The NME1 gene helps cells manage energy and make the small building blocks needed for DNA and other basic cell tasks. This gene plays an important role in how cells grow, move, and repair damage. If the NME1 gene does not work well, cells may be less able to control these processes, which can contribute to tumor growth or spread in some cancers. NME1 is mainly known in medical research rather than public culture.
What is a gene?
Genes are stretches of DNA that carry instructions cells use to make molecules or to regulate activities in the body. Some genes provide the directions for producing proteins, which are the functional parts of cells. Others mainly guide when certain processes happen, where they take place, and how active they are. Taken together, genes affect how the body grows and works, and they can influence how you respond to food, stress, or medicines.

Overview
NME1Gene function
What if the gene works
The NME1 gene helps cells maintain balanced supplies of the small molecules used to make DNA and RNA. It also supports normal cell signaling, growth, and movement.
Risk
What if the gene does not work
When the NME1 gene works less well, cells may struggle to recycle nucleotide building blocks and regulate growth and movement signals. Milder variants may partly reduce this activity, while more severe variants can disrupt it more clearly.
Treatment
What does that mean for your treatment
No treatment or management approach is currently established specifically for pathogenic or loss-of-function variants in the NME1 gene. The NME1 gene is mainly being studied as a biomarker and possible drug target in cancer research, especially in relation to tumor spread.
Gene function
What if the gene works
Your cells need a steady supply of chemical building blocks to copy DNA, make RNA, and pass messages. The NME1 gene helps keep these molecules balanced by making a protein that moves phosphate groups between them. Understanding what the NME1 gene does in your cells makes its role in everyday cell work easier to see.
Inside your cells, the NME1 gene makes a protein that passes phosphate groups from one small molecule to another. This lets cells quickly convert building block molecules into the forms they need at the time.
The NME1 gene helps maintain balanced supplies of molecules used to make DNA and RNA. This steady supply supports routine jobs such as cell growth, cell division, and protein production.
Many signals inside cells depend on GTP, a small energy carrying molecule. By helping replenish GTP, the NME1 gene supports communication inside cells and the timing of everyday cell activity.
What is a variant?
A genetic variant is a small difference in the DNA sequence of a gene. These differences are common and help shape normal human diversity, such as variation in appearance, metabolism, or how the body responds to environmental influences. Many variants do not have any noticeable effect and are simply part of natural genetic variation. In some situations, though, a variant can change how a gene works to a greater extent and may contribute to, or cause, a genetic condition.
Genetic variants
What if the gene does not work
Variants in the NME1 gene can change the protein’s shape, stability, or activity, which helps explain how NME1 gene variants affect protein activity at the cell level. Some missense variants change a single building block and may partly weaken folding, reduce enzyme activity, or disrupt how the protein joins with partner proteins. More severe loss of function variants can sharply lower or abolish activity, often leading to a larger functional effect than milder variants.
How variants are linked to conditions
Health conditions linked to NME1 gene variants are not yet broadly confirmed, and interpretations can change as research develops. If you have a reported variant in the NME1 gene, your doctor or genetic counselor can explain what it may mean for you based on your symptoms, family history, and updated evidence.
A variant is not necessarily a diagnosis
Genetic variants are a routine part of human biology and are widely found in the general population. Most do not have a direct effect on health and instead reflect natural variation among people. For many genes, carrying a variant associated with a condition suggests a possible link rather than a confirmed diagnosis, especially when more than one gene and environmental factors are involved. In some situations, however, 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 is not yet broadly confirmed evidence on specific factors that increase or reduce health risk related to the NME1 gene. Anyone concerned about personal or family risk can discuss it with a doctor or genetic counselor.
Inheritance of NME1 variants
There is not yet a broadly confirmed, disease-specific Mendelian pattern for how NME1 variants are inherited. Current evidence has not established one clear mode, such as autosomal dominant or autosomal recessive, for NME1-related disease, so the answer to how NME1 variants are inherited remains cautious and research-based. The NME1 gene is located on chromosome 17, which is an autosome, so you inherit one copy from each parent.
What does my NME1 result mean for my family?
There is not yet a broadly confirmed inheritance pattern tied to a specific well-established condition for NME1. If you have a specific NME1 result and want to understand what it could mean for your relatives, a doctor or genetic counselor can explain it in the context of your exact result and family history.
Genetic information
Genetic testing
How you find out about variants
Genetic testing for variants in the NME1 gene reads the DNA code in a blood or saliva sample and checks for changes. Results may show a benign variant, a variant of uncertain significance, or a pathogenic variant, depending on what is found.
When should I consider getting a genetic test?
There is not yet a broadly established reason to order genetic testing just for the NME1 gene. Testing decisions are usually based on your personal health history, family history, and whether a doctor or genetic counselor thinks a broader gene test would be more helpful.
A genetic result is only one part of your health story
A genetic result can be informative, but how much it explains varies by the condition and the kind of variant involved. Over time, many factors, including lifestyle, environment, age, and medical history, influence how the body functions. In some conditions, especially those shaped by many genes, genetic information provides context rather than certainty and is most useful when viewed alongside 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 experiences into context.
Pharmacogenetics
How variants shape your response to medicine
Genetic variation can affect how your body breaks down, moves, and responds to medicines. That helps explain why the same medication may work well for one person, cause more side effects in another, or have less effect in someone else. These differences are common and can influence both how well a treatment works and how sensitive a person is to it. Genes are only one part of the picture, alongside age, liver and kidney function, other health conditions, and other medicines.
What is Pharmacogenetics?
Pharmacogenetics is the area of study that examines how differences in genes affect the way people respond to medicines. It focuses on gene-drug patterns to help explain why the same treatment can work differently from one person to another. With many medications, genes influence both how strong a drug’s effect is and how the body handles it. This information can support treatment decisions that are more informed and more individualized.

Drugs influenced by the NME1 gene
When should I seek medical advice?
There is not yet a broadly confirmed role for this gene in guiding medication choice or predicting how well a medicine will work. Questions about medicines, side effects, or your overall health are best discussed with your doctor.
History
The NME1 gene gained scientific attention in the late 1980s, when researchers studying melanoma found that lower NME1 activity was linked to a greater chance that cancer would spread. From these first observations, research expanded steadily. This made the NME1 gene the first widely recognized metastasis suppressor gene, an important milestone in cancer genetics. Early work was led by Patricia Steeg and colleagues, whose studies helped shift cancer research beyond tumor growth alone to the biology of spread. In the years that followed, NME1 was examined in several cancer types, including breast cancer and melanoma. Its discovery helped open a new field focused on why some cancers stay localized while others move to distant parts of the body.
