The NUP214 gene helps build the nuclear pore, a gateway that controls movement of proteins and genetic messages in and out of a cell’s nucleus. The protein made by this gene helps your cells keep growth and gene activity organized. If NUP214 does not work properly, cells can have trouble moving key materials where they are needed, which may disrupt normal cell division. In medicine, NUP214 is best known because certain acquired variants involving this gene are linked to some leukemias.
What is a gene?
Within your DNA, each gene is a section that holds instructions cells can use to make molecules or regulate processes throughout the body. Some genes give the directions for building proteins, the functional parts of cells. Others are used mainly to control when specific processes take place, where they occur, and how strongly they operate. Taken together, genes affect how the body develops and works, and they can influence your response to food, stress, or medications.

Overview
NUP214Gene function
What if the gene works
The NUP214 gene helps build nuclear pores, the gateways between a cell’s nucleus and cytoplasm. Its protein supports controlled movement of genetic messages and proteins, helping cells coordinate normal growth and daily activity.
Risk
What if the gene does not work
Certain variants involving the NUP214 gene, especially gene fusions, are linked to leukemia, including acute myeloid leukemia and some T cell acute lymphoblastic leukemia. Effects can vary by the specific variant, which may influence how the disease develops and behaves.
Treatment
What does that mean for your treatment
No treatment or management approach is currently established specifically for pathogenic variants in the NUP214 gene. In leukemia research, NUP214 rearrangements can act as biomarkers and may help guide targeted therapy in selected cases.
Conditions associated with NUP214
Gene function
What if the gene works
Your cells constantly move proteins and genetic messages in and out of the nucleus, the control center that stores DNA. The NUP214 gene helps organize this traffic at small gateways in the nuclear membrane. When it is working normally, these exchanges stay orderly and efficient. This helps explain what the NUP214 gene does in moving proteins and genetic messages between the nucleus and the rest of the cell.
The NUP214 gene helps form part of the nuclear pore, a gateway through the membrane around the nucleus. Its protein sits near the outer side of this gateway and supports controlled movement of cell cargo.
Many proteins travel with carrier molecules that bring them to the nuclear pore. NUP214 helps these carriers dock, so materials can be dropped off or picked up in an organized way.
Your cells make RNA, a working copy of genetic instructions, inside the nucleus. NUP214 supports the step that moves some of these messages out to the rest of the cell, where proteins can then be made.
What is a variant?
A genetic variant is a small change in the DNA sequence within a gene. These changes are common and help explain normal human differences, such as appearance, metabolism, or how the body responds to environmental influences. Many variants do not have any noticeable effect and simply represent natural genetic variation. In some situations, however, a variant can more substantially change how a gene functions and may contribute to or cause a genetic condition.
Genetic variants
What if the gene does not work
How NUP214 gene variants affect cells depends on the type of change. Milder variants may reduce the stability or placement of the NUP214 protein at the nuclear pore, while more severe variants can strongly disrupt its interactions and the movement of proteins and RNA between the nucleus and cytoplasm. Some structural changes also create NUP214 fusion proteins, which act abnormally and can have a different cellular effect.
How variants are linked to conditions
Changes involving the NUP214 gene are mainly linked to certain blood cancers rather than to a well-established inherited condition. In clinical practice, NUP214 gene variants linked to leukemia are most often gene rearrangements seen in T cell acute lymphoblastic leukemia and in some cases of acute myeloid leukemia or myelodysplastic disease. These are usually acquired changes in cancer cells, so they help classify the cancer but do not usually mean relatives share the same risk.
A variant is not necessarily a diagnosis
Genetic variants are a usual part of human biology and are widely seen in the general population. Most do not have a direct effect on health and simply reflect natural human diversity. For many genes, carrying a variant associated with a condition suggests a possible link rather than a definite diagnosis, especially when several genes and environmental factors also play a role. In some situations, though, a single well-characterized variant in a specific gene is enough to confirm a diagnosis.
Are there things that can increase or change my risk?
There isn't yet broadly confirmed evidence on specific factors that increase or reduce health risk related to the NUP214 gene. Risk depends mainly on the exact gene change and the condition involved, rather than on clear lifestyle or environmental factors. Anyone with concerns about personal or family risk should speak with a doctor or genetic counselor.
Inheritance of NUP214 variants
For people looking into how NUP214 gene variants are inherited, there is not yet a broadly confirmed single Mendelian inheritance pattern tied to a specific NUP214-related condition. Most well-known NUP214 changes have been described in cancer cells rather than passed through families in a clear inherited pattern. The NUP214 gene is located on chromosome 9, which is an autosome, so each person inherits one copy from each parent. This means any inherited NUP214 variant would generally be passed on in the same broad way as other genes on the numbered chromosomes.
What does my NUP214 result mean for my family?
There is not yet a broadly confirmed inherited pattern tied to a specific health condition for NUP214. Most well-known NUP214 changes are found only in cancer cells rather than passed through families, so what a NUP214 result means for relatives depends on the exact type of result.
Genetic information
Genetic testing
How you find out about variants
NUP214 genetic testing looks for changes in the NUP214 gene using DNA or chromosome testing on a blood, saliva, tumor, or bone marrow sample. Labs may use sequencing, FISH, PCR, or chromosome analysis to find variants or gene fusions, depending on whether the goal is to check for an inherited change or a blood cancer related change.
When should I consider getting a genetic test?
Testing for NUP214 is mainly considered during the work-up of certain blood cancers, especially some types of leukemia, to look for changes in the cancer cells. It is not usually part of routine inherited genetic testing, and family testing is uncommon unless a genetics team sees a specific reason.
A genetic result is only one part of your health story
Genetic results can be informative, but how much they reveal varies by the condition and the specific type of variant involved. Over time, the way the body works is shaped by many factors, including lifestyle, environment, age, and medical history. For some conditions, especially those influenced by many genes, genetic information offers context rather than certainty and is most useful when considered alongside other parts of care. In other situations, a genetic result can provide a clear answer. In areas like medication response, these results can also help put individual experiences into perspective.
Pharmacogenetics
How variants shape your response to medicine
Genetic variation can affect how people respond to medicines. Small differences in genes can change how the body breaks down a drug, moves it through the bloodstream, or responds to it at its target. This helps explain why the same treatment works well for one person, has less effect in another, or causes more side effects in someone else. These differences are common and are one reason medication response can vary from person to person.
What is Pharmacogenetics?
Pharmacogenetics examines how genetic differences can shape a person’s response to medications. It studies the relationship between genes and drugs to help explain why the same treatment may work differently from one person to another. For many medicines, genes can affect both how the body handles a drug and how strong its effects are. This information can support more informed, individualized treatment decisions.

Drugs influenced by the NUP214 gene
When should I seek medical advice?
There is not yet a broadly confirmed role for this gene in guiding everyday medication choices. Questions about side effects, new symptoms, or whether a treatment is working are best discussed with your doctor or pharmacist. In research on rare blood cancers, NUP214 changes have been studied for links to treatment response, but this has not become standard medication guidance.
History
The NUP214 gene entered the medical literature through studies of the nuclear pore, the structure that controls traffic in and out of the cell nucleus. In the 1990s, researchers also linked NUP214 to certain blood cancers after finding chromosome rearrangements that join it to other genes, including DEK and SET. From these first observations, research expanded steadily. These findings helped establish NUP214 as one of the recurring genes involved in leukemia-related fusion genes, which form when parts of two genes become abnormally joined. Over time, descriptions became more precise as laboratory methods improved and doctors learned to recognize these changes more reliably in patient samples.
