The IFI35 gene helps your cells respond to interferons, which are immune alarm signals released during infections, especially viral infections. If this gene does not work properly, those signals may become less balanced, which can affect inflammation and how the body handles germs. This gene plays an important role in the body’s early immune defense system.
What is a gene?
Genes are sections of DNA that give your cells instructions for making molecules or managing processes in the body. Some genes carry the information needed to produce proteins, the parts of cells that do much of the work. Other genes mainly regulate when certain processes take place, where they happen, and how active they are. Together, genes affect how the body develops and functions, and they can also influence how you respond to food, stress, or medications. For a deeper look at this topic, you can find more in the LearnHub.
Overview
IFI35Gene function
What if the gene works
The IFI35 gene helps regulate the body’s early immune response after interferon signals during infection. Its protein supports how cells respond to viruses and other immune triggers.
Risk
What if the gene does not work
Variants in the IFI35 gene can range from milder to more severe and may reduce how cells handle interferon signals and antiviral responses. This can weaken or alter inflammatory signaling between immune cells.
Treatment
What does that mean for your treatment
No IFI35-specific treatment or management approach is currently established in clinical guidelines. The IFI35 gene is being studied as a marker of immune activity and inflammation in some infections, autoimmune conditions, and cancers.
Gene function
What if the gene works
When cells detect infection, they can turn on the IFI35 gene as part of an early immune response. The protein made from this gene helps immune messages move through the cell in a controlled way. It is mainly involved in antiviral defense and inflammation control.
The IFI35 gene is turned on by interferons, which are alarm signals cells release during infection. Its protein helps cells pass along these messages and keep the immune response coordinated.
IFI35 works with partner proteins to support the body’s early antiviral defenses. This is part of how the IFI35 gene helps the immune system respond to viral infection and coordinate other defense signals.
The IFI35 gene also helps shape inflammatory signals, which tell immune cells when to become more active. By tuning these messages, it supports a measured response to infection and cell stress.
What is a variant?
A genetic variant is a minor change in the DNA sequence within a gene. These changes are common and help explain normal differences among people, such as appearance, metabolism, or the way the body responds to environmental influences. Many variants do not have any noticeable effect and are simply part of natural genetic variation. At times, though, a variant can change how a gene works more clearly and may contribute to or cause a genetic condition.
Genetic variants
What if the gene does not work
Variants in the IFI35 gene can change the protein’s shape, stability, or how well it binds to partner proteins, which may alter signaling inside cells. In studies of how IFI35 gene variants affect protein function, some changes appear mild and may slightly lower protein stability, while more disruptive variants can greatly reduce protein production or create a shortened protein that breaks down early. This creates a spectrum of effects, with different variants causing different degrees of reduced cellular activity.
How variants are linked to conditions
The IFI35 gene does not yet have a broadly confirmed link to a specific health condition, and current findings on conditions linked to IFI35 gene variants are still being clarified. Anyone with a confirmed IFI35-related diagnosis should rely on guidance from their doctor or genetic counselor rather than general information.
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 instead reflect natural human diversity. For many genes, carrying a variant associated with a condition suggests a possible link rather than a definite diagnosis, especially when multiple 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 is not yet broadly confirmed evidence on specific factors that increase or reduce health risk related to the IFI35 gene. If IFI35 is part of your test results and you are worried about what it means for you or your family, a doctor or genetic counselor can help put it in context.
Inheritance of IFI35 variants
The inheritance of IFI35 gene variants is not tied to a single, broadly confirmed disease pattern at this time. As research stands, there is not yet a well-established autosomal dominant, autosomal recessive, or X-linked condition consistently linked to the IFI35 gene. The IFI35 gene is located on chromosome 17, which is an autosome, so you inherit one copy from each parent. In general, that means any change in the IFI35 gene can be passed through either side of the family.
What does my IFI35 result mean for my family?
There is not yet a broadly confirmed inheritance pattern tied to a specific health condition for IFI35. If you have a specific IFI35 result and want to understand what it could mean for close relatives, a doctor or genetic counselor can 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 an IFI35 variant, genetic testing for IFI35 variants reads DNA from a blood, saliva, or cheek swab sample and checks the IFI35 gene for changes. 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 IFI35-specific medical reason for genetic testing. Decisions about 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 test results can provide meaningful insight, but how much they reveal depends on the condition and the specific type of variant. 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 provides context rather than certainty and is best understood together with other parts of care. In other situations, a genetic result can offer a clear answer. In areas such as medication response, these results can also help place individual experiences in context.
Pharmacogenetics
How variants shape your response to medicine
Genetic variation can affect how people respond to medicines. This helps explain why the same treatment may work well for one person, seem less effective for another, or cause more side effects in someone else. Small differences in how the body breaks down, moves, or reacts to a drug are common and can influence both benefit and sensitivity.
What is Pharmacogenetics?
Pharmacogenetics examines how genetic differences affect the way people respond to medications. It studies connections between genes and drugs to help 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 more informed, individualized treatment decisions. More on this topic is available in the LearnHub.
Drugs influenced by the IFI35 gene
When should I seek medical advice?
There is not yet a broadly confirmed role for this gene in guiding medication choices. General concerns about side effects, new symptoms, or whether a treatment is helping are best discussed with your doctor, especially before starting, stopping, or changing any medicine.
