2 Figure 1 Clinical features of pachyonychia congenita (PC). Plantar keratoderma and nail dystrophy in PC patients with known keratin mutations. Mutations are annotated. Note the variation in severity and clinical appearance of these features.

4 Figure 3 Kyte–Doolittle hydrophilicity analysis of normal and mutant K6a V2 domain. (a) The normal K6a V2 domain consists of alternating hydrophobic and hydrophilic sequences, followed by a short hydrophilic C terminus, whereas (b) the mutant V2 domain is almost completely hydrophilic.
