I developed cafe au lait like spots when I was a teenager, they appeared all over my neck, back, and some on my chest. For a while they were severe, but then they went away most of them on my chest/neck (apparently back) I still have some. They do not itch or anything. Occasionally they come back, and have been creeping up higher on my neck. I read that the appearance of cafe au lait spots when there are more than a certain number and are bigger than 5mm is usually a sign of something being quite wrong like Neurofibramotosis? Does anyone know about these spots? Are they pretty clearly indicative of a problem if there a lot of large ones? I have some other probs I mentioned in another post you can refer too but I dont have deformities, which seems to occur in a lot of conditions related to these spots at least not outward deformity my organs are a bit off as I said. Could these spots be nothing? Maybe the key to getting a diagnosis?I went to the doctor and showed her just because I was there ...

Neurofibromatosis type 1 (NF1) is a genetic disorder characterized by a predisposition to develop multiple benign tumors. A major feature of NF1 is the development of localized cutaneous neurofibromas. Cutaneous neurofibromas manifest in | 99% of adults with NF1 and are responsible for major negative effects on quality of life. Previous reports have correlated increased burden of cutaneous neurofibromas with age and pregnancy, but longitudinal data are not available to establish a quantitative natural history of these lesions. The purpose of this study is to conduct a prospective natural history study of 22 adults with NF1 over an 8-year period to quantify cutaneous neurofibroma number and size. The average monthly increase in volume for cutaneous neurofibromas was 0.37 mm3 in the back region (95% CI (0.23, 0.51), p | 0.0001), 0.28 mm3 in the abdominal region (95% CI (0.16, 0.41), p | 0.0001), and 0.21 mm3 in the arm/leg region (95% CI (0.08, 0.34), p = 0.0022).

