The NUP98 gene helps control traffic into and out of the cell’s nucleus, where DNA is stored. The protein made by this gene helps your cells regulate which genes are turned on and off. If the NUP98 gene does not work properly, cells may grow or develop in less controlled ways, and some acquired variants involving this gene are linked to certain leukemias. This gene is mainly known in medical care and research rather than popular culture.
What is a gene?
Genes are stretches of DNA that carry instructions your cells use to make molecules or regulate processes in the body. Some genes hold the directions for making proteins, the parts of cells that do much of the work. Other genes mainly control when certain processes happen, where they happen, and how strongly they are carried out. Together, genes affect how the body develops and works, and they can influence how you respond to food, stress, or medications. More information on this topic is available in the LearnHub.
Overview
NUP98Gene function
What if the gene works
The NUP98 gene helps build the gates that control traffic into and out of a cell’s nucleus. This supports normal gene activity and helps cells grow and divide in an organized way.
Risk
What if the gene does not work
DNA changes in the NUP98 gene can range from milder to more severe. The best-known effects are DNA rearrangements linked to blood cancers, especially acute leukemia, and the exact cancer type and course can vary.
Treatment
What does that mean for your treatment
No NUP98-specific treatment or management approach is currently established. In cancer care, changes involving the NUP98 gene, especially NUP98 fusions, are being studied as prognostic markers and possible drug targets in some leukemias.
Gene function
What if the gene works
Every cell needs a steady flow of proteins and genetic messages between its control center and the rest of the cell. The NUP98 gene helps manage this traffic at gateways around the nucleus. When it works properly, this movement stays selective, organized, and well timed.
The NUP98 gene helps control the movement of proteins and RNA through the gateways linking the nucleus with the rest of the cell. This keeps key cell messages and tools moving in an orderly way.
The NUP98 protein helps form a flexible filter inside each nuclear gateway. This filter allows the right cargo to pass with transport helpers while limiting stray molecules from crossing.
The NUP98 gene supports the release of newly made RNA from the nucleus so it can be used to build proteins. This is a central part of how the NUP98 gene helps move molecules in and out of the nucleus.
What is a variant?
A genetic variant is a minor change in a gene’s DNA sequence. These changes are common and help explain normal differences among people, such as appearance, metabolism, or the way the body responds to environmental influences. Many variants do not have any noticeable effect and are simply part of natural genetic variation. In some situations, though, a variant can change how a gene works more substantially and may contribute to or cause a genetic condition.
Genetic variants
What if the gene does not work
Variants in the NUP98 gene often change the protein’s shape, reduce its stability, or create an abnormal fusion with another gene. In plain terms, how NUP98 gene variants affect cell function depends on the change: milder variants may only partly disrupt protein transport and gene control, while more severe variants or fusion events can strongly alter how genes are switched on and off. In blood-forming cells, these stronger changes are linked to earlier or more aggressive leukemia features.
How variants are linked to conditions
Most established disease links for the NUP98 gene involve acquired changes in blood-forming cells rather than inherited variants. NUP98 rearrangements are strongly associated with several blood cancers, especially acute myeloid leukemia and myelodysplastic syndromes, and they are also seen in some cases of T cell acute lymphoblastic leukemia. In practice, NUP98 gene variants linked to leukemia usually help classify the cancer rather than predict that a healthy person will develop it.
A variant is not necessarily a diagnosis
Genetic variants are a routine feature of human biology and are widely found across the general population. Most do not directly affect health and simply contribute to normal human diversity. For many genes, having a variant associated with a condition points to a possible link rather than a certain diagnosis, particularly when several genes and environmental influences play a part. In some situations, though, one well-characterized variant in a specific gene is enough to confirm a diagnosis.
Are there things that can increase or change my risk?
There is not yet broadly confirmed evidence on specific factors that increase or reduce health risk related to NUP98 itself. If NUP98 is part of your genetic results, a doctor or genetic counselor can help explain what it may mean in the context of your personal and family history.
Inheritance of NUP98 variants
There is not yet a broadly confirmed inherited disease pattern for the NUP98 gene, so how NUP98 variants are inherited is still being defined for health conditions linked to this gene. Much of the medical literature on NUP98 involves changes that arise in blood cells during a person’s lifetime rather than variants passed down through families. The NUP98 gene is located on chromosome 11, which is an autosome, so each person inherits one copy from each parent.
What does my NUP98 result mean for my family?
There is not yet a broadly confirmed inherited pattern linking NUP98 to a specific family-run condition in the way seen with some other genes. If you have a NUP98 result and want to know what it could mean for close relatives, a doctor or genetic counselor can explain it in the context of the exact finding and your family history.
Genetic information
Genetic testing
How you find out about variants
To look for changes in the NUP98 gene, labs study DNA from blood or saliva, and sometimes bone marrow or tumor samples when doctors are checking for an acquired cancer change. This is how NUP98 genetic testing works: the lab reads the gene’s DNA to look for small variants or larger rearrangements and compares any finding with established medical evidence.
When should I consider getting a genetic test?
Testing may be considered if someone has leukemia or strong signs of a blood cancer, because changes involving the NUP98 gene can help classify the cancer and guide care. These changes are usually found in the cancer cells themselves rather than being inherited through a family.
A genetic result is only one part of your health story
Genetic findings can provide useful insight, but how much they reveal depends on the condition and the kind of variant involved. Over time, many factors, including lifestyle, environment, age, and medical history, affect how the body works. For some conditions, especially those shaped by many genes, genetic information offers context rather than certainty and is best understood together with other aspects of care. In other situations, a genetic result may give a clear answer. In areas like medication response, genetic findings can help put individual experiences in perspective.
Pharmacogenetics
How variants shape your response to medicine
Genetic variation can affect how your body handles medicines, so the same treatment may work differently from one person to another. Some people break down a drug more slowly or more quickly, while others may be more or less likely to notice side effects. These differences are common and can influence how well a medicine works or how sensitive someone is to it.
What is Pharmacogenetics?
Pharmacogenetics examines how genetic differences affect the way people respond to medications. It studies connections between genes and drugs to help explain why the same treatment can work differently from one person to another. For many medicines, genes influence both how strongly a drug works and how the body handles it. This information can support treatment choices that are more informed and more individualized.

Drugs influenced by the NUP98 gene
When should I seek medical advice?
There is not yet a broadly confirmed role for this gene in guiding medication choices, so general questions about medicines, side effects, or your health are best discussed with your doctor. In blood cancer research, changes involving NUP98 have been linked to differences in how some leukemias respond to treatment, but this is not yet used as a routine guide for choosing medicines.
History
The NUP98 gene entered medical research in the 1990s, when scientists studying the cell nucleus identified it as part of the nuclear pore family. Soon after, cancer researchers found that changes involving the NUP98 gene could appear in certain leukemias, which made it an important marker in blood cancer genetics. Scientific classifications changed as researchers learned more about the gene. Over time, studies linked NUP98 to a growing list of gene fusions, helping doctors and researchers sort leukemia into more precise subtypes. From these first observations, research expanded steadily. Today, the NUP98 gene is mainly remembered in medical history for its role in improving how some blood cancers are recognized and categorized.
