The Papillon Lefevre syndrome (PLS)is characterized by periodontal diseaseaffecting both the deciduous as well asthe permanent dentition and hyperkera-tosis of the hands and feet (palmarplantar keratosis, PPK) (Papillon & Le-fevre 1924). The syndrome is thoughtto be the homozygous expression of anautosomal recessive trait transmittedwith an estimated frequency of 1-2 per-sons per million (Gorlin et al. 1964).The 2 major components of the syn-drome are known to occur as distinctdisease entities. Dermatological lesionssimilar to those seen in the syndromeare fairly commonly found as a separ-ate, genetically transmitted trait (Gold-smith & Thomas 1992), suggesting amultigenetic etiology for PLS (Hart &Shapira 1994). Destructive adult typeperiodontitis is a relatively common

disease, affecting approximately 30% ofthe working adult American population(Miller et al. 1987). Periodontitis is farrarer in the younger population whereit occurs as Early Onset Periodontitis ofthe localized or generalized form affect-ing approximately 0.6% of the popula-tion (Loe & Brown 1991). Destructiveperiodontal disease affectmg the de-ciduous dentition has otily been de-scribed in a few isolated case reports.(Page et al. 1983, Spector et al. 1985,Page et al. 1985). While there is someevidence for a genetic component toadult periodontitis, a form of early on-set periodontitis. Juvenile Periodontitis,has been shown to likely be inherited asan autosoma! dominant trait (VanDyke et al. 1985, Hart et al. 1992, Mar-azita et al. 1994).

dermatological symptoms startedaround the 3rd decade (Brown et al,1993), The nature of the periodontaldisease affecting the permanent teethalso varies from an acute fulminatingtype infection affecting the teeth ontheir eruption and resulting in theirearly loss m spite of treatment (Shamset al. 1984, Celenligil et al. 1992, Hane-ke et al 1975, Preus 1988, Van Dyke etai. 1984, Schroeder etal. 1983), to a dis-ease recognized only later in life aroundthe 3rd decade and which has a moresubdued clinical presentation (Brown etal, 1993, Willet et al. 1985). There arealso those cases which appear to re-spond to periodontai therapy haltingthe disease progression (Tinanoff et al.1986, Preus & Gjermo 1987, Ishikawaet al. 1994).

These descriptions of the syndrometogether with the fact that the twomajor manifestations of disease (PPKand periodontal disease) occur as inde-pendent diseases raise the difficulty ofhaving to differentiate between a rare

genetic syndrome and the possible se-rendipitous association of 2 separatedisease entities. The purpose of this re-port is to present two unrelated familieswith PLS in which there is partial ex-pression of the cardinal features of thesyndrome.

Case ReportsCase no. 1

A large family of Jews from Cochin, In-dia with 15 members affected by Papil-lon-Lefevre syndrome has been exten-sively studied over the years (Shoshanet al. 1970, Hacham-Zadeh et al. 1979,Shapira et ai. 1985). Because of the geo-graphical and religious isolation of thiscommunity in India prior to their immi-gration to Israel, extensive intermar-riage amongst the family members was

culturally acceptable. Fig. 1 illustratesthe pedegree of the nuclear family re-ported here.

One member of the family, a 19-year-old male (IL-9). expresses only the der-matological lesions without any peri-odontal involvement. The 1st signs ofthe disease occurred on the soles of thefeet at approximately 3 months of ageas single small maccular lesions whichspread to involve the entire plantar sur-face. At approximateiy 3-4 years of age,the paimar surfaces became involvedand to date the disease involves the dor-sum of the hands and feet as weil asother skin surfaces including the eibowsand the knees (Fig. 2). The 30 teethpresent in his mouth have intact peri-odontium with pocket probing depthsthat do not exceed 4 mm and no attach-ment loss (Fig. 3). He has a mild gingi-

vitis. Of the remaining 5 siblings. 1brother, now deceased, suffered fromboth dermatological and periodontallesions and had lost his teeth by the ageof 13 years. A sister had lost her teethby the age of 15 years and has hyper-keratosis affecting only the plantar sur-faces of her feet.

