The CD93 gene helps cells lining your blood vessels stick, grow, and organize normally, and it also supports parts of the immune system as they clear away damaged material. If it does not work properly, blood vessel growth and tissue repair may be less well coordinated, and inflammation may be harder to regulate. What this gene does can influence how your body responds to injury and some long term conditions. The CD93 gene is mainly known in medical research rather than popular culture.
What is a gene?
Within your DNA, a gene is a stretch that carries information cells can use to make molecules or direct processes in the body. Some genes contain instructions for making proteins, the functional parts of cells. Other genes mainly help control when certain processes run, where they run, and how strongly they run. Together, genes influence how the body develops and functions, and they can shape how you respond to food, stress, or medications.

Overview
CD93Gene function
What if the gene works
The CD93 gene helps cells lining blood vessels attach, move, and form stable vessels. It also supports immune system signaling and the clearance of dying cells.
Risk
What if the gene does not work
Changes in the CD93 gene can reduce how well cells stick, migrate, and clear debris, especially in blood vessel lining. Milder variants may partly weaken CD93 signaling, while more severe variants can disrupt vessel growth and immune cell interactions.
Treatment
What does that mean for your treatment
At present, no treatment or drug choice strategy is specifically established for pathogenic or loss-of-function variants in the CD93 gene. CD93 is being studied mainly as a biomarker and possible drug target in some cancers and inflammatory conditions, but this has not changed routine treatment decisions.
Gene function
What if the gene works
Your body uses the CD93 gene most in cells that line blood vessels and in some immune cells. Its protein sits on the cell surface, where it helps cells attach, move in a controlled way, and respond to nearby support tissue. A key part of CD93 gene function in blood vessels is keeping this lining organized during normal tissue upkeep.
The CD93 gene helps cells on blood vessel walls attach to the supportive material around them. This steady contact helps cells keep their shape and stay where they belong.
Its protein supports the careful movement and spreading of vessel lining cells. This makes it easier for cells to shift into place during normal growth, renewal, and repair.
The CD93 gene supports the orderly steps cells use to form and organize small blood vessels. This helps the vessel lining grow as a smooth, connected layer.
Its protein helps cells sense and respond to cues from nearby support tissue. This coordination links attachment with movement so the vessel lining stays well organized.
What is a variant?
A genetic variant is a small difference in the DNA sequence of a gene. These changes are common and help shape normal human diversity, 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 cases, though, a variant can change how a gene functions more substantially and may contribute to or cause a genetic condition.
Genetic variants
What if the gene does not work
Variants in the CD93 gene may change the shape of the CD93 protein, reduce how much reaches the cell surface, or weaken its contact with partner molecules. This is how variants in the CD93 gene affect protein function at the cellular level. Milder variants may partly reduce protein stability or surface activity, while more severe variants can greatly lower protein production or create a shortened protein that is broken down quickly.
How variants are linked to conditions
CD93 does not yet have a broadly confirmed link to a specific health condition, though research on CD93 gene variants and disease risk is still developing. If you carry a variant in the CD93 gene, the meaning of that result is best understood alongside your personal health picture and family history.
A variant is not necessarily a diagnosis
Genetic variants are a usual part of human biology and are widespread in the general population. Most do not have a direct effect on health and instead reflect natural human variation. For many genes, carrying a variant associated with a condition indicates a possible link rather than a definite diagnosis, especially when multiple genes and environmental factors also 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 CD93 gene. If a CD93 result is part of your medical care, a doctor or genetic counselor can help put it in the context of your personal and family history.
Inheritance of CD93 variants
There is not yet a broadly confirmed, disease-specific Mendelian pattern for inheritance of the CD93 gene variants in routine human genetics. Research has linked the CD93 gene to some health traits and disease risk, but these findings do not establish a single clear pattern such as autosomal dominant or autosomal recessive inheritance. The CD93 gene is located on chromosome 20, which is an autosome, so each person inherits one copy from each parent. In that general sense, changes in the CD93 gene can be passed down through either side of the family.
What does my CD93 result mean for my family?
There is not yet a broadly confirmed inherited pattern tying CD93 changes to a specific well-recognized genetic condition in families, though this can become clearer as research grows. If you have a specific CD93 result and want to understand what it could mean for close relatives, a doctor or genetic counselor can help interpret it in the context of your family history.
Genetic information
Genetic testing
How you find out about variants
To look for changes in the CD93 gene, doctors use genetic testing on a blood or saliva sample. In CD93 genetic testing, a lab reads the DNA code and compares it with the usual sequence to spot variants. Results may show a benign variant, a variant of uncertain significance, or a variant linked to disease.
When should I consider getting a genetic test?
There is not yet a broadly established CD93-specific clinical reason for genetic testing. Decisions about testing 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 the kind of variant involved. Many factors, including lifestyle, environment, age, and medical history, shape how the body works over time. For some conditions, especially those influenced by many genes, genetic information adds context rather than certainty and is best understood together with other aspects of care. In other situations, a genetic result can offer a clear answer. In areas like 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 people respond to medicines. Small differences in genes can change how the body breaks down a drug, moves it through the body, or reacts to it at its target. Because of this, the same medication may help one person more than another, or may make one person more sensitive to side effects. This is common and is only one part of the picture, alongside factors such as age, liver and kidney function, and other medicines.
What is Pharmacogenetics?
Pharmacogenetics examines how differences in a person’s genes affect the way they respond to medications. By looking at links between genes and drugs, it helps explain why the same treatment can work differently in different people. For many medicines, genes can influence how strongly a drug works or how the body handles it. This information can support treatment decisions that are more informed and more individualized. More detailed information on this topic is available in the LearnHub.
Drugs influenced by the CD93 gene
When should I seek medical advice?
There is not yet a broadly confirmed role for this gene in guiding medication choices. If you have questions about side effects, how well a treatment is working, or concerns about your medicines, talk with your doctor.
