The SLC27A3 gene helps cells take in and prepare certain long chain fatty acids, which are fats your body uses for energy, growth, and building cell membranes. This gene plays an important role in how tissues handle fat during normal development and everyday cell work. If it does not work properly, cells may process these fats less efficiently, which can disturb normal tissue function. The SLC27A3 gene is mainly known in genetics and research rather than in everyday public health discussions.
What is a gene?
Genes are sections of DNA that carry instructions your cells use to make molecules or regulate processes in the body. Some genes provide the information needed to produce proteins, the parts of cells that do the work. Other genes mainly help direct when certain processes happen, where they take place, and how strongly they occur. Together, genes affect how the body develops and functions, and they can also influence how you respond to food, stress, or medications.

Overview
SLC27A3Gene function
What if the gene works
The SLC27A3 gene helps cells take in certain fatty acids and prepare them for use. This supports energy production and the building of cell membranes.
Risk
What if the gene does not work
Milder to more severe variants in the SLC27A3 gene can reduce how well cells take up and activate long-chain fatty acids. This may weaken normal fat handling in cell membranes and energy use.
Treatment
What does that mean for your treatment
No treatment or management approach tied specifically to a pathogenic or loss-of-function variant in the SLC27A3 gene is currently established. The SLC27A3 gene is being studied in lipid metabolism and in some cancer research, but this has not led to guideline-based drug choices.
Gene function
What if the gene works
Your cells need a steady supply of fats to build membranes and manage energy. The SLC27A3 gene helps move certain fatty acids into cells and prepares them for use. This supports everyday cell work, including making membranes and handling stored fuel.
The SLC27A3 gene helps cells take up long-chain fatty acids from their surroundings. These fats become available for everyday tasks such as making membranes and storing or using fuel.
Inside cells, the SLC27A3 gene helps attach coenzyme A (a small helper molecule) to certain fatty acids. This activates the fats so they can be moved, stored, or broken down in a controlled way.
By preparing fatty acids for use, this gene supports the supply of lipid building blocks that cells need. These building blocks help make cell membranes and other fats used in routine cell function.
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 responds to environmental influences. Many variants do not produce any noticeable effect and simply represent natural genetic variation. In some situations, though, a variant changes how a gene works more significantly and can contribute to or directly cause a genetic condition.
Genetic variants
What if the gene does not work
Variants in the SLC27A3 gene can change the FATP3 protein's shape, stability, or placement in the cell, which may weaken long-chain fatty acid handling. In studies of how SLC27A3 gene variants affect protein function, some missense variants seem to partly reduce activity, while splice or truncating variants can lead to very little or no working protein. This range from milder to more severe variants can influence how much function remains at the cellular level.
How variants are linked to conditions
Current evidence shows that the SLC27A3 gene does not yet have a broadly confirmed link to a specific health condition, so information on how variants in the SLC27A3 gene are linked to conditions is still evolving. Anyone with a confirmed SLC27A3 variant should rely on guidance from their doctor or genetic counselor for personal interpretation.
A variant is not necessarily a diagnosis
Variants in genes are a routine feature of human biology and are widespread across the population. Most do not directly affect health and simply reflect normal human diversity. For many genes, a variant associated with a condition points to a possible link rather than a certain diagnosis, particularly when several genes and environmental influences play a role. In some situations, though, one well understood variant in a particular gene is enough to establish 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 SLC27A3 gene. If testing finds a change in SLC27A3, a doctor or genetic counselor can help explain what it may mean in the context of your personal and family history.
Inheritance of SLC27A3 variants
There is not yet a broadly confirmed Mendelian pattern for inheritance of the SLC27A3 gene variants tied to a specific human condition, and this picture may become clearer as research grows. For families asking about the inheritance of the SLC27A3 gene variants, the key point is that SLC27A3 sits on chromosome 1, which is an autosome. That means each person inherits one copy of the SLC27A3 gene from each parent.
What does my SLC27A3 result mean for my family?
There is not yet a broadly confirmed inheritance pattern tied to a specific health condition for the SLC27A3 gene, and this understanding may change as research grows. If you have a specific SLC27A3 result and want to know what it could mean for relatives, a doctor or genetic counselor can help interpret it in the context of your family history.
Genetic information
Genetic testing
How you find out about variants
To find out about variants in the SLC27A3 gene, genetic testing uses DNA from a blood or saliva sample. A lab reads the gene's sequence, often through a multigene panel, exome test, or whole genome test, and compares it with the usual sequence. Results may identify a benign variant, a pathogenic variant, or an uncertain finding.
When should I consider getting a genetic test?
There is not yet a widely accepted, SLC27A3-specific reason for genetic testing in routine care. Testing is usually considered based on your own health history, family history, and the broader question a doctor or genetic counselor is trying to answer.
A genetic result is only one part of your health story
A genetic result can provide useful insight, but how much it explains depends on the condition and on the kind of variant involved. Over time, many factors, including lifestyle, environment, age, and medical history, also influence how the body functions. In 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 finding may give a clear answer. For areas 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 people respond to medicines. Small differences in DNA can change how the body absorbs, moves, or breaks down a drug, so the same treatment may work better for one person than for another. This is common and can influence both how much benefit someone gets and how sensitive they are to side effects.
What is Pharmacogenetics?
Pharmacogenetics examines how differences in a person’s genes can shape their response to medicines. It studies patterns between genes and drugs to better explain why the same treatment may work differently from one person to another. For many medications, genes affect both how strongly a drug works and how the body processes it. This information can support more informed and individualized treatment decisions.

Drugs influenced by the SLC27A3 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 any concerns about side effects, medication changes, or new symptoms are best discussed with your doctor.