Case no. 2

A German family consisting of bothparents and 5 children has been fol-lowed over the past 15-20 years. (Fig.4). There was no history of consanguin-ity between the parents. According tothe family dentist, although both par-ents are edentulous they had not shownsigns of an aggressive form of peri-odontitis and had lost their teeth be-cause of severe caries. The mothershowed signs of abnormal keratiniz-ation of her skin from childhood. Ofthe 5 children, 4 had lost their teeth al-most immediately after eruption of thepermanent dentition (Fig. 5). 3 of these

4 siblings also showed signs of palmar-plantar-hyperkeratosis (Eig. 6|. The 4thchild was free of any signs of hyperkera-tinization at the time of the clinicalexamination. The 5th child expressedonly the dermatological symptomswithout periodontitis (Eig. 7). Com-pared to other reports of PLS, thehyperkeratinization of this Germanfamily was mild. Eig. 8 follows the pro-gression of the syndrome radiographi-cally, in the youngest member of thefamily, over a 16-year period. Of inter-

est to us in this report are the 2 siblingswith discordant expression of the cardi-nal features of PLS. In one, only thePPK. symptoms are present, while inthe other, only the periodontal symp-toms are present.

Discussion

The 2 families described illustrate bothvariable and discordant expression ofthe two cardinal features of PLS. Thefindings corroborate previous reports ofpartial expression of periodonta! anddermatological manifestations of PLS(Bullon et al. 1993. Shams el din et al.1984). The discordant expression ob-served suggests several possible geneticetiologies for PLS. Does PLS representthe variable clinical expression of asingle gene defect or is PLS a multi gen-etic disease representing co-expressionof two closely linked loci. Both hall-marks of PLS (severe onset peri-odontitis leading to edentulism and pal-mar plantar hyperkeratosis) are knownto exist as independent traits, yet bothare uncommon. Severe early onset peri-odontitis leading to premature edentul-

ism of both dentitions is particularelyrare. This suggests that the chance oc-currence of these two traits in the nu-merous families reported to date is un-likely (Goriin et al. 1964, Haneke 1979),and argues for another explanation.PLS is an autosomai recessive trait, pre-sumed to result in individuals homo-zygous for the disease locus. However.the disease alleles may not be identical.Allelic heterozygosity could account forsome of the clinical variability observedparticularely in cases where consan-guinity is absent. In the case of theCochin family, the disease alleles are be-lieved to be identical by descent. An-other possibility is that of manifestationof heterozygosity. Kotzot & Pfeiffer(1993) noted that occasional manifes-tation of heterozygosity for autosomalrecessive disorders has been reported.They presented a case of a presumedheterozygous parent of PLS affected in-dividuals presenting with eariy toothloss. The reported abnormal keratiniz-ation of the probands mother in theGerman family (Eig. 2) is interesting inthis regard and may represent a mani-festation of heterozygosity in PLS.

Variable clinical expression of singlegene mutations is known to occur, forexample, in ectodermal dysplasia, Du-cijenne muscular dystrophy and cysticfibrosis. In the case of Duchenne mus-cuiar dystrophy, it is beheved that amajor iocus gene (unlinked to the dis-ease gene) influences dystropin ex-pression. Such epistatic interactions be-tween a disease gene and other (notnecessariiy iinked) modifying genescould be present in PLS. and result invariable clinical expression of the syn-drome. Olher possible modifying infiu-ences include genetic imprinting, partic-ularely in cases of somatic heterozygos-ity of the mutative aliele. Genetic

''imprinting has nol been evaluated inPLS. but differential methylation pat-terns of disease and modifying alielescould influence disease expression. Weare currently conducting genetic linkageanalyses for these families. Resuits ofthese studies may allow us to determinethe genetic etiology of PLS.
