Presentation
We present a comprehensive clinical and molecular analysis of eight affected individuals from three unrelated families displaying features of NF1 and NFNS. [ncbi.nlm.nih.gov]
Rarely, a mutation in PTPN11 in addition to an NF1 mutation is present. We present the clinical and molecular characterization of a family displaying features of both NS and NF1, with complete absence of neurofibromas. [diva-portal.org]

Her dermatological examination revealed bilateral axillary freckling, several hyperpigmented macules and patches between 1 and 5 cm in diameter which were consistent with café-au-lait spots. [medicaljournals.se]
The patient’s father also had features representing both NF1 and NS such as multiple café-au-lait spots, short stature, relative macrocephaly, and axillary freckling, suggesting NF syndrome, and findings such as prominent nasolabial folds, low-set ears [jcrpe.org]

Workup
[…] be called Noonan syndrome, pigmented villonodular synovitis, central giant cell granuloma, or cherubism, because each of these is a specific diagnostic entity sui generis and the use of such terms results in nosologic blinders that tend to limit the workup [genome.jp]
Treatment
The case is the first NFNS patient reported in the literature who was diagnosed to have GHD and who received GH treatment until reaching final height. [ncbi.nlm.nih.gov]

Prognosis
Diagnosis - Neurofibromatosis-Noonan syndrome These home medical tests may be relevant to Neurofibromatosis-Noonan syndrome: * Colon & Rectal Cancer: Home Testing o Home Colorectal Cancer Tests o Home Fecal Occult Bleeding Tests Prognosis - Neurofibromatosis-Noonan [checkorphan.org]
Conclusively, these studies contribute to further understanding of the RAS-MAPK syndromes and facilitate the diagnostic process and future prognosis prediction. [diva-portal.org]
Prognosis Prognosis for Noonan syndrome is largely dependent on the extent of the various medical problems, particularly the heart defects. [encyclopedia.com]
Etiology
In light of a studied Greek family, a new theory for etiological pathogenesis of NFNS is suggested. [ncbi.nlm.nih.gov]
To investigate the etiology of the phenotype, mutational analysis of NF1 was conducted, revealing a novel missense mutation in exon 24, p.L1390F, affecting the GAP-domain. [diva-portal.org]

Epidemiology It is inherited in an autosomal dominant manner. [patient.info]
Age-appropriate guidelines for the management of Noonan syndrome are available. 1 Epidemiology Noonan syndrome is characterized by marked variable expressivity, which makes it difficult to identify mildly affected individuals. [aafp.org]
Epidemiology LS is a rare condition, but the exact birth prevalence is unknown. Not less than 200 patients have been reported and two reviews published [ 1, 4 ]. [ojrd.biomedcentral.com]
Pathophysiology
The final chapter covers the critical area of treatment including prospects emerging from an improved understanding of the pathophysiology of these disorders. [books.google.com]
Such observations raise the intriguing question of whether shared pathophysiological mechanisms may underlie the neuropsychological concerns that are described in NS and NF1. [jneurodevdisorders.biomedcentral.com]
Prevention

This may prevent apoptosis of CD4 T cells, which is important in the development of autoimmunity (9). Our case had two coexisting autoimmune diseases – vitiligo and Hashimoto’s disease. [medicaljournals.se]
By blocking HMG-CoA reductase, the drug prevents overactivation of the Ras protein, which leads to deficits in long term potentiation, a mechanism of learning and memory. [techtransfer.universityofcalifornia.edu]
Sometimes it may leave scars, which may prevent hair growth in those areas. café-au-lait spots can occur, not unlike those seen in neurofibromatosis. [encyclopedia.com]
Early monitoring of hearing quality is important for young NS-patients in order to prevent speech abnormalities. Chest/back abnormalities are common in NS-patients in a form of pectus carinatum and/or excavatum and scoliosis. [centogene.com]
