The NUP58 gene helps build the tiny gateways that control movement of proteins and genetic messages in and out of a cell’s nucleus, where DNA is stored. This gene plays an important role in keeping that traffic smooth so cells can work, grow, and divide normally. If the NUP58 gene does not work properly, this transport system may be disrupted, which can interfere with normal cell function. NUP58 is mainly discussed in research rather than public culture.
What is a gene?
Genes are sections of DNA that give your cells instructions to make molecules or regulate processes in the body. Some genes carry the information needed to produce proteins, which are the parts of cells that do much of the work. Other genes are mainly involved in controlling when certain processes happen, where they happen, and how active they are. Together, genes affect how the body develops and functions, and they can influence how you respond to food, stress, or medications.

Overview
NUP58Gene function
What if the gene works
The NUP58 gene helps build nuclear pores, the channels that connect a cell’s nucleus with the rest of the cell. It supports the controlled movement of RNA and proteins in and out of the nucleus.
Risk
What if the gene does not work
Changes in the NUP58 gene can range from milder to more severe and may partly reduce or more strongly disrupt transport through nuclear pores, affecting how cells move RNA and proteins between the nucleus and cytoplasm.
Treatment
What does that mean for your treatment
For a pathogenic or loss-of-function variant in the NUP58 gene, no NUP58-specific treatment or management approach is currently established. Care is based on the person's symptoms rather than on a drug choice tied to this gene.
Gene function
What if the gene works
Inside each cell, there is constant traffic between the nucleus, where DNA is kept, and the rest of the cell. The NUP58 gene helps run this traffic through tiny openings in the membrane around the nucleus. Its protein is part of the gateway that lets important molecules pass in a controlled way. Seeing how the NUP58 gene works in the nuclear pore makes its day to day role easier to picture.
The NUP58 gene helps important proteins enter the nucleus and helps RNA messages leave it. This steady exchange lets cells turn genetic instructions into everyday work.
Its protein forms part of the middle of the nuclear pore, the channel that molecules pass through. This helps keep the opening organized and flexible as molecules move across.
Its protein works with other pore proteins to support controlled movement rather than a wide open leak. That balance helps the nucleus stay separate while still sharing what the cell needs.
What is a variant?
A genetic variant is a minor difference in the DNA sequence within a gene. These differences are common and are part of normal human diversity, including traits such as appearance, metabolism, and the way the body responds to environmental factors. Many variants do not lead to any noticeable changes and simply represent natural genetic variation. In some situations, though, a variant can affect how a gene works more substantially and may contribute to, or directly cause, a genetic condition.
Genetic variants
What if the gene does not work
NUP58 gene variants can alter the shape or amount of the NUP58 protein, making it fit less well into the nuclear pore complex and disrupting transport between the nucleus and the rest of the cell. Milder changes may partly weaken protein stability or partner binding, while more severe variants can greatly reduce protein production or create a shortened protein with little activity. What happens if the NUP58 gene does not work depends on how much this transport system is impaired.
How variants are linked to conditions
Current evidence does not yet show a broadly confirmed link between the NUP58 gene and a specific inherited health condition, and research on NUP58 gene variants and disease is still developing. Anyone with a confirmed NUP58-related diagnosis should rely on guidance from their doctor or genetic counselor rather than general information.
A variant is not necessarily a diagnosis
Variants in DNA are a routine feature of human biology and are widespread across the population. Most do not directly affect health and instead represent normal human variation. For many genes, having a variant associated with a condition points to a possible link, not a certain diagnosis, particularly when several genes and environmental influences play a role. In some situations, though, one well-characterized variant in a particular 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 the NUP58 gene. If a change in NUP58 has been found in you or your family, a doctor or genetic counselor can help explain what it may mean for your personal risk.
Inheritance of NUP58 variants
There is not yet a broadly confirmed Mendelian inheritance pattern for NUP58-related disease, so how variants of the NUP58 gene are inherited in a clinical setting is still being clarified. The NUP58 gene is located on chromosome 13, which is an autosome, so each person inherits one copy from each parent. In general, that means either parental copy could carry a variant, but the health effect depends on the specific variant and whether it is clearly linked to a condition.
What does my NUP58 result mean for my family?
There is not yet a broadly confirmed inheritance pattern tied to a specific condition for the NUP58 gene, though this understanding can change as research develops. If you have a specific NUP58 result and questions about what it could mean for your family, a doctor or genetic counselor can help explain it in the context of your personal and family history.
Genetic information
Genetic testing
How you find out about variants
To look for changes in the NUP58 gene, doctors use NUP58 genetic testing on a blood or saliva sample, usually with gene panel, exome, or genome sequencing. The lab reads your DNA and compares it with a reference sequence to identify variants and show whether a finding may help explain a diagnosis.
When should I consider getting a genetic test?
There is not yet a broadly established reason to test the NUP58 gene on its own in routine care. Testing decisions are usually based on your symptoms, medical findings, and family history, ideally with a doctor or genetic counselor.
A genetic result is only one part of your health story
A genetic result can be informative, but how much it reveals depends on the condition and the specific type of variant involved. Over time, many factors, including lifestyle, environment, age, and medical history, influence how the body functions. For some conditions, especially those shaped by many genes, genetic information provides context rather than certainty and is best considered alongside other parts of care. In other situations, a genetic result may offer a clear answer. In areas such as medication response, genetic 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. This helps explain why the same treatment works well for one person, seems weaker for another, or causes more side effects in someone else. Part of the difference comes from inherited changes that influence how the body breaks down, moves, or responds to a drug, and this kind of variation is common.
What is Pharmacogenetics?
Pharmacogenetics examines how genetic variation shapes a person’s response to medications. It looks at gene drug relationships to help explain why the same treatment may work differently from one person to another. For many medicines, genes influence how strongly a drug works or how the body handles it. This information can support more personalized and better informed treatment decisions. More about this topic is available in the LearnHub.
Drugs influenced by the NUP58 gene
When should I seek medical advice?
There is not yet a broadly confirmed role for this gene in guiding how medicines are chosen or used, so questions about your health, treatment, or possible side effects are best discussed with your doctor.
History
In recent decades, awareness of the NUP58 gene’s place in cell biology has grown through research on the nuclear pore complex, a structure scientists began dissecting in detail in the late 20th century. NUP58 was identified as one of several genes encoding pore proteins, called nucleoporins, as researchers worked to map the parts of this gateway between the cell nucleus and the rest of the cell. From these first observations, research expanded steadily. Early studies helped place the NUP58 gene within a small group of pore genes that shape the central channel of the complex. Its history is mainly tied to this broader effort to understand how material moves in and out of the nucleus, rather than to a single public event or landmark medical discovery.
