Is neurofibromatosis more common in males or females?

NF1 is a rare disorder that affects males and females in equal numbers. NF1 affects all races and ethnic groups equally and is estimated to occur in 1 in 2,500 to 3,000 births.

Who is most likely to get neurofibromatosis?

The only true risk factor for developing neurofibromatosis is having a parent who also has the condition. In nearly half of all cases of type 1 and type 2 neurofibromatosis, and in around 15 percent of schwannomatosis cases, the condition is passed down from parent to child.

Where is neurofibromatosis type 1 most common?

Most of the brain tumors that occur in neurofibromatosis type 1 are low-grade astrocytomas. They can occur anywhere in the brain, but most often occur along the optic pathway, and therefore can affect vision. Most of these tumors occur by 6 years of age.

How common is neurofibromatosis in the world?

The Neurofibromatoses are genetically-determined disorders which affect more than 2 million people worldwide; this makes NF more prevalent than cystic fibrosis, Duchenne muscular dystrophy, and Huntington's Disease combined.

Does neurofibromatosis affect a certain group of people?

Neurofibromatosis, pronounced neuro-fibroma-tosis, is a genetic disorder of the nervous system that causes tumors to form on the nerves anywhere in or on the body at any time. NF affects all races, all ethnic groups and both sexes equally. NF affects more people than Cystic Fibrosis and Muscular Dystrophy combined!

Are There "Male" and "Female" Brains?

Can you have NF1 without café-au-lait spots?

It is very common for people to have a few café-au-lait spots on their bodies without having an underlying condition like neurofibromatosis type 1 (NF1). People diagnosed with NF1 usually have more than six café-au-lait spots on their bodies along with additional symptoms related to their diagnosis.

Are café-au-lait spots normal?

Café au lait spots are harmless and normal, with some people having anywhere from one to three spots. But sometimes, these spots can indicate an underlying genetic problem.

Can NF1 be detected during pregnancy?

Neurofibromatosis screening tests can be performed prenatally (while a fetus is in utero) to help determine whether an individual will be born with the condition. However, prenatal neurofibromatosis tests are typically only given when one or both parents have the condition.

Is NF1 fatal?

Neurofibromatosis Type 1 (NF1)

In most cases, symptoms of NF1 are relatively mild, allowing patients to live normal and productive lives. However, the disorder can also be debilitating and, in some cases, life-threatening.

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.

When are most kids diagnosed with NF1?

Because children with NF1 get more signs and symptoms as they grow, the diagnosis may not be made right away. Almost all kids with the condition are diagnosed by the time they're 8 years old.

Can café-au-lait spots appear later in life?

The size of café au lait spots can also vary. Spots can be as small as a half centimeter. The spots are usually present at birth but may develop later in life. Café au lait spots are harmless and normal, with some people having anywhere from one to three spots.

What age do café-au-lait spots appear?

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.

Is neurofibromatosis recessive or dominant?

Inheritance. Neurofibromatosis type 1 is considered to have an autosomal dominant pattern of inheritance. People with this condition are born with one mutated copy of the NF1 gene in each cell. In about half of cases, the altered gene is inherited from an affected parent .

Can you be a carrier of NF1 and not have it?

NF does not skip generations which means you cannot be a carrier if you do not have it, even if one or more parents have NF. NF1 and NF2 are therefore said to have “complete penetrance”.

Are neurofibromas common?

Intramuscular neurofibromas grow on small nerves in the muscles. This type can cause pain. Spinal neurofibromas grow on the nerves exiting the spine. They are more common in adults than children, and if they grow large enough, spinal neurofibromas can compress nerves and cause pain, numbness or weakness.

Does NF1 qualify for 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.

Can NF1 tumors be removed?

If cancerous tumors develop with neurofibromatosis—for example, malignant plexiform neurofibromas, which can develop in the arms, legs, or trunk—they can also be surgically removed. For cancerous tumors, surgery may be combined with other treatments for cancer.

What is the average lifespan for a person 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.

Does NF1 cause infertility?

While fertility does not seem to be impaired in neurofibromatosis, these patients experience a higher-than-expected rate of first-trimester spontaneous abortions (20.7%), stillbirths (8.7%) and intrauterine growth retardation (13.0%).

When do freckles appear in NF1?

The freckles usually start to develop around the age of three and become more obvious as the child grows. The unusual areas of freckling have, until very recently, been considered to be characteristic of just NF1. However they are also present in a related condition called Legius syndrome (discussed below).

How do I verify NF1?

Do neurofibromas go away?

Neurofibromas often start to show up during puberty. They may keep getting bigger for a while but will eventually stop growing. Typically, people gradually develop new ones as they get older.

How do you get rid of NF1 bumps?

There is no known treatment or cure for neurofibromatosis or schwannomatosis. Medication can be prescribed to help with pain. In some cases, growths may be removed surgically or reduced with radiation therapy.
