The authors concluded that adults with NF1 have a higher likelihood of having various gastrointestinal problems and the study in adults compliments an earlier study that found similar results in children with NF-1.
Is neurofibromatosis type 1 (NF1) serious?
The symptoms of neurofibromatosis type 1 (NF1) are often mild and cause no serious health problems. But some people will have severe symptoms. The symptoms of NF1 can affect many different areas of the body, but it's unlikely someone will develop all of them.
Are digestive issues common in NF?
Yes digestive issue are common in NF. People with NF have five times the number of mast cells as normal folk. The mast cells are in your gut and can become inflamed and be painful. The mast cells release histamine as part of this process. So the goal of treatment is to avoid inflammation.
How does NF1 affect the body?
NF1 can cause curvature of the spine (scoliosis) that may need bracing or surgery. NF1 is also associated with decreased bone mineral density, which increases the risk of weak bones (osteoporosis). Vision problems. Sometimes a tumor develops on the optic nerve (optic glioma), which can affect vision.
What does NF1 stand for?
Neurofibromatosis type 1 (NF1), historically called von Recklinghausen disease Most tumors are non-cancerous (benign), although some may become cancerous (malignant).
Can NF1 cause bowel problems?
Gastrointestinal tract lesions are not uncommon in NF1 [6] and are reported in 10 to 25% of all cases [12, 14].
What problems can neurofibromatosis cause?
The tumors in these disorders are usually noncancerous (benign), but sometimes can become cancerous (malignant). Symptoms are often mild. However, complications of neurofibromatosis can include hearing loss, learning impairment, heart and blood vessel (cardiovascular) problems, loss of vision, and severe pain.
What body systems are affected by neurofibromatosis?
Neurofibromatosis (NF) is a genetic neurological disorder that can affect the brain, spinal cord, nerves and skin. Tumors, or neurofibromas, grow along the body's nerves or on or underneath the skin.
How does neurofibromatosis affect you physically?
Neurofibromatosis is a genetic disorder that is typically diagnosed in childhood or early adulthood. This disorder can cause tumors to develop in the nervous system, including the brain, spinal cord and nerves. In most cases, these tumors are benign and slow-growing.
Does NF1 get worse with age?
Typically, adults with NF1 will develop more neurofibromas over time. They may grow for a period of time and then stop growing. In addition, they may change in shape or color as they grow. Sometimes, they can also be associated with itching or slight discomfort when bumped.
Is NF1 considered a disability?
Although neurofibromatosis is a serious condition, the Social Security Administration (SSA) does not specifically list the disorder as a disability. But, the symptoms that accompany the condition can be reviewed for benefits.

NF1 can lead to problems within various systems, organs and functions of the body including: Skin, bone and eye abnormalities. Nerve tumors. Optic nerve and other brain tumors.
Does NF1 make tired?
Conclusion: This study suggests that children with NF1 are affected by perceived fatigue when compared with healthy children who do not have NF1.
Does NF1 weaken immune system?
Although it has not been thoroughly studied in NF1, the high concentrations of cytokines found in the serum of NF1 patients may alter immune function in favor of immune suppression and tumorigenesis.
Does NF1 affect teeth?
In particular, complex retentions of teeth have to be expected in NF1 (25). Two oral health studies on NF1 patients have already been performed in other countries. A study from Canada (27) revealed significantly higher rates of decayed teeth in patients with NF1 than in a reference group of healthy individuals.
What is the life expectancy of someone with NF1?
Mean and median ages at death for persons with NF1 were 54.4 and 59 years, respectively, compared with 70.1 and 74 years in the general population.
Is there a cure coming soon for neurofibromatosis?
Neurofibromatosis can be treated and managed, but there is no cure. MSK recently launched a neurofibromatosis center to improve the treatment of this disease. Neurofibromatosis is a genetic disorder that often leads to tumors throughout the nervous system, including the brain, spinal cord, and nerves.
What is the life expectancy of a person with neurofibromatosis?
Mean and median ages at death for persons with NF1 were 54.4 and 59 years, respectively, compared with 70.1 and 74 years in the general population.
Does neurofibromatosis weaken your immune system?
Mutation of NF1 causes changes in cytokine levels, mast cells, macrophages, microglia, T cells and B cells, suggesting that immune system activities are altered.
