The TMPRSS13 gene gives cells instructions for a protein on the cell surface that cuts other proteins, helping the skin and the lining of the airways develop and work properly. If it does not work as expected, these protective tissues may not mature or repair as well, and the effects can vary with the specific variant. Researchers also study the TMPRSS13 gene because it may influence how some viruses enter cells.
What is a gene?
Genes are stretches of DNA that carry instructions your cells use to make molecules or regulate activities in the body. Some genes provide the directions for producing proteins, which do much of the work inside cells. Other genes mainly control when certain processes happen, where they take place, and how strongly they run. Together, genes affect how the body develops and works, and they can influence how you respond to food, stress, or medications. For a closer look at this topic, you can find more in the LearnHub.
Overview
TMPRSS13Gene function
What if the gene works
The TMPRSS13 gene gives cells instructions for a protein on the cell surface that cuts and activates other proteins. This may help support normal cell signaling and tissue function in areas like the skin and airways.
Risk
What if the gene does not work
Variants in the TMPRSS13 gene can range from milder changes to more severe ones, partly reducing or largely removing TMPRSS13 protein activity. This can alter how certain proteins are cut and switched on at the cell surface.
Treatment
What does that mean for your treatment
No TMPRSS13-specific treatment or management approach is currently established for people with a pathogenic or loss-of-function variant in the TMPRSS13 gene. The TMPRSS13 gene is being studied as a possible drug target and biomarker in some cancers and in research on how certain respiratory viruses enter cells.
Gene function
What if the gene works
Many cells that line body surfaces rely on the TMPRSS13 gene to fine tune proteins at their outer edge. It helps make a membrane bound protease, which is a protein cutting enzyme attached to the cell surface. Understanding TMPRSS13 gene function helps explain how cells adjust signals and protein activity in a controlled way.
The TMPRSS13 gene helps cells cut selected proteins at the cell surface. This controlled trimming can switch proteins on or change how they behave.
Because its protein sits in the cell membrane, it helps cells respond to nearby signals in their surroundings. This supports orderly communication between cells and the tissues around them.
This role is especially relevant in cells that form body linings and protective surfaces. By processing proteins in these areas, it helps routine tissue function stay coordinated.
What is a variant?
A genetic variant is a minor change in the DNA sequence of a gene. These changes are common and help create normal human diversity, including differences 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 situations, however, a variant can change how a gene functions more significantly and may contribute to or cause a genetic condition.
Genetic variants
What if the gene does not work
Variants in the TMPRSS13 gene can change the shape of the TMPRSS13 protein, how well it reaches the cell surface, or how much protein-cutting activity it keeps. In how TMPRSS13 gene variants affect protein function, milder changes may partly reduce stability or activation, while more severe variants can greatly lower or fully stop activity. These changes mainly affect cellular processing and protein interactions rather than pointing to one specific health outcome.
How variants are linked to conditions
The TMPRSS13 gene does not yet have a broadly confirmed link to a specific health condition, although research on how variants in the TMPRSS13 gene are linked to conditions is still developing. If a test finds a change in the TMPRSS13 gene, the result is best interpreted with your doctor or genetic counselor alongside your personal and family history.
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 effect on health and simply contribute to natural human diversity. 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 are involved. In some situations, however, 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 TMPRSS13 gene. Risk, if a change is found, can depend on the exact gene variant and family history rather than on any clearly proven lifestyle factor. Anyone concerned about personal risk can talk with a doctor or genetic counselor.
Inheritance of TMPRSS13 variants
For families trying to understand how TMPRSS13 gene variants are inherited, there is not yet a broadly confirmed Mendelian inheritance pattern tied to a specific TMPRSS13 related condition. Research on this gene is still developing, so its clinical inheritance picture may become clearer over time. The TMPRSS13 gene is located on chromosome 11, which is an autosome. That means each person inherits one copy of the TMPRSS13 gene from each parent.
What does my TMPRSS13 result mean for my family?
There is not yet a broadly confirmed inherited pattern tied to a specific medical condition for TMPRSS13. Research on this gene is still developing, so a TMPRSS13 result does not currently give a clear, standard answer about which relatives might also be affected or carry the same change. If you have a specific TMPRSS13 finding, family implications are usually interpreted in the context of your own result and health history.
Genetic information
Genetic testing
How you find out about variants
To find out whether you carry a TMPRSS13 variant, TMPRSS13 genetic testing analyzes DNA from a blood, saliva, or cheek swab sample. A lab reads the TMPRSS13 gene and compares it with a reference sequence to look for changes. Results may show a variant or no meaningful change.
When should I consider getting a genetic test?
There is not yet a broadly established TMPRSS13-specific reason to get genetic testing in routine care. Testing decisions are usually based on your personal health and family history, ideally with a doctor or genetic counselor.
A genetic result is only one part of your health story
A genetic finding can provide useful insight, but how much it explains varies by 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 influenced by many genes, genetic information offers context rather than certainty and is best considered along with 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 in context.
Pharmacogenetics
How variants shape your response to medicine
Genetic variation can affect how people respond to medicines. Some people break down or transport a drug differently, so the same treatment can work better in one person, have less effect in another, or cause more side effects. These inherited differences are common and are one reason medication response can vary from person to person.
What is Pharmacogenetics?
Pharmacogenetics examines how differences in genes affect the way people respond to medications. It studies links between genes and drugs to help explain why the same treatment can work differently from one person to another. For many medicines, genes influence either how powerfully a drug works or how the body handles it. This information can support treatment choices that are more informed and more individualized. More detail on this topic is available in the LearnHub.
Drugs influenced by the TMPRSS13 gene
When should I seek medical advice?
There is not yet a broadly confirmed role for this gene in guiding medication choice or response. If you have concerns about side effects, how well a treatment is working, or possible interactions between medicines, supplements, and health conditions, it is best to discuss them with your doctor.
History
TMPRSS13 entered the scientific literature in the early 2000s, when researchers were mapping a growing family of related human genes. It was first described under the name MSPL before TMPRSS13 became the standard gene symbol. Initially understood only through visible traits, later recognized as tied to a specific gene, this period reflected a broader shift in genetics from naming proteins first to defining the genes behind them. From these first observations, research expanded steadily as scientists compared TMPRSS13 with other similar genes found in human tissues. Its history is mainly part of the larger story of how modern gene discovery moved from basic cataloging to more precise classification. Over time, descriptions became more precise as naming systems and gene databases were standardized.
