Question: Which is the gene mutated in type 1 neurofibromatosis?

Context:
Individuals with NF1 harbor 1 mutated NF1 allele
type 1 (NF1) is a hereditary disorder caused by mutations in the NF1 gene
The NF1 gene, mutated in NF1, is also commonly mutated in sporadic glioblastoma multiforme (GBM)
 type 1 (NF1) is a common genetic disease caused by haploinsufficiency of the NF1 tumor-suppressor gene
Neurofibromatosis type 1 (NF1) is a common disorder of dysregulated tissue growth secondary to mutations in the tumor suppressor gene NF1
tumor suppressor protein neurofibromin, which is mutated in NF1
 Neurofibromatosis type 1 is one of the most common autosomal dominant disorders, affecting about 1:3,500 individuals. NF1 exon 7 displays weakly defined exon-intron boundaries
Loss of heterozygosity (LOH) of NF1
Neurofibromatosis type 1 (NF1) is a neurocutaneous disorder resulting in the growth of a variety of tumours, 
ten occur in both children and adults as sporadic events with no family history of the disease, but they are also among the clinical manifestations of a significant number of familial cancer syndromes, including familial retinoblastoma, neurofibromatosis 1 and 2, tuberous sclerosis, and Cowden, Turcot, Li-Fraumeni and nevoid basal cell carcinoma (Gorlin) syndromes. 
These genes include RB1, NF1, NF2, TSC1, TSC2, TP53, PTEN, APC, hMLH1, hPSM2, and PTCH
von Recklinghausen syndrome (NF-1) (OMIM 162200) carrying NF1 germline mutations
mutations of the NF1 gene have been reported in patients with neurofibromatosis type 1 (NF1)
NF1 gene mutation in a Japanese patient with neurofibromatosis type 1 
Neurofibromatosis 1 gene (NF1 ) fulfills the criteria of a tumor suppressor gene and is deleted or mutated heterozygously in patients with NF1
type 1 (NF1) is one of the most common human genetic disorders and is associated with significant morbidity and mortality. The gene responsible for this disorder, NF1, encodes neurofibromin,
 genes mutated in these two disorders encode tumor suppressor proteins, termed neurofibromin (NF1)
 tumour-suppressor genes, Nf1 and Trp53. Humans with mutations in NF1 develop neurofibromatosis type I (NF1
type 1 (NF1) is an autosomal dominant genetic disorder affecting one in 3,500 individuals. The mutation rate in the NF1 gene is one of the highest known for human genes.
patients with neurofibromatosis type 1 (NF1) were screened for mutations in the NF1 gene.
It is caused by a wide spectrum of mutations affecting the NF1 gene. 
NF1) is a common familial tumour syndrome with multiple clinical features such as neurofibromas
This neoplastic lesion is a common feature of neurofibromatosis type 1 (NF1), one of the most common autosomal dominant disorders. The NF1 gene codes for a protein called "neurofibromin.
type 1 (NF1) and type 2 (NF2) are connected with genes localized on chromosomes 17 and 22, respectively. The genes that are inactivated in neurofibromatosis code for the proteins neurofibromine and merline
neurofibromatosis type 1 (NF1) gene, well recognized for its high frequency of spontaneous mutations.
An NF1 gene was identified as a gene whose loss of function causes an onset of human disorder, neurofibromatosis type I.
type 1 (NF1) is caused by deletions, insertions, translocations, and point mutations in the NF1 gene
type 1 (NF1) gene is a tumor suppressor gene, and the NF1 gene product, neurofibromin
ysine 1423 of neurofibromin (neurofibromatosis type I gene product [NF1]) plays a crucial role in the function of NF1.

Answer: NF1 gene, encoding neurofibromin 1
Exact answer: NF1
