The NUDT22 gene helps cells recycle a sugar linked molecule to make some of the building blocks needed for DNA and RNA. If the NUDT22 gene does not work well, cells may struggle to keep these supplies balanced, which can affect normal growth and repair. This gene plays an important role in basic cell metabolism, and researchers are studying it because rapidly growing cells may rely on this pathway more than others.
What is a gene?
Genes are sections of DNA that provide cells with instructions 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 regulate when certain processes happen, where they take place, and how strongly they operate. In combination, genes influence how the body develops and functions, and they can shape how you respond to food, stress, or medications.

Overview
NUDT22Gene function
What if the gene works
The NUDT22 gene helps cells break down UDP-glucose, a molecule involved in sugar handling. This supports recycling of building blocks that cells use to make RNA and DNA.
Risk
What if the gene does not work
Milder to more severe variants in the NUDT22 gene can reduce how well its enzyme handles certain uridine-containing molecules in cells. This may disrupt pyrimidine recycling and the balance of some DNA and RNA building blocks.
Treatment
What does that mean for your treatment
No treatment or drug choice is currently guided by pathogenic or loss-of-function variants in the NUDT22 gene in clinical guidelines. The NUDT22 gene is being studied in basic and early cancer research because it affects how cells handle the building blocks of DNA and RNA, but this has not led to gene-specific care.
Gene function
What if the gene works
Your cells need a steady supply of small molecules to copy DNA, make RNA, and keep basic metabolism moving. The NUDT22 gene helps manage that supply by breaking down UDP-glucose, a molecule that connects sugar use with nucleotide production. Knowing how the NUDT22 gene works helps make sense of how cells keep a usable supply of building blocks for DNA and RNA.
The NUDT22 gene makes an enzyme that splits UDP-glucose into smaller parts. This step helps cells control this sugar based molecule and reuse one part, UMP, as a small building block for RNA and related molecules.
By creating UMP, the NUDT22 gene links sugar metabolism with the supply of building blocks used to make genetic material. This supports routine cell growth and the extra demand that comes when cells prepare to copy DNA.
What is a variant?
A genetic variant is a minor change in the DNA sequence of 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. In some cases, though, a variant can more substantially change how a gene functions and may contribute to or cause a genetic condition.
Genetic variants
What if the gene does not work
Variants in the NUDT22 gene may change the shape or stability of its enzyme, which can lower how well it processes certain molecules inside cells. Milder variants may leave some activity intact, while more severe variants, including changes that create a shortened protein, can greatly reduce or stop activity. This range helps explain how NUDT22 gene variants affect protein function.
How variants are linked to conditions
The NUDT22 gene does not yet have a broadly confirmed link to a specific health condition, though research on NUDT22 gene variants and disease risk is still developing. If you carry a variant in the NUDT22 gene, its meaning is best interpreted with your doctor or genetic counselor alongside your personal health and family history.
A variant is not necessarily a diagnosis
Variants in genes are a usual part of human biology and are widespread in the general population. Most do not have a direct effect on health and simply reflect normal human diversity. For many genes, having a variant associated with a condition indicates a possible link rather than a confirmed diagnosis, especially when several genes and environmental factors contribute. In some situations, though, a single 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 NUDT22 gene. Anyone with concerns about their personal or family risk can speak with a doctor or genetic counselor.
Inheritance of NUDT22 variants
For families trying to understand how NUDT22 gene variants are inherited, there is not yet a broadly confirmed Mendelian inheritance pattern tied to a specific NUDT22 related condition. This may become clearer as research develops and as more families are studied. The NUDT22 gene is located on chromosome 11, which is an autosome, so each person inherits one copy from each parent.
What does my NUDT22 result mean for my family?
There is not yet a broadly confirmed inheritance pattern tied to a specific health condition for NUDT22. If you have a NUDT22 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 and the exact result.
Genetic information
Genetic testing
How you find out about variants
Genetic testing for variants in the NUDT22 gene examines your DNA from blood, saliva, or a cheek swab and compares the NUDT22 gene with a reference sequence. The report can show whether a variant is present and whether it is known to affect health.
When should I consider getting a genetic test?
There is not yet a broadly established, NUDT22-specific reason to have genetic testing in routine care. Decisions about testing are usually based on your personal health and family history, and are best made with a doctor or genetic counselor.
A genetic result is only one part of your health story
Genetic results can provide useful insight, but how much they reveal depends on the condition and the kind of variant involved. Over time, many factors influence how the body functions, including lifestyle, environment, age, and medical history. For some conditions, especially those shaped by many genes, genetic information provides context rather than certainty and is most helpful when considered alongside other parts of care. In other situations, a genetic result may offer a clear answer. In areas like 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. Two people can take the same treatment at the same dose, yet one may get better benefit while the other may be more sensitive or notice more side effects. This happens in part because inherited differences can change how the body breaks down, moves, or responds to a drug, and these differences are common.
What is Pharmacogenetics?
Pharmacogenetics looks at how genetic differences can shape a person’s response to medications. It studies the relationship between genes and drugs to help explain why the same treatment may work differently from one person to another. For many medicines, genes can affect how strongly a drug works or how the body processes it. This information can support more informed and individualized treatment decisions. More about this topic is available in the LearnHub.
Drugs influenced by the NUDT22 gene
When should I seek medical advice?
There is not yet a broadly confirmed role for this gene in guiding medicine choice or predicting medication response. If you have side effects, your treatment is not working as expected, or you have questions about supplements or prescriptions, discuss this with your doctor or pharmacist.
