SCIENTIFIC LETTER TO THE EDITOR:

Novel Mutations in the Cathepsin C Gene in Patients with Pre-pubertal Aggressive Periodontitis and Papillon-Lefèvre Syndrome

B. Noack, H. Görgens, Th. Hoffmann, J. Fanghänel, Th. Kocher, P. Eickholz, and H.K. Schackert
The authors state that at least a subset of pre-pubertal aggressive periodontitis is due to mutations in the cathepsin C gene and therefore may be an allelic variant of Papillon-Lefèvre syndrome.
