Abstract

Purpose

Papillon-Lefèvre syndrome (PLS) is a rare autosomal recessive disorder that involves palmoplantar keratosis (PK) and severe aggressive periodontitis. Cathepsin C (CTSC) gene mutations are etiologic for PLS, with more than 60 different mutations reported in different ethnic groups worldwide. The purpose of this study was to report a novel cathepsin C mutation in a Brazilian patient.

Methods

A 4-year-old boy presented with aggressive periodontitis, recession, missing teeth, and hyperkeratosis of the palms of hands and soles. Peripheral blood samples were obtained from family members for genomic DNA isolation. The coding region and exon/intron boundaries of the CTSC gene were amplified and sequenced.

Results

The patient had a PLS phenotype, which included PK and early-onset severe periodontitis. Sequence analysis showed a novel CTSC mutation (c.267–268del) present in the homozygous state.

Conclusion

This report described a novel mutation in a family with Brazilian Papillon-Lefèvre syndrome and presented a review of all cathepsin C (65) mutations reported to date.
