The CD248 gene helps support cells around blood vessels grow, attach, and communicate during tissue repair. If it does not work normally, these support cells may not behave as expected, which can affect healing and the way tissue is built around small blood vessels. This gene is closely observed in clinical research due to its role in scar forming tissue and in the tissue that surrounds some tumors. CD248 is not a gene that is widely known in everyday public discussions.
What is a gene?
Genes are stretches of DNA that give cells instructions for making molecules or guiding activities in the body. Some genes provide the directions to make proteins, which do much of the cell’s work. Others mainly regulate when a process happens, where it happens, and how active it is. In combination, genes affect how the body develops and works, and they can also influence how you respond to food, stress, or medications.

Overview
CD248Gene function
What if the gene works
The CD248 gene helps make a cell surface protein found mainly on support cells around blood vessels. It helps these cells attach and move, which supports blood vessel growth and tissue repair.
Risk
What if the gene does not work
Milder to more severe variants in the CD248 gene can partly reduce or more fully disrupt this surface protein, altering how support cells bind, move, and respond to signals in connective tissue and blood vessel walls.
Treatment
What does that mean for your treatment
No CD248-specific treatment or management approach is currently established for pathogenic or loss-of-function variants in the CD248 gene. CD248 is being studied as a biomarker and possible drug target, especially in cancer tissue and fibrotic conditions.
Gene function
What if the gene works
This gene is most active in support cells that sit around blood vessels and within connective tissue. It helps these cells connect with their surroundings, keep tissues organized, and take part in normal growth and renewal. Understanding the CD248 gene’s function helps you see how your body maintains structure across different tissues.
The CD248 gene makes a surface protein that helps support cells attach to proteins around them. This lets cells sense their surroundings and stay positioned within connective tissue.
This protein helps connective tissue cells spread and arrange themselves in an orderly way. By doing so, it supports normal tissue growth, renewal, and everyday structural support.
Around small blood vessels, CD248 helps nearby support cells interact with the vessel wall. These contacts help blood vessels stay stable as tissues receive oxygen and nutrients.
The CD248 gene also helps cells respond to signals from their local environment. A simple way to understand what the CD248 gene does is that it supports controlled cell movement and communication during routine tissue remodeling.
What is a variant?
A genetic variant is a slight difference in the DNA sequence within a gene. These differences are common and help shape normal human diversity, including variation in appearance, metabolism, and the way the body responds to environmental influences. Many variants do not lead to any noticeable effect and are simply part of natural genetic variation. Sometimes, though, a variant changes how a gene works more substantially and can contribute to or cause a genetic condition.
Genetic variants
What if the gene does not work
CD248 gene variants can change the protein's shape, stability, or ability to reach the cell surface. When describing how CD248 gene variants affect protein function, the main differences are whether a variant slightly weakens folding or interactions, or more severely shortens the protein or stops it from being made. Milder variants may leave some protein activity, while more disruptive variants can greatly reduce or abolish protein production.
How variants are linked to conditions
Current research on how CD248 gene variants are linked to conditions has not yet established a broadly confirmed connection to a specific health problem. This picture can change as research develops, so anyone with a confirmed finding in the CD248 gene should use advice from their doctor or genetic counselor to understand what it may mean personally.
A variant is not necessarily a diagnosis
Gene variants are common in the general population and are a normal part of human biology. Most do not have a direct effect on health and instead reflect the natural range of human diversity. For many genes, carrying a variant associated with a condition suggests a possible link rather than a confirmed 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 isn't yet broadly confirmed evidence on specific factors that increase or reduce health risk related to the CD248 gene. Anyone with concerns about their personal risk or test results can speak with a doctor or genetic counselor.
Inheritance of CD248 variants
There is not yet a broadly confirmed disease specific inheritance pattern for the CD248 gene, so CD248 gene inheritance is not described as a standard autosomal dominant or autosomal recessive condition at this time. The CD248 gene is located on chromosome 11, which is an autosome, so you inherit one copy from each parent. In general, that means any change in this gene could be passed through either side of the family.
What does my CD248 result mean for my family?
There is not yet a broadly confirmed inheritance pattern tied to a specific health condition for CD248, and this may become clearer as research grows. If you have a specific CD248 result and want to understand what it could mean for relatives, a doctor or genetic counselor can help explain it in the context of your family history and health.
Genetic information
Genetic testing
How you find out about variants
To look for changes in the CD248 gene, testing uses a blood sample, saliva, or cheek swab. Genetic testing for CD248 variants reads your DNA and may be done as part of a multigene panel rather than on its own. Results show whether a variant was found and how clearly it can be interpreted.
When should I consider getting a genetic test?
There isn't yet a broadly established, CD248-specific clinical reason for genetic testing. Decisions about testing are best made with a doctor or genetic counselor, based on your symptoms, medical history, and family history.
A genetic result is only one part of your health story
A genetic finding can be informative, but what it can tell you varies with the condition and the kind of variant involved. Lifestyle, environment, age, and medical history, among other factors, all influence how the body functions over time. In some conditions, particularly those shaped by many genes, genetic information offers context rather than certainty and is best understood alongside other parts of care. In other situations, a genetic result can give a clear answer. In areas such as medication response, genetic results may help put individual experiences in context.
Pharmacogenetics
How variants shape your response to medicine
Genetic variation can affect how people respond to medicines. Small differences in genes can change how the body breaks down a drug, moves it through the body, 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 some people.
What is Pharmacogenetics?
Pharmacogenetics examines how genetic differences can shape a person’s response to medications. By studying links between genes and drugs, it helps explain why the same treatment may work differently from one person to another. For many medicines, genes affect how strongly a drug works or how the body processes it. This information can support more informed, more individualized treatment decisions.

Drugs influenced by the CD248 gene
When should I seek medical advice?
There is not yet a broadly confirmed role for this gene in guiding medication response. Questions about medicines, side effects, or treatment changes are best discussed with your doctor.
History
CD248 came into view in the late 1990s during efforts to map markers on tumor blood vessels and nearby support tissue. It was described under different names, including endosialin and tumor endothelial marker 1, before researchers recognized they were studying the same protein and the name CD248 became standard. Initially understood only through visible tissue patterns, later recognized as tied to a specific gene, it drew interest because it seemed more active in certain cancers than in most healthy adult tissues. From these first observations, research expanded steadily into cancer biology, tissue repair, and fibrosis. The way this gene was viewed has shifted over time, with later studies showing that its role extends beyond blood vessel lining cells alone.
