The CLEC14A gene helps the cells that line blood vessels attach to each other and guide the growth of new blood vessels. If it does not work properly, blood vessel formation and repair may be less organized, which can affect how tissues receive oxygen and nutrients. This gene plays an important role in research on tumor blood vessels and other conditions where new vessel growth matters, although it is not a gene most people hear about outside medical studies.
What is a gene?
A gene is a stretch of DNA that gives your cells instructions they can use to make molecules or regulate processes in the body. Some genes carry the directions for producing proteins, which are the working parts of cells. Others mainly help control when and where certain processes happen, and how strongly they run. Together, genes affect how the body develops and functions, and they can influence how you respond to food, stress, and medications. For a more in depth look at this topic, you can learn more in the LearnHub.
Overview
CLEC14AGene function
What if the gene works
The CLEC14A gene helps cells lining blood vessels stick to nearby tissues and to each other. This supports healthy blood vessel growth and repair, especially when your body needs to make new vessels.
Risk
What if the gene does not work
Reduced activity of the CLEC14A gene can disturb how endothelial cells stick, move, and organize into blood vessels. Milder and more severe variants may differ in how much they alter the cell surface protein or its binding to partner proteins.
Treatment
What does that mean for your treatment
No CLEC14A-specific treatment or management approach is currently established for people with a pathogenic or loss of function variant in the CLEC14A gene. The CLEC14A gene is being studied as a marker of tumor blood vessels and as a possible target for drugs that aim to limit their growth.
Gene function
What if the gene works
Blood vessel lining cells use the CLEC14A gene as part of the machinery that helps them connect, move, and shape new vessels. It is most active in endothelial cells, the cells that line the inside of blood vessels. Understanding how the CLEC14A gene supports blood vessel growth helps explain its day to day role in healthy tissue.
The protein made from the CLEC14A gene helps blood vessel lining cells recognize and attach to neighboring cells at their surface. This steady contact supports an organized vessel lining and coordinated behavior across the vessel wall.
This gene supports blood vessel growth by helping vessel lining cells line up, stretch, and form new sprouts. These steps help small vessels branch and reshape as tissues develop and renew.
Its protein helps vessel lining cells move in a coordinated direction. It supports thin cell extensions that sense nearby cues and help guide where a new vessel branch will grow.
The protein from the CLEC14A gene also helps these cells interact with the support material around them. This added grip helps growing vessels stay arranged as cells connect, move, and settle into place.
What is a variant?
A genetic variant is a small difference in the DNA sequence within a gene. These changes are common and are part of normal human diversity, such as differences in appearance, metabolism, or the way the body responds to environmental influences. Many variants do not have any noticeable effect and simply represent natural genetic variation. In some situations, 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 CLEC14A gene can change how much protein is made, how stable it is, and how well it reaches the cell surface. Some CLEC14A gene variants likely have mild effects, slightly weakening protein shape or partner binding, while more disruptive variants may shorten the protein or sharply reduce its production. Changes in the outer binding region can impair normal protein interactions, and variants affecting the membrane-spanning or inner tail regions can alter signaling inside the cell.
How variants are linked to conditions
Variants in the CLEC14A gene do not yet have a broadly confirmed link to a specific health condition in routine medical genetics. Research on CLEC14A gene variants and disease is still developing, so anyone given a CLEC14A-related result should rely on advice from their doctor or genetic counselor for personal interpretation.
A variant is not necessarily a diagnosis
Gene variants are a normal feature of human biology and are widely seen across the general population. Most do not have a direct effect on health and simply represent natural variation among people. For many genes, carrying a variant associated with a condition indicates a possible link rather than a definite diagnosis, especially when several genes and environmental factors play a role. In some situations, however, 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 CLEC14A gene. If a change in this gene appears on genetic testing, the overall impact usually depends on the full clinical picture, including personal and family history.
Inheritance of CLEC14A variants
There is not yet a broadly confirmed disease inheritance pattern tied to the CLEC14A gene, so the inheritance of CLEC14A gene variants is not described in the same clear way as genes linked to well-defined inherited conditions. The CLEC14A gene is located on chromosome 7, which is an autosome, so each person inherits one copy from each parent. That means any CLEC14A variant present in a family can be passed from either parent to a child, but its health meaning depends on the specific variant and the clinical context.
What does my CLEC14A result mean for my family?
There is not yet a broadly confirmed inheritance pattern tied to a specific health condition for the CLEC14A gene, though this understanding can change as research develops. If you have a specific CLEC14A result and want to know what it could mean for relatives, a doctor or genetic counselor can help explain it in the context of your family history.
Genetic information
Genetic testing
How you find out about variants
Genetic testing for CLEC14A variants uses DNA from a blood sample, saliva, or a cheek swab. A laboratory reads the CLEC14A gene and compares it with a usual reference sequence to look for changes. Results may show a variant, no relevant variant, or a finding whose meaning is still unclear.
When should I consider getting a genetic test?
There isn't yet a broadly established, CLEC14A-specific reason for genetic testing in routine care. Decisions about testing are best made with a doctor or genetic counselor who can look at your personal health and family history.
A genetic result is only one part of your health story
A genetic finding can provide useful insight, but what it reveals depends on the condition and the kind of variant involved. Many factors, including lifestyle, environment, age, and medical history, influence how the body works over time. For some conditions, especially those affected 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 may offer a clear answer. In areas such as medication response, genetic results can also help put individual experiences into context.
Pharmacogenetics
How variants shape your response to medicine
Genetic variation can influence how your body responds to medicines. Small differences in genes can affect how a drug is absorbed, broken down, moved through the body, or how strongly it works at its target. This helps explain why the same medication may work well for one person, seem less effective for another, or cause more side effects in someone else. These differences are common and are only one part of the picture, alongside age, overall health, and other medicines.
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 the body processes a drug or how strongly it works. This information can support more informed and more individualized treatment decisions.

Drugs influenced by the CLEC14A gene
When should I seek medical advice?
There is not yet a broadly confirmed role for this gene in how people respond to medicines, so any concerns about symptoms, side effects, or treatment choices are best discussed with your doctor or pharmacist.
