ABSTRACT

Objective: To detect the SMO mutations in odontogenic keratocyst (OKC) and to explore the mechanism behind. Methods: Patients with OKC who received treatment in the Department of Oral and Maxillofacial Surgery, School and Hospital of Stomatology,Peking University, from September 2012 to June 2017 were enrolled. OKC samples from 10 patients diagnosed as naevoid basal cell carcinoma syndrome (NBCCS)-related OKC (4 females and 6 males) and 20 patients diagnosed as sporadic OKC (7 females and 13 males) were collected. Genomic DNAs were extracted from fibrous capsules and epithelial lining respectively. SMO mutations were detected and analyzed by Sanger sequencing. Results: Three SMO mutations were found in one NBCCS-associated OKC who carrying c.2081C>G (p.P694R) mutation) and two sporadic OKC who carrying c.907C>T (p.L303F) mutation and c.1247_1248delinsAA (p.G416E), respectively), among which the first two mutations were novel mutations that had not been reported before. Besides, two mutations in sporadic OKC were not paired with PTCH1 mutations. Conclusions: In addition to PTCH1 gene mutations, SMO gene mutations also exist in OKC which might be related to the development of OKC.

ABSTRACT

RESUMEN El síndrome Gorlin (SG) es una condición genética, con patrón de herencia autosómico dominante, con penetrancia completa y expresividad variable, debida a mutaciones germinales en los genes PTCH1 o SUFU, los cuales son componentes de la vía molecular Sonic hedgehog. El SG se caracteriza por la presencia de múltiples carcinomas de células basales nevoides, quistes odontogénicos, calcificación de la hoz del cerebro y lesiones en sacabocado en palmas y plantas. Este es el primer reporte de casos en el Perú sobre pacientes con SG, que cuentan con evaluación y asesoría genética. Presentamos dos casos de SG que cumplen criterios clínicos del síndrome y una revisión de la literatura.


ABSTRACT Gorlin syndrome (GS) is a genetic disorder with an autosomal dominant inheritance pattern, with complete penetrance and variable expressivity. GS is caused by germline mutations in the genes PTCH1 or SUFU, which are components of the Sonic hedgehog molecular pathway. GS is characterized by the presence of multiple nevoid basal cell carcinomas, odontogenic cysts, calcification of the brain sickle, and lesions in the palms and soles. This study is the first to report cases in Peru of patients with GS who underwent genetic evaluation and counseling. We present two GS cases that meet the clinical criteria for the syndrome and review the literature

ABSTRACT

Este síndrome fue escrito en 1960 por Robert J Gorlin, patólogo bucalinvestigador formado en Minnesota y por Robert W Goltz, dermatólogo. Es un trastorno autosómico dominante ocasionado por el gen Patched 1 (PTCH1) que se ubica en el cromosoma 9q223, caracterizado por defectos en el desarrollo y alta predisposición al cáncer. La prevalencia es de 1/56,000 y 1/221,000 pacientes. El padecimiento se caracteriza por desarrollo de carcinomas basocelulares, queratoquistes odontogénicos y malformaciones esqueletales. Debido a su alta predisposición al desarrollo de carcinomas basocelulares agresivos, debe diagnosticarse temprana y oportunamente para un pronóstico favorable.


Robert Gorlin a mouth researcher trained pathologist Minnesota andRobert Goltz a dermatologist described this syndrome in 1960. It is anautosomal dominant disorder, caused by the Patched 1 gene (PTCH1)located on chromosome 9q223 characterized by developmental defectsand a high predisposition to cancer. The incidence is 1/56,000 and1/221,000 patients. The condition is characterized by the developmentof basal cell carcinomas, odontogenic keratocystic and skeletalmalformations. Due to its high predisposition to the development ofaggressive basal cell carcinomas should be early and timely diagnosisfor a favorable prognosis.

ABSTRACT

El síndrome del carcinoma basocelular nevoide (SCBCN) o de Gorlin-Goltz es un raro desorden autosómico dominante con un amplio espectro de manifestaciones clínicas. El signo cardinal es la presencia de múltiples carcinomas basocelulares (CBCs) y su ausencia demora el diagnóstico. Presentamos un adolescente de 14 años con diagnóstico de SCBCN por la presencia de queratoquistes odontogénicos, hiper­telorismo, macrocefalia y agenesia del cuerpo calloso pero sin lesiones cutáneas. La madre, de 43 años, tiene diagnóstico de SCBCN y no presenta CBCs. Para completar el estudio se realizó secuenciación bidireccional y Multiplex Ligation dependent Probe Amplification (MLPA) en sangre periférica para buscar mutaciones en PTCH1, principal gen responsable del síndrome. Se encontró una mutación germinal novel en el paciente y la madre: una duplicación de 25 pb en el exón 10 (c.1375dupl25bp). El análisis bioinformático predijo un corrimiento del marco de lectura y un codón stop prematuro, que produciría una proteína trunca más corta que lo normal. Nuestros resultados sugieren que el estudio clínico y genealógico completo con análisis genético es fundamental para la detección temprana de casos como el presente.


Nevoid Basal Cell Carcinoma Syndrome (NBCCS) or Gorlin-Goltz syndrome is a rare autosomal dominant disorder, mainly due to PTCH1 gene mutations, that comprises a broad spectrum of clinical manifestations. The presence of multiple basal cell carcinomas (BCCs) is a cardinal sign in NBCCS, therefore cases in which BCCs are absent entails a delay in the diagnosis.We present a 14 years old boy with a clinical diagnosis of NBCCS by the presence of odontogenic cysts, hypertelorism, macrocephaly, and corpus callosum agenesia, but with absence of skin lesions. His 43 years old mother has NBCCS diagnosis and no history of BCCs. For a deeper study, PTCH1 mutation screening from peripheral blood samples were performed by both bidirectional sequencing and multiplex ligation dependent probe amplification (MLPA) techniques. The proband and his mother carry 25 pb duplication in exon 10 (c.1375dupl25bp) that causes a reading frameshift with a premature stop codon. Bioinformatics analysis predicted that this mutation results in a truncated protein shorter than normal. Our results suggest that complete clinical and genealogical studies accompanied by genetic analysis are essential in the early detection of the NBCCS cases such the one presented here.

ABSTRACT

El síndrome de nevus de células basales (SNCB) es un desorden autosómico dominante en el que aparecen múltiples alteracines, las más frecuentes son la presencia de carcinoma de células basales nevoides en la piel, queratoquistes odontogénicos en los huesos maxilares y otras alteraciones óseas. Presentamos un caso de SNCB en el que se valora la importancia de la historia clínica, examen radiológico, estudio histopatológico, estudio genético y el papel del odontólogo, ya que su diagnóstico se pudo establecer en base a los queratoquistes odontogénicos. Se discuten los hallazgos contrastándolos con los obtenidos por los autores

ABSTRACT

The Nevoid Basal-Cell Carcinoma Syndrome (NBCC), or as it is also referred to, basal-cell nevus syndrome or Gorlin-Goltz syndrome, is characterized by multiple early-appearing basal cell carcinomas, keratocytosis of the mandible, and anomalies of the ocular, skeletal reproductive system. We describe four patients in the same family, all of them possessing a large number of skin tumors associated with other typical clinical and X-Ray anomalies of NBCC. The definitive treatment of NBCC has yet to be established, however, early diagnosis is very important as well as the periodical follow-up examination of ten patients, mainly due to the transformations in the skin lesions that may occur.
