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]

Case Report A 13-year-old girl presented with short stature. [jcrpe.org]
Abstract We are reporting on a boy and his mother with neurofibromatosis and manifestations of Noonan syndrome, including short stature, ptosis, midface hypoplasia, and short neck. [ncbi.nlm.nih.gov]
- Poor Growth
Patients with NFNS who show poor growth should be evaluated for GHD. [ncbi.nlm.nih.gov]
Newborn infants with NS usually have feeding problems resulting in poor growth and delayed bone growth. Finally, more than 50% of all affected females and 40% of affected males have an adult height that is below the third centile 3. [centogene.com]

- Cafe-Au-Lait Spots
Watson syndrome (WTSN) [MIM:193520]: A syndrome characterized by the presence of pulmonary stenosis, cafe-au-lait spots, and mental retardation. It is considered as an atypical form of neurofibromatosis. [genecards.org]
NF1 is characterized by neurofibromas, cafe-au-lait spots, osseous lesions, and brain tumors such as gliomas. NS presents characteristic facial appearance, short stature, hypertelorism, strabismus, and low-set ears. [genome.jp]
The child had right hemiparesis, pectus carinatum, right-sided cryptorchidism with poorly developed scrotum, and multiple pigmented macules along with multiple cafe-au-lait spots. [jpgmonline.com]

[…] clinical features is: cafe-au-lait macules, axillary freckling, Lisch nodules and neurofibromas. [familialcancerdatabase.nl]
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]

CASE REPORT A 20-year-old female patient was admitted to the hospital with hyperpigmented skin patches that had been present since birth and tumoral formations on her skin that had recently increased in number. [medicaljournals.se]

- Short Neck
He has multiple café-au-lait spots and axillary freckling, relative macrocephaly, ptosis, mid-face hypoplasia, short neck and pulmonic stenosis. [ncbi.nlm.nih.gov]
With 5 months, there was a global development disorder, brachycephaly, broad forehead with prominent metopic suture, infraorbital folds, pointed chin, low-set ears, short neck, excess skin on the neck and > 6 café-au-lait spots with a diameter > 0.5 cm [thieme-connect.com]

Other features shared between the two conditions include short stature, intellectual disability, lax joints, and head/neck features such as a highly arched palate, a short neck, a large forehead, and low-set ears. [forgottendiseases.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]
[…] and the fifth years of treatment (15). [jcrpe.org]
Applications • Treatment of cognitive dysfunction associated with NF1 • Treatment of cognitive dysfunction associated with Noonan syndrome • Treatment of other disorders driven by hyperactivation of the Ras-MAPK pathway Advantages • Statins would represent [techtransfer.universityofcalifornia.edu]
Treatment to manage mild blood-clotting problems may be necessary. Dental and orthodontic treatment may be advised. Glue ear can be managed with an operation to insert drainage tubes (grommets). [betterhealth.vic.gov.au]

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]
Prognosis Prognosis for Noonan syndrome is largely dependent on the extent of the various medical problems, particularly the heart defects. [encyclopedia.com]
Conclusively, these studies contribute to further understanding of the RAS-MAPK syndromes and facilitate the diagnostic process and future prognosis prediction. [diva-portal.org]
Etiology
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. [ncbi.nlm.nih.gov]
Epidemiology

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
Prevention - Neurofibromatosis-Noonan syndrome Not supplied. [checkorphan.org]
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]
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]
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]
