The SLC25A28 gene helps move iron into mitochondria, the parts of cells that make energy. This gene plays an important role in helping cells build heme and other iron based parts they need to work normally. If it does not work properly, cells may handle iron poorly, which can disrupt energy production and increase cell stress. Researchers study it most often in the context of mitochondrial health and how the body uses iron.
What is a gene?
A gene is a stretch of DNA that holds instructions your cells use to make molecules or regulate processes in the body. Some genes carry the directions for producing proteins, which are the working parts of cells. Other genes mainly help determine when certain processes happen, where they take place, and how strongly they operate. Taken together, genes affect how the body develops and works, and they can influence how you respond to food, stress, and medications. For a closer look at this subject, you can find more in the LearnHub.
Overview
SLC25A28Gene function
What if the gene works
The SLC25A28 gene helps move iron into mitochondria, the parts of cells that make energy. This supports heme, part of hemoglobin, and other iron related cell functions.
Risk
What if the gene does not work
Changes in the SLC25A28 gene can range from milder to more severe and may reduce iron movement into mitochondria, the cell’s energy centers. This can lower heme production and disrupt how mitochondria make energy.
Treatment
What does that mean for your treatment
No treatment or management approach specific to pathogenic variants in the SLC25A28 gene is currently established in clinical guidelines. The SLC25A28 gene is being studied in cancer and mitochondrial iron research as a possible biomarker or drug target, but this does not currently guide routine care.
Gene function
What if the gene works
The SLC25A28 gene helps your cells move iron into mitochondria, the small structures that make much of a cell’s energy. When it works as expected, iron reaches these structures in a steady, controlled way. This reflects the SLC25A28 gene’s role in mitochondrial iron transport. That iron then supports heme production and other protein systems your cells use every day.
It moves iron into mitochondria in a controlled way. This gives these energy making parts of the cell the iron they need for routine work.
Inside mitochondria, this gene helps supply iron for heme production. Heme is a building block used in hemoglobin and in many enzymes throughout the body.
The imported iron helps cells make iron-sulfur clusters, small parts that many proteins rely on. These proteins support energy production and other steady day-to-day cell tasks.
What is a variant?
A genetic variant is a minor difference in the DNA sequence within a gene. These differences are common and are part of normal human diversity, including variation in appearance, metabolism, and how the body responds to environmental influences. Many variants do not have any noticeable effect and simply reflect natural genetic variation. In some situations, 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 SLC25A28 gene can change the shape, stability, or amount of its mitochondrial iron carrier, which may lower iron movement into mitochondria. The effect of SLC25A28 gene variants on mitochondrial iron transport depends on the type of DNA change: milder variants may partly reduce transport, while more severe variants can markedly impair protein folding, targeting, or activity. This can interfere with how cells make key iron-containing molecules used for energy production and other basic cell work.
How variants are linked to conditions
Variants in the SLC25A28 gene do not yet have a broadly confirmed link to a specific health condition, so information on conditions linked to SLC25A28 gene variants is still evolving. If you have a reported variant in the SLC25A28 gene, your doctor or genetic counselor can interpret it alongside your symptoms, family history, and test results.
A variant is not necessarily a diagnosis
Variants in genes are a usual feature of human biology and are widely seen across the general population. Most do not directly affect health and simply contribute to normal human diversity. With many genes, having a variant associated with a condition points to a possible link, not a definite diagnosis, particularly when several genes and environmental influences play a role. In some situations, though, one 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 SLC25A28 gene. If a change in this gene is found on testing, a doctor or genetic counselor can help explain what it may mean for your personal and family risk.
Inheritance of SLC25A28 variants
There is not yet a broadly confirmed Mendelian inheritance pattern tied to a specific human condition for the SLC25A28 gene, so how variants of the SLC25A28 gene are inherited in relation to disease is still being clarified. The SLC25A28 gene is located on chromosome 10, which is an autosome. That means everyone inherits one copy from each parent, regardless of sex.
What does my SLC25A28 result mean for my family?
There isn't yet a broadly confirmed inheritance pattern tied to a specific health condition for SLC25A28, though this understanding can change as research develops. If you have a specific SLC25A28 result and questions about what it could mean for your family, a doctor or genetic counselor can help explain it in the context of your personal and family history.
Genetic information
Genetic testing
How you find out about variants
To find out whether you carry a variant in the SLC25A28 gene, a lab can analyze DNA from a blood, saliva, or cheek swab sample. This SLC25A28 gene genetic test reads the gene's code and checks for changes that may help explain test findings in the right clinical context.
When should I consider getting a genetic test?
There is not yet a broadly established, SLC25A28-specific reason for genetic testing in routine care. Testing decisions are usually based on your symptoms, family history, and guidance from a doctor or genetic counselor.
A genetic result is only one part of your health story
Genetic results can be informative, but what they reveal varies with the condition and the kind of variant involved. How the body works over time is also shaped by many other factors, including lifestyle, environment, age, and medical history. For some conditions, especially those influenced 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 may offer a clear answer. In areas like medication response, genetic results can 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 absorbs, breaks down, transports, or reacts to a drug. This helps explain why the same treatment may work well for one person, seem less effective for another, or cause more side effects in someone who is more sensitive to it.
What is Pharmacogenetics?
Pharmacogenetics examines how genetic differences can shape a person’s response to medications. It studies gene and drug patterns to help explain why the same treatment may work differently from one person to another. For many medicines, genes affect either how strongly a drug works or how the body processes it. This information can support treatment decisions that are more informed and more individualized.

Drugs influenced by the SLC25A28 gene
When should I seek medical advice?
There is not yet a broadly confirmed role for this gene in guiding medication choices. If you have concerns about side effects, a medicine not working as expected, or how your health history may affect treatment, discuss it with your doctor.
