The ANKRD22 gene helps make a protein that appears to influence how cells grow, send signals, and respond to stress. If it does not work as expected, these cell behaviors may become less controlled. This gene plays an important role in research on cancer and inflammation, where changes in ANKRD22 have been linked to differences in tumor behavior and immune activity.
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 are used mainly to control when certain processes happen, where they happen, and how active they are. Taken together, genes affect how the body grows and works, and they can also influence how you respond to food, stress, and medicines. For a deeper look at this topic, you can find more in LearnHub.
Overview
ANKRD22Gene function
What if the gene works
The ANKRD22 gene makes a protein with ankyrin repeats, a common structure that helps proteins interact. It appears to support cell signaling and how some cells respond to stress.
Risk
What if the gene does not work
Changes in the ANKRD22 gene may reduce or alter the ANKRD22 protein, which can affect how cells pass signals between proteins. Milder and more severe variants can leave different amounts of function.
Treatment
What does that mean for your treatment
No treatment or drug choice is currently guided by pathogenic variants in the ANKRD22 gene. The ANKRD22 gene is being studied mainly as a possible biomarker and research target in some cancers, rather than as a gene with guideline-based treatment decisions.
Gene function
What if the gene works
Inside your cells, the ANKRD22 gene supports routine communication between proteins. It makes a protein that mainly acts as a connector, helping different cell parts work together in an orderly way. This helps explain how the ANKRD22 gene contributes to everyday cell activity.
The ANKRD22 gene makes a protein with ankyrin repeat sections, which are common shapes that help proteins bind to other proteins. These links help cells assemble small working teams for everyday tasks.
By helping proteins connect, the ANKRD22 gene supports signaling pathways, the message systems cells use to adjust activity and stay coordinated. This is part of what the ANKRD22 gene does in cells during normal day to day function.
What is a variant?
A genetic variant is a minor difference in a gene’s DNA sequence. These differences are common and help explain normal variation among people, including appearance, metabolism, and the way the body reacts to environmental influences. Many variants do not lead to any noticeable effect and are part of natural genetic diversity. At times, though, a variant changes how a gene works more significantly and can contribute to or cause a genetic condition.
Genetic variants
What if the gene does not work
Variants in the ANKRD22 gene can change the shape, stability, or amount of ANKRD22 protein a cell makes. Some changes are mild and mainly weaken how the protein interacts with other cell proteins, while more disruptive variants can shorten the protein or make it break down sooner. This is how ANKRD22 gene variants affect protein function, with effects ranging from subtle shifts in cell signaling to a clearer loss of normal protein activity.
How variants are linked to conditions
At this time, the ANKRD22 gene does not yet have a broadly confirmed link to a specific health condition, although research on how variants in the ANKRD22 gene may be linked to health conditions is still evolving. Anyone with a confirmed ANKRD22 gene finding should rely on guidance from their doctor or genetic counselor for personal interpretation.
A variant is not necessarily a diagnosis
Gene variants are a normal feature of human biology and are common throughout the general population. Most have no direct impact on health and simply reflect natural human diversity. For many genes, carrying a variant associated with a condition indicates a possible link rather than a definite diagnosis, especially when more than one gene and environmental factors are involved. In some situations, though, one 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 isn't yet broadly confirmed evidence on specific factors that increase or reduce health risk related to the ANKRD22 gene. If ANKRD22 is part of your test results, a doctor or genetic counselor can help explain what it may mean in the context of your personal and family history.
Inheritance of ANKRD22 variants
There is not yet a broadly confirmed, disease-specific Mendelian ANKRD22 gene inheritance pattern used in routine human genetics. Current evidence does not support describing ANKRD22 gene inheritance as clearly autosomal dominant, autosomal recessive, or X linked for an established inherited condition. The ANKRD22 gene is located on chromosome 10, which is an autosome, so each person inherits one copy from each parent.
What does my ANKRD22 result mean for my family?
There is not yet a broadly confirmed inheritance pattern tied to a specific, well-established health condition for ANKRD22, and this picture may become clearer as research grows. If you have a specific ANKRD22 result and want to understand what it could mean for relatives, a doctor or genetic counselor can explain it in the context of your family history and the exact finding.
Genetic information
Genetic testing
How you find out about variants
To look for changes in the ANKRD22 gene, genetic testing usually uses a blood or saliva sample and reads the DNA sequence. Genetic testing for ANKRD22 variants may be done as part of a multigene panel, exome sequencing, or genome sequencing. The report describes whether a variant was found and how it is classified.
When should I consider getting a genetic test?
There is not yet a broadly established, ANKRD22-specific clinical reason for genetic testing. Testing decisions are usually based on your personal health history, family history, and guidance from a doctor or genetic counselor.
A genetic result is only one part of your health story
Genetic results can provide useful insight, though how much they explain varies with the condition and the kind of variant found. Over time, the way the body functions is shaped by many factors, including lifestyle, environment, age, and medical history. With some conditions, particularly those affected by many genes, genetic information offers context rather than certainty and makes the most sense when considered with other parts of care. In other situations, a genetic finding may give a clear answer. For topics like medication response, these results can also help put personal experiences in context.
Pharmacogenetics
How variants shape your response to medicine
Genetic variation can affect how people respond to medicines. Small differences in DNA can change how the body absorbs, breaks down, transports, or responds to a drug. This helps explain why the same medication may work well for one person, seem less effective for another, or cause more side effects in someone else. These differences are common and are one part of the bigger picture, along with age, kidney and liver function, other medicines, and overall health.
What is Pharmacogenetics?
Pharmacogenetics examines how differences in a person’s genes can affect the way they respond to medications. It studies patterns 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 support more informed and more individualized treatment decisions.

Drugs influenced by the ANKRD22 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 how well they work. For medication side effects, questions about treatment changes, or general health concerns, it is best to speak with your doctor.
History
ANKRD22 entered the scientific literature during the genomics era, when researchers were systematically identifying and naming many previously uncharacterized human genes. Early work described it mainly as part of large gene mapping and sequencing efforts rather than as a gene with a well known clinical story. In recent decades, awareness of this gene’s role has grown as studies began linking ANKRD22 to patterns seen in several cancers, especially in research on tumor behavior and prognosis. As medical science evolved, so did understanding of this gene. More recent papers have explored how changes in ANKRD22 expression may relate to cancer growth, spread, and treatment response, which brought it more attention in laboratory and translational research.
