The CENPP gene helps cells divide by helping build the structure that guides chromosomes into the right place during cell division. If it does not work properly, cells can mis-handle chromosomes, which can disrupt growth and development. This gene plays an important role in tissues that need steady, accurate cell turnover. Variants in the CENPP gene are uncommon and are mainly discussed in specialist genetic testing rather than everyday medicine.
What is a gene?
Genes are stretches of DNA that carry instructions your cells use to make molecules or regulate activities in the body. Some provide the directions for producing proteins, which are the parts of cells that do much of the work. Others mainly control when certain activities happen, where they happen, and how strongly they run. Together, genes affect how the body develops and works, and they can also influence how you respond to food, stress, or medications. More detailed information on this topic is available in the LearnHub.
Overview
CENPPGene function
What if the gene works
The CENPP gene helps cells organize the structures that pull chromosomes apart during cell division. This supports accurate chromosome separation as new cells form.
Risk
What if the gene does not work
Milder to more severe variants in the CENPP gene can weaken how cells build the centromere, the structure that guides chromosome separation during cell division. If CENPP works poorly, chromosomes may not attach or separate in a stable, orderly way.
Treatment
What does that mean for your treatment
At present, no CENPP-specific treatment or drug selection approach is established in clinical guidelines for people with a pathogenic or loss-of-function variant in the CENPP gene. Care is based on the person’s symptoms and clinical diagnosis rather than a gene-directed therapy.
Conditions associated with CENPP
Gene function
What if the gene works
Cell division depends on careful handling of chromosomes. The CENPP gene helps build the structure at each chromosome’s center that guides this handoff. When it is working normally, cells can line up chromosomes and separate them in a controlled, even way.
Its protein becomes part of the chromosome center, where cells organize the pulling machinery for division. This creates a stable base for the kinetochore (the structure that helps move chromosomes).
The CENPP gene works with other proteins at the chromosome center as a coordinated group. Together they assemble the parts needed for an orderly chromosome handoff during cell division.
During mitosis (cell division), this gene helps chromosomes line up before they separate. That support is part of proper chromosome separation during cell division, so each new cell receives a balanced set.
CENPP also supports the link between chromosomes and spindle fibers, the threads that pull chromosomes apart. These connections help chromosome movement stay organized as one cell becomes two.
What is a variant?
A genetic variant is a minor change in the DNA sequence of a gene. These changes are common and help account for normal human differences, such as appearance, metabolism, or the way the body responds to environmental influences. Many variants do not cause 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 CENPP gene can change how well the CENP-P protein is made, folded, or attached to its partner proteins at the centromere, which helps explain how CENPP variants affect cell division. Milder variants may partly reduce protein stability or weaken these interactions. More severe variants, including those that truncate the protein, can leave cells with little or no working CENP-P and lead to clearer problems with kinetochore assembly and chromosome separation.
How variants are linked to conditions
At this time, the CENPP gene does not yet have a broadly confirmed link to a specific health condition, so information about CENPP gene variants linked to conditions is still evolving. If you have a reported variant in the CENPP gene, your doctor or genetic counselor can interpret it in the context of your symptoms, family history, and the rest of your test results.
A variant is not necessarily a diagnosis
Genetic variants are common across the general population and are a normal feature of human biology. Most do not directly affect health and instead reflect the natural diversity seen among people. For many genes, having a variant associated with a condition points to a possible link rather than a certain diagnosis, particularly when more than one gene and environmental influences are involved. In some situations, though, one well-characterized variant in a specific gene can be 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 CENPP gene. If testing has found a change in CENPP, a doctor or genetic counselor can help put that result in context with your personal and family history.
Inheritance of CENPP variants
There is not yet a broadly confirmed disease specific pattern for the inheritance of CENPP gene variants, and research on the inheritance of CENPP gene variants is still developing. CENPP is on chromosome 16, which is an autosome. That means everyone inherits one copy of the CENPP gene from each parent.
What does my CENPP result mean for my family?
There isn't yet a broadly confirmed inheritance pattern tied to a specific condition for CENPP, though this understanding can change as research develops. If you have a specific CENPP result and questions about what it could mean for your family, a doctor or genetic counselor can explain it in the context of your personal and family history.
Genetic information
Genetic testing
How you find out about variants
To find out about CENPP variants, genetic testing reads DNA from a blood or saliva sample. A lab may look only at the CENPP gene or include it in a larger gene panel, exome, or genome test. Results show whether a variant is present and how it is classified.
When should I consider getting a genetic test?
There is not yet a widely used clinical reason to test the CENPP gene on its own. Decisions about genetic testing are usually based on your personal 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 results can be informative, but how much they explain varies with the condition and the kind of variant found. How your body functions over time is also shaped by many other factors, including lifestyle, environment, age, and medical history. For some conditions, particularly those affected by many genes, genetic information provides context rather than a definite answer and makes the most sense when considered with the rest of a person’s care. In other situations, a genetic finding can offer a clear explanation. In areas like medication response, genetic results can also help make sense of individual experiences.
Pharmacogenetics
How variants shape your response to medicine
Genetic variation can affect how your body responds to medicines. This helps explain why the same treatment works well for one person, seems weaker for another, or causes more side effects in someone else. Small inherited differences can change how the body absorbs, breaks down, or responds to a drug. These differences are common and can influence both how well a medicine works and how sensitive a person is to it.
What is Pharmacogenetics?
Pharmacogenetics is the area of study that examines how genetic differences can shape a person’s response to medications. It looks at the relationship between genes and drugs to help explain why the same treatment may work differently from one person to the next. For many medicines, genes can affect both how the body processes a drug and how strong its effects may be. This understanding can help support more informed, individualized treatment decisions.

Drugs influenced by the CENPP gene
When should I seek medical advice?
There is not yet a broadly confirmed role for this gene in guiding how medicines are used, so questions about side effects, new symptoms, or treatment response are best discussed with your doctor.
