Identification of a novel cathepsin C mutation (p.W185X) in a Brazilian kindred with Papillon-Lefèvre syndrome.
Papillon-Lefèvre syndrome (PLS) is an autosomal recessive palmoplantar keratoderma caused by cathepsin C (CTSC) gene mutations. This study reports CTSC mutational and enzyme analyses in a consanguineous Brazilian family with PLS, representing the first enzymatic analysis of a Brazilian kinship with PLS. This family segregates a novel PLS-related mutation, p.W185X, that is associated with a complete loss of enzymatic activity.