Does neurofibromatosis cause dementia?
The hazard ratio for dementia in NF1 was 1.67 (95% confidence interval [CI] 1.00–2.80, P = 0.050). In an analysis stratified by the type of dementia, the risk for Alzheimer disease was increased in NF1 compared to controls with a hazard ratio of 2.88 (95% CI 1.47–5.66, P = 0.002).
At what age is neurofibromatosis usually diagnosed?
They can be present at birth or may not become noticeable for many years. Although some cutaneous neurofibromas arise in childhood, most start appearing during or after the teenage years. Freckling usually appears by 3 to 5 years of age. Freckles are similar in appearance to café-au-lait spots but are smaller in size.
How does NF1 work?
Most people without Neurofibromatosis type 1, carry two working copies of the NF1 gene in their cells. One copy of NF1 is inherited from the mother and one from the father.
How do you get NF1?
About half of children with Neurofibromatosis type 1, inherit the NF1 gene mutation from a parent who also has the syndrome. The other half of children with Neurofibromatosis type 1, have a new NF1 mutation that did not come from a parent. These children have no history of the syndrome in their family. In these cases, the change either happened in an egg or sperm cell when the child was formed or in one of the child’s cells during pregnancy. These children are the first in their families to have Neurofibromatosis type 1. No matter how they acquired the NF1 mutation, people with Neurofibromatosis type 1, have a 50% or 1 in 2 chance of passing it on to their children.
What is Neurofibromatosis type 1?
Neurofibromatosis type 1 is a genetic condition that can affect many areas of the body, including the skin, eyes, bones, blood vessels, nerves and central nervous system . People with Neurofibromatosis type 1 also have a higher risk of developing certain kinds of cancerous and non-cancerous tumors, including:
How is Neurofibromatosis type 1 diagnosed?
A diagnosis of Neurofibromatosis type 1 can be made with or without genetic testing. Genetic testing can be offered to people who have features that suggest Neurofibromatosis, type 1; however, it is possible to establish a clinical diagnosis without genetic testing. A person with two or more of the following features can be given a clinical diagnosis of Neurofibromatosis type 1 even if genetic testing is not done, or if it is performed and the result comes back negative:
What is the cancer risk for people with Neurofibromatosis type 1?
Nearly all people with Neurofibromatosis type 1 develop non-cancerous neurofibromas . They usually start to appear in late childhood and adolescence, although they can continue to develop throughout life. Many women with Neurofibromatosis type 1 experience a rapid increase in the number and size of neurofibromas during pregnancy.
How are people with Neurofibromatosis type 1 screened for tumors?
People with Neurofibromatosis type 1, should be managed by a health care provider who is familiar this condition. There are clinics throughout the country that specialize in taking care of people with Neurofibromatosis type 1. For more information, please see the “Resources” section below. Although most of the tumors related to Neurofibromatosis type 1, are not cancerous, people with the condition should be monitored for the development of these tumors. Some non-cancerous tumors cause problems, such as loss of vision with optic pathway gliomas or nerve damage with neurofibromas. It is also important to carefully monitor neurofibromas for signs that might show that they have become cancerous. The goal of screening is to find and treat tumors early to allow the best outcome for patients.
How is genetic testing for Neurofibromatosis type 1 done?
The health care provider may suspect Neurofibromatosis type 1, after looking at a person’s medical or family history. In most cases, a health care provider or genetic counselor will ask questions about a person’s health and the health of other family members.
What You Need to Know
Neurofibromatosis type 1 (NF1) is a condition caused by a change in a specific gene, and therefore can be inherited and passed on.
What is NF1?
Neurofibromatosis type 1 (also called Von Recklinghausen’s disease, Von Recklinghausen neurofibromatosis and peripheral NF) is one of the most commoninherited disorders and affects about one in every 3,000 people. NF1 ranges from mild to severe, and can cause more symptoms in some people than in others.
NF1 Symptoms and Diagnosis
Neurofibromatosis type 1 symptoms can involve many different parts of the body. A doctor with expertise in NF1 can provide an accurate diagnosis based on the symptoms, family history, as well as genetic testing and other imaging tests or biopsy.
