The SLC2A10 gene helps cells handle a form of vitamin C and supports the structure of blood vessel walls and other connective tissues. When both copies carry pathogenic variants, it causes arterial tortuosity syndrome, a condition in which arteries can become unusually long, twisted, and more likely to widen. Some people also have stretchy skin, flexible joints, hernias, or differences in facial and skeletal features. SLC2A10 is mainly known in rare disease medicine rather than in everyday public discussion.
What is a gene?
Within DNA, a gene is a stretch that carries information cells use to make molecules or direct processes in the body. Some genes provide instructions for producing proteins, which are the working parts of cells. Others mainly regulate when certain processes happen, where they happen, and how active they are. Taken together, genes affect how the body develops and works, and they can shape how you respond to food, stress, or medications. For a deeper look at this topic, you can read more in the LearnHub.
Overview
SLC2A10Gene function
What if the gene works
The SLC2A10 gene helps move certain sugars and vitamin C within cells. This supports connective tissue and the structure of blood vessel walls.
Risk
What if the gene does not work
Variants in the SLC2A10 gene can cause arterial tortuosity syndrome, which affects connective tissue and may lead to twisted arteries, aneurysms, hernias, and stretchy skin or joints. Milder and more severe variants can influence which features appear and when.
Treatment
What does that mean for your treatment
No SLC2A10-specific treatment or drug selection approach is currently established; care is based on the person’s symptoms and standard management of blood vessel and connective tissue problems.
Conditions associated with SLC2A10
Gene function
What if the gene works
Cells use the SLC2A10 gene to move certain small molecules across membranes. Its transport protein, called GLUT10, is especially important for handling the oxidized form of vitamin C. Understanding how it works can make it easier to see what the SLC2A10 gene does in the body during everyday cell maintenance.
The SLC2A10 gene helps cells move selected small molecules across membranes. Its protein acts as a carrier, bringing these molecules into the cell spaces where they are needed.
One main job is moving dehydroascorbic acid, the oxidized form of vitamin C. Cells can turn it back into vitamin C and use it for routine cell work.
By helping keep vitamin C available in the right places, this gene supports routine cell maintenance. It also helps cells handle everyday wear from oxygen use.
What is a variant?
A genetic variant is a minor difference in the DNA sequence within a gene. These differences are common and help shape normal human diversity, including variation in appearance, metabolism, and the way the body responds to environmental influences. Many variants do not have any noticeable effect and are simply part of natural genetic variation. At times, though, a variant changes how a gene works more significantly and may contribute to, or directly cause, a genetic condition.
Genetic variants
What if the gene does not work
Variants in the SLC2A10 gene can reduce or disrupt the GLUT10 transport protein by changing its shape, making it unstable, or stopping the cell from placing it in the right membrane. This explains how SLC2A10 gene variants affect protein function at a cellular level. Milder variants may leave some transport activity, while more severe variants can lead to little or no working protein. In arterial tortuosity syndrome, lower remaining activity often tracks with earlier or broader features.
How variants are linked to conditions
Pathogenic variants in the SLC2A10 gene cause arterial tortuosity syndrome, a rare inherited condition affecting blood vessels that can also involve the skin, joints, and bones. In SLC2A10 gene and arterial tortuosity syndrome, the diagnosis is typically confirmed when both copies of the gene carry a pathogenic variant. People with this condition may have unusually twisted arteries and related connective tissue features.
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 simply reflect natural differences among people. For many genes, having a variant associated with a condition suggests a possible link rather than providing a definite diagnosis, particularly when several genes and environmental influences also play a part. Still, there are situations in which one well-characterized variant in a particular gene is enough to confirm a diagnosis.
Are there things that can increase or change my risk?
For SLC2A10, risk is mainly shaped by inheritance: people develop the related condition when they inherit a disease-causing change from both parents. There is not broadly confirmed evidence that lifestyle or common environmental factors meaningfully change that underlying genetic risk, although careful medical follow-up can help lower the chance of complications.
Inheritance of SLC2A10 variants
SLC2A10-related arterial tortuosity syndrome follows an autosomal recessive inheritance pattern. This means a child usually inherits one SLC2A10 variant from each parent, and the parents are often healthy carriers. When both parents carry a variant in the SLC2A10 gene, each pregnancy has a 25% chance of producing a child with the condition, a 50% chance of producing a carrier child, and a 25% chance of producing a child with no familial variant. In families asking about the SLC2A10 inheritance pattern, sons and daughters are affected equally.
What does my SLC2A10 result mean for my family?
For families affected by changes in the SLC2A10 gene, close relatives may also carry the same gene change even if they do not have symptoms. Brothers and sisters could be affected or could be carriers, and parents are usually carriers. Other relatives, such as aunts, uncles, and cousins, may also carry the change, so the result can matter beyond one person.
Genetic information
Genetic testing
How you find out about variants
To look for changes in the SLC2A10 gene, clinicians use genetic testing for SLC2A10 variants on a blood or saliva sample. A lab reads the DNA code to check for variants and compares the result with known disease linked and harmless changes. Some results are clear, while others need expert interpretation.
When should I consider getting a genetic test?
Consider testing for changes in the SLC2A10 gene if you or your child has signs of arterial tortuosity syndrome, such as unusually twisted blood vessels, aneurysms, or related connective tissue features. Testing can also help when this condition runs in the family or when a relative is known to carry an SLC2A10 variant.
A genetic result is only one part of your health story
A genetic result can be informative, but how much it reveals depends on the condition and on the type of variant. Over time, many factors, including lifestyle, environment, age, and medical history, also influence how the body functions. For some conditions, particularly those shaped by many genes, genetic information provides context rather than certainty and makes the most sense when considered with other parts of care. In other situations, a genetic result can give a clear answer. In areas like medication response, it 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. The same medication may help one person more, less, or cause more side effects in another because the body can absorb, break down, transport, or respond to drugs differently. These differences are common and can influence how well a treatment works or how sensitive someone is to it.
What is Pharmacogenetics?
Pharmacogenetics examines how differences in a person’s genes can affect the way they respond to medications. It focuses on gene-drug patterns to help explain why the same treatment may work differently in different people. With many medicines, genes can influence how strong a drug’s effects are or how the body processes it. This information can support more informed, personalized treatment decisions. More detail on this topic is available in the LearnHub.
Drugs influenced by the SLC2A10 gene
When should I seek medical advice?
There is not yet a broadly confirmed way for changes in this gene to guide medicine choices or explain medicine side effects. Questions about symptoms, treatment, or any new or changing medication are best discussed with your doctor.
History
SLC2A10 entered medical genetics through work on arterial tortuosity syndrome, a rare inherited condition that had first been recognized from its physical features and blood vessel changes. In 2006, researchers identified variants in the SLC2A10 gene as the cause in affected families, giving the condition a clear genetic basis. This was an important step because it linked scattered case reports into one defined diagnosis. From these first observations, research expanded steadily. Scientists then compared families from different countries and confirmed that changes in the same gene were responsible in many cases. That discovery helped bring more consistency to diagnosis and family counseling for this rare condition.
