The SLC25A6 gene helps mitochondria, the parts of cells that make energy, swap used energy molecules for fresh ones so cells can keep working. Every cell in your body uses this gene to support basic tasks such as growth, movement, and organ function. If the gene does not work properly, cells may struggle to manage energy, which can contribute to developmental differences and problems in tissues that need a lot of energy, including the brain, muscles, and heart.
What is a gene?
Genes are sections of DNA that give your cells instructions to make molecules or regulate processes in the body. Some genes hold the code for proteins, the parts of cells that do much of the work. Others mainly control when certain processes happen, where they happen, and how active they are. Together, genes affect how the body develops and works, and they can influence how you respond to food, stress, and medications.

Overview
SLC25A6Gene function
What if the gene works
The SLC25A6 gene helps shuttle energy molecules in and out of mitochondria, your cells’ energy centers. This exchange supports a steady energy supply for everyday cell tasks.
Risk
What if the gene does not work
Milder to more severe variants in the SLC25A6 gene can reduce how well mitochondria swap ADP for ATP, helping move usable energy around cells. This may weaken cellular energy supply and can disrupt mitochondrial function to different degrees.
Treatment
What does that mean for your treatment
No SLC25A6-specific treatment or management approach is currently established for pathogenic or loss-of-function variants in the SLC25A6 gene. The SLC25A6 gene is being studied in mitochondrial medicine and cancer research because it affects cell energy handling and programmed cell death, but this has not yet changed routine drug choices.
Gene function
What if the gene works
Your cells need a steady energy supply for every heartbeat, muscle movement, and nerve signal. The SLC25A6 gene helps keep that supply moving inside mitochondria, the parts of cells that make most ATP, the cell’s main energy source. This supports routine activity across many tissues.
Inside the inner membrane of mitochondria, this gene’s protein swaps ATP made in mitochondria for ADP from the rest of the cell. That exchange is a central step in making mitochondrial energy available throughout the cell.
After mitochondria produce ATP, the SLC25A6 gene helps move it out to places in the cell where energy is needed. This helps power everyday jobs like muscle contraction, nerve signaling, and moving substances across cell membranes.
When ATP is used, it becomes ADP and needs to return to mitochondria to be recharged. By bringing ADP back in, this gene supports a continuous cycle of cellular energy use and renewal.
What is a variant?
A genetic variant is a minor change in a gene’s DNA sequence. Variants are common and help explain normal human diversity, including differences in appearance, metabolism, and how the body responds to environmental influences. Many have no noticeable effect and are simply part of natural genetic variation. Sometimes, however, a variant can affect how a gene functions more substantially and may contribute to or cause a genetic condition.
Genetic variants
What if the gene does not work
Changes in the SLC25A6 gene can alter the protein's shape or stability, so mitochondria exchange ATP and ADP less effectively. In practical terms, this is how SLC25A6 gene variants affect cell energy handling. Milder missense variants may leave some transport activity, while more disruptive variants can greatly reduce transport or prevent the protein from settling into the inner mitochondrial membrane, and these stronger effects are often linked to earlier and more severe mitochondrial disease.
How variants are linked to conditions
At this time, the SLC25A6 gene does not yet have a broadly confirmed link to a specific health condition, although research on SLC25A6 gene variants linked to conditions is still evolving. Anyone with a confirmed SLC25A6-related diagnosis should rely on guidance from their doctor or genetic counselor for interpretation that fits their own results and health 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 impact on health and simply contribute to natural 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 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 isn't yet broadly confirmed evidence on specific factors that increase or reduce health risk related to the SLC25A6 gene. In families with a harmful change in SLC25A6, the main factor is whether that gene change is present, while symptoms can still vary from person to person.
Inheritance of SLC25A6 variants
There is not yet a broadly confirmed inheritance pattern tied to a specific SLC25A6-related condition, so how SLC25A6 gene variants are inherited in families is still being clarified. SLC25A6 is located on the X chromosome, which means inheritance can differ between sons and daughters. A child receives an X chromosome from each parent if female and one X chromosome from the mother if male, so any inherited SLC25A6 variant would follow X-linked transmission rather than an autosomal dominant or autosomal recessive pattern.
What does my SLC25A6 result mean for my family?
There isn't yet a broadly confirmed inheritance pattern tied to a specific condition for SLC25A6, though this understanding can change as research develops. If you have a specific SLC25A6 result and questions about what it could mean for your family, a doctor or genetic counselor can give guidance tailored to your situation.
Genetic information
Genetic testing
How you find out about variants
To look for changes in the SLC25A6 gene, genetic testing for SLC25A6 variants usually uses a blood or saliva sample. A lab reads the DNA sequence and compares it with the usual version to identify variants that may help confirm or clarify a diagnosis.
When should I consider getting a genetic test?
There is not yet a broadly established reason to test SLC25A6 on its own. It may be included in broader genetic testing when someone has signs of a condition that affects how cells make energy, such as muscle weakness, heart problems, or developmental delay. Testing decisions are best made with a doctor or genetic counselor.
A genetic result is only one part of your health story
A genetic result can be informative, but the amount it reveals varies with the condition and the kind of variant identified. Over time, many factors, including lifestyle, environment, age, and medical history, influence how the body functions. With some conditions, particularly those shaped by many genes, genetic information offers context rather than certainty and makes the most sense when considered with other parts of care. In other situations, a genetic result may give a clear answer. For topics like medication response, genetic results can also help put personal experiences into context.
Pharmacogenetics
How variants shape your response to medicine
Genetic variation can affect how your body responds to medicines. This helps explain why the same treatment works well for one person, causes side effects in another, or seems to have little effect for someone else. Common differences in how the body absorbs, breaks down, transports, or responds to a drug can influence both benefit and sensitivity.
What is Pharmacogenetics?
Pharmacogenetics examines how genetic differences shape a person’s response to medications. By looking at connections between genes and drugs, it helps explain why the same treatment may work differently from one person to another. For many medicines, genes can affect both how strongly a drug works and how the body handles it. This information can support treatment decisions that are more informed and more individualized.

Drugs influenced by the SLC25A6 gene
When should I seek medical advice?
There is not yet a broadly confirmed role for this gene in guiding medication choices, so general concerns about medicines, side effects, or new symptoms are best discussed with your doctor. Seek medical advice promptly if you have a strong reaction after starting a new medicine, your treatment is not working as expected, or you are taking several medicines at once.
