The S100A13 gene contains instructions for a protein that helps your cells handle stress and release signals involved in inflammation, tissue repair, and blood vessel growth. If this gene does not work as it should, those signals may be released less effectively, which can affect how tissues respond to strain or injury. Some variants in the S100A13 gene are being studied for possible links to changes in cell growth and stress responses.
What is a gene?
A gene is a stretch of DNA that gives your cells instructions for making molecules or regulating processes in the body. Some genes hold the information needed to produce proteins, the cell components that do the work. Other genes mainly direct when certain processes occur, where they happen, and how strongly they operate. Taken together, genes affect how the body develops and works, and they can shape how you respond to food, stress, or medications.

Overview
S100A13Gene function
What if the gene works
The S100A13 gene helps cells respond to calcium signals. Its protein supports the release of certain messenger proteins, including fibroblast growth factor 1, especially during cell stress.
Risk
What if the gene does not work
Milder to more severe variants in the S100A13 gene can reduce calcium linked signaling and the stress triggered release of proteins such as FGF1. More disruptive variants may cause a larger loss of this export function.
Treatment
What does that mean for your treatment
No S100A13-specific treatment or management approach is currently established in clinical guidelines. The S100A13 gene is being studied as a possible biomarker and drug target in some cancers and blood vessel growth pathways, but this has not changed routine treatment or drug selection.
Gene function
What if the gene works
Inside your cells, the S100A13 gene helps manage calcium signals and supports the release of a small set of messenger proteins. Understanding how the S100A13 gene works helps show how cells coordinate growth, repair, and routine communication. Its role centers on signaling rather than building cell structures.
The protein made from the S100A13 gene binds calcium, a mineral that cells use as a signal. This lets it change shape and take part in passing messages inside the cell.
S100A13 helps certain messenger proteins leave the cell by a route outside the usual secretion system. This supports local signaling, including growth and repair messages such as fibroblast growth factor 1, a protein that helps nearby cells respond.
S100A13 works with other proteins to prepare selected signals for release at the cell surface. This teamwork helps cell communication stay organized when tissues need to adapt to everyday stress.
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, or the way the body reacts to environmental influences. Many variants do not cause any noticeable effects and are simply part of natural genetic variation. At times, though, a variant can change how a gene works more clearly and may contribute to or lead to a genetic condition.
Genetic variants
What if the gene does not work
Variants in the S100A13 gene can change the shape, stability, or binding behavior of the S100A13 protein, especially in regions that help it bind calcium or interact with partner proteins. In how S100A13 gene variants affect protein function, milder changes may only slightly weaken these interactions. More severe variants can markedly lower protein levels or create an unstable, shortened protein, leading to reduced activity inside cells.
How variants are linked to conditions
Current evidence on S100A13 gene variants and health conditions is still developing, and the S100A13 gene does not yet have a broadly confirmed link to a specific diagnosed condition. If you have a reported change in the S100A13 gene, your doctor or genetic counselor can interpret it in the context of your personal and family history.
A variant is not necessarily a diagnosis
Genetic variants are a usual part of being human and are widely found across the general population. Most do not directly affect health and simply contribute to normal human variation. For many genes, having 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 other situations, though, one well-understood 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 S100A13 gene. If a test result mentions S100A13, a doctor or genetic counselor can help explain what it may mean in the context of your personal and family health history.
Inheritance of S100A13 variants
There is not yet a broadly confirmed Mendelian pattern for how S100A13 gene variants are inherited in relation to a specific human condition. Current evidence does not support describing a single established mode such as autosomal dominant or autosomal recessive for S100A13 gene inheritance. The S100A13 gene is located on chromosome 1, which is an autosome, so you inherit one copy from each parent.
What does my S100A13 result mean for my family?
There is not yet a broadly confirmed inheritance pattern tied to a specific health condition for S100A13. If you have a specific S100A13 result and want to understand what it could mean for your relatives, 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
S100A13 genetic testing usually looks for DNA changes in a blood or saliva sample. A lab reads the S100A13 gene and checks whether a variant is present, then reports whether the finding is known to be linked with health effects, uncertain, or likely benign. Results can confirm that a variant was found, but they cannot predict every symptom or outcome.
When should I consider getting a genetic test?
There is not yet a broadly established reason to get genetic testing specifically for the S100A13 gene. Testing is usually considered based on your personal health history, family history, and the bigger clinical picture, together with a doctor or genetic counselor.
A genetic result is only one part of your health story
A genetic test result can provide meaningful insight, but how much it reveals depends on the condition and the specific type of variant. Over time, many other factors also influence how the body works, including lifestyle, environment, age, and medical history. In some conditions, especially those shaped by many genes, genetic information offers context rather than certainty and is best considered 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 place a person’s individual experiences in context.
Pharmacogenetics
How variants shape your response to medicine
Genetic variation can affect how your body responds to certain medicines. Small differences in genes can change how a drug is absorbed, broken down, moved through the body, or how strongly it acts where it is needed. This helps explain why the same medication may work well for one person, cause more side effects in another, or have less effect in someone else. These differences are common and are one reason treatment response can vary from person to person.
What is Pharmacogenetics?
Pharmacogenetics examines how differences in genes affect the way a person responds to medications. It studies the relationships between genes and drugs to help explain why the same treatment may work differently from one person to another. For many medicines, genes influence both how strongly a drug works and how the body handles it. This information can support treatment decisions that are better informed and more individualized.

Drugs influenced by the S100A13 gene
When should I seek medical advice?
There is not yet a broadly confirmed role for this gene in guiding medication choice, so any concerns about symptoms, treatment, or side effects are best discussed with your doctor or pharmacist.
History
The S100A13 gene was identified as part of the broader effort to map the S100 family of human genes in the late 20th century. In recent decades, awareness of this gene’s role has grown as researchers compared related S100 genes across different tissues and chromosomes. Early work placed the S100A13 gene within a cluster of S100 genes on chromosome 1, which helped organize how this gene family was studied. From these first observations, research expanded steadily as sequencing methods improved and made gene catalogs more complete. Its history is mainly tied to the wider story of modern gene discovery, especially the period when many human genes were being named, mapped, and matched to protein families.
