The CDC23 gene helps control cell division by making sure key proteins are removed at the right time, so new cells form in an orderly way. This gene plays an important role in keeping chromosomes, your cells’ packages of DNA, evenly shared during division. If the CDC23 gene does not work properly, cells may divide with errors, which can upset normal growth and has been linked to some cancers. CDC23 is mainly known in research and is not a gene that has had broad public attention.
What is a gene?
Genes are sections of DNA that carry instructions your cells use to make molecules or regulate processes in the body. Some genes provide the directions for producing proteins, the working parts of cells. Others mainly help determine when certain processes happen, where they take place, and how strongly they operate. Taken together, genes affect how the body develops and works, and they can influence how you respond to food, stress, or medications. For a deeper look at this topic, you can find more in the LearnHub.
Overview
CDC23Gene function
What if the gene works
The CDC23 gene helps control cell division. It is part of a protein team that marks certain cell cycle proteins for removal, so chromosomes separate at the right time and cells divide in an orderly way.
Risk
What if the gene does not work
Milder to more severe variants in the CDC23 gene can weaken a cell cycle control complex that helps mark proteins for removal. This may disrupt orderly chromosome separation during cell division and reduce how reliably cells progress through mitosis.
Treatment
What does that mean for your treatment
No treatment or drug choice approach specific to a pathogenic or loss-of-function variant in the CDC23 gene is currently established in clinical guidelines. Care is based on the person’s symptoms and the usual treatment for the condition involved. The CDC23 gene is also being studied in cancer research as a possible marker of tumor behavior, but this has not led to routine gene-directed treatment.
Gene function
What if the gene works
Cells need careful timing to divide in an orderly way. The CDC23 gene helps run that timing by making part of a protein team that clears away certain division proteins at the right moment. Understanding how the CDC23 gene works during cell division helps explain how your body renews tissues in a controlled sequence.
The CDC23 gene makes one part of a larger protein group that manages cell division. Its protein helps this group stay organized so it can act at the right time.
This protein group marks selected division proteins so the cell can break them down when they are no longer needed. That cleanup keeps one stage of division moving forward in the proper order.
By helping remove proteins that keep copied chromosomes linked, CDC23 supports the point when those chromosomes can separate. This is a key step before one cell becomes two.
After chromosomes separate, the same control system helps the cell finish division and prepare for the next cycle. This supports normal tissue renewal and routine cell replacement.
What is a variant?
A genetic variant is a minor change in a gene’s DNA sequence. These changes are common and help shape normal human diversity, including differences in appearance, metabolism, and the way the body responds to environmental influences. Many variants have no noticeable effect and are simply part of natural genetic variation. In some cases, though, a variant can change how a gene works more substantially and may contribute to or cause a genetic condition.
Genetic variants
What if the gene does not work
Changes in the CDC23 gene can alter the protein’s shape or stability, so it may not join its cell division control group properly or may be broken down too soon. How CDC23 gene variants affect cells often comes down to weaker protein binding and less reliable timing of cell division. Milder single-letter changes may partly reduce activity, while variants that shorten the protein or disrupt how the gene is read can greatly lower or eliminate working protein.
How variants are linked to conditions
The CDC23 gene does not yet have a broadly confirmed link to a specific health condition, though this may change as research develops. Research on CDC23 gene variants and health conditions is still evolving, so anyone with a confirmed CDC23-related diagnosis should rely on guidance from their doctor or genetic counselor rather than general information.
A variant is not necessarily a diagnosis
Variants in genes are a normal feature of human biology and are common across 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 certain diagnosis, especially when multiple genes and environmental factors are involved. In some cases, though, a single well understood variant in a specific 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 CDC23 gene. Anyone concerned about what a CDC23 gene finding may mean for them or their family should speak with a doctor or genetic counselor.
Inheritance of CDC23 variants
For people reading about how variants of the CDC23 gene are inherited, there is not yet a broadly confirmed disease specific inheritance pattern tied to the CDC23 gene. As research develops, this picture may become clearer for particular health conditions. The CDC23 gene is located on chromosome 5, which is an autosome. That means a person inherits one copy of the CDC23 gene from each parent.
What does my CDC23 result mean for my family?
There is not yet a broadly confirmed inheritance pattern tied to a specific condition for CDC23, although this can become clearer as research grows. If you have a CDC23 result and want to understand what it could mean for close relatives, a doctor or genetic counselor can explain it in the context of your exact finding and family history.
Genetic information
Genetic testing
How you find out about variants
To find out whether you carry a change in the CDC23 gene, doctors use CDC23 genetic testing, usually from a blood sample or saliva. The lab reads the gene’s DNA sequence and compares it with the usual pattern to identify variants that may help explain a health condition or a family history.
When should I consider getting a genetic test?
There is not yet a broadly established CDC23-specific reason for genetic testing in routine care. Testing choices are usually based on your personal health history, family history, and a doctor or genetic counselor’s assessment.
A genetic result is only one part of your health story
A genetic result can offer meaningful insight, but the amount it reveals 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, especially those shaped by many genes, genetic information provides context rather than certainty and is most useful when considered with other parts of care. In other situations, a genetic result can give a clear answer. In areas like medication response, genetic results may help put individual experiences in context.
Pharmacogenetics
How variants shape your response to medicine
Genetic variation can affect how your body responds to medicines. Small differences in genes can change how quickly a drug is broken down, how much of it reaches its target, or how strongly your body reacts to it. This helps explain why the same treatment works well for one person but less well for another. It can also influence the chance of side effects or how sensitive someone is to a standard dose.
What is Pharmacogenetics?
Pharmacogenetics examines how genetic differences affect the way people respond to medications. It looks at links between genes and drugs to help explain why treatments can work differently from one person to another. For many medicines, genes may influence both how strongly a drug works and how the body handles it. This information can support more informed, individualized treatment decisions.

Drugs influenced by the CDC23 gene
When should I seek medical advice?
There is not currently a broadly confirmed role for this gene in how medicines are chosen or adjusted, so questions about side effects, new symptoms, or whether a treatment is right for you are best discussed with your doctor.
