Your cells depend on the CDC14A gene to help control key cell signals, especially in the inner ear and during sperm development. The protein made by this gene supports the tiny hair cells that turn sound into nerve signals and also helps sperm form and move normally. If both copies of the gene do not work properly, a person can have inherited hearing loss. Some affected males may also have infertility because their sperm do not move as they should.
What is a gene?
Genes are stretches of DNA that hold information cells use to make molecules or regulate processes in the body. Some genes carry the information needed to make proteins, the parts of cells that do the work. Other genes mostly help control when certain processes happen, where they occur, and how strongly they operate. Together, genes affect how the body develops and works, and they can influence how you respond to food, stress, or medications. For a more in depth look at this topic, you can learn more in the LearnHub.
Overview
CDC14AGene function
What if the gene works
The CDC14A gene helps remove phosphate tags from certain proteins. This supports normal hearing by helping inner ear cells work properly and also supports sperm development and movement.
Risk
What if the gene does not work
Variants in the CDC14A gene most often cause inherited hearing loss. Some, especially more disruptive variants, are also linked to male infertility, while milder or differently placed variants may affect hearing alone.
Treatment
What does that mean for your treatment
No treatment or drug choice approach tied specifically to pathogenic variants in the CDC14A gene is currently established in clinical guidelines. Researchers are studying the CDC14A gene to better understand inherited hearing loss and related fertility effects, but this has not yet led to a gene directed therapy.
Conditions associated with CDC14A
Gene function
What if the gene works
Many of your cells rely on the CDC14A gene for steady timing and structure. It helps make a protein that removes phosphate tags, small chemical signals that change how other proteins behave. In everyday cell life, the CDC14A gene helps control cell division and cilia function.
CDC14A makes a phosphatase, an enzyme that removes phosphate tags from selected proteins. This acts like an off or reset signal and helps cells adjust protein activity at the right time.
This gene helps coordinate key steps of cell division, especially around the cell's organizing centers and the final split into two cells. That timing supports orderly growth and routine tissue renewal.
CDC14A also helps cells build and maintain cilia, the tiny hairlike structures that sense signals or move fluid across cell surfaces. This supports normal cell structure and communication in many parts of the body.
What is a variant?
A genetic variant is a slight difference in the DNA sequence within a gene. These differences are common and help shape normal human diversity, such as variation in appearance, metabolism, or the way the body responds to environmental factors. Many have no obvious effect and are simply part of natural genetic variation. Sometimes, though, a variant changes how a gene works more substantially and can contribute to or cause a genetic condition.
Genetic variants
What if the gene does not work
Some variants in the CDC14A gene slightly reduce the amount or activity of the protein, while more disruptive variants can shorten it or stop it from being made, causing a larger loss of function. Variants in the CDC14A gene linked to hearing loss usually disturb cell signaling and the upkeep of inner ear hair cells. Greater loss of function may be associated with earlier or more marked hearing loss, and in some males infertility.
How variants are linked to conditions
Pathogenic variants in both copies of the CDC14A gene cause autosomal recessive sensorineural hearing loss, often starting at birth or in early childhood. In some males, CDC14A gene hearing loss and infertility occur together, with hearing loss plus reduced fertility due to sperm changes. This means CDC14A-related conditions can range from isolated hearing loss to a combined hearing loss and male infertility picture.
A variant is not necessarily a diagnosis
Genetic variants are a normal feature of human biology and are common in 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 suggests a possible link rather than a definite diagnosis, especially when multiple genes and environmental factors also play a role. In some situations, though, 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 CDC14A gene. For many living with a CDC14A gene change, risk is mainly shaped by the exact variant inherited and family pattern rather than clear lifestyle factors, and a doctor or genetic counselor can help explain personal risk.
Inheritance of CDC14A variants
CDC14A-related conditions are usually inherited in an autosomal recessive pattern. In practical terms, how variants of the CDC14A gene are inherited usually means a person receives one nonworking copy from each parent, while parents with one copy are typically carriers. When both parents carry a CDC14A variant, each pregnancy has a 25% chance of a child inheriting both altered copies, a 50% chance of being a carrier, and a 25% chance of inheriting neither altered copy. Mothers and fathers pass these variants on equally.
What does my CDC14A result mean for my family?
For family members, a CDC14A result usually matters most for brothers, sisters, and future children because this gene is most often linked to a recessive hearing-related condition. Close relatives may also carry the same gene change even if they do not have symptoms. If both parents are carriers, each child can inherit the condition, so the result may be relevant for siblings and for family planning.
Genetic information
Genetic testing
How you find out about variants
Genetic testing for CDC14A variants usually uses a blood or saliva sample and DNA sequencing, often as part of a hearing loss gene panel. It shows whether you carry a variant in the CDC14A gene and may also check for missing or extra pieces of the gene.
When should I consider getting a genetic test?
Genetic testing may be worth considering if there is unexplained hearing loss that starts early in life or runs in the family. Changes in the CDC14A gene are a known cause of some inherited hearing loss, and in some families they can also be linked with reduced male fertility.
A genetic result is only one part of your health story
A genetic result can provide useful insight, but how much it reveals varies based on the condition and the specific type of variant. Many other factors, including lifestyle, environment, age, and medical history, also 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 useful when viewed alongside other parts of care. In other situations, a genetic result can offer a clear answer. In areas such as medication response, genetic results can help make sense of individual experiences.
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 more slowly, while others may be more or less sensitive to its effects. This is common and can influence how well a treatment works or how likely side effects are.
What is Pharmacogenetics?
Pharmacogenetics is the area of study that examines how genetic differences affect the way people respond to medications. It explores the relationship between genes and drugs to help explain why the same treatment can work differently from one person to another. For many medicines, genes influence both how strongly a drug works and how the body processes it. This understanding can support more informed and more individualized treatment decisions.

Drugs influenced by the CDC14A gene
When should I seek medical advice?
There is no broadly confirmed role for this gene in guiding medication choice or dose right now, so concerns about medicines, side effects, or new health changes are best discussed with your doctor.
