The ST13 gene helps your cells fold and steady other proteins, especially during times of stress. This gene plays an important role in keeping cell signals working smoothly, including signals linked to hormone receptors. If the ST13 gene does not work well, some proteins may not take the right shape or may break down more easily, which can disrupt normal cell function. Changes in ST13 are mostly studied in research, including cancer biology, rather than as a widely known inherited condition.
What is a gene?
Genes are stretches of DNA that give your cells instructions for making molecules or managing activities in the body. Some genes carry the information needed to make proteins, the parts of cells that do much of the work. Others mainly regulate when certain processes happen, where they take place, and how active they are. In combination, genes affect how the body grows and works, and they can influence how you respond to food, stress, and medications.

Overview
ST13Gene function
What if the gene works
The ST13 gene helps cells fold proteins into the right shape by working with helper proteins called heat shock proteins. This supports everyday cell function and helps cells cope with stress.
Risk
What if the gene does not work
Changes in the ST13 gene can reduce how well cells fold and stabilize other proteins. Milder variants may partly weaken this protein quality control system, while more severe variants can disrupt it more substantially.
Treatment
What does that mean for your treatment
No ST13-specific treatment or management approach is currently established in clinical guidelines. The ST13 gene is being studied as a possible biomarker in some cancers, but this has not yet guided routine drug choices.
Gene function
What if the gene works
Inside your cells, the ST13 gene supports the routine care of proteins. It works with protein folding helpers to guide other proteins into shapes they can use. Understanding how the ST13 gene helps proteins fold makes it easier to see how cells stay organized and work smoothly each day.
The ST13 gene works with HSP70 helper proteins (proteins that assist folding) as new proteins take shape. This support helps proteins settle into a stable form that the cell can use.
Its protein helps these folding helpers hold onto a protein during a key step in the process. This gives the cell time to guide folding in a more controlled way.
ST13 supports the cell’s wider protein care network across many tissues. By improving how folding helpers do their work, it helps many proteins stay stable and ready for routine tasks.
What is a variant?
A genetic variant is a minor difference in the DNA sequence of a gene. These differences are common and help shape normal human diversity, such as variation 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. Sometimes, though, a variant can change how a gene functions to a greater extent and may contribute to or cause a genetic condition.
Genetic variants
What if the gene does not work
Variants in the ST13 gene can change the shape, stability, or amount of the ST13 protein, especially in parts needed to bind heat shock proteins that help manage protein folding inside cells. Some ST13 gene variants have a milder effect and only weaken these interactions, while more severe variants can greatly reduce protein stability or stop the protein from being made. This range helps explain how ST13 gene variants affect protein folding support at the cellular level.
How variants are linked to conditions
The ST13 gene does not yet have a broadly confirmed link to a specific health condition, although research on ST13 gene variants and health conditions is still developing. If you carry a reported variant in the ST13 gene, its meaning is best understood alongside your symptoms, medical history, and family history.
A variant is not necessarily a diagnosis
Genetic variants are a routine part of human biology and are widely found in the general population. Most do not have a direct effect on health and instead reflect natural human diversity. For many genes, carrying a variant associated with a condition suggests a possible link rather than a definite diagnosis, particularly when several genes and environmental influences 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 clearly increase or reduce health risk related to the ST13 gene. If a change in ST13 is found on genetic testing, a doctor or genetic counselor can help explain what it may mean in the context of your personal and family history.
Inheritance of ST13 variants
There is not yet a broadly confirmed disease specific ST13 gene inheritance pattern in human genetics, so ST13 gene inheritance is not currently described as autosomal dominant, autosomal recessive, or X linked for a well established ST13 related condition. The ST13 gene is located on chromosome 22, which is an autosome. That means everyone inherits two copies of this gene overall, one from each parent.
What does my ST13 result mean for my family?
There isn't yet a broadly confirmed inheritance pattern tied to a specific condition for ST13, though this understanding can change as research develops. If you have a specific ST13 result and questions about what it could mean for your family, a doctor or genetic counselor can explain it in the context of your personal and family history.
Genetic information
Genetic testing
How you find out about variants
To find out whether you carry a variant in the ST13 gene, labs can do ST13 genetic testing using blood, saliva, or a cheek swab. The test reads the DNA sequence and compares it with the usual version to look for changes, then reports whether a variant was found.
When should I consider getting a genetic test?
There is not yet a broadly established, ST13-specific reason for genetic testing in routine care. Testing decisions are usually based on your symptoms, personal health history, and family history, together with a doctor or genetic counselor.
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 the kind of variant involved. How the body works 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 individual 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 breaks down a drug, moves it through the body, or responds to it at its target. This helps explain why the same medication 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 why treatment response can vary from person to person.
What is Pharmacogenetics?
Pharmacogenetics looks at how differences in a person’s genes can affect their response to medications. It examines links between genes and drugs to help explain why the same treatment may work differently from one person to another. For many medicines, genes influence how strongly a drug works or how the body processes it. This information can help guide more informed and individualized treatment decisions. More detail on this topic is available in the LearnHub.
Drugs influenced by the ST13 gene
When should I seek medical advice?
There is not yet a broadly confirmed role for this gene in guiding medication choices. If you have side effects, your medicine is not working as expected, or you have concerns about treatment, talk with your doctor or pharmacist before making changes.
