The KIF24 gene helps cells manage tiny support fibers and control cilia, the small antenna-like structures that help cells sense signals. In medicine, this gene is important because it helps regulate when cilia are built and how cells organize for division. If the KIF24 gene does not work properly, cell signaling and early growth can be disrupted. Rare harmful variants in this gene have been linked to inherited conditions that affect development.
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 code for proteins, the parts of cells that do much of the work. Others mainly guide when certain processes happen, where they happen, and how strongly they run. Together, genes affect how the body develops and works, and they can influence how you respond to food, stress, or medications. To explore this topic in more detail, you can learn more in the LearnHub.
Overview
KIF24Gene function
What if the gene works
The KIF24 gene helps cells control when to build a primary cilium, a tiny antenna on the cell surface. It also supports normal centriole function, which helps cells organize their internal skeleton during cell division.
Risk
What if the gene does not work
When the KIF24 gene works less well, cells may have trouble limiting primary cilia formation and keeping centrosomes working normally. Milder variants may partly reduce this control, while more severe variants can interfere more strongly with cilia regulation and cell division.
Treatment
What does that mean for your treatment
No treatment or drug choice approach tied specifically to pathogenic variants in the KIF24 gene is currently established in clinical guidelines. The KIF24 gene is being studied in cancer research as a possible biomarker and treatment target because changes in its activity may influence cell division and tumor growth.
Gene function
What if the gene works
Your cells use the KIF24 gene to manage tiny internal fibers and control when a cilium, a small cell antenna, should form. It works mainly at the centrosome, the structure that organizes these fibers near the base of a cilium. Understanding how the KIF24 gene helps control cilia makes it easier to see how cells balance sensing their surroundings with preparing to divide.
The KIF24 gene helps decide when a primary cilium, the cell's small sensing antenna, should stay off. This keeps growing or dividing cells focused on their current job instead of building that structure too soon.
Its protein can shorten microtubules, the tiny hollow fibers that form part of the cell's inner framework. This careful trimming near the cilium base helps control whether a cilium starts to grow.
The KIF24 gene works at the centrosome, a cell structure that organizes microtubules. By shaping this area, it supports the normal switch between building a sensing cilium and preparing for cell division.
What is a variant?
A genetic variant is a minor alteration in the DNA sequence within a gene. These changes are common and are part of normal human diversity, including differences in appearance, metabolism, and the way the body responds to environmental influences. Many variants do not have any noticeable effect and simply reflect 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 KIF24 gene can change the shape of its motor protein, reduce its stability, or weaken how it binds to cell scaffolding called microtubules. The effects of KIF24 gene variants on protein function range from mild, with partial activity left, to more severe, where the protein is cut short or broken down before it can work. These changes may also disrupt where the protein sits in the cell and how it interacts with other proteins that organize microtubules.
How variants are linked to conditions
Current evidence does not yet show a broadly confirmed link between variants in the KIF24 gene and a specific health condition, though research on how variants in the KIF24 gene are linked to conditions is still evolving. Anyone with a confirmed KIF24-related finding should rely on guidance from their doctor or genetic counselor for interpretation in the context of their own health and family history.
A variant is not necessarily a diagnosis
Genetic variants are a usual feature of human biology and are widely found in the general population. Most do not directly affect health and instead reflect normal human diversity. For many genes, having 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 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 health risk related to the KIF24 gene. People with concerns about their personal or family risk can talk with a doctor or genetic counselor for guidance based on their own health history.
Inheritance of KIF24 variants
There is not yet a broadly confirmed, disease-specific Mendelian pattern for how variants of the KIF24 gene are inherited, so the answer to how KIF24 gene variants are inherited is still being clarified as research develops. The KIF24 gene is located on chromosome 9, which is an autosome. That means each person usually inherits one copy of the KIF24 gene from their mother and one copy from their father.
What does my KIF24 result mean for my family?
There is not yet a broadly confirmed inheritance pattern tied to a specific condition for KIF24. If you have a KIF24 result and want to understand what it could mean for relatives, a doctor or genetic counselor can help explain it in the context of your family.
Genetic information
Genetic testing
How you find out about variants
Variants in the KIF24 gene are usually found with KIF24 genetic testing as part of a multi gene panel, exome test, or genome test using a blood sample or cheek swab. The lab reads the gene’s DNA code and compares it with the usual sequence to look for variants that may help explain a person’s condition or family history.
When should I consider getting a genetic test?
There isn't yet a broadly established KIF24-specific clinical reason for testing in routine care. Decisions about genetic testing are best made with a doctor or genetic counselor, based on your symptoms, family history, and whether a broader gene panel or exome test is being considered.
A genetic result is only one part of your health story
Genetic results can be informative, but how much they reveal varies based on the condition and the kind of variant involved. Over time, lifestyle, environment, age, and medical history also influence how the body functions. For some conditions, especially those shaped by many genes, genetic information offers context rather than certainty and is best considered alongside other parts of care. In other situations, a genetic result may offer a clear answer. In areas like medication response, genetic findings 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 uses a drug, so the same treatment may work better for one person than another or cause more side effects in some people. This kind of variation is common and is one reason medication response can differ even when people take the same dose.
What is Pharmacogenetics?
Pharmacogenetics examines how differences in genes can affect the way a person responds to medications. By studying links between genes and drugs, it helps explain why the same treatment may work differently in different people. For many medicines, genes influence either how the body handles a drug or how strong its effects are. 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 KIF24 gene
When should I seek medical advice?
There is not yet a broadly confirmed role for this gene in guiding medication choice or dose, so general questions about side effects, new symptoms, or how medicines may affect you are best discussed with your doctor.
