The CENPF gene gives cells instructions for a protein that helps chromosomes (packages of DNA) line up and separate during cell division. This gene plays an important role in growth before birth and in organs that rely on steady cell turnover. If it does not work properly, cells may divide abnormally, which can affect the eyes, brain, intestines, and overall development. Pathogenic variants in both copies of the CENPF gene can cause Strømme syndrome, a rare inherited condition.
What is a gene?
Genes are stretches of DNA that give your cells instructions for making molecules or guiding processes in the body. Some genes provide the directions for building proteins, the parts of cells that do much of the work. Others mainly regulate when certain processes happen, where they take place, and how strongly they occur. Together, genes affect how the body develops and functions, and they can also influence how you respond to food, stress, or medications.

Overview
CENPFGene function
What if the gene works
The CENPF gene helps cells divide in an organized way. Its protein supports chromosome movement and timing during cell division, which helps tissues grow and renew normally.
Risk
What if the gene does not work
More severe variants in the CENPF gene can cause Strømme syndrome, often with small head size, eye changes, and intestinal atresia. Milder variants may lead to a broader range of features, including developmental delay, with symptoms appearing earlier or later.
Treatment
What does that mean for your treatment
No CENPF-specific treatment or drug choice approach is currently established. Care is based on a person’s symptoms and clinical needs rather than the CENPF result itself. The CENPF gene is also being studied in cancer research as a possible biomarker and treatment target, but this has not led to guideline-based therapy.
Conditions associated with CENPF
Gene function
What if the gene works
CENPF helps your body make new cells in a controlled, orderly way during growth and routine tissue renewal. In daily cell function, the CENPF gene works during cell division to guide how chromosomes are handled. This makes CENPF gene function in cell division important for normal cell turnover across many tissues.
CENPF becomes active as cells get ready to divide and stays involved through mitosis (the process of one cell splitting into two). This helps the steps of division happen in an organized sequence.
The CENPF gene helps link chromosomes to spindle fibers, the tiny structures that pull chromosomes during division. This connection helps chromosomes line up and respond to the forces moving them.
By supporting chromosome movement and positioning, CENPF helps each new cell receive a full set of chromosomes. That steady handoff is a key part of healthy cell renewal.
What is a variant?
A genetic variant is a small alteration in the DNA sequence of a gene. These changes are common and help create normal human diversity, including 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 cases, 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
Changes in the CENPF gene can weaken chromosome movement and related structural tasks during cell division. Some variants shorten the protein or stop it being made, while others change its shape, stability, or binding to partner proteins. This shows how CENPF variants affect protein function: milder variants may leave some activity, but more severe variants can remove it almost completely. In people with two severe variants, symptoms often begin earlier and involve more body systems.
How variants are linked to conditions
The best established condition linked to variants in the CENPF gene is Strømme syndrome, a rare inherited condition. People with this diagnosis often have eye changes, a smaller than expected head size, and part of the intestine that is narrowed or blocked. Some also have developmental delay or differences affecting the heart, kidneys, or hearing. Finding harmful variants in both copies of the CENPF gene can confirm the diagnosis.
A variant is not necessarily a diagnosis
Genetic changes are a usual part of human biology and are common across the general population. Most variants 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 definite diagnosis, especially when several genes and environmental factors also play a part. In some situations, though, a single well-characterized variant in a particular 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 CENPF gene. In families with a known CENPF-related condition, risk is mainly shaped by the inherited gene change itself rather than lifestyle or everyday exposures.
Inheritance of CENPF variants
CENPF-related conditions that are clearly established in human genetics are inherited in an autosomal recessive pattern. In practical terms, this means a person usually inherits one altered copy of the CENPF gene from each parent. When both parents carry one variant, each pregnancy has a 25% chance of resulting in a child with the condition, a 50% chance of resulting in a child who is a carrier, and a 25% chance of resulting in a child with two usual copies. This is the main answer to how CENPF gene variants are inherited.
What does my CENPF result mean for my family?
For families affected by a harmful CENPF change, the main pattern is recessive. This usually means parents can be healthy carriers, while brothers and sisters may also be carriers or, less often, have the same condition. Close relatives may want to learn whether the change runs in the family, especially if there is a history of similar pregnancy or childhood health problems.
Genetic information
Genetic testing
How you find out about variants
To look for changes in the CENPF gene, CENPF gene testing for inherited conditions uses DNA from a blood or saliva sample. A lab reads the gene’s sequence, often as part of a multigene panel or exome test, and compares it with the usual sequence to identify variants.
When should I consider getting a genetic test?
Consider genetic testing for the CENPF gene if a baby or child has a pattern of findings such as a small head size, eye development problems, developmental delay, or a bowel blockage at birth. Testing may also help when this rare condition is suspected from family history or prenatal scans.
A genetic result is only one part of your health story
A genetic result can provide useful insight, but what it tells you varies based on the condition and the type of variant involved. Over time, many factors, including lifestyle, environment, age, and medical history, also shape how the body works. For some conditions, especially those influenced 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 can give a clear answer. In areas such as 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. This helps explain why the same treatment works well for one person, has less effect in another, or causes more side effects in someone else. Small differences in how the body breaks down, moves, or responds to a drug are common, and they can influence both benefit and sensitivity.
What is Pharmacogenetics?
Pharmacogenetics examines how genetic differences shape the way people respond to medications. By studying connections between genes and drugs, it helps explain why the same treatment may work differently from one person to another. For many medicines, genes can affect both how strongly a drug works and how the body processes it. This information can support treatment decisions that are better informed and more individualized.

Drugs influenced by the CENPF gene
When should I seek medical advice?
There is not yet a broadly confirmed role for this gene in predicting how medicines will work or what side effects they may cause. If you have concerns about a medication, side effects, or a health problem linked to this gene, it is best to talk with your doctor.
