The protein made by the UHRF1 gene helps cells keep important chemical tags on DNA, which helps the right genes stay switched on or off as new cells form. If it does not work properly, cells can lose some of this control, which may affect growth and development and has been linked to rare inherited conditions. Higher than usual UHRF1 activity is also being studied in cancer because it may help abnormal cells keep dividing.
What is a gene?
Genes are sections of DNA that provide cells with instructions for making molecules or regulating processes in the body. Some genes hold the directions for producing proteins, which are the working parts of cells. Other genes mainly determine when certain processes happen, where they take place, and how strongly they are carried out. In combination, genes affect how the body develops and works, and they can influence how you respond to food, stress, or medications.

Overview
UHRF1Gene function
What if the gene works
The UHRF1 gene helps cells copy chemical DNA tags during cell division. This helps keep the right genes switched on or off and supports normal growth and DNA stability.
Risk
What if the gene does not work
Milder or more severe variants in the UHRF1 gene can weaken how cells copy DNA methylation marks, the chemical tags that help control gene activity. This may disrupt normal gene switching and how well DNA stays stable during cell division.
Treatment
What does that mean for your treatment
For a pathogenic or loss-of-function variant in the UHRF1 gene, no UHRF1-specific treatment or management approach is currently established in clinical guidelines. The UHRF1 gene is being studied mainly as a cancer biomarker and possible drug target, especially in epigenetic cancer research.
Gene function
What if the gene works
When cells divide, they need to copy not only DNA but also the small chemical tags that help control gene activity. The UHRF1 gene supports this process. It helps cells recognize old tags and copy them onto newly made DNA. This is a key part of how the UHRF1 gene helps maintain DNA methylation during cell division.
The UHRF1 gene helps cells preserve DNA methylation, a set of small chemical tags that influence whether genes are used. It does this while DNA is being copied, helping new cells keep a similar pattern of gene activity.
Its protein can recognize tag patterns on DNA and on histones (proteins that DNA wraps around). Reading both signals helps cells match older control instructions with newly copied DNA.
The UHRF1 gene helps bring the enzyme that adds DNA tags to the right place on freshly copied DNA. This supports a steady handoff of gene control marks from one cell generation to the next.
What is a variant?
A genetic variant is a small alteration in the DNA sequence of a gene. These changes are common and help shape normal human diversity, including differences in appearance, metabolism, or how the body responds to environmental influences. Many variants have no 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 UHRF1 gene can change the protein’s shape, stability, or ability to attach to methylated DNA and histones (the proteins DNA wraps around). In descriptions of how UHRF1 gene variants affect protein function, many changes weaken its grip on methylated DNA or proteins and disrupt DNA methylation, a chemical tagging pattern that helps cells control gene activity. Milder variants may leave some activity, while more severe loss of function variants can reduce protein levels or block binding regions.
How variants are linked to conditions
The UHRF1 gene does not yet have a broadly confirmed link to a specific health condition, although research on how UHRF1 gene variants are linked to conditions is still developing. Anyone with a confirmed variant in the UHRF1 gene should use their own test report and follow-up care with their doctor or genetic counselor for guidance that fits their situation.
A variant is not necessarily a diagnosis
Genetic variants are a common and normal feature of human biology. Most do not directly affect health and simply contribute to the natural differences seen among people. For many genes, having a variant associated with a condition points to a possible link rather than a clear diagnosis, particularly when several genes and environmental influences play a role. In some 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 is not yet broadly confirmed evidence on specific factors that increase or reduce health risk related to the UHRF1 gene. If a change in UHRF1 has been found in you or your family, a doctor or genetic counselor can help explain what it may mean for your personal risk.
Inheritance of UHRF1 variants
For families trying to understand how UHRF1 gene variants are inherited, there is not yet a broadly confirmed disease specific inheritance pattern tied to the UHRF1 gene that is supported by broad clinical consensus. This can change as research develops and more families are studied. The UHRF1 gene is located on chromosome 19, which is an autosome. That means each person inherits one copy of the UHRF1 gene from each parent.
What does my UHRF1 result mean for my family?
There is not yet a broadly confirmed inheritance pattern tied to a specific health condition for UHRF1, although this can change as research grows. If you have a specific UHRF1 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 variant found.
Genetic information
Genetic testing
How you find out about variants
Genetic testing for UHRF1 variants usually uses a blood sample or saliva. A lab reads the DNA code of the UHRF1 gene, often in a test that checks many genes at once, and compares it with the usual sequence. The report then says whether a variant was found and how strongly it is linked to disease.
When should I consider getting a genetic test?
There isn’t yet a broadly established UHRF1-specific reason for genetic testing in routine care. Testing decisions are usually based on your personal health and family history, with a doctor or genetic counselor helping decide whether a broader genetic test makes sense.
A genetic result is only one part of your health story
A genetic result can be highly informative, but how much it reveals varies by the condition involved and the kind of variant found. Many other factors also shape how the body works over time, including lifestyle, environment, age, and medical history. For some conditions, especially those affected by many genes, genetic information offers context rather than certainty and is most useful when considered along with 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. Small differences in genes can change how the body breaks down a drug, moves it through the body, or responds to it at the target tissue. This helps explain why the same treatment works well for one person, works less well for another, or causes more side effects in someone else. These differences are common and are one part of the bigger picture, along with age, liver and kidney function, other medicines, and overall health.
What is Pharmacogenetics?
Pharmacogenetics examines how genetic differences affect the way a person responds to medications. By looking at connections between genes and drugs, it helps explain why the same treatment may work differently from one person to another. For many medicines, genes influence how the body processes a drug and how strong its effects are. This information can support more informed and individualized treatment decisions. If you want to explore this subject in greater detail, more information is available in the LearnHub.
Drugs influenced by the UHRF1 gene
When should I seek medical advice?
There is not yet a broadly confirmed role for this gene in guiding medication choices. Talk with your doctor if you have unusual side effects, a medicine is not working as expected, or you have questions before starting or changing treatment.
History
Research on the UHRF1 gene grew as scientists in the late 1990s and early 2000s searched for proteins linked to cell growth and cancer biology. It was first described under other names, including ICBP90 in humans and NP95 in mice, before these findings were brought together under the name UHRF1. Initially understood only through visible traits, later recognized as tied to a specific gene, its story reflects the broader rise of epigenetics research. From these first observations, research expanded steadily. By the 2000s, studies showed that UHRF1 had a central place in how cells copy chemical marks on DNA during cell division. That work made the UHRF1 gene an important part of modern cancer and gene regulation research.
