The PARP14 gene helps cells control inflammation, respond to stress, and regulate which other genes are turned on or off. The protein made by this gene supports immune signaling and may also help cells cope with DNA damage. If the PARP14 gene does not work well, immune responses may become less balanced and cell growth signals may shift, which has been linked in research to asthma, some immune conditions, and certain cancers. PARP14 is mainly known in medical research rather than popular culture.
What is a gene?
Genes are sections of DNA that carry instructions your cells use to make molecules or direct processes in the body. Some genes hold the information needed to produce proteins, the parts of cells that do much of the work. Others mainly help control when certain processes happen, where they happen, and how strongly they run. Taken together, genes affect how the body develops and works, and they can influence how you respond to food, stress, or medications.

Overview
PARP14Gene function
What if the gene works
The PARP14 gene helps control immune signaling and how some genes are switched on. Its protein also supports cell survival during stress and may aid DNA repair.
Risk
What if the gene does not work
Milder to more severe variants in the PARP14 gene can reduce how well cells add small chemical tags to certain proteins, a signaling step that helps control immune responses and when other genes are turned on or off.
Treatment
What does that mean for your treatment
No PARP14-specific treatment or management approach is currently established for people with a pathogenic variant in the PARP14 gene. PARP14 is being studied as a possible drug target in some cancers and inflammatory conditions, but this has not yet changed routine care.
Gene function
What if the gene works
In daily cell activity, the PARP14 gene helps cells respond to signals and adjust how strongly certain genes are used. Its protein adds small chemical tags to other proteins, which can change how those proteins behave. This helps explain what the PARP14 gene does in the body during routine immune and cell control processes.
The PARP14 gene helps place small chemical tags on certain proteins. These tags can fine tune how proteins send signals, move, or work with other cell helpers.
Its protein helps control which genes are turned on after a cell receives outside signals. This lets cells adjust routine jobs in a more coordinated way.
One well studied part of PARP14 gene function in the immune system is helping immune cells respond to message signals from nearby cells. This supports coordinated inflammation and antibody related activity.
What is a variant?
A genetic variant is a minor change in a gene’s DNA sequence. These changes are common and help shape normal differences among people, including appearance, metabolism, and the way the body reacts to environmental influences. Many variants do not cause any noticeable effects and are simply part of natural genetic variation. At times, though, a variant can change how a gene works more significantly and may contribute to or lead to a genetic condition.
Genetic variants
What if the gene does not work
Variants in the PARP14 gene can change the PARP14 protein’s shape, stability, or enzyme activity, and some may weaken how it interacts with other proteins. Research on how variants influence the PARP14 gene's function suggests a spectrum, with some missense variants causing only a partial drop in activity while more disruptive variants can lead to a much larger loss of function or an unstable protein. The functional effect often depends on where the variant occurs and how much of the protein is altered.
How variants are linked to conditions
The PARP14 gene does not yet have a broadly confirmed link to a specific inherited health condition, although research on how PARP14 gene variants are linked to conditions is still developing. Anyone with a confirmed PARP14-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 routine part of human biology and are common throughout the general population. Most do not have a direct effect on health and simply reflect natural human diversity. For many genes, carrying a variant associated with a condition indicates a possible link rather than a definite diagnosis, especially when multiple genes and environmental factors are involved. In some cases, 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 isn't yet broadly confirmed evidence on specific factors that increase or reduce health risk related to the PARP14 gene. Anyone with concerns about personal risk or a family history of related health problems should speak with a doctor or genetic counselor.
Inheritance of PARP14 variants
There is not yet a broadly confirmed Mendelian pattern for how PARP14 gene variants are inherited in relation to a specific human genetic condition. Current understanding of PARP14 gene inheritance is still developing, and future research may clarify whether any consistent disease related pattern exists. The PARP14 gene is located on chromosome 3, which is an autosome, so you inherit one copy from each parent. This means any PARP14 gene variant can be passed through either side of the family.
What does my PARP14 result mean for my family?
There is not yet a broadly confirmed inheritance pattern tied to a specific health condition for PARP14, and this understanding can change as research develops. If you have a specific PARP14 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 personal and family history.
Genetic information
Genetic testing
How you find out about variants
Genetic testing for variants in the PARP14 gene uses a blood, saliva, or cheek swab sample to read this gene’s DNA and look for changes. Results may show that no variant was found, that a variant is present, or that a change needs more interpretation alongside your personal and family history.
When should I consider getting a genetic test?
There is not yet a broadly established, PARP14-specific reason to get genetic testing in routine care. Decisions about testing are usually based on your personal health, family history, and the goal of testing, and are best discussed with a doctor or genetic counselor.
A genetic result is only one part of your health story
A genetic result can provide valuable insight, but how much it can tell you varies depending on the condition and the type of variant involved. How the body functions over time is shaped by many factors, including lifestyle, environment, age, and medical history. For some conditions, especially those influenced by many genes, genetic information provides context rather than certainty and is most useful when considered alongside other parts of care. In other situations, a genetic result can 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 affect how people respond to medicines. Small differences in DNA can change how the body breaks down a drug, moves it through the body, or responds at the drug’s target, so the same treatment may work better for some people than for others. This is common and can influence how much benefit a person gets from a medicine or how sensitive they are to side effects.
What is Pharmacogenetics?
Pharmacogenetics examines how genetic differences affect a person’s response to medications. By studying connections between genes and drugs, it helps explain why the same treatment may work differently from one person to another. For many medicines, genes can influence both how strongly a drug works and how the body processes it. This information can support more informed, more individualized treatment decisions. You can explore this topic further in the LearnHub.
Drugs influenced by the PARP14 gene
When should I seek medical advice?
There is not yet a broadly confirmed role for this gene in guiding medication choices, so general questions about side effects, treatment response, or new symptoms are best discussed with your doctor. Research on the PARP14 gene is ongoing, especially in cancer and inflammation, but it is not currently used in routine prescribing.
History
Researchers identified the PARP14 gene in the early 2000s during work on a larger family of PARP genes. It was first described in cancer related research and was initially also referred to as BAL2 in studies of diffuse large B cell lymphoma. From these first observations, research expanded steadily. As gene sequencing methods improved, PARP14 was placed more clearly within the PARP family and its different forms were mapped in more detail. Interest in the PARP14 gene later grew through immunology and cancer biology research, which helped move it from a little known finding to a recognized part of modern genetics. Its history is mainly a scientific one, shaped by advances in gene discovery over the past two decades.
