The KLHL23 gene gives instructions for a protein that helps with normal protein handling inside cells, which is part of everyday cell upkeep. If it does not work as expected, that internal housekeeping may be less controlled and cells may not function as smoothly. The KLHL23 gene belongs to a larger kelch-like gene family that researchers study for its role in basic cell processes.
What is a gene?
A gene is a stretch of DNA that carries instructions your cells use to make molecules or guide processes in the body. Some genes contain the instructions for producing proteins, the working parts of cells. Others mainly help determine when and where certain processes happen, and how strongly they run. Taken together, genes affect how the body develops and functions, and they can influence how you respond to food, stress, or medications.

Overview
KLHL23Gene function
What if the gene works
The KLHL23 gene provides instructions for making a kelch-like protein. It belongs to a gene family that helps cells manage protein interactions during routine cell activity.
Risk
What if the gene does not work
Variants in the KLHL23 gene can range from milder to more severe and may change the shape or stability of its protein. This can weaken how the protein interacts with other proteins inside cells.
Treatment
What does that mean for your treatment
For a pathogenic or loss of function variant in the KLHL23 gene, no treatment or management approach that is specific to the KLHL23 gene is currently established.
Gene function
What if the gene works
Your cells constantly sort, move, and recycle proteins so everyday cell work stays on track. The KLHL23 gene helps with this kind of housekeeping by making a protein that can connect other proteins with the systems that manage them. This is part of what the KLHL23 gene does in the body every day.
The KLHL23 gene helps bring selected proteins into contact with larger cell systems that organize protein handling. This linking role supports smooth, routine cell activity.
Its protein helps direct certain proteins toward the cell’s recycling pathway, where worn out proteins can be broken down in the proteasome (the cell’s protein recycling system). This helps cells refresh proteins as part of normal upkeep.
What is a variant?
Genetic variants are small differences in the DNA sequence of a gene. They are common and help shape normal human diversity, including differences in appearance, metabolism, and how the body responds to environmental influences. Many have no noticeable effect and simply represent natural genetic variation. In some situations, 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 KLHL23 gene can alter the shape, stability, or amount of KLHL23 protein made in cells, which may weaken its ability to interact with partner proteins. Milder changes may partly reduce protein function, while more disruptive variants can lead to an unstable protein or little to no protein being produced. This is one way to understand how KLHL23 gene variants affect protein function.
How variants are linked to conditions
Current evidence on how variants in the KLHL23 gene are linked to conditions is still developing. The KLHL23 gene does not yet have a broadly confirmed link to a specific health condition, though this may change as research grows. If you have a KLHL23 variant on a test report, your doctor or genetic counselor can explain what it may or may not mean for you and your family.
A variant is not necessarily a diagnosis
Genetic variants are a routine part of human biology and are common throughout the general population. Most do not have a direct effect on health and simply reflect natural human diversity. For many genes, carrying a variant associated with a condition indicates 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 can be 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 KLHL23 gene. If KLHL23 appears on a test result and you have concerns about what it means for you or your family, a doctor or genetic counselor can help put it in context.
Inheritance of KLHL23 variants
Current evidence has not established a broadly confirmed, disease-specific Mendelian pattern for how KLHL23 gene variants are inherited, and this may become clearer as research develops. In practical terms, discussions of how KLHL23 gene variants are inherited remain limited because no single autosomal dominant, autosomal recessive, or X linked condition is firmly tied to this gene. The KLHL23 gene is located on an autosome, not a sex chromosome, so each person inherits one copy from each parent.
What does my KLHL23 result mean for my family?
There isn't yet a broadly confirmed inheritance pattern tied to a specific health condition for KLHL23. Understanding of this gene may change as research develops. If you have a specific KLHL23 result and questions about what it could mean for 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
To find variants in the KLHL23 gene, a lab analyzes DNA from a blood, saliva, or cheek swab sample. Genetic testing for KLHL23 variants works by reading the gene's sequence, comparing it with a reference sequence, and classifying any change by its likely health relevance.
When should I consider getting a genetic test?
There is not yet a broadly established, KLHL23-specific clinical reason for genetic testing. Decisions about testing are usually based on your personal health history, symptoms, and family history, and are best made with a doctor or genetic counselor.
A genetic result is only one part of your health story
A genetic result can provide valuable insight, but how much it explains depends on the condition and the kind of variant involved. Over time, many factors shape how the body works, including lifestyle, environment, age, and medical history. In some conditions, especially those influenced by many genes, genetic information provides context rather than certainty and is best understood together 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 into context.
Pharmacogenetics
How variants shape your response to medicine
Genetic variation can affect how people respond to medicines. This helps explain why the same treatment works well for one person but less well for another, or why some people are more likely to notice side effects. Part of the reason is that inherited differences can change how the body breaks down, moves, or responds to a drug. These differences are common and can influence both how well a medicine works and how sensitive someone may be to it.
What is Pharmacogenetics?
Pharmacogenetics examines how genetic differences can shape a person’s response to medicines. It studies links between genes and drugs to help explain why the same treatment may affect people in different ways. With many medications, genes influence either how strongly a drug works or how the body handles it. Understanding this can support treatment choices that are more informed and more tailored to the individual. More detail on this topic is available in the LearnHub.
Drugs influenced by the KLHL23 gene
When should I seek medical advice?
There is not yet a broadly confirmed role for this gene in guiding medication use, so questions about medicines, side effects, or changes in how you feel are best discussed with your doctor.
