The NUDT13 gene helps cells manage certain small molecules inside mitochondria, the parts of cells that make energy. It appears to act as a cleanup enzyme, breaking down compounds that could interfere with normal energy balance if they build up. If the NUDT13 gene does not work as expected, cells may handle oxidative stress less smoothly and energy-related processes may be less stable. NUDT13 is mainly discussed in research settings rather than everyday health news.
What is a gene?
Genes are stretches of DNA that carry instructions your cells use to make molecules or regulate processes in the body. Some genes provide the directions for producing proteins, the parts of cells that do the work. Others mainly help determine when certain processes happen, where they happen, and how strongly they run. Taken together, genes affect how the body develops and functions, and they can shape how you respond to food, stress, or medications.

Overview
NUDT13Gene function
What if the gene works
The NUDT13 gene helps mitochondria, the parts of cells that make energy, break down certain damaged energy molecules. This cleanup supports normal cell metabolism and may help limit buildup during oxidative stress.
Risk
What if the gene does not work
Milder to more severe variants in the NUDT13 gene can reduce how well mitochondria break down certain energy carrying molecules. This may change enzyme activity to different degrees and alter the cell’s internal chemical balance.
Treatment
What does that mean for your treatment
No treatment or medicine choice is currently guided by pathogenic variants in the NUDT13 gene. The NUDT13 gene is mainly being studied in early laboratory research on how cells handle damaged molecules involved in energy use, not as an established drug target.
Gene function
What if the gene works
Your mitochondria, the parts of cells that make usable energy, need careful control of many small molecules. The NUDT13 gene helps with this routine cleanup by making an enzyme that breaks down selected nucleotide based compounds inside mitochondria. Understanding NUDT13 gene function helps explain how cells keep their energy chemistry balanced.
The NUDT13 gene makes an enzyme that splits apart certain nucleotide related molecules inside mitochondria. This cleanup step helps prevent unnecessary buildup and keeps the mitochondrial environment orderly.
Its enzyme can act on reduced energy carriers such as NADH and NADPH, which cells use during normal energy production and chemical reactions. By breaking down selected forms at the right time, it helps maintain a healthy internal balance.
What is a variant?
A genetic variant is a small difference in the DNA sequence within a gene. These differences are common and are part of normal human diversity, such as 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 the function of a gene more substantially and may contribute to or cause a genetic condition.
Genetic variants
What if the gene does not work
Variants in the NUDT13 gene can alter the enzyme’s shape, stability, or transport into mitochondria, which may reduce its ability to process NADH and NADPH. How NUDT13 gene variants affect protein function often depends on where the DNA change occurs. Milder variants may leave some activity, while more severe variants can disrupt the enzyme’s active part or make the protein break down sooner, leaving little or no activity.
How variants are linked to conditions
At present, the NUDT13 gene does not yet have a broadly confirmed link to a specific health condition in routine medical genetics, and this picture can change as research develops. If you have a reported variant in the NUDT13 gene, your doctor or genetic counselor can explain what that result means in the context of your own health and family history.
A variant is not necessarily a diagnosis
Genetic variants are a usual part of human biology and are widespread in the general population. Most do not have a direct effect on health and instead reflect normal 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 are involved. In some situations, though, a single well-characterized variant in a particular gene can be 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 NUDT13 gene. If NUDT13 is part of your test results and you have concerns about what it may mean for you or your family, a doctor or genetic counselor can help put it in context.
Inheritance of NUDT13 variants
There is not yet a broadly confirmed disease related inheritance pattern for the NUDT13 gene, so NUDT13 gene inheritance is not currently described as autosomal dominant, autosomal recessive, or X linked for a specific condition. The NUDT13 gene is located on chromosome 16, which is an autosome, so you inherit one copy from each parent.
What does my NUDT13 result mean for my family?
There isn’t yet a broadly confirmed inheritance pattern tied to a specific health condition for NUDT13, though this can become clearer as research develops. If you have a NUDT13 result and want to understand what it could mean for close relatives, a doctor or genetic counselor can help interpret it in the context of your family history.
Genetic information
Genetic testing
How you find out about variants
To look for variants in the NUDT13 gene, a lab usually analyzes DNA from a blood sample, cheek swab, or saliva sample. In simple terms, what genetic testing is and how it works is that the lab reads the gene’s DNA code and checks for changes. Results may show a variant or no relevant change.
When should I consider getting a genetic test?
There is not yet a broadly established, NUDT13-specific reason for genetic testing in routine care. Testing choices are usually based on your personal health and family history, together with a doctor or genetic counselor.
A genetic result is only one part of your health story
A genetic result can provide useful insight, but how much it reveals depends on the condition and the kind of variant involved. Over time, many factors, including lifestyle, environment, age, and medical history, influence how the body functions. For some conditions, particularly those shaped by many genes, genetic information offers context rather than certainty and is most helpful when considered with other parts of care. In other situations, a genetic result can give a clear answer. In areas like medication response, genetic results can also help put individual experiences in context.
Pharmacogenetics
How variants shape your response to medicine
Genetic variation can affect how people respond to medicines. Small differences in a person’s DNA can change how the body breaks down a drug, moves it through the body, or responds at the drug’s target. This helps explain why the same medication may work well for one person, have little effect in another, or cause more side effects in someone else. These differences are common and are one of several factors, along with age, kidney and liver function, and other medicines, that shape treatment response.
What is Pharmacogenetics?
Pharmacogenetics is the area of study that examines how genetic differences affect a person’s response to medications. It focuses on relationships between genes and drugs to help explain why the same treatment can 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 help guide treatment decisions that are more informed and more personalized.

Drugs influenced by the NUDT13 gene
When should I seek medical advice?
There is not yet a broadly confirmed role for this gene in guiding medication choices, so questions about side effects, starting a new medicine, or changes in treatment are best discussed with your doctor.
