Distribution of 13 truncating mutations in the neurofibromatosis 1 gene

Human Molecular Genetics, 1995
Neurofibromatosis 1 (NF1) is a common genetic disorder characterized by abnormalities of tissues derived from the neural crest. To define germ-line mutations in the NF1 gene, we studied 20 patients with familial or sporadic cases of NF1 diagnosed clinically and one patient with only café-au-lait spots and no other diagnostic criteria.

Somatic mutations in the neurofibromatosis 1 gene in human tumors

Cell, 1992
The neurofibromatosis 1 (NF1) gene product, neurofibromin, contains a GTPase-activating protein (GAP)-related domain, or NF1 GRD, that is able to down-regulate p21ras by stimulating its intrinsic GTPase. Since p21ras.GTP is a major regulator of growth and differentiation, mutant neurofibromins resulting from somatic mutations in the NF1 gene might ...

Spinal neurofibromatosis in a family with classical neurofibromatosis type 1 and a novel NF1 gene mutation

Journal of Clinical Neuroscience, 2014
Familial spinal neurofibromatosis (FSNF) is a rare form of neurofibromatosis type 1 (NF1) characterized by multiple, histologically proven neurofibromas of the spinal roots leaving no intact segments and associated neurofibromas of major peripheral nerves. It is sometimes associated with other NF1 stigmata. Most patients have NF1 gene mutations.

Analysis of an alternatively spliced exon of the neurofibromatosis type 1 gene in cultured melanocytes from patients with neurofibromatosis 1

Archives of Dermatological Research, 1995
Neurofibromatosis type 1 (NF1) is characterized by clinical features that primarily affect tissues derived from the neural crest (neurofibromas, café-aulait macules). Because aberrant regulation of alternative splicing in the NF1 gene transcript may be of functional significance, cultured melanocytes from café-aulait macules (CALM), as an example of ...

Genomic characterization of the Neurofibromatosis Type 1 gene of Fugu rubripes

Gene, 1998
The genomic structure of the Neurofibromatosis Type1 (NF1) gene of Fugu rubripes was investigated by sequence analysis of two overlapping cosmids. The Fugu NF1 gene spans 27 kb and is 13 times smaller than the human counterpart owing primarily to reduced intron size.

Expression of the neurofibromatosis 1 (NF1) gene during growth arrest

NeuroReport, 1996
The neurofibromatosis 1 (NF1) gene product, neurofibromin, is a tumor suppressor gene product capable of inhibiting the growth of cells in culture. If neurofibromin suppresses cell growth by arresting cells in G0 or G1, its expression might be regulated in a cell cycle-dependent fashion. In this study, we demonstrate that RAT-1A fibroblasts arrested in

Transcriptional Regulation of the Neurofibromatosis Type 1 Gene

2003
Abstract : The goal of this project was to understand the transcriptional regulation of the NFl gene. Specifically to further characterize TLF-mediated regulation and identify new factors that participate in the control of NFl regulation. In addition, an attempt was made to determine signaling pathways that affect NFl levels.

A deletion in the 5 ′-region of the neurofibromatosis type 1 (NF1) gene

Human Genetics, 1994
A new mutation, the first one close to the 5'-end of the neurofibromatosis type 1 (NF1) gene, was found when RNA preparations from various cell types of 15 NF1 patients were analysed by reverse transcription and subsequent multiplex polymerase chain reaction. This mutation removes the 84 bp of exon 3 precisely from the cDNA.

Studies of Neurofibromatosis-1 Modifier Genes

2004
Abstract : This project aims to collect NF1 patient DNAs required to identify neurofibroma burden modifier genes, to perform an allele association study for three classes of potential modifiers, and to evaluate more global approaches. Over four years we aim to collect 1200 DNAs from adult NF1 patients that represent the top and bottom 20% of dermal ...

Mutational and functional analysis of the neurofibromatosis type 1 ( NF1 ) gene

Human Genetics, 1996
Neurofibromatosis type 1 (NF1) is one of the most common autosomal dominant disorders. It is caused by mutations in the NF1 gene which comprises 60 exons and is located on chromosome 17q. The NF1 gene product, neurofibromin, displays partial homology to GTPase-activating protein (GAP).
