The AK1 gene helps cells recycle energy, especially in red blood cells, muscles, and the brain. This gene plays an important role in keeping the body’s energy supply steady from moment to moment. If it does not work properly, some people develop a rare inherited anemia because red blood cells break down too easily, and a few may also have learning, movement, or seizure related symptoms.
What is a gene?
Genes are sections of DNA that hold instructions your cells use to make molecules or regulate activities in the body. Some genes carry the directions for producing proteins, the parts of cells that do the work. Others mainly help control when certain processes happen, where they happen, and how strongly they run. Taken together, genes affect how the body develops and works, and they can also shape how you respond to food, stress, or medications. More detailed information on this topic is available in the LearnHub.
Overview
AK1Gene function
What if the gene works
The AK1 gene helps cells recycle energy by balancing their main energy molecules. It supports steady function in tissues with high energy needs, including red blood cells and muscles.
Risk
What if the gene does not work
Variants in the AK1 gene can cause hemolytic anemia that may be mild or more severe. More disruptive variants can reduce enzyme activity further and, in some people, are linked to developmental or neurologic features.
Treatment
What does that mean for your treatment
For people with a pathogenic or loss of function variant in the AK1 gene, no treatment or drug choice specific to the AK1 gene is currently established. Care is usually supportive and guided by a person’s symptoms rather than the gene itself. The AK1 gene is also being studied in cell energy pathways and some cancers, but this has not yet changed routine treatment choices.
Conditions associated with AK1
Gene function
What if the gene works
Your cells are constantly using and refilling small energy molecules to keep everyday processes going. The AK1 gene helps manage this quick energy trade so energy stays available from moment to moment. Understanding what the AK1 gene does in cells helps explain how many cells keep working smoothly during ordinary daily demands.
The AK1 gene helps cells convert ADP, a partly used energy molecule, into ATP, the cell’s main usable energy source, while also making AMP. This reversible swap lets cells recycle energy quickly as demands rise and fall.
By balancing ATP, ADP, and AMP, the AK1 gene helps keep a cell’s energy supply steady. These molecules also act as internal energy signals, so this balance helps cells match their work to the energy they have.
This rapid energy exchange supports routine tasks such as moving materials, maintaining cell structure, and powering basic cell activity. It is most helpful in cells that need fast, efficient energy handling from one moment to the next.
What is a variant?
A genetic variant is a minor change in a gene’s DNA sequence. These changes are common and are part of normal human diversity, including differences in appearance, metabolism, or the way the body responds to environmental influences. Many variants do not have any noticeable effect and simply represent natural genetic variation. At times, though, a variant can change how a gene works to a greater extent and may contribute to or cause a genetic condition.
Genetic variants
What if the gene does not work
Variants in the AK1 gene can change the shape, stability, or amount of the adenylate kinase 1 protein, so cells may have less enzyme activity or none at all. In practice, how AK1 gene variants affect enzyme activity depends on the change: some missense variants leave partial activity, while disruptive variants, including some splice or stop variants, can markedly impair protein folding or shorten the protein. Lower residual activity is often linked to earlier or pronounced AK1 deficiency features.
How variants are linked to conditions
Variants in the AK1 gene cause adenylate kinase deficiency, a rare inherited condition most often linked to chronic nonspherocytic hemolytic anemia. This AK1 gene condition can show up with ongoing anemia from red blood cell breakdown, and some affected people have also been reported to have developmental delay or intellectual disability. The blood-related features are the most established part of the diagnosis.
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 have no direct impact on health and simply contribute to natural human diversity. For many genes, carrying a variant associated with a condition suggests a possible link rather than a definite diagnosis, especially when several genes and environmental factors are involved. In some cases, 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 AK1, risk is mainly shaped by inheritance rather than lifestyle. A child’s chance of having an AK1-related condition is higher when both parents carry a harmful AK1 change, and there is not enough evidence to say that diet, exercise, or other everyday habits meaningfully change that inherited risk.
Inheritance of AK1 variants
Variants in the AK1 gene linked to AK1-related adenylate kinase deficiency are inherited in an autosomal recessive pattern. This means a child usually inherits one altered copy of the AK1 gene from each parent, while parents with one altered copy are typically carriers. When both parents are carriers, each pregnancy has a 25% chance of an affected child, a 50% chance of a carrier child, and a 25% chance of a child who did not inherit either altered copy.
What does my AK1 result mean for my family?
Changes in the AK1 gene are linked to a rare inherited condition that usually runs in families in a recessive pattern. For family members, this often means parents can be healthy carriers, and brothers or sisters may also be affected or be carriers even if they feel well. Close relatives may want to learn whether the same AK1 change is present in the family.
Genetic information
Genetic testing
How you find out about variants
Genetic testing for AK1 variants usually uses a blood or saliva sample to read the AK1 gene and look for DNA changes. Results may show a benign variant, a variant of uncertain significance, or a pathogenic variant, which can help clarify whether an AK1 related condition is present in a person or family.
When should I consider getting a genetic test?
Consider testing if you or your child has ongoing inherited anemia caused by red blood cells breaking down too early, especially with a family history or no clear cause. Testing can help confirm whether a change in the AK1 gene is involved.
A genetic result is only one part of your health story
A genetic result can be helpful, but how much it reveals depends on the condition and the kind of variant involved. Many factors, including lifestyle, environment, age, and medical history, also influence how the body functions over time. For some conditions, especially those shaped 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 context.
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, moves it through the bloodstream, or responds to it at its target. This is common and can help explain why the same treatment works well for one person, works less well for another, or causes more side effects in someone who is more sensitive to it.
What is Pharmacogenetics?
Pharmacogenetics examines how differences in a person’s genes can affect their response to medications. It looks at relationships 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 how the body processes a drug or how strong its effects are. This information can support more informed, more personalized treatment choices.

Drugs influenced by the AK1 gene
When should I seek medical advice?
There isn’t yet a broadly confirmed role for this gene in guiding medication choice or dosing, so any questions about side effects, new symptoms, or whether a treatment is working are best discussed with your doctor.
