The NUP62 gene makes part of a tiny gateway that controls what moves in and out of the cell nucleus, where DNA is stored. The protein made by this gene helps your cells pass messages and other important materials to the right place. If this gene does not work properly, that traffic can be disrupted, which may affect brain development and movement. Some people with disease causing variants in the NUP62 gene develop early brain and nerve symptoms, but this gene is not widely known in popular culture.
What is a gene?
Genes are stretches of DNA that contain instructions your cells use to make molecules or manage processes in the body. Some genes provide the directions for producing proteins, the working parts of cells. Other genes mainly regulate when certain processes happen, where they happen, and how strongly they run. Together, genes affect how the body develops and functions, and they can also shape how you respond to food, stress, or medications. For a deeper look at this topic, you can find more in the LearnHub.
Overview
NUP62Gene function
What if the gene works
The NUP62 gene helps build nuclear pores, the gateways that control what moves in and out of a cell’s nucleus. This transport supports normal gene activity and other routine cell functions.
Risk
What if the gene does not work
When the NUP62 gene does not work properly, it can cause a rare childhood brain condition that affects movement. Milder or more severe variants may change when symptoms start and can lead to developmental delay, stiffness, or loss of skills.
Treatment
What does that mean for your treatment
No treatment or drug choice is currently guided specifically by a pathogenic or loss-of-function variant in the NUP62 gene. Management relies on treating the person's symptoms and complications rather than using a therapy aimed at NUP62.
Conditions associated with NUP62
Gene function
What if the gene works
Inside each cell, the NUP62 gene helps control traffic through the nuclear pore, the doorway between the nucleus and the rest of the cell. This keeps the right proteins moving in and RNA messages moving out. When this system runs smoothly, cells can read genes, build proteins, and carry out everyday tasks in a coordinated way.
This gene helps form the main passage that moves proteins and RNA between the nucleus and the rest of the cell. It supports the steady two-way flow cells need to read instructions and respond to daily demands.
Its protein is part of a filter that lets needed cargo pass while keeping out many molecules that should not drift in. This helps the nucleus stay protected while still communicating with the rest of the cell.
Its protein gives transport carriers a place to interact as they move cargo through the pore. That makes protein transport into and out of the nucleus more efficient and organized.
This gene supports the release of RNA instructions from the nucleus so they can be used to make proteins. By helping those messages reach the outer part of the cell, it supports normal cell activity.
What is a variant?
A genetic variant is a slight difference in the DNA sequence within a gene. These differences are common and help explain normal variation among people, such as in appearance, metabolism, or the way the body reacts to environmental influences. Many do not have any noticeable effect and are simply part of natural genetic diversity. In some situations, though, a variant changes how a gene works more significantly and can contribute to or cause a genetic condition.
Genetic variants
What if the gene does not work
Variants in the NUP62 gene can weaken the pore that controls movement between the nucleus and the rest of the cell. In how NUP62 gene variants affect nuclear pore transport, milder missense variants may partly change the protein’s shape or its binding to partner proteins, while more severe variants can sharply reduce NUP62 production or create a shortened protein that cannot join the pore. This often leads to less stable transport channels and poorer movement of key RNAs and proteins.
How variants are linked to conditions
Biallelic pathogenic variants in the NUP62 gene cause infantile bilateral striatal necrosis, a rare inherited condition that affects the brain and movement. People with NUP62 gene variants linked to infantile bilateral striatal necrosis may develop changes in muscle tone, unusual movements, and developmental difficulties, often starting in infancy or early childhood. This is the main well-established condition associated with this gene.
A variant is not necessarily a diagnosis
Gene variants are a routine part of human biology and are common throughout the general population. Most have no direct impact on health and simply reflect normal human diversity. For many genes, carrying a variant associated with a condition suggests a possible link rather than a certain diagnosis, especially when several genes and environmental influences play a role. 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 NUP62 gene. For many living with a NUP62 gene change, risk depends mainly on the specific variant and family pattern rather than lifestyle or everyday exposures, and a doctor or genetic counselor can help explain personal risk.
Inheritance of NUP62 variants
NUP62-related conditions are inherited in an autosomal recessive pattern. In the inheritance of the NUP62 gene variants, a child usually needs to inherit one altered copy from each parent to be affected. Parents who each carry one NUP62 variant are typically unaffected carriers, and with each pregnancy there is a 25% chance the child will inherit both altered copies, a 50% chance the child will be a carrier, and a 25% chance the child will inherit neither altered copy. This applies equally to sons and daughters.
What does my NUP62 result mean for my family?
For families with a disease-causing change in the NUP62 gene, the pattern is usually recessive, which means parents can be healthy carriers without knowing it. Brothers and sisters may also be affected or may be carriers, so close relatives may want to learn whether the same change runs in the family. Children of someone with a NUP62-related condition will usually be carriers unless the other parent also carries a disease-causing NUP62 change.
Genetic information
Genetic testing
How you find out about variants
Genetic testing for NUP62 variants usually analyzes DNA from a blood sample or cheek swab. A lab reads the NUP62 gene and classifies any variant by comparing it with established evidence, often as part of a larger gene panel or exome test.
When should I consider getting a genetic test?
Testing for the NUP62 gene may be considered when a baby or child has a rare inherited brain condition with early developmental delay, movement problems, or muscle stiffness, especially if close relatives have had similar symptoms. It is usually done as part of a broader genetic test ordered after specialist assessment.
A genetic result is only one part of your health story
A genetic finding can be informative, but how much it explains depends on both the condition and the kind of variant present. How your body functions over time is also shaped by many factors, including lifestyle, environment, age, and medical history. For certain conditions, particularly those affected by many genes, genetic information offers context rather than a definite answer and is most useful when considered together with other parts of care. In other situations, a genetic result can give a clear answer. In areas like 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 at the target tissue. This helps explain why the same treatment works well for one person, has less effect in another, or causes more side effects in someone else. These differences are common and are one part of the bigger picture, along with age, other health conditions, and other medicines.
What is Pharmacogenetics?
Pharmacogenetics examines the way genetic differences can affect a person’s response to medications. It studies gene-drug patterns to help explain why the same treatment may work differently in different people. With many medicines, genes can influence both how strongly a drug works and how the body handles it. This information can support treatment decisions that are more informed and more individualized. More detail on this topic is available in the LearnHub.
Drugs influenced by the NUP62 gene
When should I seek medical advice?
There is no broadly confirmed role for this gene in guiding medication choice at this time. If you have concerns about side effects, unusual reactions, or how a new medicine fits with your health history, speak with your doctor or pharmacist.
