The ME1 gene helps cells turn one fuel molecule into another while making NADPH, a form of chemical energy that supports fat production and helps protect cells from everyday stress. This gene plays an important role in energy balance and in how tissues such as the liver and body fat handle nutrients. If the gene does not work properly, cells may struggle with these tasks, and rare pathogenic variants have been linked to developmental and brain-related problems.
What is a gene?
Within your DNA, a gene is a stretch that carries instructions 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. Others are used mainly to regulate when certain processes happen, where they happen, and how active they are. Taken together, genes affect how the body develops and functions, and they can influence how you respond to food, stress, or medications.

Overview
ME1Gene function
What if the gene works
The ME1 gene helps cells turn malate into pyruvate and make NADPH, a small molecule used for energy balance. This supports fat production and helps protect cells from everyday chemical stress.
Risk
What if the gene does not work
More severe variants in the ME1 gene can cause a rare neurodevelopmental condition, often with developmental delay and sometimes seizures or movement problems. Milder variants may lead to fewer or later appearing features.
Treatment
What does that mean for your treatment
No treatment or medication choice linked to a pathogenic variant in the ME1 gene is currently established in clinical guidelines. The ME1 gene is being studied in cancer and metabolism research as a possible biomarker and drug target, but this has not yet changed routine care.
Gene function
What if the gene works
Inside your cells, the ME1 gene helps manage how nutrients are turned into useful fuel and building materials. It supports a key step in the cell fluid, where malate is converted into pyruvate. This process also makes NADPH, a helper molecule cells use for fat building and for protection against everyday chemical wear and tear.
The ME1 gene helps change malate into pyruvate in the cell fluid. This gives cells a flexible way to move material from one energy pathway to another during normal daily activity.
As it carries out this step, the ME1 gene helps make NADPH, a molecule that provides chemical power for many cell jobs. Cells use this power for making fats and keeping their internal balance steady.
Many cells use the ME1 gene as part of the normal process of making fatty acids, which are important for cell membranes and energy storage. This helps explain how the ME1 gene supports fat production and energy balance in the body.
The ME1 gene connects pathways that handle sugars, organic acids, and fats. By moving material between these routes, it helps cells adjust to changing nutrient needs.
What is a variant?
A genetic variant is a small difference in the DNA sequence of a gene. These changes are common and contribute to normal human diversity, including differences in appearance, metabolism, or how the body responds to environmental influences. Many have no noticeable effect and simply represent natural genetic variation. In some cases, though, a variant can change how a gene works more substantially and may contribute to or cause a genetic condition.
Genetic variants
What if the gene does not work
Exactly how ME1 gene variants affect enzyme activity depends on the change. Some missense variants alter the protein’s shape, making it less stable or less able to bind malate or NADP, a helper molecule the enzyme uses. More severe variants, including ones that add an early stop signal, can greatly reduce or eliminate protein production, causing a stronger loss of function at the cellular level.
How variants are linked to conditions
The ME1 gene does not yet have a broadly confirmed link to a specific health condition, although research on ME1 gene variants linked to conditions is still developing. If you carry a variant in the ME1 gene, its meaning is best understood alongside your personal health and family history with a doctor or genetic counselor.
A variant is not necessarily a diagnosis
Genetic variants are common and form a normal part of human biology. Most do not directly affect health and instead reflect natural human variation. For many genes, having a variant associated with a condition indicates a possible link rather than a certain diagnosis, especially when several genes and environmental influences are involved. In some situations, though, one well characterized variant in a specific gene can be 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 ME1 gene. ME1 can be part of a bigger picture that also includes other genes, age, sex, and everyday factors such as diet and activity, so personal risk is best reviewed with a doctor or genetic counselor.
Inheritance of ME1 variants
There is not yet a broadly confirmed, disease-specific Mendelian pattern for how ME1 gene variants are inherited, so ME1 gene inheritance is not described in the same clear way as classic dominant, recessive, or X-linked conditions. As research develops, this picture may become clearer. The ME1 gene is located on chromosome 6, which is an autosome, so you inherit one copy from each parent. That means any ME1 gene variant present in you would have come through one side of the family or the other, unless it arose as a new variant.
What does my ME1 result mean for my family?
There is not yet a broadly confirmed inheritance pattern tied to a specific, well-established condition for the ME1 gene, though this can become clearer as research grows. If you have a specific ME1 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 variant found.
Genetic information
Genetic testing
How you find out about variants
To look for changes in the ME1 gene, doctors use ME1 genetic testing on a blood or saliva sample. The lab reads the gene's DNA, often as part of a larger panel or exome test, and the report may show no variant, a benign variant, or a variant linked to disease.
When should I consider getting a genetic test?
There is not yet a broadly established, ME1-specific clinical reason for genetic testing in routine care. Testing decisions are usually based on your personal health history, family history, and whether a doctor or genetic counselor thinks a wider gene panel would be helpful.
A genetic result is only one part of your health story
A genetic result can be informative, but how much it reveals varies by the condition and the specific type of variant. Over time, many factors also influence how the body functions, including lifestyle, environment, age, and medical history. For some conditions, particularly those shaped by many genes, genetic information offers context rather than certainty and is best considered alongside other parts of care. In other situations, it may give a clear answer. In areas like medication response, genetic results can also help put personal experiences into 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, or responds to a drug, which helps explain why the same treatment works well for one person but less well for another. These differences are common and can influence how much benefit someone gets from a medication or how sensitive they are to side effects.
What is Pharmacogenetics?
Pharmacogenetics examines how differences in genes affect the way people respond to medicines. It studies relationships between genes and drugs to help explain why the same treatment may work differently from one person to another. For many medications, genes can influence both how strongly a drug works and how the body processes it. This information can support treatment decisions that are more informed and more individualized. More detailed information on this topic is available in the LearnHub.
Drugs influenced by the ME1 gene
When should I seek medical advice?
There is not yet a broadly confirmed role for this gene in guiding medication choice or response, so questions about side effects, new symptoms, or whether a treatment is right for you are best discussed with your doctor.
