The CDC27 gene helps control the cell cycle, the timed steps cells use to grow and divide. The protein made by this gene helps your cells remove certain proteins at the right moment, so chromosomes separate in an orderly way during cell division. If the CDC27 gene does not work properly, cells may divide out of step or keep growing when they should pause. Variants in the CDC27 gene have been linked mainly to problems in cell growth control and may play a role in some cancers.
What is a gene?
Genes are stretches of DNA that give cells the instructions they use to make molecules or manage activities in the body. Some provide the code for proteins, which do much of the cell’s work. Others are used mainly to regulate when certain activities happen, where they happen, and how strongly they are carried out. Taken together, genes affect how your body develops and works, and they can also influence how you respond to food, stress, and medications. More detailed information on this topic is available in the LearnHub.
Overview
CDC27Gene function
What if the gene works
The CDC27 gene helps control how cells divide by helping switch off certain proteins at the right time. This supports orderly cell cycle progression and normal tissue growth.
Risk
What if the gene does not work
Changes in the CDC27 gene can mildly or more strongly disrupt how cells label and clear proteins during cell division. This may disturb cell cycle timing and the orderly separation of chromosomes.
Treatment
What does that mean for your treatment
No CDC27-specific treatment or management approach is currently established for pathogenic variants in the CDC27 gene. In research, CDC27 is being studied mainly as a cancer biomarker and possible drug target because changes in its activity may influence how some cancers grow and respond to treatment.
Gene function
What if the gene works
Your cells need precise timing to grow, copy themselves, and divide in an orderly way. The CDC27 gene helps manage that timing by supporting a protein team that clears away cell cycle proteins after they finish their job. This keeps routine cell turnover moving in a controlled, step by step way.
One of the main jobs of the CDC27 gene is to help tag selected proteins for breakdown when they are no longer needed. This cleanup step lets the cell switch from one stage of activity to the next.
This gene helps control the timing of mitosis (the process of one cell dividing into two cells). It supports orderly chromosome separation and helps the cell complete division in the right sequence.
CDC27 helps the APC/C (a protein team that drives key steps in cell division) stay organized and connect with helper proteins. This is a central part of what the CDC27 gene does in cells.
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, such as differences 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, however, 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 CDC27 gene can change the shape or stability of the CDC27 protein, so it may not join its partner proteins properly or may be broken down too soon. In studies of how CDC27 gene variants affect protein function, milder changes may only weaken how it binds to other proteins, while more severe variants can greatly reduce the amount of working protein in the cell. This can disrupt the timed removal of proteins that control cell division.
How variants are linked to conditions
The CDC27 gene does not yet have a broadly confirmed link to a specific health condition, although research on CDC27 gene variants and health conditions is still developing. If you have a confirmed variant in the CDC27 gene on a test report, your doctor or genetic counselor can explain what that specific finding may mean for you or your family.
A variant is not necessarily a diagnosis
Genetic variants are a usual feature of human biology and are widely found across the population. Most do not directly affect health and instead reflect normal variation among people. For many genes, having a variant associated with a condition points to a possible link, not a certain diagnosis, particularly when several genes and environmental influences also play a part. In some situations, though, one well understood variant in a particular gene is enough to confirm the 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 CDC27 gene. If genetic testing has found a change in CDC27, a doctor or genetic counselor can help explain what that result may mean for you and your family.
Inheritance of CDC27 variants
There is not yet a broadly confirmed, disease specific inheritance pattern for the CDC27 gene, so how CDC27 gene variants are inherited in relation to a defined health condition is still being clarified. The CDC27 gene is located on chromosome 17, which is an autosome, so you inherit one copy from your mother and one copy from your father. This means any CDC27 gene change can be passed down through either side of the family.
What does my CDC27 result mean for my family?
There is not yet a broadly confirmed inheritance pattern tied to a specific, well-established health condition for CDC27, and this picture may become clearer as research grows. If you have a specific CDC27 result and want to understand what it could mean for relatives, a doctor or genetic counselor can explain it in the context of your own test finding and family history.
Genetic information
Genetic testing
How you find out about variants
Genetic testing for CDC27 variants usually uses a blood sample or saliva sample to read the DNA in the CDC27 gene. It can show whether you carry a variant in this gene, often as part of a multigene panel or broader sequencing test. Results are reviewed with your medical history because some findings are clearly meaningful and others are uncertain.
When should I consider getting a genetic test?
There is not yet a broadly established, CDC27-specific reason for genetic testing in routine care. Decisions about testing are usually based on your own health history, family history, and whether a doctor or genetic counselor thinks a broader test would be helpful.
A genetic result is only one part of your health story
Genetic findings can provide useful insight, but how much they reveal depends on the condition and the type of variant involved. Many 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 offers context rather than certainty and is best understood together with other aspects of care. In other situations, a genetic result can give a clear answer. In areas such as medication response, it can also help place personal experiences in context.
Pharmacogenetics
How variants shape your response to medicine
Genetic variation can affect how people respond to medicines. Small differences in a person’s DNA can change how the body breaks down a drug, moves it through the body, or responds to it at its target. This helps explain why the same medication may work well for one person, seem less effective for another, or cause more side effects in someone else. These differences are common and are one part of why treatment response can vary from person to person.
What is Pharmacogenetics?
Pharmacogenetics examines how genetic differences can affect the way people respond to medications. It focuses on patterns between genes and drugs to help explain why the same treatment may work differently from one person to another. For many medicines, genes can influence both how strongly a drug works and how the body processes it. This information can support treatment decisions that are more informed and more individualized.

Drugs influenced by the CDC27 gene
When should I seek medical advice?
There is not yet a broadly confirmed role for this gene in guiding medication choice or dose. If you have concerns about side effects, new symptoms after starting a medicine, or how treatments may affect your health, discuss them with your doctor or pharmacist.
History
In the 1970s, researchers studying baker’s yeast identified a group of “cell division cycle” genes that helped map the basic timing of cell growth and division. From these first observations, research expanded steadily. CDC27 was named as part of that early CDC family, and later work showed that closely related versions exist in humans and many other species. This broader link mattered because it connected simple lab models with human biology in a clear, practical way. As medical science evolved, so did understanding of this gene. CDC27 is mainly known in science through its role in the larger story of cell cycle research rather than through a single public event or celebrity-linked discovery.
