The WDR93 gene helps your cells support motile cilia, the tiny hair-like structures that move mucus in the airways and fluid in other parts of the body. If this gene does not work properly, cilia may not beat as they should, which can affect breathing health and may also play a role in fertility or body left-right patterning. WDR93 is not a gene that has become widely known in popular culture, but it is of growing interest in genetic medicine because of its link to cilia function.
What is a gene?
Genes are stretches of DNA that hold 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. Others mainly guide when certain processes happen, where they happen, and how active they are. Taken together, genes affect how the body grows and works, and they can influence how you respond to food, stress, and medicines. More detail is available in the LearnHub.
Overview
WDR93Gene function
What if the gene works
The WDR93 gene helps motile cilia work properly. These tiny hairlike structures line the airways and some reproductive tissues, where they move mucus or fluid. This supports breathing and normal fluid movement.
Risk
What if the gene does not work
Changes in the WDR93 gene can weaken how certain cell structures are built and maintained, especially tiny hairlike cilia that help move fluid. Milder variants may partly reduce this function, while more severe variants can disrupt it more strongly.
Treatment
What does that mean for your treatment
No WDR93-specific treatment or management approach is currently established for people with a pathogenic variant in the WDR93 gene.
Gene function
What if the gene works
Some cells have tiny moving hairs that sweep fluid in the right direction. WDR93 gene function centers on helping these structures, called motile cilia, work in an organized way. When this gene is working properly, cilia can support routine tasks like clearing surfaces and moving fluid through the body.
The WDR93 gene helps cells build and maintain motile cilia, the tiny hair-like structures that beat in a set rhythm. Its protein works within the cilia structure to support steady movement.
WDR93 helps cilia move in a coordinated pattern rather than as separate strokes. This makes fluid flow across cell surfaces smoother and more controlled.
Through normal cilia motion, the WDR93 gene supports routine fluid movement in body areas that depend on these tiny hairs. This helps with steady cleaning and transport tasks at the cell surface.
What is a variant?
A genetic variant is a minor difference in the DNA sequence within a gene. These differences 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 are simply part of natural genetic variation. In some situations, though, a variant changes how a gene works more substantially and may contribute to or cause a genetic condition.
Genetic variants
What if the gene does not work
Changes in the WDR93 gene may alter amino acids within repeated parts of the protein, which can change its shape, reduce its stability, or weaken how it interacts with other proteins in the cell. More disruptive variants may shorten the protein or reduce how much is made, causing a larger loss of function, while milder variants may leave partial activity. This is how WDR93 gene variants affect protein function at a cellular level.
How variants are linked to conditions
The WDR93 gene does not yet have a broadly confirmed link to a specific health condition, though this can change as research develops. Current research on how variants in the WDR93 gene are linked to conditions has not established a single, widely accepted WDR93-related diagnosis. Anyone with a confirmed variant in the WDR93 gene should rely on guidance from their doctor or genetic counselor for interpretation in the context of their own health and family history.
A variant is not necessarily a diagnosis
Genetic variants are a usual part of human biology and are widely found in the general population. Most do not have a direct effect on health and instead reflect natural human diversity. For many genes, carrying a variant associated with a condition suggests a possible link rather than a certain diagnosis, especially when several genes and environmental influences are involved. 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 isn't yet broadly confirmed evidence on specific factors that increase or reduce health risk related to the WDR93 gene. Anyone with concerns about their personal or family risk can speak with a doctor or genetic counselor.
Inheritance of WDR93 variants
There is not yet a broadly confirmed, disease linked inheritance pattern for the WDR93 gene, so how WDR93 variants are inherited in relation to a specific condition is still being clarified. WDR93 is located on an autosome, which means you inherit one copy of the WDR93 gene from your mother and one copy from your father.
What does my WDR93 result mean for my family?
There is not yet a broadly confirmed inheritance pattern tied to a specific health condition for WDR93, although this may become clearer as research grows. If you have a WDR93 result and want to understand what it could mean for relatives, a doctor or genetic counselor can explain it in the context of your family history and the exact result.
Genetic information
Genetic testing
How you find out about variants
To find out whether you carry a change in the WDR93 gene, genetic testing for WDR93 variants looks at DNA from a blood sample, saliva, or cheek swab. A lab reads the gene's sequence and compares it with the usual pattern to identify variants. Results may show a benign variant, an uncertain finding, or a variant linked to disease.
When should I consider getting a genetic test?
There isn't yet a broadly established, WDR93-specific clinical reason for testing. Decisions about testing are best made with a doctor or genetic counselor based on your symptoms, family history, and whether a broader genetic test could help.
A genetic result is only one part of your health story
Genetic test results can offer useful insight, but what they show depends on the condition involved and the specific type of variant. Over time, how the body functions is also shaped by factors such as lifestyle, environment, age, and medical history. 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 may give a clear answer. In areas like medication response, genetic results can also help put a person’s individual experiences into context.
Pharmacogenetics
How variants shape your response to medicine
Genetic variation can affect how people respond to medicines. Small differences in DNA can change how the body breaks down a drug, moves it through the body, or responds to it at the target tissue. This helps explain why the same medication may work well for one person, do less for another, or cause more side effects in someone else. These differences are common and can influence both how effective a treatment feels and how sensitive a person is to it.
What is Pharmacogenetics?
Pharmacogenetics examines how genetic differences affect the way people respond to medications. It studies connections between genes and drugs to better understand why the same treatment can work differently from one person to another. For many medicines, genes influence either how strongly a drug works or how the body processes it. This information can help support more informed, more individualized treatment decisions. More on this topic is available in the LearnHub.
Drugs influenced by the WDR93 gene
When should I seek medical advice?
There is not yet a broadly confirmed role for this gene in guiding medication response, so questions about medicines, side effects, or changes in how you feel are best discussed with your doctor.
