The CDK10 gene helps control how cells grow, divide, and mature during early development. If it does not work properly, normal growth and body development can be disrupted, which may contribute to a rare inherited condition with short stature, developmental delay, distinctive facial features, and spine or hearing differences. The protein made by this gene also supports tiny hairlike cell parts called cilia, which help cells sense and respond to their surroundings.
What is a gene?
Genes are stretches of DNA that hold instructions your cells use to make molecules or regulate processes in the body. Some genes carry the code for proteins, the parts of cells that do much of the work. Other genes mostly help direct when certain processes happen, where they take place, and how active they are. Together, genes affect how the body develops and works, and they can also influence how you respond to food, stress, and medications.

Overview
CDK10Gene function
What if the gene works
The CDK10 gene helps control how cells grow and divide. It also supports normal development and the upkeep of tiny cell structures called cilia, which help cells sense their surroundings.
Risk
What if the gene does not work
When both copies of the CDK10 gene do not work well, people can have a condition affecting growth and development, often with short stature and distinctive skeletal features. Milder and more severe variants can affect timing and severity.
Treatment
What does that mean for your treatment
No CDK10-specific treatment or drug choice is currently established. Care is based on the person's symptoms and daily needs rather than on a medicine aimed at the CDK10 gene itself. The CDK10 gene is being studied in cancer research as a possible biomarker and drug target, but this has not led to guideline-based treatment decisions.
Gene function
What if the gene works
Your cells rely on the CDK10 gene to keep growth and routine activity well timed. It makes a protein that works like a controlled switch, adding phosphate groups, which are small chemical tags that change how other proteins behave. This helps cells respond to signals, organize their inner framework, and move through normal growth steps. Together, this shows what the CDK10 gene does in the body each day.
The CDK10 gene helps guide how cells move through normal growth and division steps. This supports steady cell renewal in tissues that regularly replace older cells.
Its protein is a kinase, which means it adds phosphate groups, small chemical tags, to selected proteins. This can change how those proteins act and helps pass signals inside the cell.
CDK10 activity helps tune how strongly cells react to everyday growth cues. This supports balanced gene activity and more coordinated cell behavior.
Working with the FAM58A gene product Cyclin M, CDK10 helps organize the cell's inner support fibers. This supports cell shape, movement, and control of the primary cilium, a small antenna-like projection on the cell surface.
What is a variant?
A genetic variant is a minor difference in the DNA sequence within a gene. These differences are common and help shape normal human diversity, including variation in appearance, metabolism, and the way the body responds to environmental factors. Many have no visible effect and are simply part of the usual range of genetic variation. At times, though, a variant changes how a gene works more substantially and can contribute to, or directly cause, a genetic condition.
Genetic variants
What if the gene does not work
Variants in the CDK10 gene can alter the protein’s shape, reduce how much of it is made, or weaken its link with cyclin M, which can disrupt cell signaling and the cell cycle (the process cells use to grow and divide). More disruptive variants may leave little or no working protein, while milder variants may preserve some activity. In people with a CDK10 related condition, this range in CDK10 gene variant effects can influence how early features appear and how marked they are.
How variants are linked to conditions
When a person inherits two disease-causing variants in the CDK10 gene, this can cause a rare developmental condition often called Al Kaissi syndrome. Reported features include slow growth, developmental delay, spine or rib differences, and distinctive facial features. Research on CDK10 gene variants linked to developmental delay and growth problems supports this as the gene’s main well-established condition association.
A variant is not necessarily a diagnosis
Genetic variants are a routine part of human biology and are widely found in the general population. Most do not directly affect health and instead reflect normal human diversity. For many genes, carrying a variant associated with a condition suggests a possible link rather than confirming a diagnosis, especially when several genes and environmental factors also play a role. In some situations, though, a single well understood 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 CDK10 gene. For families with a known CDK10 gene change, personal risk depends mainly on the exact variant and whether it was inherited from one or both parents.
Inheritance of CDK10 variants
CDK10-related conditions are inherited in an autosomal recessive pattern. In practical terms, how CDK10 gene variants are inherited usually means a child must receive one altered copy of the CDK10 gene from each parent to be affected. Parents who each carry one variant are often unaffected themselves, and with each pregnancy there is a 25% chance the child will inherit both altered copies, a 50% chance the child will be a carrier, and a 25% chance the child will inherit neither altered copy.
What does my CDK10 result mean for my family?
For families with a disease-causing CDK10 result linked to the recognized CDK10-related condition, relatives may also carry the same gene change even if they do not have symptoms. Brothers and sisters could be affected or be carriers, and parents are often carriers. Other close family members may also carry the change, so the meaning for relatives can be important when family planning is being considered.
Genetic information
Genetic testing
How you find out about variants
CDK10 genetic testing looks for changes in the CDK10 gene using a blood sample, saliva, or sometimes a cheek swab. A lab reads the gene’s DNA to check for variants and compares them with changes already linked to a genetic condition. Results may show a disease causing variant, a harmless variant, or a finding that is still unclear.
When should I consider getting a genetic test?
Genetic testing for the CDK10 gene may be worth considering when a child has unexplained developmental delay along with poor growth, short stature, hearing loss, or differences affecting the spine, ears, or face. It can also help when similar features run in the family or when doctors are trying to confirm a CDK10-related condition.
A genetic result is only one part of your health story
Genetic findings can provide useful insight, but how much they reveal depends on the condition and on the type of variant involved. How the body functions over time is also shaped by many factors, including lifestyle, environment, age, and medical history. For some conditions, especially those influenced by many genes, genetic information provides context rather than certainty and is best understood together with 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. This happens because your body may absorb, break down, transport, or respond to a drug a little differently from someone else’s. These differences are common and can influence how well a treatment works or how sensitive a person is to side effects.
What is Pharmacogenetics?
Pharmacogenetics looks at how genetic differences can shape a person’s response to medications. It studies links between genes and drugs to better 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 handles it. This information can help support more informed, individualized treatment decisions. You can read more about this topic in the LearnHub.
Drugs influenced by the CDK10 gene
When should I seek medical advice?
There is not yet a broadly confirmed role for this gene in guiding medication use, so general questions about side effects, treatment choices, or drug response are best discussed with your doctor. Some early research has looked at CDK10 in breast cancer, where lower CDK10 activity in tumor cells may be linked with less response to some hormone treatments, but this is not part of routine prescribing guidance.
History
The CDK10 gene entered the scientific literature in the 1990s as researchers were mapping members of the cyclin dependent kinase family. At first, it was mainly of interest within basic genetics and cell biology research rather than public health discussions. In recent decades, awareness of this gene’s role has grown as studies linked changes in the CDK10 gene to a rare inherited condition called STAR syndrome and explored its relevance in cancer research. Over time, descriptions became more precise as improved DNA testing made it easier to connect specific variants with human health findings. Unlike genes that became widely known through major public stories, the history of the CDK10 gene has developed mostly through steady laboratory and clinical research.
