Molecular Genetic Pathogenesis KRT5 and KRT14 are expressed in the basal epidermolisus of the epidermis the innermost layerwhere their protein products form heterodimeric molecules that assemble into the intracellular keratin intermediate filament network.


Within basal keratinocytes, plectin is localized to the inner plaques of the hemidesmosomes, which are hypoplastic and show poor association with keratin filaments.
