The ANKRD26 gene helps control how bone marrow cells develop into platelets, which are the blood cells that help stop bleeding. This gene plays an important role in keeping platelet production balanced. If you carry a harmful variant, you may have lifelong low platelet counts with easy bruising, nosebleeds, or heavy periods. Some people with variants in the ANKRD26 gene also have a higher chance of certain myeloid blood conditions, including leukemia.
What is a gene?
Genes are stretches of DNA that give your cells instructions for making molecules or managing activities in the body. Some genes hold the directions for producing proteins, the parts of cells that do much of the work. Other genes mainly regulate when certain processes happen, where they happen, and how active they are. Taken together, genes affect how the body develops and works, and they can also influence how you respond to food, stress, or medications.

Overview
ANKRD26Gene function
What if the gene works
The ANKRD26 gene helps control how early blood cells grow and mature, especially cells that later make platelets. Its protein supports bone marrow signals involved in normal platelet production.
Risk
What if the gene does not work
Variants in the ANKRD26 gene can range from milder to more severe and most often cause inherited low platelet counts, with bleeding from none to bruising or nosebleeds. Some variants also increase the chance of myeloid blood cancers, including leukemia.
Treatment
What does that mean for your treatment
No ANKRD26-specific treatment or drug selection approach is currently established. In research, the ANKRD26 gene is being studied as a possible biomarker and cancer growth signal in some settings, but this has not changed routine treatment.
Conditions associated with ANKRD26
Gene function
What if the gene works
In blood-forming tissues, the ANKRD26 gene helps cells handle growth signals and mature in a controlled way. Its protein sits near the inner cell membrane, where it helps organize messages that guide normal cell behavior. This helps explain how the ANKRD26 gene supports normal platelet production.
The ANKRD26 gene helps cells pass along messages from growth receptors at the cell surface. Its protein sits near the inner cell membrane and helps signaling steps happen in the right place.
In bone marrow, the ANKRD26 gene helps regulate the development of megakaryocytes, the large cells that make platelets. It supports their response to thrombopoietin, a body signal that guides platelet production.
Its protein has ankyrin repeats, common structures that help proteins attach to other proteins. This allows the ANKRD26 gene’s protein to bring signaling partners together during normal cell activity.
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 reacts to environmental influences. Many variants do not have any noticeable effect and are simply part of natural genetic variation. In some situations, 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
Most ANKRD26 gene variants linked to disease sit in a control region rather than the protein coding part, so the gene stays too active in developing cells that make platelets. This ongoing overactivity can disrupt signaling needed for normal megakaryocyte maturation and platelet release. Some variants only partly weaken this control, while more disruptive variants may cause stronger misregulation and, in some families, earlier or more marked thrombocytopenia.
How variants are linked to conditions
Variants in the ANKRD26 gene cause ANKRD26-related thrombocytopenia, an inherited low platelet condition that may show up as easy bruising, nosebleeds, or low platelet counts on routine blood tests. This ANKRD26 gene condition is also linked to a higher chance of certain blood cancers, especially myelodysplastic syndrome and acute myeloid leukemia. Many people have mild day to day symptoms, while the platelet pattern and family history help doctors recognize the diagnosis.
A variant is not necessarily a diagnosis
Genetic variants are common in the general population and are a normal feature of human biology. Most have no 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 multiple genes and environmental factors are involved. 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?
For ANKRD26, the inherited gene change is the main reason for the condition, and there is not enough evidence that lifestyle changes meaningfully lower that risk. Bleeding problems can be more likely with medicines that affect platelets, such as aspirin, and some families also have a higher chance of blood cancers, so ongoing medical follow-up matters.
Inheritance of ANKRD26 variants
ANKRD26-related conditions usually follow an autosomal dominant inheritance pattern, which means a variant in one copy of the ANKRD26 gene can be enough to cause the condition. In practical terms, how ANKRD26 variants are inherited is often straightforward: a parent with the variant has a 50% chance of passing it on in each pregnancy. Sons and daughters can inherit it equally. This pattern is best established for ANKRD26-related thrombocytopenia, an inherited tendency to have a low platelet count.
What does my ANKRD26 result mean for my family?
A harmful change in the ANKRD26 gene is usually passed through families in a dominant way, so close relatives such as a parent, brother, sister, or child may also have it. For many, this can mean lifelong low platelets, easy bruising or nosebleeds, and in some families a higher chance of certain blood cancers. Because of that, family members may want to learn whether the same gene change is present in them.
Genetic information
Genetic testing
How you find out about variants
Genetic testing for ANKRD26 variants usually uses a blood or saliva sample. A lab reads the DNA in the ANKRD26 gene to look for changes, either across the full gene or for a known family variant, which can help clarify whether an inherited ANKRD26 gene variant is present.
When should I consider getting a genetic test?
Consider genetic testing for the ANKRD26 gene if you or close relatives have lifelong low platelet counts, easy bruising, frequent nosebleeds, or unusual bleeding after surgery or dental work. Testing can also help explain a family history of certain blood cancers and clarify whether low platelets are inherited rather than caused by something else.
A genetic result is only one part of your health story
A genetic result can provide useful insight, but what it tells you depends on the condition and the type of variant involved. Lifestyle, environment, age, and medical history all shape how the body functions over time. For some conditions, especially those influenced by many genes, genetic information offers context rather than certainty and is best understood together with 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 broken down, how strongly it acts, or how sensitive your body is to it. This helps explain why the same medication may work well for one person but less well for another, or why side effects can be milder or more noticeable. These differences are common and are one part of the bigger picture, along with age, other health conditions, and other medicines.
What is Pharmacogenetics?
Pharmacogenetics looks at how differences in genes can shape the way a person responds to medication. It examines relationships between genes and drugs to help explain why the same treatment may work differently from one person to another. With many medicines, genes affect both how the body processes a drug and how strong its effects are. This information can help support more informed, individualized treatment decisions.

Drugs influenced by the ANKRD26 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 which side effects are more likely. For any concerns about your health, symptoms, or medications, it is best to speak with your doctor.
History
ANKRD26 entered medical genetics through families with inherited low platelet counts that did not fit better known causes. Initially understood only through visible traits, later recognized as tied to a specific gene, these families helped researchers map the condition to chromosome 10. In 2011, studies identified variants in the ANKRD26 gene as the cause of what is now called ANKRD26 related thrombocytopenia. From these first observations, research expanded steadily, linking this finding to a clearer genetic diagnosis for some people with lifelong mild to moderate thrombocytopenia. Over time, scientists also recognized that certain families carrying variants in the ANKRD26 gene could have a higher chance of blood related conditions, which further shaped clinical awareness.
