The SLC22A23 gene belongs to a family of genes involved in moving small molecules into and out of cells. The protein made by this gene helps your cells handle certain substances across the cell membrane, which supports normal tissue function. If it does not work as expected, cells may manage these molecules less efficiently, and that can affect how some tissues work. Unlike genes such as BRCA1 or APOE, the SLC22A23 gene is not widely known outside research and clinical genetics.
What is a gene?
Genes are stretches of DNA that give your cells instructions for making molecules or for guiding activities in the body. Some genes provide the directions for producing proteins, which do much of the work inside cells. Other genes mainly regulate when certain processes happen, where they take place, and how active they are. Together, genes affect how the body develops and works, and they can influence how you respond to food, stress, or medications.

Overview
SLC22A23Gene function
What if the gene works
The SLC22A23 gene makes a transport protein that likely helps move small molecules across cell membranes. It may support routine transport work in several tissues.
Risk
What if the gene does not work
Changes in the SLC22A23 gene can range from milder to more severe variants, which may reduce how well its transporter protein works. This can alter movement of certain small molecules across cell membranes and affect normal cell handling of them.
Treatment
What does that mean for your treatment
No SLC22A23-specific treatment or management approach is currently established in clinical guidelines for people with a pathogenic or loss-of-function variant in the SLC22A23 gene.
Gene function
What if the gene works
Your cells constantly move nutrients, waste products, and signaling chemicals across their outer membrane. The SLC22A23 gene helps make a transport protein involved in that traffic. Understanding how the SLC22A23 gene works helps explain how cells move substances across cell membranes and keep their internal environment steady.
The SLC22A23 gene belongs to a family that helps cells move small molecules across their membranes. Its protein takes part in the controlled flow of substances into and out of the cell.
By helping manage this traffic, the SLC22A23 gene supports the chemical balance cells need for daily activity. This steady exchange helps cells take up useful compounds and move other substances back out.
What is a variant?
A genetic variant is a small change in the DNA sequence within a gene. These changes are common and are part of normal human diversity, such as differences in appearance, metabolism, or the way the body responds to environmental influences. Many variants do not have any noticeable effect and simply represent natural genetic variation. In some situations, however, a variant can change a gene’s function more substantially and may contribute to or cause a genetic condition.
Genetic variants
What if the gene does not work
Variants in the SLC22A23 gene can change the shape or amount of its transporter protein, which may affect folding, stability, movement to the cell membrane, or transport activity. How SLC22A23 gene variants affect protein function often depends on the type of DNA change. Milder variants may partly reduce activity, while more severe variants can greatly lower protein stability, disrupt RNA splicing, or stop the protein from being made.
How variants are linked to conditions
The SLC22A23 gene does not yet have a broadly confirmed link to a specific health condition, although research on SLC22A23 gene disease association is still developing. If you have a reported variant in the SLC22A23 gene, it is best interpreted in the context of your own medical history and family history with a doctor or genetic counselor.
A variant is not necessarily a diagnosis
Genetic variants are common across the general population and are a normal feature of human biology. Most do not directly affect health and instead reflect the natural variation seen among people. For many genes, having a variant associated with a condition points to a possible link, not a certain diagnosis, particularly when several genes and environmental influences also play a role. There are cases, though, where one well-characterized 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 on specific factors that increase or reduce health risk related to the SLC22A23 gene. If you have questions about your own risk or a family history of similar health problems, a doctor or genetic counselor can help put genetic results in context.
Inheritance of SLC22A23 variants
There is not yet a broadly confirmed Mendelian pattern for how variants of the SLC22A23 gene are inherited in relation to a specific human condition, so the answer to how variants of the SLC22A23 gene are inherited remains cautious and may evolve as research develops. The SLC22A23 gene is located on chromosome 6, which is an autosome. That means each person inherits one copy from each parent, regardless of sex.
What does my SLC22A23 result mean for my family?
There isn't yet a broadly confirmed inheritance pattern tied to a specific health condition for SLC22A23, though this understanding can change as research develops. If you have a specific SLC22A23 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 family history and health.
Genetic information
Genetic testing
How you find out about variants
To look for changes in the SLC22A23 gene, genetic testing reads DNA from blood or saliva. For people asking how to test for SLC22A23 variants, labs usually sequence the gene in a multigene panel, exome, or genome test and report whether a variant was found, including uncertain findings.
When should I consider getting a genetic test?
There is not yet a broadly established, SLC22A23-specific clinical reason for genetic testing. Testing choices are best made with a doctor or genetic counselor, based on your symptoms, medical history, and family history.
A genetic result is only one part of your health story
A genetic result can be useful, but how much it explains depends on the condition and on the kind of variant involved. How the body functions over time is also shaped by many factors, including lifestyle, environment, age, and medical history. For some conditions, especially those affected by many genes, genetic information provides context rather than certainty and is most useful when considered alongside other parts of care. In other situations, a genetic result may offer a clear answer. In 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 your body responds to medicines. Small differences in DNA can change how quickly a drug is absorbed, broken down, moved through the body, or how strongly it acts at its target. This helps explain why the same medication may work well for one person, cause more side effects in another, or seem less effective in someone else.
What is Pharmacogenetics?
Pharmacogenetics examines how differences in a person’s genes can affect the way they respond to medications. It studies gene and drug patterns to help explain why the same treatment may work differently from one person to another. With many medicines, genes can influence how the body handles a drug or how strong its effects are. This information can support treatment choices that are more informed and more tailored to the individual. More detailed information on this topic is available in the LearnHub.
Drugs influenced by the SLC22A23 gene
When should I seek medical advice?
There is not yet a broadly confirmed role for this gene in guiding medicine choices, so questions about side effects, new symptoms, or whether a treatment is working are best discussed with your doctor.
History
SLC22A23 entered the scientific literature during the era when large DNA sequencing projects were mapping and naming many human genes. In recent decades, awareness of this gene’s role has grown mainly through genome annotation studies, which placed it within the SLC22 family of transport related genes. Early work focused on identifying its DNA sequence, where it is located in the genome, and how its activity differs across tissues. From these first observations, research expanded steadily, with later studies exploring whether variants in the SLC22A23 gene might be linked to differences in health traits and treatment response. Its history is part of the broader shift from simply cataloging genes to studying how individual genetic differences may shape human biology.