Neurofibromatosis 1(NF1) is a rare autosomal dominant disorder with an incidence of one birth out of 3000. NF1 gene is located in 17q11.2. The penetrance is near 100% by the age of 8 and the de novo mutations represent half the cases. The product of NF1 gene is neurofibromin, a protein controlling cellular differentiation and proliferation. Phenotypic expression is variable even in the same family. Neurofibromatosis 1 is characterized by café au lait spots, freckling of the folds, Lischnodules (hamartomas of iris) and multiple neurofibromas. Manifestations of neurofibromatosis 1 are pleiotropic, potentially severe and unpredictable. Morbidity and mortality associated to neurofibromatosis 1 are linked with complications, optic pathway gliomas, neurofibromas of the spine or of peripheral nerves, learning disabilities, scoliosis and bone abnormalities and vasculopathy. The investigators already demonstrated the existence of modifiers, genes modifying the phenotypic expression of neurofibromatosis ...
In infants and children, neurofibromatosis type I can interfere with the development of the spine. The disease can affect the protective covering of the spine, called the dura. Increased pressure in the spinal fluid due to neurofibromas of the spinal nerves can result in dural ectasia, which is a ballooning out of a sac that contains the cerebrospinal fluid. This condition may result in pain in the back and limbs, bladder control problems, and numbness in severe cases. Neurofibromatosis may cause tumors on an around the spinal cord. Even benign tumors in this area can cause pain and weakness in the most severe cases.. Scoliosis, an irregular side curvature of the spine from left to right, and kyphosis, or a rounded or forward angulated back, occur together or separately in about one in five people with neurofibromatosis type I. Osteoporosis is common among neurofibromatosis type I sufferers, who generally have lower bone density by age than healthy individuals. While physical therapy may be able ...
BACKGROUND:. Neurofibromatosis Type 1 (NF1) is an autosomal dominant, progressive genetic disorder characterized by diverse clinical manifestations. Patients with NF1 have an increased risk of developing tumors of the central and peripheral nervous system including plexiform neurofibromas (PN), dermal neurofibromas, optic pathway tumors, brain tumors, malignant peripheral nerve sheath tumors (MPNST), juvenile myelomonocytic leukemia, and pheochromocytomas. In addition, NF1 manifests in essentially every organ system, with for example, skeletal and vascular abnormalities, and cognitive deficits. Thus, the care for individuals with NF1 requires a multidisciplinary approach. The natural history of NF1 related tumor and other manifestations is poorly understood, and for most NF1 related tumor manifestations the only standard treatment option is surgery. The NIH Clinical Center provides the ideal infrastructure for evaluation of the natural history of rare diseases. A better understanding of the ...
Ahmet Mesrur Halefo lu, Zehra Berna Ar k. Neurofibromatosis is classified into two different inherited disorders that are known as type 1 and type 2 forms. Type I consists of the peripheric form and is also known as von Recklinghausen disease. It is far more common than type 2 disease and is characterised by benign peripheral nerve sheath tumors and cafe an lait spots on the skin. Other than neurofibromas or schwannomas, neurofibromatosis type I patients have a predilection for developing central nervous system abnormalities which include such as optic nerve gliomas and dysplastic as well as hamartomatous lesions. In our case, we demonstrated a 29 year old female patient with known history of neurofibromatosis type I. Patient had multiple neurofibromas in the pelvis, at the sacral nerve roots and scattered throughout the subcutaneous region. Magnetic resonance imaging revealed characteristic signal intensity features of these lesions and provided useful information about the relationship of ...
Neurofibromatosis is a genetic disorder that causes tumors in the nervous system. Tumors develop in the nerves or the tissue that surrounds the nerves, called the myelin sheath. Neurofibromatosis is divided into 3 types, neurofibromatosis type 1 (NF1), neurofibromatosis type 2 (NF2), and schwannomatosis. The type is determined by the specific genes that are affected. This articles discusses NF1, the most common neurofibromatosis. It affects the nerves outside the brain and spinal cord, called peripheral nerves.
A 9-year-old girl presents with multiple hyperpigmented lesions, some of which have been present since birth (Figure 1). The lesions have increased in size and number. There is no history of seizures. Her 40-year-old mother has multiple skin nodules (Figure 2).
Neurofibromatosis type 1 (NF1) is an autosomal dominant disorder that affects multiple organ systems.1 It can be diagnosed if a patient presents with two or more of the following features: six or more café-au-lait macules of larger than 5mm in diameter before puberty or larger than 1.5mm in diameter after puberty, axillary or inguinal skinfold freckling, two or more dermal neurofibromas or one plexiform neurofibroma, two ore more iris hamartomas, an optic pathway glioma, a distinctive long bone dysplasia involving the sphenoid wing or thinning of the long bone cortex with or without pseudarthrosis, and a first-degree relative with NF1.2 Neurofibromas, one of the main clinical features, usually present as discrete nodules or pedunculated masses, but cannot be presented as vasculitic skin purpura.3 Here, we report a female patient with NF1 who demonstrated vasculitic skin rash..

PY - 2016/5/11. Y1 - 2016/5/11. N2 - Neurofibromatosis type 1 (Nf1) is a progressive, autosomal disorder with a large degree of variability and severity of manifestations including neurological, cutaneous, ocular/orbital, orthopedic, and vascular abnormalities. Nearly half of Nf1 patients presents with cognitive impairment, specifically spatial learning deficits. These clinical manifestations suggest a global impairment of both central and peripheral nervous system functions in neurofibromatosis. Nf1 encodes for neurofibromin, a Ras GTPase-activating protein (Ras GAP) that has been implicated in the regulation of long-term potentiation (LTP), Ras/ERK (extracellular signal-regulated kinase) signaling, and learning in mice. Over the last decades, mice with a targeted mutation in the Nf1 gene, Nf1−/− ...

Introduction: Neurofibromatosis type 1 (NF1, also known as von Recklinghausens disease) is a genetic disorder with an autosomal dominant pattern of inheritance affecting the skin, skeletal, and neural tissues. A defect in the NF1 gene results in a hyperactive Ras pathway, which can in turn activate a variety of signaling pathways in a broad range of cells and tissue types. The purpose of the study was to examine cephalometric radiographs to assess craniofacial morphology of NF1 patients. Methods: A total of 74 Caucasian adult patients with NF1, and their age and gender matched controls, were selected for the study. Cephalometric radiographs were obtained for all subjects and traced in the Dolphin Software. Sixteen (16) cephalometric (linear and angular) measurements reflecting the dimensions of the cranial base, maxilla, mandible, and vertical facial heights were collected and analyzed. Results: The results showed that patients with NF1 had shorter mandible, shorter maxilla, shorter cranial ...

