The CCL23 gene gives your body instructions for making a small immune signaling protein that helps guide white blood cells to places where they are needed, especially during inflammation. If this gene does not work as expected, immune cells may be called in less effectively or at the wrong time, which can influence how the body handles inflammation. Many variants in this gene have little effect, while some are being studied for links to inflammatory and blood related conditions.
What is a gene?
Genes are sections of DNA that hold instructions your cells use to make molecules or manage processes in the body. Some genes provide the directions for building proteins, which are the parts of cells that do the work. Others are mainly involved in regulating when certain processes happen, where they happen, and how active they are. Taken together, genes affect how the body grows and works, and they can also influence how you respond to food, stress, or medicines. For a deeper look at this topic, more information is available in the LearnHub.
Overview
CCL23Gene function
What if the gene works
The CCL23 gene helps immune cells communicate and move to places where the body needs a response. Its protein mainly attracts certain white blood cells and supports controlled inflammation.
Risk
What if the gene does not work
Changes in the CCL23 gene can reduce or alter a signaling protein that helps guide certain immune cells. Milder variants may slightly change this chemical signal, while more severe variants can greatly limit how immune cells move and communicate.
Treatment
What does that mean for your treatment
No CCL23-specific treatment or management approach is currently established in clinical guidelines. The CCL23 gene is being studied mainly as a marker of inflammation and in some cancers, rather than as a guide to choosing approved medicines.
Gene function
What if the gene works
Your immune system uses the CCL23 gene to send location signals to certain white blood cells. Its protein is a chemokine, a small messenger that helps immune cells move toward tissues that need attention. This helps explain what the CCL23 gene does in the immune system during routine immune surveillance and inflammation.
The CCL23 gene helps make a chemokine, a small protein signal used by the immune system. Cells release this signal to communicate that a tissue needs immune attention.
This protein can attach to CCR1, a docking receptor on certain white blood cells. That signal helps monocytes and some T cells move toward the right tissue location.
By drawing selected immune cells into the same area, it helps organize a focused immune response. This supports everyday immune surveillance and a more coordinated reaction to tissue stress.
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 variation, including differences in appearance, metabolism, and how the body responds to environmental influences. Many variants do not cause any noticeable effect and simply represent natural genetic variation. In some situations, though, a variant can change how a gene functions more significantly and may contribute to or cause a genetic condition.
Genetic variants
What if the gene does not work
Variants in the CCL23 gene can change how much of its immune signaling protein is made, how stable it is, and how well it is released from the cell or binds its receptor (cell surface docking site). This is how CCL23 gene variants affect protein function at a cellular level. Milder variants may slightly reduce signaling, while more severe variants can markedly lower protein production or create a shortened protein that is cleared quickly or cannot interact normally.
How variants are linked to conditions
Current evidence on how variants of the CCL23 gene are linked to conditions is still developing, and the CCL23 gene does not yet have a broadly confirmed link to one specific health condition. If you have a confirmed change in the CCL23 gene, your doctor or genetic counselor can explain what it may mean in the context of your personal and family health history.
A variant is not necessarily a diagnosis
Genetic variants are a routine part of human biology and are widespread in the general population. Most do not have a direct effect on health and simply reflect natural human diversity. For many genes, carrying a variant associated with a condition indicates 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 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 CCL23 gene. CCL23 has been studied in immune signaling and in links with some diseases, but these findings do not translate into clear, personal risk factors. Anyone concerned about their own risk can talk with a doctor or genetic counselor.
Inheritance of CCL23 variants
For people looking into how CCL23 gene variants are inherited, there is not yet a broadly confirmed, condition-specific Mendelian inheritance pattern for the CCL23 gene. As research develops, this picture may become clearer. The CCL23 gene is located on chromosome 17, which is an autosome, so each person inherits one copy from each parent. That means any CCL23 variant present in a family can be passed through either the mother or the father.
What does my CCL23 result mean for my family?
There is not yet a broadly confirmed inherited condition linked specifically to the CCL23 gene in the way seen with some better-known genes. If you have a CCL23 result and want to understand what it could mean for relatives, the meaning usually depends on the exact finding and the health concern being evaluated.
Genetic information
Genetic testing
How you find out about variants
To find out whether you carry a variant in the CCL23 gene, a lab can do genetic testing for CCL23 gene variants on a blood or saliva sample. The test reads your DNA and compares the CCL23 gene with a reference sequence to identify variants, which are then classified using standard lab guidelines.
When should I consider getting a genetic test?
There is not yet a broadly established reason to get genetic testing just for the CCL23 gene. Testing choices are usually based on your personal health and family history and are best discussed with a doctor or genetic counselor.
A genetic result is only one part of your health story
A genetic finding can provide useful insight, but how much it explains depends on the condition and on the type of variant involved. Many other factors, including lifestyle, environment, age, and medical history, also shape how the body works over time. For some conditions, especially those influenced by many genes, genetic information provides context rather than certainty and is best understood alongside other parts of care. In other situations, a genetic result can offer a clear answer. In areas like medication response, genetic information can help make sense of individual experiences.
Pharmacogenetics
How variants shape your response to medicine
Genetic variation can affect how people respond to medicines. Two people taking the same medication may not have the same results because their bodies can absorb, break down, or respond to that drug differently. These inherited differences are common and can influence how well a treatment works or how sensitive someone is to side effects. Medication response also depends on other factors, including age, liver and kidney function, and other medicines being taken.
What is Pharmacogenetics?
Pharmacogenetics examines how genetic differences can affect the way a person responds to medications. It studies connections between genes and drugs to help explain why the same treatment may work differently from one person to another. With many medicines, genes can influence both how strongly a drug works and how the body processes it. This information can help support treatment decisions that are more informed and individualized. More detailed information on this topic is available in the LearnHub.
Drugs influenced by the CCL23 gene
When should I seek medical advice?
There is not yet a broadly confirmed role for this gene in predicting how medicines will work or what side effects they may cause, so general health concerns and any questions about medications are best discussed with your doctor or pharmacist.
