The CENPS gene helps cells repair DNA damage and keep chromosomes organized when cells divide. When it does not work properly, cells may struggle to grow normally and can build up DNA errors over time. This gene plays an important role in healthy development, especially in tissues that need steady cell renewal. Rare pathogenic variants in the CENPS gene have been linked to Fanconi anemia, a condition that can affect growth, blood cell production, and the body’s ability to respond to DNA damage.
What is a gene?
Genes are sections of DNA that carry instructions your cells use to make molecules or guide processes in the body. Some genes provide the directions for making proteins, the cell components that do much of the work. Other genes are mainly involved in controlling when certain processes happen, where they happen, and how strongly they occur. Together, genes affect how the body develops and works, and they can also influence how you respond to food, stress, and medications.

Overview
CENPSGene function
What if the gene works
The CENPS gene helps your cells organize chromosomes so they separate properly during cell division. It also supports repair of damaged DNA, which helps cells stay stable.
Risk
What if the gene does not work
Changes in the CENPS gene can weaken the cell’s ability to repair damaged DNA and help chromosomes separate properly during cell division. Milder variants may partly reduce this support, while more severe variants can disrupt these processes more strongly.
Treatment
What does that mean for your treatment
No CENPS-specific treatment, management approach, or drug-selection strategy is currently established for people with a pathogenic variant in the CENPS gene.
Gene function
What if the gene works
Every time a cell divides, it has to keep its chromosomes organized and its DNA intact. The CENPS gene helps with both jobs. Its protein works in small teams that support accurate chromosome separation during cell division and steady DNA copying and repair.
The CENPS gene helps maintain the centromere, the chromosome region where the cell's division machinery attaches. This supports proper chromosome alignment and clean separation when one cell becomes two.
One role of the CENPS gene is to help cells respond to DNA damage, especially when DNA copying pauses. It supports repair teams that stabilize the area so copying can continue in an orderly way.
During cell division, its protein works with partner proteins to manage stretches of DNA that are hard to copy. This helps keep chromosome structure steady while the cell prepares to divide.
What is a variant?
A genetic variant is a small difference in the DNA sequence within 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 the function of a gene more significantly and may contribute to or cause a genetic condition.
Genetic variants
What if the gene does not work
Variants in the CENPS gene can affect protein function by making the CENPS protein less stable, shortening it, or weakening how it binds to partner proteins involved in DNA repair and chromosome handling during cell division. Milder variants may leave some activity in place, while more severe variants can greatly reduce the amount of working protein or stop it from being made. This range of effects can lead to a partial or more marked loss of normal cell repair processes.
How variants are linked to conditions
Current evidence on how variants in the CENPS gene are linked to conditions is still developing, and this gene does not yet have a broadly confirmed connection to one specific health condition. If you have a reported CENPS variant or a confirmed CENPS-related diagnosis, your doctor or genetic counselor can explain what that result may mean for you and your family.
A variant is not necessarily a diagnosis
Genetic variants are a routine part of human biology and are widely present in the general population. Most do not directly affect health and instead reflect natural human variation. For many genes, carrying a variant associated with a condition indicates a possible link rather than a certain diagnosis, especially when several genes and environmental factors are involved. In some situations, though, a single well-characterized variant in a particular 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 CENPS gene. If a change in CENPS has been found in your family or on genetic testing, a doctor or genetic counselor can help explain what it may mean for your personal risk.
Inheritance of CENPS variants
CENPS-related conditions reported so far follow an autosomal recessive inheritance pattern, which explains how CENPS gene variants are inherited in families. This means a person usually needs to inherit two altered copies of the CENPS gene, one from each parent, to be affected. When both parents carry one variant, each pregnancy has a 25% chance of an affected child, a 50% chance of a child who is a carrier, and a 25% chance of a child with two working copies. Sons and daughters are affected at similar rates.
What does my CENPS result mean for my family?
Changes in the CENPS gene are linked to a rare inherited condition in a recessive pattern, which means close relatives may be carriers even if they have no symptoms. Brothers and sisters could also be affected if they inherited the same changed copy from both parents. For family members, the main question is often whether they carry the variant or could pass it on to children.
Genetic information
Genetic testing
How you find out about variants
To look for changes in the CENPS gene, doctors use genetic testing for CENPS variants on a blood sample or saliva sample. A lab reads your DNA and compares it with the usual sequence to spot variants. Results may show a variant that helps explain a health condition, or no relevant change.
When should I consider getting a genetic test?
There isn’t yet a broadly established reason for most people to have CENPS tested on its own. Testing decisions are usually made with a doctor or genetic counselor based on personal symptoms, family history, or broader gene panel testing for a suspected inherited condition.
A genetic result is only one part of your health story
A genetic result can provide useful insight, but how much it reveals depends on the condition and on the type of variant involved. Over time, many factors shape how the body functions, including lifestyle, environment, age, and medical history. For some conditions, especially those influenced by many genes, genetic information offers context rather than certainty and is best considered alongside other parts of care. In other situations, a genetic result may give 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 your body responds to medicines. Small differences in genes can change how a drug is absorbed, broken down, moved through the body, or how strongly it acts at its target. This helps explain why the same medication may work well for one person, have less effect in another, or cause more side effects in someone else.
What is Pharmacogenetics?
Pharmacogenetics examines how differences in a person’s genes can affect the way they respond to medicines. It studies links between genes and medications to help explain why the same treatment may work differently in different people. With many drugs, genes can influence how strongly a medicine works or how the body handles it. This information can support more informed and more individualized treatment decisions. More detailed information on this topic is available in the LearnHub.
Drugs influenced by the CENPS gene
When should I seek medical advice?
There is not yet a broadly confirmed role for this gene in guiding how medicines are chosen or used, so general questions about side effects, treatment response, or medication safety are best discussed with your doctor.
