Your cells depend on the NUP188 gene when they need to move molecules in and out of the nucleus, the control center that stores DNA. It also helps keep the nuclear pore, the gateway in the nuclear membrane, stable. If this gene does not work properly, cells can struggle to control gene activity and normal development. Rare disruptive variants in the NUP188 gene have been linked to developmental differences and some conditions present from birth.
What is a gene?
Genes are stretches of DNA that hold instructions your cells use to make molecules or regulate activities in the body. Some genes carry the information needed to produce proteins, the parts of cells that do much of the work. Other genes mainly direct when and where certain processes happen, and how strongly they take place. Together, genes affect how the body develops and works, and they can influence how you respond to food, stress, or medications. For a more detailed look at this topic, you can find more in the LearnHub.
Overview
NUP188Gene function
What if the gene works
The NUP188 gene helps build and support nuclear pores, the gates that control movement in and out of a cell’s nucleus. This helps cells manage routine gene activity and protein traffic.
Risk
What if the gene does not work
Milder to more severe variants in the NUP188 gene can weaken how nuclear pores are built and maintained. This may disrupt the movement of molecules into and out of the nucleus and alter signals that help cells work normally.
Treatment
What does that mean for your treatment
No NUP188-specific treatment or drug-selection approach is currently established; care is guided by a person’s symptoms and standard supportive management.
Gene function
What if the gene works
Every cell needs a steady flow of materials into and out of its nucleus, the compartment that stores DNA. The NUP188 gene helps build and support the tiny gateways that handle this movement. Understanding what the NUP188 gene does in the body helps explain how cells keep their control center organized and running smoothly.
NUP188 helps form nuclear pores, tiny openings in the membrane around the nucleus. These openings give the nucleus stable entry and exit points for routine cell traffic.
Its protein helps these pores manage which proteins and RNA (working copies of genetic instructions) move in or out. This keeps messages and cell tools traveling in an orderly way.
NUP188 also helps the membrane around the nucleus keep its shape and organization. This supports a steady, well arranged control center during everyday cell activity.
What is a variant?
A genetic variant is a minor change in a gene’s DNA sequence. These changes are common and help shape normal differences between people, including appearance, metabolism, and the way the body responds to environmental influences. Many variants do not cause any noticeable effect and are simply part of 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 NUP188 gene can alter the protein's shape, stability, or ability to join the nuclear pore complex. This is how NUP188 gene variants affect the nuclear pore complex at a cell level. Milder variants may partly weaken protein interactions, while more severe variants can shorten the protein, reduce its amount, or stop normal assembly, which can disrupt transport between the nucleus and the rest of the cell.
How variants are linked to conditions
Variants in the NUP188 gene do not yet have a broadly confirmed link to a specific health condition, though research on NUP188 gene variants and health conditions is still developing. Anyone with a confirmed NUP188-related diagnosis should rely on guidance from their doctor or genetic counselor rather than general information.
A variant is not necessarily a diagnosis
Genetic variation is a routine part of human biology and is widely found in the general population. Most variants do not directly affect health and instead reflect natural human diversity. For many genes, having a variant associated with a condition indicates a possible link rather than a definite diagnosis, especially when multiple 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 is not yet broadly confirmed evidence on specific factors that increase or reduce risk related to the NUP188 gene. For many living with a NUP188-related condition, risk is mainly linked to the genetic change itself rather than lifestyle or environmental factors, and a doctor or genetic counselor can help explain personal and family risk.
Inheritance of NUP188 variants
There is not yet a broadly confirmed, single disease specific inheritance pattern for the NUP188 gene that is used routinely in patient care, so how NUP188 gene variants are inherited is still being clarified as research develops. NUP188 is located on an autosome, which means everyone inherits one copy from each parent. In general, a variant in this gene could be passed from either parent to a child, regardless of sex.
What does my NUP188 result mean for my family?
There isn't yet a broadly confirmed inheritance pattern tied to a specific condition for NUP188, though this understanding can change as research develops. If you have a specific NUP188 result and questions about what it could mean for your family, a doctor or genetic counselor can give guidance tailored to your situation.
Genetic information
Genetic testing
How you find out about variants
To look for changes in the NUP188 gene, doctors use NUP188 genetic testing, usually on a blood or saliva sample. The lab reads the gene’s DNA sequence and checks for variants, then compares any findings with established medical databases to help classify whether a variant is linked to a genetic condition or is unlikely to affect health.
When should I consider getting a genetic test?
There is not yet a broadly established NUP188-specific reason for genetic testing on its own. Testing may still be considered with a doctor or genetic counselor if there is a strong personal or family history of a rare inherited condition, especially when NUP188 is included on a broader gene panel.
A genetic result is only one part of your health story
Genetic test results can provide meaningful insight, but how much they explain varies with the condition and the kind of variant involved. Many factors, including lifestyle, environment, age, and medical history, also shape how the body works over time. In some conditions, especially those influenced by many genes, genetic information provides context rather than certainty and is best understood together with other parts of care. In other situations, a genetic result can offer a clear answer. In areas such as medication response, these results can also help make sense of individual experiences.
Pharmacogenetics
How variants shape your response to medicine
Genetic variation can affect how people respond to medicines. Small differences in DNA can change how the body breaks down a drug, moves it through the body, or responds to it where it acts. That helps explain why the same medication may work well for one person, seem less effective for another, or cause more side effects in someone else. These inherited differences are common and are just one part of the picture, alongside age, liver and kidney function, other medicines, and overall health.
What is Pharmacogenetics?
Pharmacogenetics examines how differences in a person’s genes can shape their response to medicines. It studies gene drug patterns to help explain why the same treatment may work differently from one person to another. For many medications, genes influence either how strongly a drug works or how the body processes it. This information can help support more informed, individualized treatment decisions.

Drugs influenced by the NUP188 gene
When should I seek medical advice?
There is not yet a broadly confirmed role for this gene in guiding medication choice or dose. If you have concerns about side effects, how well a medicine is working, or any other treatment questions, discuss them with your doctor.
