The STK24 gene gives cells instructions for making a signaling protein that helps control cell shape, movement, growth, and survival. The protein made by this gene helps your cells respond in an organized way when tissues are developing or repairing themselves. If the STK24 gene does not work normally, these signals can become less controlled, which may affect how cells function, including in the brain. The STK24 gene is mainly known in research settings and has not become widely recognized outside medicine.
What is a gene?
Genes are stretches of DNA that carry instructions your cells use to make molecules or direct processes in the body. Some genes provide the instructions for making proteins, the parts of cells that do much of the work. Others mainly regulate when certain processes happen, where they happen, and how active they are. Together, genes affect how the body develops and works, and they can also influence how you respond to food, stress, and medications.

Overview
STK24Gene function
What if the gene works
The STK24 gene gives cells instructions for a signaling protein that helps control growth, shape, and movement. It also supports how cells organize their internal skeleton and respond to everyday signals.
Risk
What if the gene does not work
Changes in the STK24 gene can reduce or alter signaling that helps cells organize their internal skeleton, move, and maintain contacts. Milder variants may have small effects, while more severe variants can more strongly disrupt these cell control pathways.
Treatment
What does that mean for your treatment
At present, no treatment or drug choice is guided specifically by a pathogenic or loss-of-function variant in the STK24 gene, so management depends on the person’s symptoms and overall clinical diagnosis.
Gene function
What if the gene works
Cells use the STK24 gene to coordinate shape, movement, and internal organization. It makes a protein kinase, a protein that adds phosphate tags to other proteins so cell signals can be passed along. This is part of how the STK24 gene works in cells from day to day.
Its protein passes signals by adding phosphate tags to selected proteins. This lets cells adjust routine jobs at the right time and in the right place.
The STK24 gene helps organize the actin cytoskeleton, the cell's internal framework. This supports cell polarity, so a cell can keep a clear front and back and hold its shape.
By guiding the inner framework and polarity, this gene supports steady, directed cell movement. Cells use that control when they spread, reposition, and interact with nearby tissue.
Its protein also helps organize the Golgi apparatus, the cell's packaging and shipping center. This supports normal sorting and delivery of proteins within the cell.
What is a variant?
A genetic variant is a minor difference in the DNA sequence within a gene. These differences are common and are part of normal human diversity, including variation in appearance, metabolism, and the way the body responds to environmental influences. Many variants do not have any noticeable effect and simply represent natural genetic variation. Sometimes, though, a variant changes how a gene works to a greater extent and may contribute to, or directly cause, a genetic condition.
Genetic variants
What if the gene does not work
Changes in the STK24 gene can alter the shape or amount of its protein, which may weaken its activity or make it less stable inside cells. This is how variants influence the STK24 gene's function at a molecular level. Some variants may only partly reduce activity, while more severe variants can greatly disrupt the protein or stop it from being made, leading to stronger effects on cell signaling and protein interactions.
How variants are linked to conditions
Current evidence does not yet show a broadly confirmed link between STK24 gene variants and a specific health condition, although research on the STK24 gene and disease risk continues to evolve. If you have a reported variant in the STK24 gene, your doctor or genetic counselor can explain what that result means for you and your family.
A variant is not necessarily a diagnosis
Genetic variants are common in the general population and are a normal feature of human biology. Most do not have a direct effect on health and instead are part of natural 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 factors play a role. In some situations, though, a single well-characterized variant in a particular gene can be 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 STK24 gene. If a test finds a change in STK24, its meaning depends on the exact change and the person’s overall health and family history.
Inheritance of STK24 variants
There is not yet a broadly confirmed disease inheritance pattern for the STK24 gene, so how STK24 gene variants are inherited in relation to a specific medical condition is still being worked out. STK24 is located on chromosome 13, which is an autosome, so each person inherits one copy of the STK24 gene from their mother and one from their father. This means any STK24 variant can be passed down through either side of the family.
What does my STK24 result mean for my family?
There isn't yet a broadly confirmed inheritance pattern tied to a specific condition for STK24, though this understanding can change as research develops. If you have a specific STK24 result and questions about what it could mean for your family, a doctor or genetic counselor can explain it in the context of your personal and family history.
Genetic information
Genetic testing
How you find out about variants
STK24 genetic testing usually reads the STK24 gene from a blood or saliva sample to look for DNA variants. It is often done as part of a multigene panel or broader sequencing test. Results may show a benign change, a variant of uncertain significance, or a variant that helps explain a person’s health findings.
When should I consider getting a genetic test?
There is not yet a broadly established, STK24-specific reason for genetic testing in routine care. Testing decisions are usually based on your personal health history, family history, and whether a doctor or genetic counselor thinks a broader gene panel could be helpful.
A genetic result is only one part of your health story
A genetic finding can provide useful insight, but how much it explains varies based on the condition and the type of variant present. Many factors, including lifestyle, environment, age, and medical history, influence how the body functions over time. For some conditions, especially those shaped 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, genetic results can also help put individual experiences into perspective.
Pharmacogenetics
How variants shape your response to medicine
Genetic variation can affect how people respond to medicines. This helps explain why the same treatment may work well for one person, seem weaker for another, or cause more side effects in someone else. Part of the difference comes from how each body absorbs, breaks down, and clears a drug, which can change how much medicine reaches the bloodstream and tissues. These differences are common and can influence both how well a treatment works and how sensitive a person is to it.
What is Pharmacogenetics?
Pharmacogenetics examines how inherited genetic differences can affect a person’s response to medicines. It studies gene-drug patterns to help explain why the same treatment may work differently in different people. For many drugs, genes can influence how much effect a medicine has or how the body handles it. This information can support more informed, more personalized treatment choices. More detail on this topic is available in the LearnHub.
Drugs influenced by the STK24 gene
When should I seek medical advice?
There is not yet a broadly confirmed role for this gene in guiding medication choices. Questions about side effects, how well a treatment is working, or possible drug interactions are best discussed with your doctor.
History
STK24 came into the scientific literature in the late 1990s, during a period when researchers were identifying many new protein kinases, a group of genes involved in cell signaling. It was first described under the name MST3, and later naming systems aligned it with the STK24 gene. As medical science evolved, scientists placed it within the germinal center kinase III family, which helped organize related genes more clearly. From these first observations, research expanded steadily, and STK24 became part of broader efforts to map how cells coordinate growth, structure, and internal signaling.