Neurofibromatosis Type 1 Treatment
While there is no treatment that can reverse NF1, its signs and symptoms can be addressed. Tumors, in particular, may warrant chemotherapy, radiation, surgery or a combination of treatments. In about 60% of people with NF1, symptoms are mild and can be monitored without the need for treatment.
What is the most serious problem with NF1?
One of the most serious problems that can affect a person with NF1 is a malignant peripheral nerve sheath tumour (MPNST). MPNSTs are a type of cancer that develops within a plexiform neurofibroma. It's estimated that people with NF1 have around a 15% chance over their lifetime of developing a MPNST.
What are the symptoms of plexiform neurofibromas?
They may sometimes cause symptoms including pain, weakness, numbness, bleeding, or problems with the bladder or bowels, such as urinary tract infections or constipation.
Why is my NF1 high?
Some children with NF1 develop high blood pressure. High blood pressure may be caused by narrowing of the artery to the kidney (renal artery stenosis). This requires specialist treatment if it's found to be causing your child's high blood pressure. High blood pressure may also be caused by a phaeochromocytoma.
How many spots do you have with NF1?
The spots can be present at birth or develop by the time a child is 3 years old. During childhood , most children with NF1 will have at least 6 café au lait spots around 5mm across. These grow to about 15mm during adulthood . The number of spots someone has is not related to the severity of the condition.
What is a coffee coloured patch?
Coffee-coloured patches. The most common symptom of NF1 is the appearance of painless, coffee -coloured patches on the skin, called café au lait spots. However, not everyone with café au lait spots has NF1. The spots can be present at birth or develop by the time a child is 3 years old.
What is the name of the tumor that is located at the back of the eye?
The optic pathway is located at the back of each eye and sends information from the eyes to the brain. This type of tumour is known as an optic pathway glioma (OPG).
What is the name of the tumor that grows on the skin of a child?
As a child gets older, usually during teenage years or early adulthood, they develop tumours on or under their skin (neurofibromas). These are caused by non-cancerous tumours that develop on the coverings of nerves. They may vary in size, from pea-sized to slightly bigger tumours. Some neurofibromas are purple.
What is the name of the genetic disorder that causes tumors to form on nerve tissue?
Neurofibromatoses are a group of genetic disorders that cause tumors to form on nerve tissue. These tumors can develop anywhere in the nervous system, including the brain, spinal cord and nerves. There are three types of neurofibromatosis: neurofibromatosis 1 (NF1), neurofibromatosis 2 (NF2) and schwannomatosis. NF1 is usually diagnosed in childhood, while NF2 and schwannomatosis are usually diagnosed in early adulthood.
How much risk of schwannomatosis is there?
Researchers currently estimate that the risk of inheriting schwannomatosis from an affected parent is about 15%.
What are the learning disabilities of NF1?
Learning disabilities. Impaired thinking skills are common in children who have NF1 but are usually mild. Often there is a specific learning disability, such as a problem with reading or mathematics. Attention-deficit/hyperactivity disorder (ADHD) and speech delay also are common.
Why is NF1 head larger than average?
Larger than average head size. Children with NF1 tend to have a larger than average head size due to increased brain volume.
What is neurofibromatosis caused by?
Neurofibromatosis is caused by genetic defects (mutations) that either are passed on by a parent or occur spontaneously at conception. The specific genes involved depend on the type of neurofibromatosis:
When is NF1 diagnosed?
NF1 is usually diagnosed in childhood, while NF2 and schwannomatosis are usually diagnosed in early adulthood. The tumors in these disorders are usually noncancerous (benign), but sometimes can become cancerous (malignant). Symptoms are often mild.
How many cafe au lait spots are there?
Signs and symptoms include: Flat, light brown spots on the skin (cafe au lait spots). These harmless spots are common in many people. Having more than six cafe au lait spots suggests NF1. They are usually present at birth or appear during the first years of life. After childhood, new spots stop appearing.
What causes NF1?
NF1 is caused by impairment in a gene that is responsible for a protein called neurofibromin.
How is NF1 treated?
Neurofibromatosis type 1 is a genetic disease, and unfortunately, there is no definitive cure for it. However, a child may be given symptomatic treatment and other supportive treatments for the following:
