DefinitionThis section has been translated automatically.
Autosomal recessive inherited keratinization disorder with diffuse transgressive palmoplantar keratoses, peridontitis, dental abnormalities, and susceptibility to infection.
EtiopathogenesisThis section has been translated automatically.
Mutations of the Papillon-Lefèvre syndrome gene(CTSC = Cathepsin C or PLS gene/gene locus: 11q14.1-q14.3). The mutations result in deficiency of a lysosomal protease (cathepsin C, see cathepsins below). Cathepsin C plays an important role in the activation of certain proteases involved in the phagocytosis of bacteria.
A variant of Papillon-Lefèvre syndrome, Haim-Munk syndrome is also caused by mutations in the CTSC gene.

Clinical featuresThis section has been translated automatically.
Integument: Transgressive diffuse palmoplantar keratosis, sharply demarcated redness of palmae and plantae spreading to dorsum of hands and feet, psoriasiform hyperkeratosis of elbows and knees, hyperhidrosis.
Extracutaneous manifestations: early caries, gingivitis, periodontopathy, alveolar atrophy, tooth loss in deciduous and permanent dentition (Giannetti L et al 2020).
Debility is possible
A slightly different phenotype is described as Haim-Munk variant with the same CTSC mutation. In addition to the PL symptoms, arachnodactyly, acroosteolysis, pes planus and deformities of the fingers are found.
