The KRT24 gene gives your body instructions for making keratin 24, a structural protein that helps certain surface lining cells stay strong, especially in the skin and the clear front surface of the eye. This gene helps your body maintain the supportive fibers that let these cells cope with rubbing and everyday wear. If the KRT24 gene does not work properly, these cells may be less stable and their protective barrier may not function as well. KRT24 is mainly studied for its role in keeping epithelial tissues healthy.
What is a gene?
A gene is a piece of DNA that carries instructions your cells use to make molecules or guide processes in the body. Some genes provide the directions for making proteins, which are the parts of cells that do much of the work. Others mainly help regulate when certain processes happen, where they take place, and how active they are. Together, genes affect how the body grows and works, and they can influence how you respond to food, stress, or medications. To look into this subject more closely, you can find more in the LearnHub.
Overview
KRT24Gene function
What if the gene works
The KRT24 gene helps make keratin 24, a structural protein in certain surface lining cells. It supports the internal scaffolding that helps these cells keep their shape and handle everyday wear.
Risk
What if the gene does not work
Changes in the KRT24 gene can range from milder to more severe variants. They may reduce or alter keratin 24, a structural protein that helps certain surface cells, especially in the eye, stay stable and resilient.
Treatment
What does that mean for your treatment
No KRT24 specific treatment, management approach, or drug choice strategy is currently established for pathogenic or loss of function variants in the KRT24 gene.
Gene function
What if the gene works
KRT24 helps make one of the keratin proteins used in certain surface lining cells. These proteins act like flexible internal cables, helping cells stay organized during everyday movement and renewal. Understanding what the KRT24 gene does helps explain how these cells keep their shape over time.
The KRT24 gene helps make a keratin protein that becomes part of a cell’s inner support system. This flexible framework helps certain surface lining cells keep their shape and stay organized.
KRT24 protein joins with partner keratins to form strong fibers inside cells. These fibers help cells tolerate rubbing, stretching, and other routine physical stress.
In renewing surface tissues, KRT24 supports the steady structure of maturing cells. This helps layers of cells remain aligned as older cells are replaced.
What is a variant?
A genetic variant is a small alteration in the DNA sequence of a gene. These changes are common and are part of normal human diversity, such as differences in appearance, metabolism, or how 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 more substantially change how a gene functions and may contribute to or cause a genetic condition.
Genetic variants
What if the gene does not work
How KRT24 gene variants affect protein function depends on the type of DNA change. Milder variants may slightly alter the keratin 24 protein’s shape or stability, which can weaken its pairing with partner keratins and make cell filaments less sturdy. More severe variants, including changes that disrupt splicing or shorten the protein, can greatly reduce the amount of usable keratin 24 or stop it from joining the filament network at all.
How variants are linked to conditions
KRT24 does not yet have a broadly confirmed link to a specific health condition, although research on KRT24 gene variants and health conditions is still developing. Findings may change as larger human studies become available. If you have a confirmed variant in the KRT24 gene, your doctor or genetic counselor can explain what that result may mean in the context of your personal and family history.
A variant is not necessarily a diagnosis
Genetic variants are a common and expected part of human biology across the general population. Most do not have a direct effect on health and simply reflect normal human diversity. For many genes, carrying a variant associated with a condition indicates a possible link rather than a definite diagnosis, especially when multiple genes and environmental factors also play a role. 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 isn't yet broadly confirmed evidence on specific factors that increase or reduce health risk related to the KRT24 gene. If a change in KRT24 is found on genetic testing, a doctor or genetic counselor can help explain what it may mean for your personal and family risk.
Inheritance of KRT24 variants
There is not yet a broadly confirmed, disease-associated inheritance pattern for the KRT24 gene, so KRT24 gene inheritance is not currently described in the same clear way as for genes tied to a well-defined inherited condition. As research develops, this picture may become more specific. The KRT24 gene is located on chromosome 17, which is an autosome, so each person typically inherits one copy from each parent.
What does my KRT24 result mean for my family?
There isn’t yet a broadly confirmed inherited pattern linking KRT24 to a specific recognized health condition in families. If you have a KRT24 result, what it means for relatives depends on the exact finding and why the test was done, and a genetics specialist can help explain that in the context of your family.
Genetic information
Genetic testing
How you find out about variants
KRT24 genetic testing looks for variants in a DNA sample, usually saliva or blood. Labs read the KRT24 gene as part of a gene panel, exome, or genome test and compare it with a reference sequence. Results may show a variant, no relevant variant, or a finding whose meaning is still being clarified.
When should I consider getting a genetic test?
There is not yet a broadly established, KRT24-specific reason for genetic testing in routine care. Decisions about testing are usually based on your symptoms, family history, and guidance from a doctor or genetic counselor.
A genetic result is only one part of your health story
Genetic results can be informative, but how much they reveal varies based on the condition and the type of variant involved. Over time, many factors, including lifestyle, environment, age, and medical history, also shape how the body works. For some conditions, especially those influenced 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 put individual experiences into perspective.
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, moves, or responds to a drug. This helps explain why the same treatment works well for one person, works less well for another, or causes more side effects in someone else.
What is Pharmacogenetics?
Pharmacogenetics examines how genetic differences can shape a person’s response to medicines. By looking at connections between genes and drugs, it helps explain why the same treatment may work differently from one person to another. For many medications, genes affect both how strongly a drug works and how the body handles it. This information can support more personalized and better informed treatment decisions.

Drugs influenced by the KRT24 gene
When should I seek medical advice?
There is no broadly confirmed role for this gene in guiding medication choice or dose right now, so questions about side effects, new symptoms, or how a treatment is working are best discussed with your doctor.
