The STARD13 gene helps keep cell growth, shape, and movement under control, acting like part of your cells’ internal braking system. If it does not work properly, cells may move or divide in a less controlled way, which can play a role in cancer development. This gene plays an important role in the signals that tell cells when to spread, attach, or stop moving. Most people who hear about the STARD13 gene do so in cancer research, where it is studied for how it may influence tumor behavior.
What is a gene?
Genes are stretches of DNA that carry instructions your cells use to make molecules or regulate processes in the body. Some genes provide the directions for making proteins, the parts of cells that do the work. Other genes mainly control when certain processes happen, where they take place, and how active they are. Together, genes influence how the body develops and functions, and they can shape how you respond to food, stress, or medications. To go deeper into this topic, you can find more in the LearnHub.
Overview
STARD13Gene function
What if the gene works
The STARD13 gene helps cells control shape, movement, and growth. Its protein acts like a brake on signals that drive cell motion, helping tissues stay organized.
Risk
What if the gene does not work
Milder to more severe variants in the STARD13 gene can reduce how well its protein restrains signals that organize a cell’s internal scaffold. When that control is weakened, cells may have less orderly shape, movement, and attachment.
Treatment
What does that mean for your treatment
For a pathogenic or loss-of-function variant in the STARD13 gene, no STARD13-specific treatment or management approach is currently established. The STARD13 gene is being studied in cancer research as a possible biomarker and pathway marker, but this has not changed routine drug choices.
Gene function
What if the gene works
Your cells use the STARD13 gene to keep internal movement signals under control. Its protein acts like a brake on pathways that shape the cell’s inner scaffold, helping cells attach, spread, and move in an orderly way. Understanding STARD13 gene function helps explain how tissues keep their structure during everyday cell activity.
The STARD13 gene helps switch off Rho signals, which are cell messages that guide shape and movement. This keeps those messages timed and balanced instead of staying active for too long.
Its protein helps organize actin, the support fibers that give cells their shape and help them push or pull. This lets cells adjust their outline and internal tension in a coordinated way.
STARD13 activity supports focal adhesions, which are the contact points that help cells grip their surroundings. This helps cells stay attached, spread out, and move with better control as tissues renew themselves.
What is a variant?
A genetic variant is a minor change in the DNA sequence within a gene. These changes are common and help shape normal differences between people, such as appearance, metabolism, and the way the body reacts to environmental influences. Many 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 substantially and may contribute to or cause a genetic condition.
Genetic variants
What if the gene does not work
Variants in the STARD13 gene can change the protein’s shape, shorten it, or make it less stable, which may weaken its control over cell signaling tied to cell shape and movement. In practical terms, how STARD13 gene variants affect protein activity depends on the DNA change: some are milder and partly reduce function, while more severe variants can leave little or no working protein. This can lead to greater disruption of cellular signaling and organization.
How variants are linked to conditions
The STARD13 gene does not yet have a broadly confirmed link to a specific health condition, though research on STARD13 gene variants and health conditions is still developing. If you have a confirmed variant in the STARD13 gene, your doctor or genetic counselor can explain what it may mean in the context of your personal and family history.
A variant is not necessarily a diagnosis
Gene variants are common and are a normal part of human biology. Most do not have a direct effect on health and are simply part of natural human diversity. For many genes, having a variant associated with a condition suggests a possible link rather than a definite diagnosis, especially when several genes and environmental factors also contribute. In some situations, though, a single well-characterized variant in a specific 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 STARD13 gene. Anyone with questions about personal or family risk can discuss them with a doctor or genetic counselor.
Inheritance of STARD13 variants
There is not yet a broadly confirmed, disease-associated inheritance pattern for the STARD13 gene, so how variants of the STARD13 gene are inherited in relation to a specific genetic condition is still being worked out. The STARD13 gene is located on chromosome 13, which is an autosome, so you inherit one copy from your mother and one copy from your father. As research develops, the picture may become clearer for any health conditions linked to this gene.
What does my STARD13 result mean for my family?
There is not yet a broadly confirmed inherited pattern tied to a specific health condition for STARD13. If you have a STARD13 result and want to know what it could mean for close relatives, a doctor or genetic counselor can explain it in the context of your exact finding and family history.
Genetic information
Genetic testing
How you find out about variants
To find out whether you carry a change in the STARD13 gene, STARD13 genetic testing analyzes DNA from a blood sample, saliva, or a cheek swab. Labs usually read the gene as part of a multigene panel, exome sequencing, or genome sequencing and compare the result with reference DNA to identify variants.
When should I consider getting a genetic test?
There isn't yet a broadly established reason to get genetic testing just for the STARD13 gene. Testing decisions are usually based on your own health history, family history, and whether a doctor or genetic counselor thinks a broader test could be helpful.
A genetic result is only one part of your health story
Genetic test results can offer useful insight, but how much they reveal depends on the condition and the specific type of variant involved. Over time, many factors, including lifestyle, environment, age, and medical history, influence how the body works. In some conditions, especially those shaped by many genes, genetic information provides 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 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 absorbs, breaks down, transports, or responds to a drug, so the same treatment may work better for one person than for another. This is a common part of normal human variation and can influence both how well a medicine helps and how likely someone is to have side effects.
What is Pharmacogenetics?
Pharmacogenetics focuses on how genetic differences affect the way people respond 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 either how strongly a drug works or how the body handles it. This information can support more informed and more individualized treatment decisions.

Drugs influenced by the STARD13 gene
When should I seek medical advice?
There is not yet a broadly confirmed role for this gene in guiding medication choices, so any concerns about side effects, medicine safety, or how well a treatment is working are best discussed with your doctor.
