The KIF25 gene helps make a motor protein that moves along the cell’s internal tracks and helps keep the machinery for cell division in the right place. This gene plays an important role in controlling when structures called centrosomes separate, which helps cells divide in an orderly way. If the KIF25 gene does not work properly, that timing can be disrupted, and cells may have trouble dividing normally.
What is a gene?
A gene is a piece of DNA that carries instructions your cells use to make molecules or regulate processes in the body. Some genes contain the directions for producing proteins, which are the parts of cells that do much of the work. Other genes mainly help determine when certain processes happen, where they occur, and how active they are. Taken together, genes influence how the body develops and functions, and they can affect how you respond to food, stress, or medications. For a deeper look at this topic, you can find more in the LearnHub.
Overview
KIF25Gene function
What if the gene works
The KIF25 gene helps organize tiny tracks inside cells during cell division. Its protein works like a motor on these tracks, helping position cell division structures and support orderly chromosome separation.
Risk
What if the gene does not work
Milder to more severe variants in the KIF25 gene may weaken this motor protein’s movement on microtubules, the cell’s internal tracks. This can upset centrosome positioning and make cell division less well coordinated.
Treatment
What does that mean for your treatment
No treatment or management approach tied specifically to the KIF25 gene is currently established for people with a pathogenic or loss-of-function variant.
Gene function
What if the gene works
Inside your cells, the KIF25 gene helps manage tiny protein tracks called microtubules, which act like internal rails. Its protein is especially important as cells get ready to divide, when structures need to be lined up in a controlled way. Understanding how the KIF25 gene helps organize cell division makes its day to day role easier to picture.
The KIF25 gene makes a motor protein that binds to microtubules, the cell's internal rails. Using energy, it moves along these tracks and helps shift cell structures into place.
One key job is keeping centrosomes, the structures that organize the division machinery, in a controlled arrangement before division begins. This helps the cell prepare for an orderly split.
By pulling on microtubules, this protein helps balance forces as a cell enters mitosis (cell division). That steady setup supports formation of the spindle, which guides chromosomes into the two new cells.
What is a variant?
A genetic variant is a minor change in a gene’s DNA sequence. These changes are common and are part of normal human diversity, including differences in appearance, metabolism, and the way the body responds to environmental factors. Many variants do not have any noticeable effect and simply represent natural genetic variation. Sometimes, 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 KIF25 gene can affect protein function by changing its shape, stability, or ability to bind cell scaffolding fibers and use energy for movement. KIF25 gene variants affect protein function along a spectrum, from milder changes that partly reduce activity to more disruptive variants that shorten the protein or stop it from being made. Some changes may also weaken how the protein reaches the right place in the cell or interacts with partner proteins.
How variants are linked to conditions
The KIF25 gene does not yet have a broadly confirmed link to a specific health condition, though research on KIF25 gene variants linked to conditions is still developing. If you have a reported variant in the KIF25 gene, your doctor or genetic counselor can explain what it may mean in the context of your symptoms and family history.
A variant is not necessarily a diagnosis
Genetic variants are a usual part of human biology and are widely found across the general population. Most do not directly affect health and simply reflect normal human diversity. For many genes, having a variant associated with a condition points to a possible link rather than a certain diagnosis, particularly when several genes and environmental influences play a role. In some situations, though, one 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 KIF25 gene. If a change in KIF25 has been found in your family or on testing, a doctor or genetic counselor can help explain what it may mean for your personal risk.
Inheritance of KIF25 variants
There is not yet a broadly confirmed, disease specific inheritance pattern for the KIF25 gene, so the inheritance of KIF25 gene variants is not currently described as clearly autosomal dominant, autosomal recessive, or X linked. The KIF25 gene is located on chromosome 6, which is an autosome, so each person inherits one copy from their mother and one copy from their father. As research develops, this picture may become more specific for particular variants or health conditions.
What does my KIF25 result mean for my family?
There isn’t yet a broadly confirmed inheritance pattern tied to a specific health condition for KIF25, and research on this gene is still developing. If you have a KIF25 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 exact finding and family history.
Genetic information
Genetic testing
How you find out about variants
To find out whether you carry a variant in the KIF25 gene, doctors use genetic testing for KIF25 variants on a blood or saliva sample. A lab reads the DNA code and compares it with the usual sequence to see whether a change is present, and the report explains whether the finding is known to affect health or is still uncertain.
When should I consider getting a genetic test?
There is not yet a widely accepted, KIF25-specific medical reason for genetic testing. Testing decisions are usually made with a doctor or genetic counselor based on your symptoms, family history, and whether a broader gene panel may be more useful.
A genetic result is only one part of your health story
A genetic result can provide useful insight, but how much it explains depends on the condition and the kind of variant involved. Over time, many factors shape how the body functions, including lifestyle, environment, age, and medical history. For some conditions, especially those influenced by many genes, genetic information offers context rather than certainty and is most helpful when considered together with other parts of care. In other situations, a genetic result may offer a clear answer. In areas like medication response, genetic 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 genes can change how the body breaks down a drug, moves it through the body, or responds to it at its target. This helps explain why the same medication may work well for one person, do less for another, or cause more side effects in someone who is more sensitive to it.
What is Pharmacogenetics?
Pharmacogenetics is the area of study focused on how genetic differences affect response to medications. It examines relationships between genes and drugs to help explain why treatments do not work the same way for every person. With many medicines, genes can influence how strongly a drug works or how the body handles it. This information can help support treatment decisions that are better informed and more individualized.

Drugs influenced by the KIF25 gene
When should I seek medical advice?
There is not yet a broadly confirmed role for this gene in how people respond to medicines, so questions about side effects, treatment changes, or new symptoms are best discussed with your doctor.
