The SLC25A39 gene helps move glutathione, one of the cell’s main protective molecules, into mitochondria, the parts of cells that make energy. This gene plays an important role in helping cells handle everyday stress and support healthy red blood cell production. If the SLC25A39 gene does not work properly, mitochondria may be less protected, and people with harmful variants in both copies can develop anemia and other signs of mitochondrial disease.
What is a gene?
Genes are stretches of DNA that hold instructions your cells use to make molecules or manage processes throughout the body. Some carry the directions for producing proteins, which are the parts of cells that do much of the work. Others mainly help regulate 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 also influence how you respond to food, stress, and medications.

Overview
SLC25A39Gene function
What if the gene works
The SLC25A39 gene helps move glutathione, a key protective molecule, into mitochondria. This supports energy production and helps cells manage oxidative stress.
Risk
What if the gene does not work
Milder to more severe variants in the SLC25A39 gene can reduce glutathione import into mitochondria, the parts of cells that handle energy. This may disrupt the cell steps needed to make hemoglobin and other cell energy processes.
Treatment
What does that mean for your treatment
No treatment or management approach specifically tied to pathogenic variants in the SLC25A39 gene is currently established in clinical guidelines. The SLC25A39 gene is being studied in early-stage research because it helps control glutathione levels inside mitochondria, which may support future biomarker or drug-target work.
Gene function
What if the gene works
Understanding what the SLC25A39 gene does starts inside mitochondria, the parts of your cells that help make energy. This gene helps move an important protective molecule called glutathione into those structures, supporting steady day to day cell activity.
The SLC25A39 gene makes a transporter that moves glutathione into mitochondria, the parts of cells that help make energy. This places glutathione where cells need it for routine work.
Glutathione helps control oxidative stress, which is wear and tear from normal cell activity. By supplying mitochondria with glutathione, the SLC25A39 gene supports a balanced internal cell environment.
Mitochondria use glutathione while making iron sulfur clusters (tiny iron containing parts that help many proteins work). By delivering glutathione into mitochondria, the SLC25A39 gene supports this basic cell process.
What is a variant?
A genetic variant is a minor change in the DNA sequence within a gene. These changes are common and are part of normal human diversity, including differences in appearance, metabolism, and the way the body reacts to environmental factors. Many variants do not have any noticeable effect and are simply part of natural genetic variation. Sometimes, though, a variant changes how a gene works to a greater extent and can contribute to or cause a genetic condition.
Genetic variants
What if the gene does not work
Variants in the SLC25A39 gene can reduce or disrupt a protein that helps move glutathione, a key cell protector, into mitochondria (the cell’s energy compartments). This is how SLC25A39 variants affect cell function: less glutathione reaches mitochondria, which can weaken protein stability and other chemical processes inside the cell. Milder variants may leave some transport activity, while more severe variants can cause little or none. In general, the less activity that remains, the larger the cellular effect.
How variants are linked to conditions
The SLC25A39 gene does not yet have a broadly confirmed link to a specific health condition in routine clinical genetics, though research on how SLC25A39 gene variants may relate to health conditions is still developing. Anyone with a confirmed SLC25A39-related diagnosis should rely on guidance from their doctor or genetic counselor rather than general information.
A variant is not necessarily a diagnosis
Genetic variants are a routine part of human biology and are common throughout the general population. Most do not directly affect 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 certain diagnosis, especially when multiple genes and environmental factors are involved. In some situations, though, a single well-characterized variant in a specific 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 SLC25A39 gene. If a change in SLC25A39 is found on genetic testing, a doctor or genetic counselor can help explain what it may mean for your personal and family risk.
Inheritance of SLC25A39 variants
There is not yet a broadly confirmed, single disease inheritance pattern for the SLC25A39 gene that is used routinely in patient care, so how SLC25A39 gene variants are inherited is still being clarified as research develops. The SLC25A39 gene is located on chromosome 17, which is an autosome. That means you inherit one copy of the gene from your mother and one copy from your father.
What does my SLC25A39 result mean for my family?
There is not yet a broadly confirmed, condition-specific inheritance pattern for SLC25A39 that is used routinely in patient care, and this understanding can change as research grows. If you have a specific SLC25A39 result and want to know what it could mean for parents, children, brothers, sisters, or future pregnancies, a genetics specialist can explain it in the context of your exact finding.
Genetic information
Genetic testing
How you find out about variants
To find out about variants in the SLC25A39 gene, genetic testing uses a blood or saliva sample to read the gene’s DNA. SLC25A39 genetic testing may be done as a single gene test or included in a broader multigene panel, exome, or genome test.
When should I consider getting a genetic test?
There isn’t yet a broadly established SLC25A39-specific reason for genetic testing in routine care. Testing decisions are usually guided by your symptoms, family history, and a doctor’s or genetic counselor’s judgment, especially when a rare inherited condition is being considered.
A genetic result is only one part of your health story
A genetic result can provide useful insight, but how much it reveals varies by the condition and the specific type of variant. Over time, body function is also shaped by many factors, including lifestyle, environment, age, and medical history. For some conditions, particularly those affected by many genes, genetic information offers context rather than certainty and is most helpful when viewed alongside other parts of care. In other situations, a genetic result may 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 your body responds to medicines. This helps explain why the same treatment works well for one person, seems weaker for another, or causes more side effects in someone else. Part of the difference comes from how quickly the body absorbs, breaks down, moves, or clears a drug. These differences are common and can influence both how well a medicine works and how sensitive you may be to it.
What is Pharmacogenetics?
Pharmacogenetics examines how genetic differences can affect a person’s response to medications. It looks at relationships between genes and drugs to help explain why the same treatment works differently from one person to another. For many medicines, genes can influence how strongly a drug works or how the body handles it. This information can support more informed, individualized treatment decisions. You can read more about this topic in the LearnHub.
Drugs influenced by the SLC25A39 gene
When should I seek medical advice?
There is not yet a broadly confirmed role for this gene in predicting how medicines will work, so questions about treatments, side effects, or changes in your health are best discussed with your doctor.
