KRT14 and epidermolysis bullosa simplex: Previous studies have shown that the mutation of KRT14 and KRT5 causes epidermolysis bullosa simplex (Bolling et al., 2011; Jankowski et al., 2014); KRT14 may regulate the keratin turnover required for keratinocyte differentiation by interacting with receptor-interacting protein kinase 4 (RIPK4) (Smer et al., 2019).
