The ANO6 gene helps cells shift certain fats across their outer membrane, which is especially important for platelets when your body needs to form a blood clot. If it does not work properly, clotting can be less effective and some people may bruise easily or bleed longer after an injury or procedure. This gene also supports normal cell signaling in several tissues. Pathogenic variants in the ANO6 gene are best known for causing a rare inherited bleeding condition called Scott syndrome.
What is a gene?
A gene is a stretch of DNA that carries instructions your cells use to make molecules or regulate activities in the body. Some genes provide the information needed to make proteins, which are the parts of cells that do much of the work. Others mainly guide when, where, and how strongly certain processes take place. Together, genes affect how the body develops and works, and they can influence how you respond to food, stress, and medications.

Overview
ANO6Gene function
What if the gene works
The ANO6 gene helps cells move certain fats across their outer membrane when calcium levels rise. This supports normal blood clotting and other cell processes, including cell repair and bone development.
Risk
What if the gene does not work
People with more disruptive variants in the ANO6 gene can have Scott syndrome, a rare bleeding condition in which blood clots form less effectively. Milder variants may leave some ANO6 activity, so symptoms and severity can vary.
Treatment
What does that mean for your treatment
No treatment or drug choice is currently tailored specifically to a pathogenic or loss-of-function variant in the ANO6 gene. The ANO6 gene is being studied as a possible biomarker and drug target in cancer and blood clotting research, but this has not yet led to guideline-based care.
Conditions associated with ANO6
Gene function
What if the gene works
Your cells use the ANO6 gene to rearrange certain fats in the cell membrane when calcium signals arrive. This helps the membrane act like a changing message board, showing different signals at the right moment. It also supports normal platelet activity and other cell responses that depend on a flexible cell surface.
Inside the cell membrane, the ANO6 gene helps move certain fats from one side to the other when calcium levels rise. This reshuffling changes the membrane surface and helps cells respond to signals.
By exposing phosphatidylserine (a membrane fat used as a signal) on the outer surface, this gene helps cells communicate with nearby proteins and cells. This supports normal coordination between cells and their surroundings.
In platelets, the ANO6 gene helps create a surface that supports clotting proteins after platelet activation. This is part of how the ANO6 gene helps blood clotting in a controlled, timely way.
Its protein can also form a pathway that lets charged particles, including chloride, cross the membrane when calcium is present. This helps connect calcium signals to changes at the cell surface.
What is a variant?
A genetic variant is a small difference in the DNA sequence within a gene. These changes are common and are part of normal human diversity, such as differences in appearance, metabolism, or how the body responds to environmental influences. Many have no noticeable effect and simply reflect natural genetic variation. In some cases, though, a variant can affect a gene’s function more substantially and may contribute to or cause a genetic condition.
Genetic variants
What if the gene does not work
Variants in the ANO6 gene often reduce or switch off the protein, which can weaken its ability to move certain fats across the cell membrane after a calcium signal. Some changes mainly lower activity, while more severe variants can make the protein unstable, poorly placed in the cell, or absent altogether. At a cell level, these changes show how ANO6 gene variants affect blood clotting, and stronger loss of function is often linked to clearer Scott syndrome features.
How variants are linked to conditions
Pathogenic variants in the ANO6 gene cause Scott syndrome, a rare inherited bleeding condition. In people with this diagnosis, ANO6 gene variants linked to Scott syndrome can lead to easy bruising or bleeding that lasts longer than expected after injury, surgery, or dental work. This association is well established in human genetics. Other reported ANO6-related findings have not reached the same level of broad clinical agreement.
A variant is not necessarily a diagnosis
Genetic variants are a routine part of human biology and are widespread in the general population. Most do not directly affect health and simply reflect natural human diversity. For many genes, having a variant associated with a condition points to a possible link rather than a definite diagnosis, especially when several genes and environmental factors play a role. 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?
There isn't yet broadly confirmed evidence on specific factors that increase or reduce health risk related to ANO6. For the rare bleeding condition linked to ANO6, risk is mainly shaped by the inherited gene change itself rather than lifestyle factors. Anyone concerned about personal or family risk should speak with a doctor or genetic counselor.
Inheritance of ANO6 variants
Variants in the ANO6 gene linked to ANO6-related Scott syndrome are inherited in an autosomal recessive pattern. This means a person usually develops the condition only when they inherit two changed copies of the ANO6 gene, one from each parent. Parents who each carry one variant are typically unaffected carriers, and with each pregnancy they have a 25% chance of having an affected child. In practical terms, how variants of the ANO6 gene are inherited depends on both parents passing on the changed copy.
What does my ANO6 result mean for my family?
For ANO6, family meaning is usually discussed in the setting of a rare inherited bleeding condition that tends to run in families in a recessive pattern. This often means parents may be healthy carriers, and brothers or sisters could also have the condition or be carriers. Other relatives may want to learn whether the same gene change is present, especially if there is a family history of unusual bleeding or easy bruising.
Genetic information
Genetic testing
How you find out about variants
To look for variants in the ANO6 gene, doctors use ANO6 genetic testing on a blood sample, saliva sample, or cheek swab. This is how genetic testing for ANO6 variants works: a lab reads the gene’s DNA code and compares it with the usual sequence to identify variants. Results may show a disease causing variant, a benign variant, or a variant of uncertain significance.
When should I consider getting a genetic test?
Testing for changes in the ANO6 gene may be worth considering if there is unusual bleeding or easy bruising, especially when platelet testing suggests a rare inherited bleeding condition. It can also help clarify the cause when several relatives have similar bleeding problems.
A genetic result is only one part of your health story
A genetic finding can provide meaningful insight, but how much it explains varies depending on the condition and the kind of variant involved. Many factors, including lifestyle, environment, age, and medical history, shape how the body works over time. For some conditions, especially those influenced by many genes, genetic information offers context rather than certainty and is best understood alongside other parts of care. In other situations, a genetic result may give a clear answer. In areas like medication response, genetic results can help put individual experiences into perspective.
Pharmacogenetics
How variants shape your response to medicine
Genetic variation can affect how people respond to medicines. Small differences in genes can change how the body breaks down a drug, how strongly a drug reaches its target, or how sensitive someone is to side effects. This helps explain why the same treatment works well for one person but less well for another. These differences are common and can influence both how well a medicine helps and how well it is tolerated.
What is Pharmacogenetics?
Pharmacogenetics examines how differences in genes affect the way someone responds to medications. It looks at the relationship between genes and drugs to better explain why the same treatment may work differently from one person to another. For many medicines, genes influence how strong a drug’s effects are or how the body handles it. This information can help guide more informed and more individualized treatment choices.

Drugs influenced by the ANO6 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, so any concerns about medications, side effects, or your general health are best discussed with your doctor.
History
The ANO6 gene entered medical genetics through studies of a rare bleeding condition called Scott syndrome, in which platelets do not expose the usual surface signals needed for normal clotting. In the early 2010s, researchers linked Scott syndrome to changes in the ANO6 gene, also known as TMEM16F, giving a genetic explanation for a condition that had puzzled doctors for years. Initially understood only through visible traits, later recognized as tied to a specific gene, this finding connected platelet biology with a broader family of related genes. From these first observations, research expanded steadily. ANO6 was then studied in blood cells, bone, and cell membrane repair, which helped place it within a larger picture of how cells respond to calcium signals.
