The ADGRE3 gene works mainly in certain white blood cells, where it helps cells sense nearby signals and move to areas of inflammation or infection. This gene helps your body coordinate parts of the immune response, especially when tissues are irritated or under stress. If the ADGRE3 gene does not work as expected, immune cell communication and movement may be altered, which may affect how inflammation is handled. For most people, this gene is not a well known part of public health discussions, but it matters in research on immune function.
What is a gene?
Genes are stretches of DNA that hold instructions your cells use to make molecules or regulate processes in the body. Some genes carry the code for proteins, which do much of the cell’s work. Others mainly help direct 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.

Overview
ADGRE3Gene function
What if the gene works
The ADGRE3 gene helps make a surface receptor used mainly by certain immune cells. It supports how these cells sense signals and interact with other cells.
Risk
What if the gene does not work
Variants in the ADGRE3 gene may alter signaling at the cell surface, especially in certain immune cells. Milder variants can partly change receptor activity, while more severe variants may greatly reduce how cells sense and respond to nearby signals.
Treatment
What does that mean for your treatment
No treatment or management approach tied to pathogenic variants in the ADGRE3 gene is currently established. The ADGRE3 gene is being studied as an immune related biomarker in some cancers, but this has not led to guideline based drug choices.
Gene function
What if the gene works
In your immune system, the ADGRE3 gene helps certain white blood cells receive and pass along signals from their surroundings. It is most active in cells such as monocytes and granulocytes, which help the body respond to irritation, tissue changes, and infection. Knowing what the ADGRE3 gene does in immune cells can make genetic results easier to place in context.
This gene makes a receptor that sits on the surface of some white blood cells. It helps those cells notice nearby signals and changes in their environment.
When that receptor is engaged, it relays messages into the cell through G proteins (signal-carrying switches inside cells). These messages help tune the cell's activity to what is happening around it.
As part of the adhesion receptor family, it also supports contact between immune cells and nearby tissues. This can help white blood cells position themselves and respond in a more coordinated way.
What is a variant?
A genetic variant is a minor change 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 cause any noticeable effects and simply represent natural genetic variation. In some situations, 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 ADGRE3 gene can change how the receptor is built, cut into its working parts, or placed on the cell surface. In plain terms, how ADGRE3 gene variants affect protein function often comes down to altered folding, weaker stability, or less reliable signaling between immune cells. Milder variants may slightly reduce receptor activity, while more disruptive variants can greatly lower cell surface expression or signaling output.
How variants are linked to conditions
The ADGRE3 gene does not yet have a broadly confirmed link to a specific health condition, so information on ADGRE3 gene variants and health conditions is still evolving. If you have a confirmed variant in the ADGRE3 gene as part of a personal diagnosis, your doctor or genetic counselor can explain what it may mean in the context of your own medical history and family background.
A variant is not necessarily a diagnosis
Variants in genes are a routine feature of human biology and are widespread across the general population. Most do not directly affect health and simply reflect natural differences among people. For many genes, having a variant tied to a condition suggests a possible link rather than a confirmed diagnosis, particularly when several genes and environmental influences play a role. In some situations, though, one well understood variant in a particular gene is enough to establish 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 ADGRE3 gene. Anyone with concerns about personal or family risk can talk with a doctor or genetic counselor about what this result may mean in their situation.
Inheritance of ADGRE3 variants
For people looking into how variants of the ADGRE3 gene are inherited, there is not yet a broadly confirmed disease specific inheritance pattern for the ADGRE3 gene in human genetics. This may become clearer as research develops and as more families are studied. The ADGRE3 gene is located on chromosome 19, which is an autosome, so each person inherits one copy from each parent.
What does my ADGRE3 result mean for my family?
There is not yet a broadly confirmed inheritance pattern tied to a specific health condition for ADGRE3, and research on this gene is still developing. If you have a specific ADGRE3 result and want to understand what it could mean for close relatives, a doctor or genetic counselor can help put it in the right family context.
Genetic information
Genetic testing
How you find out about variants
Genetic testing for ADGRE3 variants uses a blood or saliva sample to read the DNA in the ADGRE3 gene. The lab looks for changes in the gene sequence and compares them with known findings. Results may identify a benign variant, a disease linked variant, or a variant of uncertain significance.
When should I consider getting a genetic test?
There is not yet a broadly established ADGRE3-specific clinical reason for testing. Decisions about genetic testing are best made with a doctor or genetic counselor, based on your health history and family history.
A genetic result is only one part of your health story
A genetic result can provide useful insight, but the amount it reveals varies with the condition and the kind of variant found. How the body functions over time is also shaped by many other factors, including lifestyle, environment, age, and medical history. For some conditions, particularly those affected 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 give a clear answer. In areas like medication response, genetic findings can help put a person’s 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 breaks down a drug, moves it through the bloodstream, or responds to it at its target. This helps explain why the same treatment works well for one person, works less well for another, or causes more side effects in someone who is more sensitive to it.
What is Pharmacogenetics?
Pharmacogenetics examines how genetic differences can shape a person’s response to medications. It studies links between genes and drugs to help explain why the same treatment may work differently from one person to another. For many medicines, genes can affect both how strongly a drug works and how the body processes it. This information can support more informed and more individualized treatment decisions. More detailed information on this topic is available in the LearnHub.
Drugs influenced by the ADGRE3 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 medicines or side effects are best discussed with your doctor. Research on the ADGRE3 gene has looked at how it may affect immune cell behavior, but it is not currently used in routine prescribing decisions.
