The GOT1 gene gives cells instructions for an enzyme that helps process amino acids and supports energy flow inside the cell. The protein made by this gene helps your cells keep important chemical levels in balance, especially in the brain. If the gene does not work properly, that balance can be disrupted. Rare inherited variants in the GOT1 gene have been linked to seizures starting early in life and developmental delay.
What is a gene?
A gene is a section of DNA that carries instructions your cells use to make molecules or manage processes in the body. Some genes provide the directions for producing proteins, which are the parts of cells that do much of the work. Other genes mostly help regulate 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 influence how you respond to food, stress, or medicines. For a deeper look at this topic, you can find more in the LearnHub.
Overview
GOT1Gene function
What if the gene works
The GOT1 gene helps make an enzyme that helps cells process amino acids and balance energy by shuttling materials between the cell fluid and mitochondria.
Risk
What if the gene does not work
Variants in the GOT1 gene can range from milder to more severe and may reduce how well cells transfer amino groups, a key step in handling amino acids and balancing aspartate and glutamate. This can disrupt related cell chemistry.
Treatment
What does that mean for your treatment
No GOT1-specific treatment or drug selection approach is currently established in clinical guidelines. Care is based on a person’s symptoms and overall diagnosis, not on a variant in the GOT1 gene itself. In research, the GOT1 gene is being studied as a possible drug target in some cancers, especially pancreatic cancer, because tumor cells may depend on this pathway.
Gene function
What if the gene works
Your cells use the GOT1 gene every day to manage amino acids and keep energy flowing where it is needed. Its protein helps cells swap small chemical parts between nutrients, which supports routine work in many tissues. Understanding how the GOT1 gene supports amino acid balance and cell energy makes its day to day role easier to see.
The GOT1 gene helps cells convert one amino acid into another form that can be used right away. This keeps the supply of key amino acids balanced for normal cell work.
Its protein supports a built in transfer system that helps cells move energy from the fluid part of the cell to the mitochondria (the parts that make most energy). This helps fuel be used more efficiently.
By making aspartate, the GOT1 gene helps provide a basic ingredient cells use to build proteins and genetic material. This supports growth, repair, and other routine tasks.
What is a variant?
A genetic variant is a small alteration in the DNA sequence of a gene. These changes are common and help account for normal human diversity, including differences in appearance, metabolism, or how the body responds to environmental influences. Many variants do not cause any noticeable effect and simply represent natural genetic variation. In some situations, however, a variant can change how a gene functions more substantially and may contribute to or cause a genetic condition.
Genetic variants
What if the gene does not work
Variants in the GOT1 gene can change the shape or stability of the GOT1 enzyme, weaken binding to pyridoxal phosphate (a vitamin B6 derived helper molecule), or disrupt pairing with another copy of the protein, lowering enzyme activity. Milder GOT1 gene variants may leave partial activity, while more disruptive variants can markedly reduce or abolish it. These changes can disturb how cells handle key amino acids such as aspartate and glutamate.
How variants are linked to conditions
Variants in the GOT1 gene do not yet have a broadly confirmed link to a specific health condition, though research on GOT1 gene variants and health conditions is still developing. Anyone with a confirmed result involving the GOT1 gene should use their doctor’s or genetic counselor’s advice to understand what it means for them.
A variant is not necessarily a diagnosis
Genetic variants are a routine part of human biology and are common throughout the general population. Most do not have a direct effect 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 several genes and environmental factors also contribute. 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 is not yet broadly confirmed evidence on specific factors that increase or reduce health risk related to the GOT1 gene. If testing shows a change in GOT1, personal risk usually depends more on the exact change and the health issue being evaluated than on any known lifestyle factor.
Inheritance of GOT1 variants
There is not yet a broadly confirmed Mendelian pattern for how GOT1 gene variants are inherited in relation to a specific inherited condition. As research stands, the answer to how GOT1 gene variants are inherited is still being clarified rather than tied to a well-established autosomal dominant, autosomal recessive, or X-linked condition. The GOT1 gene is located on chromosome 10, which is an autosome. That means you inherit one copy of the GOT1 gene from each parent.
What does my GOT1 result mean for my family?
There isn't yet a broadly confirmed inheritance pattern tied to a specific condition for GOT1, though this understanding can change as research develops. If you have a specific GOT1 result and questions about what it could mean for your family, a doctor or genetic counselor can explain it in the context of your personal and family history.
Genetic information
Genetic testing
How you find out about variants
Genetic testing for GOT1 variants uses a blood or saliva sample to read the GOT1 gene and look for DNA changes. It can show whether you carry a variant in the GOT1 gene, but the result only has medical meaning when the finding is interpreted in the context of established clinical evidence.
When should I consider getting a genetic test?
There is not yet a broadly established, GOT1-specific clinical reason for testing. Testing decisions are best made with a doctor or genetic counselor based on your symptoms, medical findings, and family history.
A genetic result is only one part of your health story
A genetic result can be informative, yet what it can tell you varies with the condition and the kind of variant present. Over time, many factors shape how the body works, including lifestyle, environment, age, and medical history. For some conditions, especially those affected by many genes, genetic information provides context rather than certainty and is most useful when considered alongside 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 personal experiences into perspective.
Pharmacogenetics
How variants shape your response to medicine
Genetic variation can affect how people respond to medicines. Two people taking the same treatment may process it differently, so one may get the expected benefit while another may notice less effect or be more sensitive to side effects. This is a normal part of human variation and reflects small differences in how the body absorbs, breaks down, transports, or responds to a drug.
What is Pharmacogenetics?
Pharmacogenetics examines how genetic differences affect the way people respond to medications. It studies links between genes and drugs to help explain why the same treatment can work differently from one person to another. For many medicines, genes influence how strongly a drug works or how the body handles it. This information can support more informed and more individualized treatment decisions.

Drugs influenced by the GOT1 gene
When should I seek medical advice?
There is not yet a broadly confirmed role for this gene in guiding medication choices, so talk with your doctor about any medicine concerns, especially if side effects start after beginning, stopping, or changing a treatment.
History
GOT1 entered medical history through the study of aspartate aminotransferase, an enzyme long measured in blood tests. In the 1950s, doctors began using AST levels to help assess liver injury and heart damage, years before the gene itself was mapped in detail. Early laboratory work showed that this enzyme existed in more than one form, which helped researchers separate the cytosolic form linked to the GOT1 gene from the mitochondrial form linked to GOT2. Building on this early work, scientists connected older enzyme chemistry findings to specific genes as human genetics advanced. Over time, descriptions became more precise as gene mapping and sequencing clarified where GOT1 sits in the genome. Its history is quieter than that of some famous genes, but it is closely tied to the development of modern clinical blood testing.
