The KRT35 gene provides instructions for a hair keratin, one of the structural proteins that helps build the hair shaft as it grows. The protein made by this gene helps your cells give hair its strength, shape, and resilience. If the KRT35 gene does not work properly, hair may grow with a different texture or less strength, although many variants in this gene have little clear effect on health. The KRT35 gene is mainly known in hair biology rather than through public awareness or celebrity stories.
What is a gene?
A gene is a stretch of DNA that carries instructions your cells use to make molecules or regulate processes in the body. Some genes hold the directions for making proteins, the parts of cells that do the work. Other genes mainly guide when certain processes happen, where they happen, and how strongly they are carried out. Together, genes help shape how the body develops and functions, and they can influence how you respond to food, stress, or medications. For a deeper look at this topic, you can read more in LearnHub.
Overview
KRT35Gene function
What if the gene works
The KRT35 gene helps make a hair keratin protein found in the hair shaft. Working with other keratins, it supports hair structure, strength, and flexibility.
Risk
What if the gene does not work
Changes in the KRT35 gene can weaken how its protein joins the keratin network in hair-forming cells. Milder variants may partly reduce filament stability, while more severe variants can disrupt assembly more substantially.
Treatment
What does that mean for your treatment
No KRT35-specific treatment or management approach is currently established.
Gene function
What if the gene works
KRT35 supports hair as each strand takes shape. It is one of the keratin genes that supplies the tough protein framework inside the hair shaft. When this gene works normally, hair forming cells can organize these proteins into strong, flexible fibers. That normal activity underlies the KRT35 gene's role in hair structure.
KRT35 helps build the tough inner framework of the hair shaft. It joins with matching hair keratins to form long support fibers inside developing hair cells.
Its protein pairs with type II hair keratins, a matching group of hair proteins. These pairs assemble into intermediate filaments (tiny support cables) that help each strand keep its form.
As hair forming cells mature, KRT35 becomes part of the hardened material in the hair shaft. This gives strands a mix of strength and flexibility for everyday washing, brushing, and styling.
What is a variant?
A genetic variant is a minor change in a gene’s DNA sequence. These changes are common and help explain normal differences among people, such as appearance, metabolism, or the way the body responds to environmental influences. Many variants do not have any noticeable effect and are simply part of natural genetic variation. In some cases, though, a variant changes how a gene works more substantially and can contribute to or directly cause a genetic condition.
Genetic variants
What if the gene does not work
Variants in the KRT35 gene can change the keratin 35 protein so it folds less well, is less stable, or does not link normally with other hair keratins. In plain terms, how KRT35 gene variants affect hair keratin structure often comes down to whether the protein can still assemble into strong filaments inside hair-forming cells. Milder variants may allow partial function, while more severe variants can greatly disrupt filament assembly or lead to little or no working protein.
How variants are linked to conditions
KRT35 does not yet have a broadly confirmed link to a specific health condition, and research on KRT35 gene variants linked to conditions is still developing. If you have a reported variant in the KRT35 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
Genetic variants are a usual feature of human biology and are widely found across the population. Most do not directly affect health and instead reflect normal human diversity. For many genes, having a variant associated with a condition points to a possible link, not a certain diagnosis, particularly when several genes and environmental influences play a role. In some situations, though, one well characterized variant in a particular gene is enough to confirm the 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 KRT35 gene. If a change in KRT35 shows up on genetic testing, its meaning often depends on the exact variant and the rest of your health and family history.
Inheritance of KRT35 variants
There is not yet a broadly confirmed disease inheritance pattern for the KRT35 gene, so how KRT35 gene variants are inherited in relation to a specific health condition is still being clarified. Current evidence has not established a single well accepted autosomal dominant, autosomal recessive, or X linked pattern for KRT35 related disease. The KRT35 gene is located on chromosome 17, which is an autosome, so you inherit one copy from your mother and one copy from your father.
What does my KRT35 result mean for my family?
There is not yet a broadly confirmed family pattern tied to KRT35 for a specific well-established health condition, and this picture may change as research grows. If you have a KRT35 result and want to know what it could mean for relatives, a doctor or genetic counselor can help interpret it in the context of your family history and the exact result.
Genetic information
Genetic testing
How you find out about variants
To find KRT35 variants, KRT35 genetic testing for variants usually checks DNA from blood, saliva, or a cheek swab. A lab reads the KRT35 gene sequence and compares it with the usual pattern to identify variants. Results may show no variant, a benign variant, or a variant that needs clinical interpretation.
When should I consider getting a genetic test?
There is not yet a broadly established clinical reason to test the KRT35 gene on its own. Genetic testing decisions are usually based on your symptoms and family history, with a doctor or genetic counselor helping decide whether a broader test would be more useful.
A genetic result is only one part of your health story
A genetic finding can provide useful insight, but how much it reveals varies depending on the condition and the type of variant involved. Many factors, including lifestyle, environment, age, and medical history, shape how the body works over time. For some conditions, especially those influenced by many genes, genetic information provides context rather than certainty and is most helpful when considered alongside other parts of care. In other situations, a genetic result can offer a clear answer. In areas such as medication response, genetic results may also help place personal experiences in 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. This helps explain why the same treatment works well for one person, has little effect for another, or causes more side effects in someone else. These differences are common and are one part of the bigger picture, along with age, other health conditions, and other medicines.
What is Pharmacogenetics?
Pharmacogenetics examines how genetic differences affect a person’s response to medications. It looks at gene drug patterns 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 understanding can support treatment decisions that are better informed and more individualized.

Drugs influenced by the KRT35 gene
When should I seek medical advice?
There is no broadly confirmed role for this gene in how people respond to medicines, so questions about side effects, drug safety, or whether a treatment is working are best discussed with your doctor. Seek medical advice if you develop new symptoms after starting a medicine or if your usual treatment does not seem to be helping.
