Your body relies on this gene to help switch on part of the immune response, especially during viral infections. The IFI27 gene helps cells react to interferon, an alarm signal the body uses when fighting viruses. If it does not work as expected, the body’s response to infection may be less well coordinated. It is not a gene most people hear about in daily life, but it gained attention during the COVID-19 pandemic because high IFI27 activity was studied as a marker of viral illness.
What is a gene?
Each gene is a stretch of DNA that holds instructions your cells use to make molecules or regulate processes in the body. Some genes carry the directions for producing proteins, the parts of cells that do much of the work. Others mainly control when certain processes happen, where they take place, and how strongly they are carried out. Taken together, genes affect how the body develops and functions, and they can influence how you respond to food, stress, or medications.

Overview
IFI27Gene function
What if the gene works
The IFI27 gene helps cells respond to interferon, a signal the body uses during viral infections. It is most active in immune and lining tissues and may influence how cells adapt to stress and survive.
Risk
What if the gene does not work
Changes in the IFI27 gene can range from milder to more severe and may alter how cells respond to interferon signals, a key part of antiviral defense. This can affect IFI27 protein activity and related cell stress pathways.
Treatment
What does that mean for your treatment
No IFI27-specific treatment or drug selection approach is currently established for pathogenic variants in the IFI27 gene. IFI27 is mainly being studied as a biomarker in viral infections and some cancers, not as a target for approved therapy.
Gene function
What if the gene works
When your body senses a viral infection, cells turn on IFI27 as part of an early immune response. This gene is most active after interferon signals, which are chemical messages that alert nearby cells to trouble. In normal cell function, IFI27 helps cells shift into a defensive state and supports healthy responses to stress.
IFI27 is turned on by interferons, the body’s early immune alarm signals. This helps cells respond in a coordinated way when they detect infection.
Once active, IFI27 helps cells shift into a state that helps defend against viruses. This is part of how the IFI27 gene helps fight viral infections.
The IFI27 protein works near mitochondria, the parts of cells that help manage energy and stress. From there, it supports normal links between immune signaling and everyday cell stress responses.
What is a variant?
A genetic variant is a small difference in the DNA sequence within a gene. These differences are common and help shape normal human diversity, including differences in appearance, metabolism, or how the body responds to environmental influences. Many variants do not have 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 IFI27 gene can change how much protein a cell makes or alter the protein’s shape, stability, and placement in cell membranes. Studies of how variants in the IFI27 gene affect protein function suggest that some changes have mild effects, while more severe variants may sharply reduce protein production or make the protein unstable. Variants that disrupt the coding sequence can also weaken how IFI27 interacts with other cell components.
How variants are linked to conditions
The IFI27 gene does not yet have a broadly confirmed link to a specific inherited health condition, so clear IFI27 gene variant related conditions have not been established. Research may refine these associations over time, and anyone with a confirmed IFI27 finding should use advice from their doctor or genetic counselor to understand what it means for them.
A variant is not necessarily a diagnosis
Genetic variants are common across the general population and are a normal feature of human biology. Most do not directly affect health and instead reflect the natural diversity seen among people. For many genes, having a variant associated with a condition points to a possible link rather than a certain diagnosis, particularly when several genes and environmental influences are part of the picture. In other situations, though, one well characterized variant in a particular gene is 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 IFI27 gene. Anyone with concerns about personal risk or test results should speak with a doctor or genetic counselor.
Inheritance of IFI27 variants
There is not yet a broadly confirmed disease specific inheritance pattern for the IFI27 gene, so how IFI27 gene variants are inherited is not linked to one well established dominant, recessive, or X linked condition. IFI27 is on chromosome 14, which is an autosome, so you inherit one copy of the IFI27 gene from each parent. In practice, a variant in this gene could be passed through either side of the family.
What does my IFI27 result mean for my family?
There is not yet a broadly confirmed inherited pattern linking IFI27 to a specific genetic condition in families, though this can become clearer as research grows. If you have a specific IFI27 result and want to understand 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
Testing for IFI27 gene variants usually uses blood, saliva, or a cheek swab. A lab reads the DNA code in the IFI27 gene and compares any changes with trusted reference data to classify them. Results may show a benign variant, a variant of uncertain significance, or a clinically important variant.
When should I consider getting a genetic test?
There is not yet a widely accepted medical reason to order genetic testing just for the IFI27 gene. Testing decisions 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
Genetic results can provide useful insight, but the amount they can tell you varies with the condition and the kind of variant involved. How the body functions over time is also shaped by many 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 other parts of care. In other situations, a genetic result can give a clear answer. In areas like medication response, genetic findings can also help put a person’s individual experience into context.
Pharmacogenetics
How variants shape your response to medicine
Genetic variation can affect how people respond to medicines. Some people break down a drug more quickly or more slowly, while others may be more or less sensitive to the same dose. This helps explain why a treatment works well for one person, causes side effects in another, or seems to have little effect in someone else.
What is Pharmacogenetics?
Pharmacogenetics examines the way genetic differences affect a person’s response to medicines. It studies gene-drug patterns to help explain why the same treatment may work differently in different people. With many medications, genes influence both how powerful a drug’s effects are and how the body handles it. This information can support treatment decisions that are more informed and more tailored to the individual. More detail on this topic is available in the LearnHub.
Drugs influenced by the IFI27 gene
When should I seek medical advice?
There is not yet a broadly confirmed role for this gene in guiding medicine choice or dose, so concerns about side effects, treatment response, or changes to your medicines are best discussed with your doctor.