Melanocytic iris hamartomas, sometimes called Lisch nodules, are considered pathognomonic of this disease but are found in only about 75% of patients. These appear as sharply defined, smooth masses on the stromal surface and consist of spindle cells of melanocytic origin. Their presence correlates with the severity of skin freckles and cafe-au-lait spots. Also characteristic of neurofibromatosis 1 are eyelid fibromas causing ptosis and the familiar horizontal S-sign in the upper lid margin but these are only found in one-third of patients. Ciliary body cysts have been reported to occur at a frequency of 78%, or 10 times more frequently than in unaffected individuals. Nearly half of patients have occludable anterior chamber angles (Types 1 and 2).. Gliomas of the optic nerves, chiasm or optic tracts are slow growing astrocytomas that occur in about 15% of children at a mean age of about 5 years. While these comprise the most common intracranial tumors in NF1, they typically have a benign course ...
Neurofibromatosis (NF) is a group of three conditions in which tumors grow in the nervous system. The three types are neurofibromatosis type 1 (NF1), neurofibromatosis type 2 (NF2), and schwannomatosis. In NF1 symptoms include light brown spots on the skin, freckles in the armpit and groin, small bumps within nerves, and scoliosis. In NF2 there may be hearing loss, cataracts at a young age, balance problems, flesh colored skin flaps, and muscle wasting. The tumors are generally non cancerous. The cause is a genetic mutation in certain genes. In half of cases these are inherited from a persons parents while in the rest, they occur during early development. The tumors involve supporting cells in the nervous system rather than the neurons. In NF1 the tumors are neurofibromas (tumors of the peripheral nerves), while in NF2 and schwannomatosis tumors of Schwann cells are more common. Diagnosis is typically based on the signs and symptoms and occasionally supported by genetic testing. There is no ...
Results Novel clinical features found to be associated with type-1 NF1 deletions included pes cavus (17% of patients), bone cysts (50%), attention deficit (73%), muscular hypotonia (45%) and speech difficulties (48%). Type-1 NF1 deletions were found to be disproportionately associated with facial dysmorphic features (90% of patients), tall stature (46%), large hands and feet (46%), scoliosis (43%), joint hyperflexibility (72%), delayed cognitive development and/or learning disabilities (93%) and mental retardation (IQ,70; 38%), as compared with the general NF1 patient population. Significantly increased frequencies (relative to the general NF1 population) of plexiform neurofibromas (76%), subcutaneous neurofibromas (76%), spinal neurofibromas (64%) and MPNSTs (21%) were also noted in the type-1 deletion patients. Further, 50% of the adult patients exhibited a very high burden of cutaneous neurofibromas (N≥1000). ...

Researchers studying neurofibromatosis type 1 - a rare disease in which tumors grow within nerves - have found that the tumors are triggered by crosstalk between cells in the nerves and cells in the blood. The researchers, who were funded by the National Institutes of Health (NIH) and the Department of Defense (DOD), also found that a drug on the market for treating certain kinds of blood cancer curbs tumor growth in a mouse model of neurofibromatosis type 1. A clinical trial of the drug is underway in people with the disease.

Many thanks for your support -- and dont forget to forward this to anyone who you think might want to donate too!. We will be walking in Memphis as a family!. Savannahs Story:. Savannah was diagnosed with NF1 shortly after birth. Her mom, Dana, had NF1 so the cafe au lait spots were enough for a diagnosis. Savannah is now 7 years old and a second grader at Knoxville Christian School in Knoxville, TN. She is very bright, but does struggle at times due to Attention Deficit Hyperactivity Disorder. In April of 2011, Savannah had a routine MRI. The MRI revealed a lump on her brainstem and cervical spine. She went to St Jude for an evaluation. At this time they are not 100% sure what the mass is or what it will mean for Savannahs future. She is to return to St Jude every three months for repeat MRIs to monitor the brain mass. Savannah rarely lets her condition get her down. She is a happy girl whose motto is Everyone needs a hug, so I am going to hug everybody!. Carolines Story:. Caroline was ...

