The NDRG3 gene helps cells cope with low oxygen and supports normal growth, repair, and the formation of new blood vessels. This gene plays an important role in how your body adapts when tissues are under stress. If it does not work properly, cells may send growth signals in the wrong way, which can affect normal tissue function. Researchers are studying altered NDRG3 activity in several cancers.
What is a gene?
Genes are stretches of DNA that hold instructions your cells use to make molecules or manage activities in the body. Some genes carry the directions for producing proteins, which do much of the work inside cells. Others mostly regulate when certain processes happen, where they happen, and how active they are. In combination, genes affect how the body grows and works, and they can influence how you respond to food, stress, and medicines. For a deeper look at this topic, you can read more in LearnHub.
Overview
NDRG3Gene function
What if the gene works
The NDRG3 gene helps control how cells grow, mature, and respond when oxygen is low. Its protein supports cell signaling, which helps tissues adapt to changing conditions.
Risk
What if the gene does not work
Milder to more severe variants in the NDRG3 gene can reduce how well cells sense and respond to low oxygen. This may disrupt lactate driven growth signaling, affecting cell survival and blood vessel growth at the cellular level.
Treatment
What does that mean for your treatment
No NDRG3-specific treatment or management approach is currently established for people with a pathogenic or loss-of-function variant in the NDRG3 gene. In research, the NDRG3 gene is being studied mainly as a possible cancer biomarker and drug target rather than a guide to current treatment choices.
Gene function
What if the gene works
In your body, the NDRG3 gene supports cell signaling linked to growth and adaptation. Its protein is especially known for helping cells respond when oxygen is limited. Understanding what the NDRG3 gene does in the body helps explain how tissues adjust to changing energy demands.
The NDRG3 gene helps pass messages that tell cells when to grow, move, and stay active. These signals support normal tissue development and everyday cell maintenance.
When oxygen drops, the NDRG3 protein can bind lactate (a normal product of energy use). This helps keep certain cell response pathways running so tissues can adapt to temporary low oxygen.
By supporting these pathways, NDRG3 contributes to normal changes in blood vessel growth and tissue activity when demand rises. This helps the body better match oxygen delivery to what cells need.
What is a variant?
A genetic variant is a minor change in the DNA sequence of a gene. These changes are common and help explain normal differences among people, including appearance, metabolism, and the way the body responds to environmental influences. Many variants have no noticeable effect and are simply part of natural genetic variation. Sometimes, though, a variant changes how a gene works more significantly and may contribute to or cause a genetic condition.
Genetic variants
What if the gene does not work
Variants in the NDRG3 gene can alter the shape, stability, or amount of NDRG3 protein that cells make. In practical terms, how variants influence the NDRG3 gene's function depends on the type of DNA change: some missense variants may only weaken protein folding or partner binding, while more disruptive variants can truncate the protein or sharply reduce its production. This creates a spectrum from milder partial loss of function to more severe loss of function at the cellular level.
How variants are linked to conditions
The NDRG3 gene does not yet have a broadly confirmed link to a specific health condition, although research on NDRG3 gene variants linked to conditions is still developing. If you carry a reported variant in the NDRG3 gene, your doctor or genetic counselor can place that result in context with your personal and family health history.
A variant is not necessarily a diagnosis
Genetic variants are a routine part of human biology and are widely present in the general population. Most do not have a direct effect on health and simply reflect normal human variation. For many genes, having a variant associated with a condition suggests a possible link rather than a definite diagnosis, especially when several genes and environmental factors play a role. In some situations, 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 is not yet broadly confirmed evidence on specific factors that increase or reduce health risk specifically related to the NDRG3 gene. If a change in NDRG3 is found on testing, a doctor or genetic counselor can help explain what it may mean in the context of your personal and family history.
Inheritance of NDRG3 variants
There is not yet a broadly confirmed, disease-specific Mendelian pattern for how NDRG3 gene variants are inherited, so the answer to how NDRG3 variants are inherited is still being clarified as research develops. The NDRG3 gene is located on chromosome 20, which is an autosome. That means each person usually inherits one copy of the NDRG3 gene from their mother and one copy from their father.
What does my NDRG3 result mean for my family?
There is not yet a broadly confirmed inheritance pattern tied to a specific health condition for NDRG3. Understanding of this gene may change as research grows. If you have a specific NDRG3 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 family history.
Genetic information
Genetic testing
How you find out about variants
NDRG3 gene genetic testing uses a blood or saliva sample to read the DNA sequence and look for variants. The lab may study only the NDRG3 gene or include it in a larger panel, then report whether a variant was found and how it is classified.
When should I consider getting a genetic test?
There is not yet a broadly established reason to test for changes in the NDRG3 gene in routine care. Testing is usually guided by your personal health and family history, often with help from 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 explains varies by the condition and the type of variant involved. Over time, many factors, including lifestyle, environment, age, and medical history, influence how the body works. For some conditions, particularly 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 such as medication response, genetic results may 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 absorbs, breaks down, or responds to a drug. 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 why medication response can vary from person to person.
What is Pharmacogenetics?
Pharmacogenetics examines how genetic differences affect the way people respond to medications. It studies links between genes and drugs to help explain why the same treatment can work differently from one person to another. For many medicines, genes influence how strongly a drug works or how the body processes it. This information can support more informed and more individualized treatment decisions.

Drugs influenced by the NDRG3 gene
When should I seek medical advice?
There is not yet a broadly confirmed role for this gene in guiding medication choice or dose, so any concerns about medicines, side effects, or changes in your health are best discussed with your doctor. Research on the NDRG3 gene has mostly focused on how cells react when oxygen is low and how cancers grow, not on routine prescribing.
