An analysis of the topic of the neurofibromatosis

In most studies a general health questionnaire the short form 36 health survey: SF and a questionnaire more specific to QoL Skindex are used to measure QoL [ 1415 ].

Neurofibromatosis type 1

The meta-analysis was limited to studies published in English. The studies obtained through the search strategy and other references were entered with the reference management software Endnote , and duplicate items were deleted using the features of this software. A rare form of NF is schwannomatosis. With the exception of the existence of deep intronic mutations in SPRED1 and NF1, some of these mutation-negative patients most likely harbor a segmental or mosaic variant of the NF1 and the affected tissue must be therefore analyzed to identify the mutation. For 15 percent of individuals with NF1, the symptoms can be severely debilitating. NF1 mutations were identified in 97 individuals, among which 34 intragenic mutations have not previously been reported. Thus, we will be able to establish optimized strategies for early diagnosis and provide genetic counseling in the Chinese population.

It causes pain primarily, and in any part of the body. NF1 mutations were identified in 97 individuals, among which 34 intragenic mutations have not previously been reported. A third study used data from Japanese vital statistics for — on deaths in which neurofibromatosis was listed as the underlying cause of death.

Nevertheless, exon 15 is prone to be a mutation hotspot and shows potential for further research in Chinese populations Figure S1. How is neurofibromatosis diagnosed? Mutation analysis is 95 percent accurate in finding a mutation for NF1, and 65 percent accurate for NF2.

Disease that causes tumors all over body

Neurofibromatosis is diagnosed from a combination of findings. In most studies a general health questionnaire the short form 36 health survey: SF and a questionnaire more specific to QoL Skindex are used to measure QoL [ 14 , 15 ]. Mutation analysis is 95 percent accurate in finding a mutation for NF1, and 65 percent accurate for NF2. Other manifestations including pigmentary abnormalities, low-grade gliosis, skeletal dysplasia, and the involvement of numerous other organ systems are seen in NF1 patients [ 3 , 4 , 5 , 6 ]. The mean age at death in this study was 43 years Imaizumi All participants gave their written informed consent. Family and NF patients had lower quality of life in all aspects of QoL than controls.

Tumors, or neurofibromas, grow along the body's nerves or on or underneath the skin.
