The ZMYND10 gene helps build and maintain the tiny moving hairs called cilia that clear mucus from the airways and support sperm movement. When both copies carry a harmful variant, these cilia may not move well, which can lead to primary ciliary dyskinesia, with ongoing chest and sinus problems, ear infections, and sometimes fertility problems or organs developing in a reversed pattern.
What is a gene?
Genes are sections of DNA that hold instructions your cells use to make molecules or regulate activities in the body. Some genes carry the directions for producing proteins, the parts of cells that do much of the work. Others mainly help control when certain processes happen, where they take place, and how strongly they run. Together, genes affect how the body develops and works, and they can also shape how you respond to food, stress, or medications. For a deeper look at this topic, you can learn more in the LearnHub.
Overview
ZMYND10Gene function
What if the gene works
The ZMYND10 gene helps build working parts of cilia, tiny moving structures that clear mucus from airways. It also supports fluid movement in the sinuses, middle ear, and reproductive tract.
Risk
What if the gene does not work
Variants in the ZMYND10 gene can cause primary ciliary dyskinesia, often leading to chest, sinus, and ear infections. Some people also have organ laterality differences or fertility problems, and milder or more severe variants can change timing and severity.
Treatment
What does that mean for your treatment
No treatment or drug choice specific to the ZMYND10 gene is currently established in clinical guidelines. Research on the ZMYND10 gene is helping scientists understand cilia-related disease and may support future targeted therapies.
Conditions associated with ZMYND10
Gene function
What if the gene works
Tiny moving hairs called cilia help clear mucus, move fluid, and support normal function in several parts of the body. In cells that rely on these structures, the ZMYND10 gene helps build the motor machinery that makes cilia beat smoothly. This background helps explain what the ZMYND10 gene does in normal cilia movement.
The ZMYND10 gene helps cells build the tiny motors needed for normal cilia movement. These motors give cilia the force to beat in a smooth, repeated pattern.
The protein made from the ZMYND10 gene works with cell helpers that fold and steady new motor parts. This step helps each part reach the right shape before use.
Before a cilium starts moving, many motor pieces must be put together inside the cell. The ZMYND10 gene helps this assembly process so the finished motors can be placed into the cilium and work together properly.
What is a variant?
A genetic variant is a small difference in the DNA sequence of a gene. These differences are common and help create normal human diversity, such as variation 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 situations, though, a variant can change how a gene functions more substantially and may contribute to or cause a genetic condition.
Genetic variants
What if the gene does not work
Variants in the ZMYND10 gene can make the protein unstable or leave cells with too little of it, which disrupts the assembly of dynein arms, the motor parts that help cilia move. This is how ZMYND10 gene variants affect cilia function. More disruptive variants often leave little or no working protein, while milder variants may preserve some activity. That difference can influence how much cilia movement is reduced and, in primary ciliary dyskinesia, how early and strongly features appear.
How variants are linked to conditions
Pathogenic variants in the ZMYND10 gene cause primary ciliary dyskinesia, an inherited condition often linked with chronic wet cough, repeated sinus or chest infections, and sometimes fertility problems or organ placement differences present from birth. This well-established ZMYND10 gene variant link to primary ciliary dyskinesia usually appears when both copies of the gene carry a disease-causing variant.
A variant is not necessarily a diagnosis
Genetic variants are a usual part of being human and are common across the general population. Most have no direct impact on health and simply reflect natural human variation. For many genes, carrying a variant connected with a condition suggests a possible association rather than a definite diagnosis, especially when several genes and environmental factors 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?
For ZMYND10, risk is mainly shaped by inheritance rather than lifestyle. A child’s chance is higher when both parents carry a harmful ZMYND10 change, especially in families with an affected relative or where the parents are related by blood, such as cousins.
Inheritance of ZMYND10 variants
Variants in the ZMYND10 gene are inherited in an autosomal recessive pattern. This means a child usually inherits one nonworking copy from each parent, and both parents are typically healthy carriers. When both parents carry a ZMYND10 gene variant, each pregnancy has a 25% chance of the child inheriting both variants, a 50% chance of being a carrier, and a 25% chance of inheriting neither variant. In practical terms, ZMYND10 gene inheritance affects sons and daughters equally because the gene is on a nonsex chromosome.
What does my ZMYND10 result mean for my family?
Changes in the ZMYND10 gene are linked to a family pattern where close relatives may also carry the same gene change, even if they do not have symptoms. Brothers and sisters may have the same condition or be carriers, and parents are often carriers. Other relatives may also carry the change, so family testing may be worth discussing if this result is tied to a confirmed diagnosis.
Genetic information
Genetic testing
How you find out about variants
Variants in the ZMYND10 gene are usually found through genetic testing for ZMYND10 variants, using a blood sample, saliva, or cheek swab. A lab reads the gene’s DNA code and checks for changes, often as part of a panel, exome, or genome test. Results may identify a variant linked to disease, a benign variant, or an uncertain finding.
When should I consider getting a genetic test?
Genetic testing for the ZMYND10 gene may be worth considering if someone has signs of primary ciliary dyskinesia, a condition that can cause a long-lasting wet cough, repeated sinus or ear infections, and sometimes trouble having children. It can also help when this condition runs in the family.
A genetic result is only one part of your health story
A genetic result can be informative, but how much it reveals depends on the condition and the type of variant involved. Many factors, including lifestyle, environment, age, and medical history, shape how the body functions over time. 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 context.
Pharmacogenetics
How variants shape your response to medicine
Genetic variation can affect how people respond to medicines. Some people break down a drug faster or slower than expected, while others may be more or less sensitive to its effects. This is a common reason the same treatment can work well for one person but not as well for another, or cause different side effects.
What is Pharmacogenetics?
Pharmacogenetics focuses on how genetic differences shape medication response. It studies relationships between genes and drugs to help explain why the same treatment affects people in different ways. For many medicines, genes influence how strongly a drug works or how the body handles it. This understanding can support more informed, individualized treatment decisions.

Drugs influenced by the ZMYND10 gene
When should I seek medical advice?
There is not yet a broadly confirmed role for this gene in guiding how medicines are chosen or how people respond to them, so concerns about side effects, new symptoms, or changes in treatment are best discussed with your doctor.
