The CENPE gene helps cells line up and separate chromosomes correctly when they divide. In medicine, this gene is important because it helps regulate one of the last checks before a cell splits into two. If the gene does not work well, cells may divide with the wrong amount of genetic material or stop dividing, which can affect growth and early brain development. Rare disease-causing variants have been linked to inherited conditions that can include short stature, small head size, and developmental delay.
What is a gene?
Genes are sections of DNA that carry instructions your cells use to make molecules or manage processes in the body. Some genes hold the directions for making proteins, which are the parts of cells that do much of the work. Other genes mainly help regulate when certain processes happen, where they take place, and how strongly they occur. Together, genes affect how the body develops and works, and they can influence how you respond to food, stress, or medicines.

Overview
CENPEGene function
What if the gene works
The CENPE gene helps move chromosomes into place as cells divide. This supports accurate sharing of genetic material between new cells.
Risk
What if the gene does not work
Variants in the CENPE gene can weaken this cell division protein to different degrees, from milder to more severe changes. When the CENPE gene does not work properly, chromosomes may not line up and separate normally as cells divide.
Treatment
What does that mean for your treatment
No CENPE-specific treatment or management approach is currently established for people with a pathogenic or loss-of-function variant in the CENPE gene. The CENPE gene is being studied as a possible cancer drug target, but this has not led to a standard treatment for inherited CENPE-related conditions.
Conditions associated with CENPE
Gene function
What if the gene works
During cell division, your cells need every chromosome to line up and move in a controlled way. The CENPE gene helps chromosomes line up during cell division by providing a motor protein that works on the cell’s internal tracks. This careful movement supports accurate sharing of genetic material into new cells.
The CENPE gene helps guide chromosomes toward the middle of the cell during cell division. This positioning gives each new cell the best chance to receive a complete set of chromosomes.
Its protein works at the attachment point on each chromosome and interacts with microtubules (tiny fibers that act like tracks). This link helps chromosomes stay connected to the spindle, the structure that pulls them into place.
CENPE also supports the cell’s timing checks before chromosomes separate. By helping cells confirm that chromosomes are properly lined up, it supports a smooth, orderly step into the next phase of division.
What is a variant?
A genetic variant is a slight change in the DNA sequence within a gene. These changes are common and are part of normal human diversity, including differences in appearance, metabolism, and how the body responds to environmental influences. Many variants do not cause any noticeable effect and simply represent natural genetic variation. Sometimes, 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 CENPE gene can change the shape, stability, or movement of its protein, which may weaken chromosome alignment and separation during cell division. Milder variants may leave some activity intact, while more severe variants can sharply reduce protein function or stop the protein from being made at all. This range helps explain how CENPE gene variants affect cell division at the cellular level.
How variants are linked to conditions
Research on how variants of the CENPE gene are linked to conditions is still developing. At present, the CENPE gene does not yet have a broadly confirmed link to one specific health condition, and anyone with a confirmed CENPE-related diagnosis should follow advice from their doctor or genetic counselor rather than general information.
A variant is not necessarily a diagnosis
Genetic variants are common in the general population and are a normal part of human biology. Most do not have a direct effect on health and simply contribute to 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 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 risks related to the CENPE gene. If a change in CENPE has been found in you or your family, a doctor or genetic counselor can help explain what it may mean for your personal risk.
Inheritance of CENPE variants
The CENPE gene inheritance pattern linked to the best described CENPE-related condition is autosomal recessive. This means a child usually inherits one CENPE variant from each parent, while parents who carry a single variant are typically unaffected carriers. When both parents carry a variant in the CENPE gene, each pregnancy has a 25% chance of an affected child, a 50% chance of a carrier child, and a 25% chance of a child without the familial variants. Because the CENPE gene is on chromosome 4, this pattern affects children of any sex similarly.
What does my CENPE result mean for my family?
There is not yet a broadly confirmed inheritance pattern tied to a specific condition for the CENPE gene, though this can become clearer as research grows. If you have a specific CENPE result and questions about what it could mean for your family, a doctor or genetic counselor can help explain it in the context of your own health and family history.
Genetic information
Genetic testing
How you find out about variants
CENPE variants are usually found through genetic testing for CENPE variants using a blood or saliva sample. Labs read the DNA in the CENPE gene, often as part of an exome, genome, or multigene panel, and compare it with a reference sequence to look for changes. Results may show a pathogenic variant, a benign variant, or a variant of uncertain significance.
When should I consider getting a genetic test?
There is not yet a broadly established CENPE-specific reason for testing. Decisions about genetic testing are usually based on the overall pattern of symptoms or family history and are best made with a doctor or genetic counselor.
A genetic result is only one part of your health story
Genetic results can provide useful insight, but how much they explain varies by the condition and the specific type of variant involved. Over time, many other factors also influence how the body functions, including lifestyle, environment, age, and medical history. In some conditions, especially those shaped by many genes, genetic information provides context rather than certainty and is best considered alongside 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 perspective.
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 bloodstream, or responds to it at its target. This helps explain why the same treatment may work well for one person, have less effect in another, or cause more side effects in someone who is more sensitive to it.
What is Pharmacogenetics?
Pharmacogenetics examines how differences in genes can affect a person’s response to medications. It studies the relationship 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 help support more informed, individualized treatment decisions.

Drugs influenced by the CENPE gene
When should I seek medical advice?
There is not yet a broadly confirmed role for this gene in predicting how medicines will work, so medication side effects, treatment response, or other health concerns are best discussed with your doctor.
