El gen involucrado en el síndrome es el PTCH1, el cual es responsable por garantizar que las células normales del organismo no se multipliquen con demasiada rapidez. Evans DG, Farndon PA. Nevoid Basal Cell Carcinoma Syndrome.
Quand il est fonctionnel, ce gène a pour fonction d'empêcher le développement de tumeurs ; on dit qu'il est un « suppresseur de tumeurs ». doi: 10.1038/ejhg.2011.9.

Birth incidence and prevalence of tumor-prone syndromes: estimates from a UK family genetic register service. Inheritance was autosomal dominant. Les personnes atteintes par ce syndrome ont donc plus de risques de développer des tumeurs et autres complications. Am J Med Genet A. The risk for ovarian tumors and skin cancer is increased with basal cell nevus syndrome (also called Gorlin syndrome or nevoid basal cell carcinoma), a rare autosomal dominant cancer genetic syndrome. Users with questions about a personal health condition should consult with a Bale AE, Yu KP. Sa prévalence dans la population générale est estimée à 1/14 300. Le nombre de cas est, en effet, estimé entre 1 sur 50 000 et 1 sur 1 000 000. Le cancer médullaire de la thyroïde (CMT) est un cancer rare qui se développe aux dépens des cellules C parafolliculaires thyroïdiennes responsables de la sécrétion de calcitonine. Le syndrome de Gorlin est connu sous diverses appellations : naevomatose basocellulaire ou syndrome de Gorlin-Goltz. Madras J, Lapointe H. Keratocystic odontogenic tumour: reclassification of the odontogenic keratocyst from cyst to tumour. In people with Gorlin syndrome, the type of cancer diagnosed most often is basal cell carcinoma, which is the most common form of skin cancer. Benign tumors (The prevalence of MEN2B is not well established, but has been derived from other epidemiological considerations as 1 in 600,000Unlike Marfan syndrome, the cardiovascular system and the lens of the eye are unaffected.Histologically, neuromata contain a characteristic adventitious plaque of tissue composed of About half of cases are inherited from a parent as an MEN2B should be entertained as a diagnosis whenever a person is found to have either medullary thyroid carcinoma or pheochromocytoma. Dans le cas du syndrome de Gorlin, il est rendu inopérant par la mutation. 2005 Mar;17(2):160-6. Review. Seattle (WA): University of Washington, Seattle; 1993-2017. MEN 2B typically manifests before a child is 10 years old. Goltz syndrome is a rare genetic condition characterized by involvement of the skin, skeletal system, eyes, and face. The range is quite variable, however: death early in childhood can occur, and a few untreated persons have been diagnosed in their 50s.Because prophylactic thyroidectomy improves survival, blood relatives of a person with MEN2B should be evaluated for MEN2B, even if lacking the typical signs and symptoms of the disorder.
Nevoid basal cell carcinoma (Gorlin) syndrome. They reported a family in which both father and son had basal cell nevi, with the son also having medulloblasto… Multiple endocrine neoplasia type 2B is a genetic disease that causes multiple tumors on the mouth, eyes, and endocrine glands.It is the most severe type of multiple endocrine neoplasia, differentiated by the presence of benign oral and submucosal tumors in addition to endocrine malignancies. 2010 Feb;152A(2):327-32. doi: 10.1002/ajmg.a.33139. Son incidence en pathologie nodulaire thyroïdienne se situe aux alentours de 1-2 %. High A, Zedan W. Basal cell nevus syndrome.
