The WDR38 gene helps cells build and control tiny moving structures called cilia, including the tail that lets sperm swim. The protein made by this gene helps your cells keep these structures shaped and moving as they should. If the gene does not work properly, sperm tails may be short, bent, or absent, or they may move poorly, which can lead to male infertility.
What is a gene?
Genes are pieces of DNA that carry instructions your cells use to make molecules or regulate processes in the body. Some genes provide the information needed to produce proteins, which are the working parts of cells. Others mainly control when certain processes happen, where they take place, and how strongly they operate. Together, genes affect how the body develops and functions, and they can also influence how you respond to food, stress, or medications.

Overview
WDR38Gene function
What if the gene works
The WDR38 gene helps build and support the tiny moving structures called cilia and flagella. These small parts help some cells move fluid and, in sperm cells, support tail movement.
Risk
What if the gene does not work
Changes in the WDR38 gene can weaken how its protein supports cilia and flagella, the tiny cell structures that help cells move. Milder to more severe variants may leave some function intact or more clearly disrupt this movement system.
Treatment
What does that mean for your treatment
No treatment or drug choice is currently guided specifically by pathogenic variants in the WDR38 gene. The WDR38 gene is being studied in sperm tail and motile cilia biology, but this work has not yet produced therapies used in clinical guidelines.
Gene function
What if the gene works
Some cells rely on tiny moving hairs called cilia to keep fluids flowing or to help sperm move. The WDR38 gene function centers on supporting these motion systems by helping cells organize proteins inside motile cilia and sperm tails. This steady role helps these structures move in a controlled, repeatable way.
The WDR38 gene helps cells organize parts of motile cilia and sperm tails, which are built for movement. This supports the routine motion these structures need to do their jobs.
Inside these moving structures, the WDR38 gene helps proteins work together in an ordered way. That coordination helps cilia move fluid along body surfaces and helps sperm tails push cells forward.
What is a variant?
A genetic variant is a minor change in a gene’s DNA sequence. These changes are common and are part of normal human diversity, including differences in appearance, metabolism, or the way the body responds to environmental influences. Many do not have any noticeable effect and simply represent natural genetic variation. At times, though, a variant can change how a gene works more significantly and may contribute to or cause a genetic condition.
Genetic variants
What if the gene does not work
Variants in the WDR38 gene can change the shape, stability, or amount of the WDR38 protein, reducing how well it joins protein groups that build cilia and flagella. Milder changes may leave some activity, while more severe variants can shorten the protein or stop it from being made. This spectrum of WDR38 gene variant effects can cause less or more disruption of sperm tail structure and, in WDR38 associated infertility, may influence severity.
How variants are linked to conditions
At present, variants in the WDR38 gene do not yet have a broadly confirmed link to a specific health condition, and how WDR38 gene variants are linked to conditions remains an active area of research. Anyone with a confirmed WDR38-related diagnosis should rely on guidance from their doctor or genetic counselor rather than general information.
A variant is not necessarily a diagnosis
Genetic variants are a usual part of being human and are widely found across the population. Most do not have a direct effect on health and simply reflect natural variation among people. For many genes, carrying a variant connected with a condition suggests a possible association rather than a firm diagnosis, particularly when more than one gene and environmental factors play a role. Still, there are situations in which a single well-characterized variant in a particular 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 WDR38 gene. If a change in WDR38 is found on genetic testing, its meaning usually depends on the exact variant and the person’s overall medical picture.
Inheritance of WDR38 variants
For people looking into how WDR38 gene variants are inherited, there is not yet a broadly confirmed disease-specific inheritance pattern that is established in routine human genetics. As research develops, this may become clearer for particular health conditions or traits linked to the WDR38 gene. WDR38 is located on an autosome, which means a person generally inherits one copy of the WDR38 gene from each parent.
What does my WDR38 result mean for my family?
There is not yet a broadly confirmed inheritance pattern tied to a specific health condition for WDR38, and this can change as research grows. If you have a WDR38 result and want to understand what it could mean for parents, children, brothers, sisters, or other relatives, a doctor or genetic counselor can help explain it in the context of your family history and the exact result.
Genetic information
Genetic testing
How you find out about variants
Genetic testing for WDR38 variants uses a blood, saliva, or cheek swab sample to read the WDR38 gene. A laboratory compares your DNA with a reference sequence to look for changes in the gene. Results may identify a benign variant, a variant of uncertain significance, or a variant that may help explain a health condition.
When should I consider getting a genetic test?
There is not yet a broadly established, WDR38-specific reason for genetic testing in routine care. Testing decisions are usually based on your symptoms, fertility history, and family history, together with a doctor or genetic counselor.
A genetic result is only one part of your health story
Genetic results can provide useful insight, but the amount they reveal depends on the condition and the kind of variant involved. Many factors, including lifestyle, environment, age, and medical history, influence how the body functions over time. For some conditions, particularly those shaped by many genes, genetic information offers context rather than certainty and is most helpful when considered with other parts of care. In other situations, a genetic result can give a clear answer. In areas like medication response, these results can help make sense of individual experiences.
Pharmacogenetics
How variants shape your response to medicine
Genetic variation can affect how your body handles medicines, so the same treatment may work better for one person than for another. These inherited differences can change how quickly a drug is processed, how strongly it acts in the body, or how sensitive someone is to side effects. This kind of variation is common and helps explain why medication response can differ even when people take the same medicine in the same amount.
What is Pharmacogenetics?
Pharmacogenetics looks at how genetic differences shape a person’s response to medications. By examining connections between genes and drugs, it helps clarify why the same treatment may work differently from one person to another. For many medicines, genes affect both how strongly a drug works and how the body processes it. This information can support treatment decisions that are better informed and more individualized.

Drugs influenced by the WDR38 gene
When should I seek medical advice?
There is not yet a broadly confirmed role for this gene in guiding medication choices. For questions about side effects, how well a treatment is working, or concerns about your overall health, it is best to speak with your doctor.
