Nevoid basal cell carcinoma syndrome: molecular biology and new hypotheses.

To understand the molecular biology of the nevoid basal cell carcinoma syndrome, the hedgehog signaling network is explained. The syndrome is caused by mutations in patched, a tumor suppressor gene. A single point mutation in one patched allele may be responsible for the malformations found in the syndrome. Inactivation of both patched alleles results in the formation of tumors and cysts (basal cell carcinomas, odontogenic keratocysts, and medulloblastomas). Several new hypotheses are proposed to account for a minority of nevoid basal cell carcinoma syndrome patients. Evidence is provided to suggest that these hypotheses deserve to be investigated.     

Nevoid Basal Cell Carcinoma Syndrome: A Case Report and Review

Nevoid basal cell carcinoma syndrome, a rare autosomal dominant disorder, comprises of a number of abnormalities such as multiple nevoid basal cell carcinomas, skeletal abnormalities and multiple keratocystic odontogenic tumors. Diagnosis may be difficult because of the variability of expressivity and different ages of onset for different traits of this disorder. The dental clinician may be the first to encounter and identify this syndrome, when the multiple cysts like radiolucencies are discovered on panoramic view. This article reports a case of Nevoid basal cell carcinoma syndrome and provides an overview on diagnosis and management.     

Odontogenic keratocysts in a 5-year-old: initial manifestations of nevoid basal cell carcinoma syndrome

The purpose of this paper is to report the occurrence of odontogenic keratocysts in a young child. Odontogenic keratocysts are one of the principal features of nevoid basal cell carcinoma syndrome. Their occurrence in this syndrome is usually during the second or third decades of life. This report describes the occurrence of odontogenic keratocysts in a 5-year-old, which proved to be the initial presentation of nevoid basal cell carcinoma syndrome and highlights the need to consider this syndrome as a possible diagnosis in all cases of odontogenic keratocysts.     

Expression of cell cycle and apoptosis-related proteins in sporadic odontogenic keratocysts and odontogenic keratocysts associated with the nevoid basal cell carcinoma syndrome.

Odontogenic keratocysts are occasionally (4-5%) associated with the nevoid basal cell carcinoma syndrome, a pleiotropic, autosomal disorder presenting a spectrum of developmental abnormalities and a predisposition for the development of different neoplasms. The aim of this study was to establish whether keratocysts showing clinically aggressive behavior associated with nevoid basal cell carcinoma syndrome reflect differences in cellular proliferation rate and/or in the expression of oncoproteins and tumor suppressor genes. For this reason, formalin-fixed paraffin-embedded sections of odontogenic keratocysts associated with the nevoid basal cell carcinoma syndrome (16 cases) and sporadic odontogenic keratocysts (16 cases) were compared for expression of proliferating cell nuclear antigen (PCNA) and p53, bcl-2, and bcl-1 (cyclin D1) onco-proteins. Most of the epithelial lining of odontogenic keratocysts associated with the nevoid basal cell carcinoma syndrome showed nuclear immunopositivity for p53 protein and overexpression of cyclin D1 with various degrees of staining intensity. All sporadic odontogenic keratocysts were negative for p53 and cyclin D1. The expressions of bcl-2 oncoprotein were found to be substantially similar between the two groups of lesions, with a cytoplasmic immunopositivity localized only in the resting reserve basal layer of the epithelium. PCNA expression showed no statistically significant difference between the two groups of lesions. In conclusion, the finding of cyclin D1 and p53 overexpression in odontogenic keratocysts associated with the nevoid basal cell carcinoma syndrome could be considered a hallmark of a mutated cellular phenotype, thus leading to the hypothesis that their aggressive clinical behavior could be due to a dysregulation of the expression of cyclin D1 and p53 proteins, involved in a check-point control of cellular proliferation.     

PTCH germline mutations in Chinese nevoid basal cell carcinoma syndrome patients

OBJECTIVES: PTCH, the human homologue of the Drosophila segment polarity gene, patched, has been identified as the gene responsible for nevoid basal cell carcinoma syndrome. The aim of this study was to investigate PTCH gene mutation in Chinese patients with nevoid basal cell carcinoma syndrome. MATERIALS AND METHODS: DNA was isolated from both odontogenic keratocyst tissue and peripheral blood of five patients with syndrome and one patient with only multiple odontogenic keratocysts, and mutational analysis of the PTCH gene performed by direct sequencing after amplification of all 23 exons by polymerase chain reaction (PCR). RESULTS: A previously reported germline mutation (c.2619C>A) was identified in two familial cases involving the mother and the daughter, with the mother also carrying a novel somatic mutation (c.361_362insGAGC). Three novel germline PTCH mutations (c.1338_1339insGCG, c.331delG and c.1939A>T) were detected in three unrelated patients with syndrome. The patient with multiple odontogenic keratocysts who failed to fulfill the diagnostic criteria of the syndrome also carried a novel germline mutation (c.317T>G). CONCLUSION: The frequent germline PTCH mutations detected in our series provide further evidence for the crucial role of PTCH in the pathogenesis of nevoid basal cell carcinoma syndrome in Chinese.     

Contributions of PTCH gene variants to isolated cleft lip and palate.

OBJECTIVE: Mutations in patched (PTCH) cause the nevoid basal cell carcinoma syndrome (NBCCS), or Gorlin syndrome. Nevoid basal cell carcinoma syndrome may present with developmental anomalies, including rib and craniofacial abnormalities, and predisposes to several tumor types, including basal cell carcinoma and medulloblastoma. Cleft palate is found in 4% of individuals with nevoid basal cell carcinoma syndrome. Because there might be specific sequence alterations in PTCH that limit expression to orofacial clefting, a genetic study of PTCH was undertaken in cases with cleft lip and/or palate (CL/P) known not to have nevoid basal cell carcinoma syndrome. RESULTS: Seven new normal variants spread along the entire gene and three missense mutations were found among cases with cleft lip and/or palate. One of these variants (P295S) was not found in any of 1188 control samples. A second variant was found in a case and also in 1 of 1119 controls. The third missense (S827G) was found in 5 of 1369 cases and in 5 of 1104 controls and is likely a rare normal variant. Linkage and linkage desequilibrium also was assessed using normal variants in and adjacent to the PTCH gene in 220 families (1776 individuals), each with two or more individuals with isolated clefting. Although no statistically significant evidence of linkage (multipoint HLOD peak = 2.36) was uncovered, there was borderline evidence of significant transmission distortion for one haplotype of two single nucleotide polymorphisms located within the PTCH gene (p = .08). CONCLUSION: Missense mutations in PTCH may be rare causes of isolated cleft lip and/or palate. An as yet unidentified variant near PTCH may act as a modifier of cleft lip and/or palate.

Nevoid basal cell carcinoma syndrome (NBCCS) is characterised by skeletal anomalies, cutaneous basal cell carcinomas and multiple keratocysts. NBCCS is an autosomal dominant disorder, but can have a variable phenotypic penetration. NBCCS can also arise spontaneously. The prevalence is 1:60.000 and 50-65% of patients with NBCCS have affected family members. A recently diagnosed patient is presented and the manifestations of the syndrome are discussed.
