          Abstract

          Neurofibromatosis, which was first described in 1882 by Von Recklinghausen, is a genetic disease characterized by a neuroectodermal abnormality and by clinical manifestations of systemic and progressive involvement which mainly affect the skin, nervous system, bones, eyes and possibly other organs. The disease may manifest in several ways and it can vary from individual to individual. Given the wealth of information about neurofibromatosis, we attempted to present this information in different ways. In the first part of this work, we present a chronological history, which describes the evolution of the disease since the early publications about the disorder until the conclusion of this work, focusing on relevant aspects which can be used by those wishing to investigate this disease. In the second part, we present an update on the various aspects that constitute this disease.

          A neurofibromatose, descrita inicialmente em 1882 por Von Recklinghausen, é uma doença genética caracterizada por uma anormalidade neuroectodérmica e por manifestações clínicas de envolvimento sistêmico e progressivo, que acometem principalmente a pele, o sistema nervoso, ossos, olhos e eventualmente outros órgãos, podendo apresentar uma grande diversidade de manifestações que variam de indivíduo para indivíduo. Diante da riqueza de informações encontradas a respeito da neurofibromatose, buscamos apresentá-la sob diversos aspectos, organizando os conhecimentos a respeito dessa doença. Na primeira parte desse trabalho, apresentamos um histórico cronológico, relatando a evolução dessa doença desde os primórdios das publicações a ela referentes até o momento do término desse trabalho, dando ênfase aos fatos relevantes ao seu conhecimento e que possam ser utilizados por aqueles que pretendam pesquisar a respeito dessa afecção. Na segunda parte, apresentamos uma atualização sobre os diversos aspectos que compõem essa doença.

            Proteins regulating Ras and its relatives.

            GTPases of the Ras superfamily regulate many aspects of cell growth, differentiation and action. Their functions depend on their ability to alternate between inactive and active forms, and on their cellular localization. Numerous proteins affecting the GTPase activity, nucleotide exchange rates and membrane localization of Ras superfamily members have now been identified. Many of these proteins are much larger and more complex than their targets, containing multiple domains capable of interacting with an intricate network of cellular enzymes and structures.

              Alteration in a new gene encoding a putative membrane-organizing protein causes neuro-fibromatosis type 2.

              Neurofibromatosis type 2 (NF2) is a monogenic dominantly inherited disease predisposing carriers to develop nervous system tumours. To identify the genetic defect, the region between two flanking polymorphic markers on chromosome 22 was cloned and several genes identified. One is the site of germ-line mutations in NF2 patients and of somatic mutations in NF2-related tumours. Its deduced product has homology with proteins at the plasma membrane and cytoskeleton interface, a previously unknown site of action of tumour suppressor genes in humans.
