The SLC22A31 gene belongs to a family of genes that helps move small molecules across cell membranes. This gene plays an important role in how cells handle certain substances from their surroundings. If the gene does not work as expected, those transport steps may become less efficient, which can affect how cells function. At this stage, SLC22A31 is mainly of research interest rather than a gene widely linked to a well-known inherited condition.
What is a gene?
A gene is a stretch of DNA that carries instructions your cells use to make molecules or direct activities in the body. Some genes provide the directions for building proteins, which are the working parts of cells. Other genes mainly regulate when certain processes happen, where they happen, and how strongly they are turned on. Together, genes affect how the body develops and works, and they can influence how you respond to food, stress, or medications. To explore this topic further, you can find more in the LearnHub.
Overview
SLC22A31Gene function
What if the gene works
The SLC22A31 gene helps make a transport protein in cell membranes. This protein family moves small charged molecules into and out of cells, supporting normal cell balance.
Risk
What if the gene does not work
Changes in the SLC22A31 gene may alter how its cell transport protein is made or works. Milder variants may have little effect, while more severe variants can reduce or stop normal movement of substances across cell membranes.
Treatment
What does that mean for your treatment
No treatment or management approach is currently established specifically for pathogenic or loss-of-function variants in the SLC22A31 gene.
Gene function
What if the gene works
Your cells use the SLC22A31 gene to make a protein in the solute carrier family. Proteins in this family help move selected substances across cell membranes, which supports a steady internal environment. This gives a practical picture of what the SLC22A31 gene does in the body.
The SLC22A31 gene belongs to a group of genes that make transport proteins. These proteins help move small molecules across the cell membrane in a controlled way.
By supporting the movement of substances into and out of cells, the SLC22A31 gene helps cells keep their internal chemistry steady. This supports routine cell activity across the body.
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 variations in appearance, metabolism, and the way the body reacts to environmental influences. Many do not have any noticeable effect and simply represent natural genetic variation. In some situations, though, a variant can change how a gene works more significantly and may contribute to or cause a genetic condition.
Genetic variants
What if the gene does not work
Changes in the SLC22A31 gene may affect how much protein a cell makes, how stably the protein folds, and whether it reaches the cell surface. This is one way SLC22A31 gene variants affect protein function, with milder variants sometimes causing partial loss of activity and more disruptive variants markedly reducing or abolishing it. Some variants may also change how the protein interacts with other cell components, which can further lower its stability or transport activity.
How variants are linked to conditions
Current evidence has not broadly confirmed a specific disease association for the SLC22A31 gene, so information about how SLC22A31 gene variants are linked to conditions is still evolving. If you have a reported variant in this gene, your doctor or genetic counselor can interpret it in the context of your health and family history.
A variant is not necessarily a diagnosis
Gene variants are a usual part of human biology and are widely seen in the general population. Most do not directly affect health and simply add to natural human variation. For many genes, carrying a variant associated with a condition indicates a possible link rather than a certain diagnosis, especially when several genes and environmental factors also play a role. In some situations, though, a single well-defined variant in a particular gene is enough to confirm a diagnosis.
Are there things that can increase or change my risk?
There is not yet broadly confirmed evidence that specific lifestyle, environmental, or family factors clearly increase or lower health risk related to SLC22A31. Anyone concerned about what this gene may mean for their personal or family risk should speak with a doctor or genetic counselor.
Inheritance of SLC22A31 variants
There is not yet a broadly confirmed disease specific inheritance pattern for the SLC22A31 gene, so SLC22A31 gene inheritance is not described as a well established autosomal dominant, autosomal recessive, or X linked condition at this time. The SLC22A31 gene is located on an autosome rather than a sex chromosome, which means each person inherits one copy from each parent.
What does my SLC22A31 result mean for my family?
There is not yet a broadly confirmed inheritance pattern tied to a specific health condition for the SLC22A31 gene, and this picture may become clearer as research grows. If you have a specific SLC22A31 result and want to understand what it could mean for relatives, a doctor or genetic counselor can explain it in the context of your family history and the exact result.
Genetic information
Genetic testing
How you find out about variants
A genetic test can look for SLC22A31 variants by reading the DNA sequence from a blood sample, saliva sample, or cheek swab. In practice, genetic testing for SLC22A31 variants is often done as part of a broader gene panel or exome test, and the lab compares your sequence with a reference to identify changes.
When should I consider getting a genetic test?
There isn't yet a broadly established, SLC22A31-specific clinical reason for testing. Testing decisions are best made with a doctor or genetic counselor based on your health concerns and family history.
A genetic result is only one part of your health story
Genetic results can provide useful insight, but how much they reveal depends on the condition and the kind of variant involved. Lifestyle, environment, age, and medical history are among the many factors that shape how the body works over time. For some conditions, especially those influenced by many genes, genetic information offers context rather than certainty and is best understood 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 into perspective.
Pharmacogenetics
How variants shape your response to medicine
Genetic variation can affect how people respond to medicines. Small inherited differences can change how the body absorbs, breaks down, moves, or responds to a drug. This helps explain why the same treatment may work well for one person, have less effect in another, or cause more side effects in someone else. These differences are common and are one part of the bigger picture, along with age, kidney and liver function, other health conditions, and other medicines.
What is Pharmacogenetics?
Pharmacogenetics is the area of study that examines how genetic differences affect the way people respond to medications. It looks at patterns between genes and drugs to help explain why the same treatment may work differently from one person to another. For many medications, genes influence how strongly a drug acts or how the body processes it. This information can support more informed and more individualized treatment decisions.

Drugs influenced by the SLC22A31 gene
When should I seek medical advice?
There is not yet a broadly confirmed role for this gene in predicting medication response, so general medication or health concerns are best discussed with your doctor.
