The CDH24 gene gives cells instructions for a protein that helps neighboring cells stick to each other and stay organized, especially in tissues that form protective linings. If this gene does not work properly, cells may not hold together as well, which can affect how tissues are built and maintained. Researchers are also studying whether changes in the CDH24 gene may play a role in some cancers by altering how cells grow, attach, and spread.
What is a gene?
A gene is a stretch of DNA that holds information your cells use to make molecules or manage processes in the body. Some genes carry the instructions for making proteins, the parts of cells that do the work. Others mainly control when certain processes happen, where they happen, and how strongly they occur. Together, genes affect how the body develops and works, and they can shape how you respond to food, stress, or medications.

Overview
CDH24Gene function
What if the gene works
The CDH24 gene helps neighboring cells stick together using calcium. It is active in tissue linings and supports organized cell layers.
Risk
What if the gene does not work
Variants in the CDH24 gene can range from milder to more severe and may reduce how well this cell adhesion protein works, weakening contact between neighboring cells and disrupting how surface tissues stay organized.
Treatment
What does that mean for your treatment
No CDH24-specific treatment, drug choice, or management approach is currently established for pathogenic or loss-of-function variants in the CDH24 gene.
Gene function
What if the gene works
Cells in the body need steady contact with nearby cells to form smooth, organized tissue layers. The CDH24 gene helps provide that contact by making a surface protein that supports cell to cell attachment. Understanding CDH24 gene function helps explain how cells stay attached and arranged in everyday tissue life.
The CDH24 gene makes a cadherin protein that sits on the cell surface and helps neighboring cells hold onto each other. This contact depends on calcium, which helps the protein keep the right shape for binding.
By helping nearby cells connect, CDH24 supports neat, stable cell layers in tissues that line organs and body surfaces. This everyday adhesion can help cells stay in the right place as tissues renew and maintain their structure.
Its protein helps cells recognize and prefer contact with similar neighboring cells. That selective attachment supports orderly tissue organization rather than random mixing.
What is a variant?
A genetic variant is a small difference in the DNA sequence within a gene. These changes are common and are part of normal human diversity, including differences in appearance, metabolism, or the way the body responds to environmental influences. Many variants have no noticeable effect and simply represent natural genetic variation. Sometimes, though, a variant can change how a gene works more significantly and may contribute to or cause a genetic condition.
Genetic variants
What if the gene does not work
Variants in the CDH24 gene can change the CDH24 protein’s shape, stability, or ability to reach the cell surface, which helps explain how CDH24 gene variants affect protein function. Some variants may weaken folding or reduce binding to nearby cell proteins, while more disruptive variants can sharply lower protein levels or stop protein production altogether. This range from milder to more severe variants can lead to partial loss or near complete loss of cellular activity.
How variants are linked to conditions
Current research on how variants of the CDH24 gene are linked to conditions is still developing. The CDH24 gene does not yet have a broadly confirmed link to a specific health condition, so anyone with a confirmed CDH24-related diagnosis should rely on guidance from their doctor or genetic counselor rather than general information.
A variant is not necessarily a diagnosis
Variants in genes are common across the general population and are a normal feature of human biology. Most do not directly affect health and instead reflect natural variation among people. For many genes, having a variant associated with a condition indicates a possible link rather than a confirmed diagnosis, particularly when several genes and environmental influences are involved. In some situations, though, one 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 is not yet broadly confirmed evidence on specific factors that increase or reduce health risk related to the CDH24 gene. Anyone with concerns about personal or family risk can talk with a doctor or genetic counselor.
Inheritance of CDH24 variants
There is not yet a broadly confirmed, disease-specific Mendelian inheritance pattern for the CDH24 gene, so how CDH24 gene variants are inherited in relation to health conditions is still being clarified. The CDH24 gene is located on chromosome 14, which is an autosome, so each person inherits one copy from each parent.
What does my CDH24 result mean for my family?
There is not yet a broadly confirmed inherited condition linked to the CDH24 gene in the way there is for some other genes. If you have a specific CDH24 result and want to understand what it could mean for relatives, a doctor or genetic counselor can help interpret it in the context of your family history and the exact change found.
Genetic information
Genetic testing
How you find out about variants
To look for changes in the CDH24 gene, a lab analyzes DNA from blood, saliva, or a cheek swab. CDH24 genetic testing reads the gene’s sequence and compares it with a reference to identify variants, then a specialist classifies the result as benign, uncertain, or linked to disease when supported by evidence.
When should I consider getting a genetic test?
There isn't yet a broadly established CDH24-specific clinical reason for testing. Decisions about genetic testing are usually based on your personal health history, family history, and the findings your doctor or genetic counselor is trying to explain.
A genetic result is only one part of your health story
A genetic result can be informative, but how much it reveals depends on the condition and the type of variant involved. Many factors, including lifestyle, environment, age, and medical history, 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 such as 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 your body handles medicines, so the same treatment may work differently from one person to another. Some people break down a drug faster or slower, while others are more or less sensitive to its effects. This common difference can shape how well a medication works and how likely side effects are.
What is Pharmacogenetics?
Pharmacogenetics examines how genetic differences affect the way people respond to medications. It studies relationships between genes and drugs to better understand why the same treatment can work differently from one person to another. For many medicines, genes influence both how strongly a drug works and how the body processes it. This information can help support more informed and individualized treatment decisions. More detail on this topic is available in the LearnHub.
Drugs influenced by the CDH24 gene
When should I seek medical advice?
There is not yet a broadly confirmed role for this gene in guiding medicine choice or dose. If you have unusual side effects, a medicine is not working as expected, or you have general questions about treatment, it is best to discuss this with your doctor.
