The results showed that the serum AAB concentrations of p53, PGP9.5, SOX2, GBU4-5, MAGEA1, and CAGE in the LC patients were markedly higher than those in the healthy controls (P = 0.042, P < 0.001, P = 0.046, P < 0.001, P < 0.001, and P < 0.001, respectively), but the expression level of GAGE7 in the LC group was similar to that of the healthy group (P = 0.844) (Figures 1(a)–1(g)).
