The LRRC25 gene helps fine tune the body’s early immune response by helping switch off certain antiviral and inflammation signals after they have done their job. If it does not work properly, these signals may stay on too long or be too weak, which can affect how the body responds to infection and inflammation. This gene plays an important role in keeping immune activity balanced rather than constantly switched on.
What is a gene?
A gene is a stretch 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, the parts of cells that do the work. Other genes mainly control when certain processes happen, where they take place, and how strongly they run. Together, genes affect how the body develops and functions, and they can influence how you respond to food, stress, or medications.

Overview
LRRC25Gene function
What if the gene works
The LRRC25 gene helps control parts of the immune system. Its protein supports the removal of certain immune signaling proteins after they have done their job, which helps keep antiviral responses and inflammation more balanced.
Risk
What if the gene does not work
Changes in the LRRC25 gene can range from milder to more severe variants and may reduce how well cells clear certain signaling proteins. This can alter innate immune signaling, especially pathways that help control antiviral and inflammatory responses.
Treatment
What does that mean for your treatment
No LRRC25-specific treatment or management approach is currently established for people with a pathogenic or loss-of-function variant in the LRRC25 gene.
Gene function
What if the gene works
Your immune system needs careful timing, not just a strong reaction. The LRRC25 gene helps cells fine tune some early antiviral signals so immune activity stays controlled. Understanding how the LRRC25 gene works makes it easier to see how cells keep their alarm system active for the right length of time.
The LRRC25 gene helps immune cells regulate early antiviral alarm signals after a possible virus is detected. Its protein helps control activity around RIG-I, a sensor that recognizes viral genetic material.
Inside cells, the LRRC25 gene helps guide certain immune signaling proteins to the cell’s cleanup system. This orderly removal helps antiviral signals rise and settle in a controlled way.
What is a variant?
A genetic variant is a minor change in the DNA sequence within 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 have any noticeable effect and simply represent natural genetic variation. Sometimes, however, 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 LRRC25 gene can change the shape or stability of the LRRC25 protein, which may weaken how it binds partner proteins inside the cell. Studies of how LRRC25 gene variants affect protein function suggest that milder changes may partly reduce protein activity, while more disruptive variants can shorten the protein, make it unstable, or stop it from reaching the right cellular location. These differences can lead to a spectrum of reduced function rather than a single uniform effect.
How variants are linked to conditions
Variants in the LRRC25 gene do not yet have a broadly confirmed link to a specific health condition, so published information about LRRC25 gene related conditions is still developing. If you have a confirmed variant in the LRRC25 gene, your doctor or genetic counselor can interpret it in the context of your personal and family history.
A variant is not necessarily a diagnosis
Genetic variants are a usual feature of human biology and are widely found in the general population. Most do not have a direct effect on health and instead reflect normal 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 are involved. In some cases, though, one 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 isn't yet broadly confirmed evidence on specific factors that increase or reduce health risk related to the LRRC25 gene. If a change in LRRC25 is found on genetic testing, your overall risk can still depend on the exact change and your personal and family history. Anyone with concerns about personal risk should speak with a doctor or genetic counselor.
Inheritance of LRRC25 variants
For families trying to understand how LRRC25 gene variants are inherited, there is not yet a broadly confirmed disease specific inheritance pattern for the LRRC25 gene. This may become clearer as research develops. The LRRC25 gene is located on chromosome 19, which is an autosome, so a person inherits one copy from each parent. That means any LRRC25 variant found in testing would generally be traced through the usual inheritance of autosomal genes within a family.
What does my LRRC25 result mean for my family?
There is not yet a broadly confirmed inheritance pattern tied to a specific health condition for LRRC25, and this picture may become clearer as research grows. If you have a specific LRRC25 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
LRRC25 genetic testing checks for variants in the LRRC25 gene using a blood sample, saliva, or a cheek swab. Most labs read the DNA sequence and compare it with a reference sequence to see whether a variant is present. Results may identify a benign variant, a disease-causing variant, or a variant of uncertain significance.
When should I consider getting a genetic test?
There is not yet a broadly established LRRC25-specific clinical reason for testing. Decisions about genetic testing are best made with a doctor or genetic counselor, based on your symptoms and family history.
A genetic result is only one part of your health story
Genetic results can provide useful insight, although how informative they are depends on the condition and on the specific type of variant. Over time, the way the body functions is also shaped by many other factors, including lifestyle, environment, age, and medical history. For some conditions, particularly those affected by many genes, genetic information offers context rather than certainty and makes the most sense when considered with the rest of a person’s care. In other situations, a genetic result can give a clear answer. In areas like response to medications, genetic findings may also 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 DNA can change how the body absorbs, breaks down, or responds to a drug, so the same treatment may work well for one person but less well for another. These differences are common and can influence how much benefit a medicine gives or how sensitive someone is to side effects.
What is Pharmacogenetics?
Pharmacogenetics examines how genetic differences can shape the way a person responds to medication. By looking at links between genes and drugs, it helps explain why the same treatment can work differently from one person to another. For many medicines, genes influence both how strongly a drug works and how the body processes it. This information can support treatment decisions that are more informed and more individualized. More detail on this topic is available in the LearnHub.
Drugs influenced by the LRRC25 gene
When should I seek medical advice?
There is not yet a broadly confirmed role for this gene in guiding medication choices, so questions about symptoms, side effects, or treatment changes are best discussed with your doctor. If a medicine is not working as expected or is causing problems, your doctor can review the full picture and decide what to do next.
