The average MUC5AC+ goblet cell density was lower in acute SJS/TEN patients (50.11 ± 32.2 cells/mm2) than in healthy volunteers (72.33 ± 30.56 cells/mm2), but the difference was not statistically significant (P value > 0.05, Table 2). This evidence concerns the gene MUC5AC and Schwartz-Jampel syndrome.
