The TNFRSF25 gene helps control the immune system, especially how certain T cells, a type of white blood cell, grow, survive, and switch off when their job is done. In medicine, this gene is important because it helps regulate immune balance and inflammation. If it does not work properly, immune signals can become less controlled, which may play a role in inflammatory or autoimmune conditions.
What is a gene?
A gene is a piece of DNA that carries instructions your cells use to make molecules or regulate activities in the body. Some genes provide the directions for producing proteins, which do much of the work inside cells. Other genes mainly control when certain processes take place, where they happen, and how strongly they occur. Together, genes affect how the body develops and works, and they can influence how you respond to food, stress, or medications.

Overview
TNFRSF25Gene function
What if the gene works
The TNFRSF25 gene helps control immune cell survival, growth, and timely cell death. It is especially important for T cells and helps your body balance inflammation and immune responses.
Risk
What if the gene does not work
Changes in the TNFRSF25 gene can range from milder to more severe and may weaken how immune cells receive survival and activation signals. This can disrupt TNFRSF25 signaling and alter controlled immune responses and cell death.
Treatment
What does that mean for your treatment
A pathogenic or loss-of-function variant in the TNFRSF25 gene does not currently direct a specific approved treatment or drug choice. The TNFRSF25 gene is being studied as part of the TL1A-DR3 immune signaling pathway, with medicines under investigation for inflammatory and immune-related conditions.
Gene function
What if the gene works
The TNFRSF25 gene helps immune cells react to signals from their surroundings and stay coordinated during everyday defense. It is especially important in T cells, where it supports balanced activity, cell survival, and orderly cleanup. Understanding how the immune system controls inflammation is easier when you see TNFRSF25 as one of the surface switches that helps set the response.
The TNFRSF25 gene provides instructions for a surface receptor that lets immune cells pick up outside signals, especially from the TL1A messenger protein. This starts internal signaling that helps cells respond in a coordinated way.
This gene helps certain T cells grow, stay active, and build a focused immune response when needed. It also supports regulatory T cells, which help calm and balance inflammation.
Signals through this receptor help immune cells decide whether to keep working or to enter programmed cell death (a built in way to remove cells). This balance helps the body clear used cells after an immune response.
By shaping the strength and length of immune signaling, the TNFRSF25 gene helps control inflammation during routine immune activity. This supports a measured response rather than one that lasts longer than needed.
What is a variant?
A genetic variant is a small difference in the DNA sequence of a gene. These differences are common and are part of normal human diversity, including variation in appearance, metabolism, and how the body responds to environmental influences. Many variants have no noticeable effect and simply represent natural genetic variation. Sometimes, though, a variant affects how a gene works to a greater extent and may contribute to or cause a genetic condition.
Genetic variants
What if the gene does not work
Variants in the TNFRSF25 gene can change how the TNFRSF25 receptor is built, how stable it is, and how well it reaches the cell surface or passes signals inside immune cells. In plain terms, TNFRSF25 gene variants and protein function are linked through altered partner binding and weaker or misdirected signaling. Milder variants may partly reduce receptor activity, while more severe variants can greatly disrupt the protein or stop it from being made at all.
How variants are linked to conditions
Current evidence on how the TNFRSF25 gene variants are linked to conditions is still developing. The TNFRSF25 gene does not yet have a broadly confirmed link to a specific health condition, and anyone with a confirmed TNFRSF25-related diagnosis should rely on guidance from their doctor or genetic counselor for interpretation.
A variant is not necessarily a diagnosis
Genetic variants are a normal feature of human biology and are common in the general population. Most do not have a direct effect on health and simply contribute to natural human diversity. For many genes, carrying a variant associated with a condition suggests a possible link rather than a definite diagnosis, especially when several genes and environmental factors also play a role. In some situations, however, a single well-characterized variant in a specific gene can be 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 TNFRSF25 gene. If testing found a change in TNFRSF25, its meaning depends on the exact variant and the wider clinical picture, so discussing personal risk with a doctor or genetic counselor is the best next step.
Inheritance of TNFRSF25 variants
There is not yet a broadly confirmed Mendelian pattern for how TNFRSF25 gene variants are inherited in relation to a specific human condition, so the inheritance of TNFRSF25 gene variants is still being clarified as research develops. The TNFRSF25 gene is located on chromosome 1, which is an autosome, so you inherit one copy from each parent. That means any variant in the TNFRSF25 gene could be passed through either side of the family.
What does my TNFRSF25 result mean for my family?
There is not yet a broadly confirmed inheritance pattern tied to a specific health condition for TNFRSF25, and understanding may change as research develops. If you have a TNFRSF25 result and questions about what it could mean for relatives, a doctor or genetic counselor can help explain it in the context of your family history and the exact result.
Genetic information
Genetic testing
How you find out about variants
To find out whether you carry a variant in the TNFRSF25 gene, TNFRSF25 genetic testing uses DNA from a blood sample, cheek swab, or saliva sample. A laboratory reads the gene’s sequence and compares it with the usual reference sequence to identify variants that may help explain personal or family health findings.
When should I consider getting a genetic test?
There is not yet a broadly established reason to get genetic testing focused specifically on the TNFRSF25 gene. Testing decisions are usually based on your personal health history, symptoms, and family history, ideally with guidance from a doctor or genetic counselor.
A genetic result is only one part of your health story
A genetic result can provide meaningful information, but what it shows depends on the condition and the type of variant involved. Many other factors, including lifestyle, environment, age, and medical history, also shape how the body works over time. In some conditions, especially those influenced by many genes, genetic information offers context rather than certainty and is most useful when viewed alongside other parts of care. In other situations, a genetic result may give 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 affect how people respond to medicines. Two people can take the same treatment, yet one may get better benefit while the other may notice less effect or more side effects, partly because their bodies handle the medicine differently. These differences are common and can influence how strongly a drug works, how long it stays in the body, and how sensitive someone is to it.
What is Pharmacogenetics?
Pharmacogenetics is the area of study that examines how genetic differences affect a person’s response to medications. It looks at links between genes and drugs to help explain why the same treatment may work differently from one person to another. For many medicines, genes influence how strongly a drug works or how the body handles it. This information can support more informed, more individualized treatment decisions. To explore this subject in greater detail, you can learn more in the LearnHub.
Drugs influenced by the TNFRSF25 gene
When should I seek medical advice?
There is not yet a broadly confirmed role for this gene in guiding medication choice or predicting how well a medicine will work. If you have concerns about side effects, treatment response, or your overall health, it is best to discuss them with your doctor.
History
TNFRSF25 entered the scientific literature in the late 1990s, when researchers identified it as a new member of the tumor necrosis factor receptor family. Early papers used several names for the same gene, including DR3, APO-3, LARD, TRAMP, and WSL-1, reflecting how different groups were studying it from different angles. Scientific classifications changed as researchers learned more about the gene. Over time, the field settled on TNFRSF25 as the standard name, which helped unify research findings. This naming history is the most notable part of the gene’s story, marking a period when many immune related genes were being discovered and organized into clearer families.
