The NUP35 gene helps build the nuclear pore, the gateway that controls what enters and leaves a cell’s nucleus. If it does not work properly, the nucleus can become less stable and cells may struggle to move important molecules in and out. This can disrupt how certain tissues work, especially those that need smooth, coordinated muscle activity. Rare harmful variants in the NUP35 gene have been linked to inherited intestinal movement problems, including chronic intestinal pseudo-obstruction.
What is a gene?
A gene is a stretch of DNA that holds instructions your cells use to make molecules or manage processes throughout the body. Some genes carry the code for producing proteins, which do much of the cell’s work. Others mainly regulate when, where, and how much certain processes occur. In combination, genes affect how the body grows and works, and they can influence your response to food, stress, or medicines. For a deeper look at this topic, more information is available in the LearnHub.
Overview
NUP35Gene function
What if the gene works
The NUP35 gene helps build and support nuclear pores, the tiny gateways that control movement in and out of a cell’s nucleus. This supports normal gene activity and helps keep the nucleus stable.
Risk
What if the gene does not work
Variants in the NUP35 gene are linked to chronic intestinal pseudo-obstruction, where the bowel moves poorly despite no physical blockage. Milder and more severe variants can affect when symptoms begin and how much of the digestive tract is involved.
Treatment
What does that mean for your treatment
No NUP35-specific treatment or drug-selection approach is currently established for people with a pathogenic or loss-of-function variant in the NUP35 gene.
Gene function
What if the gene works
Inside each cell, the NUP35 gene helps keep the border around the nucleus working smoothly. Its protein becomes part of tiny gateways that control movement in and out of the nucleus, the cell's control center. Understanding what the NUP35 gene does in your cells helps explain how cells keep important instructions organized and ready to use.
NUP35 helps assemble the nuclear pore complex, a group of tiny openings in the membrane around the nucleus. These openings act as controlled gates between the nucleus and the rest of the cell.
Its protein helps attach these pore structures to the nuclear membrane, the layer that surrounds the nucleus. This keeps the gateways positioned and supported during everyday cell activity.
By keeping each pore organized, NUP35 supports the movement of RNA and proteins into and out of the nucleus. This helps your cells send genetic instructions to the right place at the right time.
What is a variant?
A genetic variant is a slight difference in a gene’s DNA sequence. These differences are common and help explain normal human diversity, such as variation in appearance, metabolism, or how the body responds to environmental influences. Many variants do not cause any noticeable effect and simply reflect natural genetic variation. Sometimes, however, a variant can have a greater impact on how a gene functions and may contribute to or cause a genetic condition.
Genetic variants
What if the gene does not work
Variants in the NUP35 gene can change the NUP35 protein’s shape, stability, or binding surfaces, so it may not fit properly into the nuclear pore complex. This helps explain how NUP35 gene variants affect protein function inside cells. Milder variants may leave some activity in place, while more severe variants can sharply reduce protein interactions, mislocalize the protein, or create a shortened version that breaks down early.
How variants are linked to conditions
NUP35 does not yet have a broadly confirmed link to a specific health condition, so information about NUP35 gene conditions is still developing. If you have a reported variant in the NUP35 gene, your own results are best interpreted with your doctor or genetic counselor, who can place them in the context of your symptoms, family history, and the exact variant found.
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 have a direct effect on health and simply reflect natural human diversity. For many genes, carrying a variant associated with a condition indicates a possible link rather than a definite diagnosis, especially when several genes and environmental factors contribute. In some situations, however, 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 is not yet broadly confirmed evidence on specific factors that increase or reduce health risk related to the NUP35 gene. Personal risk depends mainly on the exact gene change, family history, and the health condition being considered.
Inheritance of NUP35 variants
For families looking into the NUP35 inheritance pattern, there is not yet a broadly confirmed disease specific Mendelian pattern that clinicians use in routine care. Research on NUP35 is still developing, so any link between inherited variants and a clearly defined human condition remains unsettled. The NUP35 gene is located on chromosome 2, which is an autosome, so each person inherits one copy from each parent.
What does my NUP35 result mean for my family?
There is not yet a broadly confirmed inheritance pattern tied to a specific health condition for the NUP35 gene, and this picture may become clearer as research grows. If you have a specific NUP35 result and want to understand what it could mean for close relatives, a doctor or genetic counselor can explain it in the context of your family history and the exact change found.
Genetic information
Genetic testing
How you find out about variants
To find out whether you carry a variant in the NUP35 gene, doctors use genetic testing, usually with a blood or saliva sample. Genetic testing for the NUP35 gene may be done on its own or as part of a broader panel, exome, or genome test, and the lab checks your DNA for variants.
When should I consider getting a genetic test?
NUP35 testing is not usually done on its own. Genetic testing decisions are usually based on your symptoms, medical findings, and family history, together with a doctor or genetic counselor.
A genetic result is only one part of your health story
Genetic test findings can be very informative, but what they reveal depends on the condition and on the kind of variant identified. Over time, the way the body functions is also shaped by many other factors, including lifestyle, environment, age, and medical history. With some conditions, particularly those affected by many genes, genetic information provides context rather than certainty and makes the most sense when considered with the rest of a person’s care. In other situations, the result can give a clear answer. In areas like medication response, genetic findings may also help put personal experiences in context.
Pharmacogenetics
How variants shape your response to medicine
Genetic variation can affect how people respond to medicines. One person may break down a drug more slowly or more quickly than another, which can change how well it works or how likely side effects are. These differences are common and are one reason the same treatment can feel very different from person to person.
What is Pharmacogenetics?
Pharmacogenetics examines how genetic differences can affect a person’s response to medications. It looks at links between genes and drugs to help explain why the same treatment may work differently from one person to another. For many medicines, genes can influence both how strongly a drug works and how the body processes it. This information can help support treatment decisions that are more informed and more individualized. To explore this subject in greater detail, you can learn more in the LearnHub.
Drugs influenced by the NUP35 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 side effects, new symptoms, or whether a treatment is working are best discussed with your doctor.
