The CCDC149 gene helps make a protein involved in building and supporting the tail of sperm cells, which is needed for normal sperm movement. If this gene does not work properly, sperm may move poorly or have an unusual shape, which can contribute to male infertility. Research on the CCDC149 gene is mainly focused on reproductive health, and it has not become a widely known gene in popular culture.
What is a gene?
A gene is a stretch of DNA that carries instructions your cells use to make molecules or direct processes in the body. Some genes hold the instructions for making proteins, the parts of cells that do the work. Other genes mostly help regulate when certain processes happen, where they happen, and how active they are. Together, genes affect how the body develops and works, and they can also influence how you respond to food, stress, or medications. For a deeper look at this topic, you can learn more in the LearnHub.
Overview
CCDC149Gene function
What if the gene works
The CCDC149 gene helps cells make a protein involved in cilia and flagella, the tiny moving structures on some cells. In sperm, this supports normal tail structure and movement.
Risk
What if the gene does not work
Variants in the CCDC149 gene can reduce or disrupt the CCDC149 protein and its normal interactions inside cells. Milder variants may leave some activity, while more severe variants can lead to much less or no function.
Treatment
What does that mean for your treatment
For pathogenic or loss-of-function variants in the CCDC149 gene, no treatment or drug choice approach based on this gene is currently established.
Gene function
What if the gene works
Inside cells, the CCDC149 gene supports orderly cell architecture. Its protein has a shape that helps it connect with other proteins, which is important for normal cell organization. Understanding how the CCDC149 gene supports cell structure helps show how cells keep key parts aligned and stable.
The protein made from the CCDC149 gene helps other cell proteins attach and line up in an organized way. This supports stable cell structure during normal daily cell activity.
Inside your cells, the CCDC149 gene contributes to keeping structural parts positioned correctly. That steady arrangement helps cells maintain their usual shape and function.
What is a variant?
A genetic variant is a slight difference in the DNA sequence within a gene. These differences are common and are part of normal human variation, including differences in appearance, metabolism, and the way the body responds to environmental influences. Many variants do not have any noticeable effect and simply represent natural genetic diversity. In some cases, though, a variant changes 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 CCDC149 gene can alter the protein's shape, stability, or ability to connect with other proteins, especially when a DNA change affects key binding regions or creates a shortened protein. Milder variants may leave some protein activity intact, while more severe variants can greatly reduce the amount of protein made or make it unstable. This is how variants influence the CCDC149 gene's function at a molecular level.
How variants are linked to conditions
CCDC149 does not yet have a broadly confirmed link to a specific health condition, though research on how CCDC149 gene variants are linked to health conditions is still developing. If you carry a variant in the CCDC149 gene, your own test result and guidance from a doctor or genetic counselor are the best way to understand what it may mean for you.
A variant is not necessarily a diagnosis
Variants in genes are common across the general population and are a normal feature of human biology. Most do not directly affect health and instead reflect natural differences between people. For many genes, having a variant associated with a condition points to a possible link rather than a certain diagnosis, particularly when several genes and environmental influences are part of the picture. There are cases, though, where one specific, well-characterized variant in a 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 CCDC149 gene. If a change in CCDC149 has been found in your family or on testing, a doctor or genetic counselor can help explain what it may mean for your personal risk.
Inheritance of CCDC149 variants
There is not yet a broadly confirmed, disease-specific inheritance pattern for the CCDC149 gene, so the inheritance of CCDC149 gene variants is still being clarified as research develops. Each person carries two copies of the CCDC149 gene in their usual set of chromosomes, with one copy inherited from each parent. That means a child can receive a CCDC149 variant from either side of the family.
What does my CCDC149 result mean for my family?
There is not yet a broadly confirmed inheritance pattern tied to a specific condition for CCDC149, though this can change as research develops. If you have a CCDC149 result and want to understand what it could mean for your relatives, a doctor or genetic counselor can help interpret it in the context of your family history.
Genetic information
Genetic testing
How you find out about variants
To find out whether you carry a variant in the CCDC149 gene, a lab can analyze DNA from a blood sample, saliva, or a cheek swab. CCDC149 genetic testing reads the gene's code and compares it with the usual sequence to look for changes. Results may identify a variant, or show no variant was found.
When should I consider getting a genetic test?
There is not yet a broadly established, CCDC149-specific reason to get genetic testing in routine care. Decisions about testing are best made with a doctor or genetic counselor based on your symptoms and family history.
A genetic result is only one part of your health story
A genetic result can provide useful insight, but how much it reveals depends on the condition and the kind of variant involved. How the body works over time is also shaped by many other factors, including lifestyle, environment, age, and medical history. For 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 offer 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. Two people can take the same treatment, yet one may get better benefit while the other may be more sensitive to side effects. This happens in part because inherited differences can change how the body breaks down, moves, or responds to a drug. These differences are common and are one reason medication response is not the same for everyone.
What is Pharmacogenetics?
Pharmacogenetics examines how genetic differences shape a person’s response to medications. It focuses on the relationship between genes and drugs to better understand why the same treatment may work differently from one person to another. For many medications, genes influence how the body processes a drug and how strong its effects are. This information can support more informed, individualized treatment decisions.

Drugs influenced by the CCDC149 gene
When should I seek medical advice?
There isn't yet a broadly confirmed role for this gene in guiding medicine choices, so it's best to speak with your doctor or pharmacist about any new symptoms, side effects, or concerns about how a treatment is working.