A set of neurofibromatosis type 1 (NF1) patients was screened for large NF1 gene deletions by comparing patient and parent genotypes at 10 intragenic polymorphic loci. Of 67 patient/parent sets (47 new mutation patients and 20 familial cases), five (7.5%) showed loss of heterozygosity (LOH), indicative of NF1 gene deletion. These five patients did not have severe NF1 manifestations, mental retardation, or dysmorphic features, in contrast to previous reports of large NF1 deletions. All five deletions were de novo and occurred on the maternal chromosome. However, two patients showed partial LOH, consistent with somatic mosaicism for the deletion, suggesting that mosaicism may be more frequent in NF1 than previously recognised (and may have bearing on clinical severity). We suggest that large NF1 deletions (1) are not always associated with unusual clinical features, (2) tend to occur more frequently on maternal alleles, and (3) are an important mechanism for constitutional and somatic mutations in ...
Eighty-one subjects (56 affected patients and 25 parents of isolated affected cases) from 63 families with neurofibromatosis type 1 (NF1) on the North Western Regional Genetic Family Register (NWRGFR) were interviewed. Patients were interviewed either before (n = 26) or after (n = 55) genetic counselling. In the group as a whole, knowledge of the clinical features and the genetic aspects of the condition was poor (mean score 7 within the range of 0 to 18). The following factors were significantly associated with higher knowledge: (1) genetic counselling, (2) higher social class, (3) child with NF1, (4) when NF1 had influenced reproductive decisions, (5) young age at diagnosis, and (6) member of a patient support group. The majority of the affected subjects perceived themselves to be more severely affected than by medical classification, with persons who had been diagnosed later in life, had a child with NF1, or who were concerned about the cosmetic aspects of the disease perceiving themselves to ...
Neurofibromatosis type 2 (NF2) is a rare genetic disorder that affects around 1 in 25,000 individuals. In about half of these people, the condition is inherited, while the other half develop a spontaneous mutation and there is no family history of the condition. The mutation that causes NF2 occurs on a single gene located on chromosome 22. A person with NF2 has a 50% chance of passing the illness onto their offspring.

Neurofibromatosis type 2 (NF2) is a hereditary condition that makes a person susceptible to developing schwannomas, benign tumors that form on the connective tissue surrounding nerves.
Neurofibromatosis type I (NF1) is one of the most common single-gene disorders that causes learning deficits in humans. Mice carrying a heterozygous null mutation of the Nfl gene (Nfl(+/-) show important features of the learning deficits associated with NF1 (ref. 2). Although neurofibromin has several known properties and functions, including Ras GTPase-activating protein activity, adenylyl cyclase modulation and microtubule binding, it is unclear which of these are essential for learning in mice and humans. Here we show that the learning deficits of Nf1(+/-) mice can be rescued by genetic and pharmacological manipulations that decrease Ras function. We also show that the Nf1(+/-) mice have increased GABA (gamma-amino butyric acid)-mediated inhibition and specific deficits in long-term potentiation, both of which can be reversed by decreasing Ras function. Our results indicate that the learning deficits associated with NF1 may be caused by excessive Ras activity, which leads to impairments in ...

The appearance of neurofibromas in adolescence and in pregnancy suggests that hormones influence the development of these tumours. The basis for any possible hormonal influence is unknown. Some investigators have studied the presence of oestrogen receptors in neurofibromas. Martuza and colleagues only detected these receptors in one of six neurofibromas. Chaudhuri and colleagues could not detect steroid hormone receptors (receptors for oestrogen, progesterone, androgen, and glucocorticoid) in five neurofibromas. These studies suggest that the alterations seen in the neurofibromas of patients with NF1 during puberty and pregnancy are not related to steroids ...
