The CD164 gene helps make a protein on the surface of cells that supports how they stick, move, and interact with their surroundings. This gene plays an important role in guiding blood-forming stem cells in the bone marrow, where new blood cells are made. If the CD164 gene does not work properly, these cell movements and signals may be less controlled, which can affect normal tissue function. CD164 is mainly discussed in research and clinical genetics rather than in popular culture.
What is a gene?
Genes are stretches of DNA that carry instructions cells use to make molecules or regulate activities in the body. Some genes provide the code for proteins, which do much of the cell’s work. Others mostly guide when specific processes happen, where they happen, and how active they are. Taken together, genes affect how the body grows and works, and they can influence how you respond to food, stress, or medicines. For a closer look at this subject, more information is available in LearnHub.
Overview
CD164Gene function
What if the gene works
The CD164 gene helps cells stick, move, and communicate with their surroundings. It is especially active in blood-forming cells and supports how some stem cells grow and travel within the bone marrow.
Risk
What if the gene does not work
Variants in the CD164 gene can range from milder to more disruptive and may reduce how well cells stick, move, and respond to growth signals. This can alter blood stem cell behavior and cell trafficking.
Treatment
What does that mean for your treatment
No CD164-specific treatment or drug-selection approach is currently established for pathogenic variants in the CD164 gene. In research, the CD164 gene is being studied as a possible biomarker and drug target in some cancers because it may influence how cancer cells grow and spread.
Conditions associated with CD164
Gene function
What if the gene works
Cells use the CD164 gene to control how they attach, move, and settle into the right place. This matters most for blood stem cell movement in the bone marrow. The protein from this gene sits mainly on the cell surface and also passes through internal cell compartments.
The CD164 gene helps cells hold onto nearby cells and their surrounding support material. This steady contact helps cells keep their place within tissues.
It helps guide how certain cells travel, especially blood-forming stem cells moving through the bone marrow. This supports normal homing, meaning cells settle in the tissue where they belong.
The protein made from the CD164 gene helps cells respond to local signals that tell them when to stay put or move. This supports orderly cell behavior during routine tissue upkeep.
What is a variant?
A genetic variant is a small change in a gene’s DNA sequence. These changes are common and help shape normal differences between people, such as appearance, metabolism, or the way the body responds to environmental factors. Many do not have any noticeable effect and are simply part of natural genetic variation. Sometimes, though, a variant changes 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 CD164 gene can change the protein’s shape, stability, or movement inside the cell, so CD164 gene variants may reduce how well it reaches the right membrane compartments or binds to partner molecules. Some changes are milder and leave partial function, while more disruptive variants can lead to a shortened protein or much lower protein levels. This spectrum of effect can influence how strongly cell adhesion, signaling, and intracellular trafficking are altered.
How variants are linked to conditions
CD164 does not yet have a broadly confirmed link to a specific health condition, though this can change as research develops. Current evidence does not support a clear, widely accepted pattern of CD164 gene variants and disease for general patient education, so personal results are best interpreted with a doctor or genetic counselor.
A variant is not necessarily a diagnosis
Genetic variants are a common and normal part of human biology across the general population. Most of them do not have a direct effect on health and simply contribute to natural human diversity. For many genes, having a variant associated with a condition suggests a possible link rather than a confirmed diagnosis, especially when several genes and environmental factors are involved. In some situations, though, one well-characterized variant in a particular 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 CD164 gene. If a CD164 change has been found in your family, a doctor or genetic counselor can help explain what it may mean for your personal risk.
Inheritance of CD164 variants
For families looking into how variants of the CD164 gene are inherited, the best-established pattern is autosomal dominant. This means a person with a disease-causing variant in one copy of the CD164 gene can pass it to a child, and each pregnancy carries a 50% chance of inheriting that variant. The variant can be passed from a mother or father to a son or daughter with the same likelihood. Not everyone who inherits a CD164 gene variant will be affected in exactly the same way.
What does my CD164 result mean for my family?
For CD164, the best-established family pattern is a dominant one linked to an inherited form of hearing loss. This usually means close relatives such as a parent, brother, sister, or child may also carry the same gene change and could have hearing loss or be at risk for it. Family members can be affected to different degrees, so some may notice milder hearing changes than others.
Genetic information
Genetic testing
How you find out about variants
Genetic testing for CD164 variants uses a blood, saliva, or cheek swab sample to read the DNA in the CD164 gene. It is often part of a test that checks many genes at once, and results may show a benign variant, an uncertain finding, or a variant linked to a genetic condition.
When should I consider getting a genetic test?
There is not yet a broadly established, CD164-specific reason to get genetic testing in routine care. Testing decisions 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
Genetic findings can be informative, but how much they reveal depends on the condition and on the type of variant involved. Over time, how the body works is shaped by many factors, including lifestyle, environment, age, and medical history. For some conditions, especially those influenced by many genes, genetic information offers context rather than certainty and is best understood together with other parts of care. In other situations, a genetic result may give a clear answer. In areas like 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 your body responds to medicines. Small differences in genes can change how a drug is absorbed, broken down, moved through the body, or how strongly it acts on its target, so the same treatment may work well for one person but cause more side effects or less benefit in another. This kind of variation is common and is one reason medication response can differ from person to person.
What is Pharmacogenetics?
Pharmacogenetics examines how genetic differences affect the way a person responds to medication. It looks for links between genes and drugs to help explain why the same treatment can work differently from one person to another. With many medicines, genes influence both how strongly a drug works and how the body handles it. This information can support treatment decisions that are better informed and more individualized.

Drugs influenced by the CD164 gene
When should I seek medical advice?
There is not a broadly confirmed role for this gene in guiding medication choices at this time, so concerns about side effects, how well a treatment is working, or changes to your medicines are best discussed with your doctor.
