The NUP153 gene gives your cells instructions for part of the tiny gateway that controls movement in and out of the nucleus, where DNA is stored. The protein made by this gene helps your cells move key molecules to the right place and supports normal gene activity and cell division. If the gene does not work properly, this transport system can become less reliable, which can disrupt how cells grow and communicate. In some people, rare harmful variants have been linked to developmental and nervous system problems.
What is a gene?
Genes are stretches of DNA that carry instructions your cells use to make molecules or direct processes in the body. Some genes hold the code for producing proteins, which are the parts of cells that do much of the work. Other genes mainly regulate when certain processes happen, where they happen, and how strongly they are carried out. Taken together, genes affect how the body develops and works, and they can influence how you respond to food, stress, or medications.

Overview
NUP153Gene function
What if the gene works
The NUP153 gene helps build the pores that control traffic in and out of the cell nucleus. This supports normal gene activity and cell division.
Risk
What if the gene does not work
Changes in the NUP153 gene can weaken how the nuclear pore works, making it harder for molecules to move in and out of the cell nucleus. Milder and more severe variants may disrupt this transport to different degrees.
Treatment
What does that mean for your treatment
No treatment approach specific to a pathogenic variant in the NUP153 gene is currently established in clinical guidelines. The NUP153 gene is being studied in cancer and cell biology research as a possible biomarker and drug target, but this has not led to routine treatment decisions.
Gene function
What if the gene works
Your cells constantly move proteins and RNA into and out of the nucleus, the control center that stores DNA. The NUP153 gene helps manage this traffic at the nuclear pore, a gateway in the membrane around the nucleus. It also supports the pore’s structure and helps the nucleus keep its usual shape during everyday cell activity.
One of the main roles of the NUP153 gene is to help guide proteins and RNA through nuclear pores. This is a key part of what the NUP153 gene does in the body, because cells need this steady exchange to read genes and carry out daily work.
NUP153 helps form the inner side of the nuclear pore and supports its basket like structure. This helps keep the gateway organized so transport can happen in a controlled way.
Inside your cells, the NUP153 gene helps messenger RNA leave the nucleus after it is made from DNA. That step lets the cell use genetic instructions to build proteins in the right place.
This gene also helps the nucleus keep a stable form as cells go through normal activity. A well supported nucleus helps DNA stay organized and accessible when the cell needs it.
What is a variant?
A genetic variant is a small difference in the DNA sequence of a gene. These changes are common and are part of normal human diversity, including differences in appearance, metabolism, or how the body responds to environmental influences. Many have no noticeable effect and simply reflect natural genetic variation. In some cases, 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 NUP153 gene can change the protein’s shape, stability, or position at the cell’s nuclear pore, so it may not interact normally with its partner proteins. NUP153 gene variant effects on nuclear transport can range from mild weakening of these interactions to more severe loss of working protein. In some cells, stronger loss of function may also disrupt nuclear pore assembly and the controlled movement of RNA and proteins between the nucleus and the rest of the cell.
How variants are linked to conditions
Current evidence on how NUP153 gene variants are linked to conditions is still developing. NUP153 does not yet have a broadly confirmed link to a specific health condition, and anyone with a reported NUP153-related diagnosis should follow guidance from their doctor or genetic counselor rather than general information.
A variant is not necessarily a diagnosis
Genetic variants are a routine part of human biology and are widespread in the general population. Most do not directly affect health and simply contribute to natural human diversity. For many genes, having a variant associated with a condition indicates a possible link rather than a certain diagnosis, especially when several genes and environmental influences also play a part. In some cases, 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 NUP153 gene. Anyone with concerns about their personal or family risk can speak with a doctor or genetic counselor.
Inheritance of NUP153 variants
There is not yet a broadly confirmed Mendelian inheritance pattern tied to a specific human condition for the NUP153 gene, so how NUP153 gene variants are inherited in a disease setting is still being worked out. The NUP153 gene is located on chromosome 6, which is an autosome. In general, that means each person inherits one copy of the NUP153 gene from their mother and one copy from their father.
What does my NUP153 result mean for my family?
There is not yet a broadly confirmed inheritance pattern tied to a specific condition for NUP153, though this can change as research develops. If you have a NUP153 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
Genetic testing for NUP153 variants usually uses a blood or saliva sample to read the NUP153 gene and look for DNA changes. Results may show a clearly relevant variant, a benign finding, or a variant of uncertain significance, which means the lab found a change but its health effect is not yet clear.
When should I consider getting a genetic test?
There is not yet a broadly established, NUP153-specific reason for genetic testing in routine care. Decisions about testing are usually based on your symptoms and family history, together with a doctor or genetic counselor.
A genetic result is only one part of your health story
A genetic finding can provide useful insight, but how much it reveals depends on the condition and the kind of variant involved. Many factors, including lifestyle, environment, age, and medical history, influence how the body functions over time. For some conditions, particularly those shaped by many genes, genetic information offers context rather than certainty and is most helpful when considered with other parts of care. In other situations, a genetic result can give a clear answer. In areas like medication response, genetic results can help make sense of individual experiences.
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 but less well for another, or why some people are more likely to notice side effects. Part of this comes from inherited differences in how the body breaks down, moves, or responds to a drug. These differences are common and can influence both how well a medicine works and how sensitive someone is to it.
What is Pharmacogenetics?
Pharmacogenetics examines the ways genetic differences shape a person’s response to medications. By looking at relationships between genes and drugs, it helps explain why the same treatment can work differently in different people. With many medicines, genes influence both how the body handles a drug and how strong its effects may be. Understanding this can support treatment decisions that are better informed and more individualized. More detailed information on this topic is available in the LearnHub.
Drugs influenced by the NUP153 gene
When should I seek medical advice?
There is not yet a broadly confirmed role for this gene in predicting how medicines will work or what side effects they may cause. Questions about symptoms, treatment, or medication changes are best discussed with your doctor, who can look at your overall health and current medicines.
History
The NUP153 gene entered the scientific literature in the early 1990s, when researchers were identifying the proteins that make up the nuclear pore, the gateway between the cell nucleus and the rest of the cell. Initially understood only through visible traits, later recognized as tied to a specific gene, NUP153 became part of a broader effort to map the pore’s structure in detail. From these first observations, research expanded steadily as cell biology and genetic tools improved. Studies through the 1990s and 2000s helped place NUP153 among the better characterized nucleoporin genes. Its history is mainly a scientific one, rooted in the step by step uncovering of how cells organize and move materials across the nucleus.
