The NUP160 gene helps build tiny gateways in each cell that control traffic between the nucleus, where DNA is stored, and the rest of the cell. Every cell in your body uses this gene to move important messages and proteins in the right direction. If the NUP160 gene does not work properly, this traffic can be disrupted, which may affect cell growth and early development. Rare disruptive variants in the NUP160 gene have been linked to developmental conditions in some families.
What is a gene?
Genes are stretches of DNA that hold instructions your cells use to make molecules or regulate processes in the body. Some genes provide the information needed to make proteins, the working parts of cells. Others mainly help direct when certain processes happen, where they happen, and how strongly they run. Together, genes affect how the body develops and works, and they can also shape how you respond to food, stress, or medications. To go deeper into this topic, you can find more in the LearnHub.
Overview
NUP160Gene function
What if the gene works
The NUP160 gene helps build nuclear pores, the gateways that move molecules in and out of a cell’s nucleus. This supports normal gene activity, cell growth, and everyday cell function.
Risk
What if the gene does not work
Milder variants in the NUP160 gene may partly weaken the cell’s gateway for moving proteins and RNA, while more severe variants can disrupt it more strongly. This can interfere with normal signaling and gene activity.
Treatment
What does that mean for your treatment
No treatment or management approach specific to the NUP160 gene is currently established in clinical guidelines. Drug choices are based on the person's condition and symptoms rather than on the NUP160 gene itself.
Conditions associated with NUP160
Gene function
What if the gene works
Your cells constantly move genetic messages and proteins in and out of the nucleus, the control center that stores DNA. The NUP160 gene helps create the tiny gateways that manage this traffic. When it works normally, these gateways stay organized so everyday cell activity can run smoothly.
The NUP160 gene helps build the nuclear pore complex (the tiny gateway system in the membrane around the nucleus). These gateways control what moves between the nucleus and the rest of the cell.
The protein from the NUP160 gene supports the movement of RNA messages (working copies of genetic instructions) and many proteins through these gateways. This controlled flow is a key part of what the NUP160 gene does in the body each day.
Its protein also helps new nuclear pores form and stay organized as cells go about routine activity. This keeps the cell's transport system orderly and ready for steady day to day use.
What is a variant?
Within a gene, a genetic variant is a small difference in its DNA sequence. These differences are common and help shape normal human diversity, including variation in 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 situations, however, a variant changes how a gene works more substantially and may contribute to or cause a genetic condition.
Genetic variants
What if the gene does not work
Understanding how NUP160 gene variants affect protein function starts with the way these changes can alter the NUP160 protein’s shape, stability, or ability to join other pore proteins. More disruptive variants may reduce the amount of working protein or weaken assembly of the cell’s nucleus transport gateway, while milder variants may leave some activity in place. In people with disease-causing variants, this functional drop can be linked to earlier or more severe kidney involvement.
How variants are linked to conditions
Pathogenic variants in the NUP160 gene can cause steroid-resistant nephrotic syndrome, a rare inherited kidney condition. In some families, NUP160 gene variants and inherited kidney disease are part of a broader syndrome with developmental differences. The kidney problems often involve protein leaking into the urine, swelling, scarring in the kidney filters, and falling kidney function.
A variant is not necessarily a diagnosis
Gene variants are a normal part of human biology and are widely found in the general population. Most do not have a direct effect on health and instead 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 part. In some situations, though, a single 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 NUP160 gene. If genetic testing has found a change in NUP160, a doctor or genetic counselor can help explain what that result may mean for your personal or family risk.
Inheritance of NUP160 variants
For families asking about the NUP160 gene inheritance pattern, the well-established pattern for NUP160-related conditions is autosomal recessive. This means a person usually inherits one NUP160 variant from each parent. Parents who each carry one variant are typically unaffected, and with each pregnancy they have a 25% chance of having a child with the condition, a 50% chance of having a child who is a carrier, and a 25% chance of having a child with no familial variant.
What does my NUP160 result mean for my family?
For NUP160, the main known family pattern is recessive, which usually means parents are healthy carriers and brothers or sisters could also be affected or be carriers. Other close relatives on both sides of the family may be carriers too. For many living with a NUP160-related condition, children would usually be carriers unless the other parent also carries a changed NUP160 copy.
Genetic information
Genetic testing
How you find out about variants
To find out about NUP160 variants, genetic testing usually uses a blood or saliva sample. A lab may study the NUP160 gene through a multigene panel, exome sequencing, or genome sequencing, then compare your DNA with a reference sequence. Results may show a benign variant, a variant of uncertain significance, or a pathogenic variant.
When should I consider getting a genetic test?
Genetic testing for the NUP160 gene may be worth discussing if someone has unexplained kidney disease, especially heavy protein in the urine that does not improve with steroid treatment, or a family history of early serious kidney problems. A test can help show whether an inherited NUP160 change is part of the cause.
A genetic result is only one part of your health story
Genetic test results can be informative, but how much they reveal varies by the condition and the specific type of variant. Many factors, including lifestyle, environment, age, and medical history, also shape how the body functions over time. For some conditions, especially those influenced by many genes, genetic information offers context rather than certainty and is best interpreted alongside other parts of care. In other situations, a genetic result may give a clear answer. In areas like medication response, these results can also help put individual experiences into context.
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 absorbs, breaks down, or moves a drug, so the same treatment may work better for one person and less well for another. These differences are common and can influence both benefit and the chance of side effects or sensitivity to a medication.
What is Pharmacogenetics?
Pharmacogenetics examines how genetic differences affect the way people respond to medications. It studies links between genes and drugs to help explain why the same treatment may work differently from one person to another. For many medicines, genes influence both how the body processes a drug and how strong its effects are. This information can support treatment decisions that are more informed and more personalized.

Drugs influenced by the NUP160 gene
When should I seek medical advice?
There is not yet a broadly confirmed role for this gene in guiding medication choice or response, so general questions about treatment, side effects, or new symptoms are best discussed with your doctor.
