The S100A14 gene helps control how certain cells grow, mature, and stick to nearby cells, especially in tissues that line organs and body surfaces. If it does not work as expected, cell growth and movement may become less controlled, which can play a role in the development or spread of some cancers. In medicine, this gene is important because it helps regulate signals linked to normal cell behavior. Changes in the S100A14 gene are mainly studied as part of cancer biology rather than as a common inherited condition.
What is a gene?
Genes are stretches of DNA that carry instructions cells use to make molecules or manage activities throughout the body. Some genes provide the directions for producing proteins, which do much of the cell’s work. Others are mainly involved in regulating 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 influence how you respond to food, stress, and medications. More detail on this topic is available in the LearnHub.
Overview
S100A14Gene function
What if the gene works
The S100A14 gene helps make a protein that responds to calcium signals, especially in lining tissues. It supports cell growth, development, movement, and routine communication between cells.
Risk
What if the gene does not work
DNA changes in the S100A14 gene can range from milder to more severe and may reduce how well cells handle calcium related signals and communication. This can alter growth control, cell movement, and stress responses.
Treatment
What does that mean for your treatment
No S100A14-specific treatment or management approach is currently established for pathogenic or loss-of-function variants in the S100A14 gene. In research, the S100A14 gene is being studied mainly as a cancer biomarker and possible drug target, but this has not yet changed routine treatment decisions.
Gene function
What if the gene works
In surface tissues such as the skin, mouth, and digestive tract, the S100A14 gene helps cells respond to calcium signals during everyday renewal. Its protein supports steady growth, normal maturation, and contact between neighboring cells. Understanding how the S100A14 gene works helps explain how these tissues keep an organized structure.
The S100A14 gene makes a protein that binds calcium, a mineral cells use as a signal. This lets cells adjust their activity when calcium levels shift.
Its protein helps pass signals that guide when lining cells grow and when they pause. This supports an orderly pattern of tissue renewal.
This gene supports the steps that help surface cells mature into their usual roles. This helps tissues keep the right balance of newer and more specialized cells.
Its protein also influences how cells keep their shape and stay connected to nearby cells. This supports stable tissue layers in places like the skin, mouth, and digestive tract.
What is a variant?
A genetic variant is a small difference in the DNA sequence within a gene. These differences are common and are part of 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. In some cases, though, a variant can change a gene’s function more significantly and may contribute to or cause a genetic condition.
Genetic variants
What if the gene does not work
Variants in the S100A14 gene can affect protein stability and binding, changing how much protein is made and how well it interacts with calcium and other cell proteins. Milder variants may cause only small shifts in activity, while more severe variants can greatly reduce activity or stop the protein from being made at all. These S100A14 gene variants affect protein function to different degrees, which can alter cell signaling and protein interactions.
How variants are linked to conditions
Current evidence on how variants in the S100A14 gene are linked to conditions is still developing. The S100A14 gene does not yet have a broadly confirmed link to a specific health condition, so anyone with a confirmed S100A14-related finding should rely on guidance from their doctor or genetic counselor for interpretation.
A variant is not necessarily a diagnosis
Genetic variants are a routine part of human biology and are widely seen in the general population. Most do not have a direct impact on health and simply reflect natural variation among people. For many genes, carrying a variant associated with a condition suggests a possible link rather than a definite diagnosis, especially when several genes and environmental factors also play a part. In some situations, though, a single 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 S100A14 gene. Changes in this gene have mostly been studied as possible links to cancer risk in some groups, but they are not used on their own to predict what will happen for one person. Anyone concerned about personal or family risk should speak with a doctor or genetic counselor.
Inheritance of S100A14 variants
There is not yet a broadly confirmed Mendelian pattern for how S100A14 gene variants are inherited in relation to a specific human genetic condition, and this picture may become clearer as research develops. For families asking how S100A14 gene variants are inherited, current evidence does not support a single well-established pattern such as autosomal dominant or autosomal recessive. The S100A14 gene is located on chromosome 1, which is an autosome, so each person inherits one copy from each parent.
What does my S100A14 result mean for my family?
There is not yet a broadly confirmed inheritance pattern tied to a specific health condition for S100A14, so a result in this gene does not have a clear, standard meaning for family members. If you have a specific S100A14 result and want to understand what it could mean in your family, a doctor or genetic counselor can help explain it in the context of your personal and family history.
Genetic information
Genetic testing
How you find out about variants
If you are having testing for variants in the S100A14 gene, a lab studies DNA from a blood or saliva sample to look for changes, often using panel testing or broader sequencing. Results may identify a known variant, show no reportable change, or find a variant of uncertain significance, which means its health effect is not yet clear.
When should I consider getting a genetic test?
There is not yet a broadly established, S100A14-specific reason for genetic testing in routine care. Testing decisions are usually based on your personal health and family history, often with a doctor or genetic counselor guiding whether broader testing makes sense.
A genetic result is only one part of your health story
A genetic result can provide useful insight, yet how much it explains varies depending on the condition and the type of variant involved. Many factors, including lifestyle, environment, age, and medical history, influence how the body functions over time. For some conditions, especially those shaped 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 such as 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 genes can change how the body breaks down a drug, moves it through the body, or responds to it at its target. That helps explain why the same medication may work well for one person, work less well for 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 examines how differences in genes can affect the way a person responds to medicines. By studying links between genes and medications, it helps explain why the same treatment may work differently in different people. For many drugs, genes can influence how powerfully a medicine works or how the body handles it. This information can support more informed, personalized treatment choices.

Drugs influenced by the S100A14 gene
When should I seek medical advice?
There is not yet a broadly confirmed role for this gene in guiding medication response, so questions about your health, treatment plan, or medicine side effects are best discussed with your doctor.
