The TOMM6 gene helps build the gateway on the outer surface of mitochondria, the parts of cells that make energy. If it does not work as it should, mitochondria may struggle to bring in the proteins they need, which can disrupt normal cell function and energy production. Every cell in your body uses this gene to support these basic energy processes. TOMM6 is mainly known in research settings and has not become a high profile gene in public culture.
What is a gene?
Genes are stretches of DNA that hold instructions your cells use to make molecules or direct processes in the body. Some genes carry the instructions for making proteins, the parts of cells that do much of the work. Other genes mainly 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.

Overview
TOMM6Gene function
What if the gene works
The TOMM6 gene helps move proteins into mitochondria, the parts of cells that make energy. This supports normal cell function and healthy energy use.
Risk
What if the gene does not work
Changes in the TOMM6 gene can range from milder to more severe and may weaken the cell’s mitochondrial import machinery. When TOMM6 does not work well, fewer proteins are moved into mitochondria, which can disrupt energy production inside cells.
Treatment
What does that mean for your treatment
For a pathogenic or loss-of-function variant in the TOMM6 gene, no TOMM6-specific treatment or management approach is currently established.
Gene function
What if the gene works
Your cells need a steady flow of proteins into mitochondria, the parts that help turn food into usable energy. The TOMM6 gene supports the import system on the mitochondrial surface that moves these proteins into place. This helps mitochondria stay supplied for routine cell work.
Protein import into mitochondria is one of the main jobs supported by the TOMM6 gene. It helps proteins pass through a gateway on the mitochondrial surface so these structures have the parts they need.
Its protein is part of the TOM complex (the main entry gate for proteins at the mitochondrial surface). This small component helps the gate stay organized so incoming proteins can be directed into mitochondria.
By supporting protein entry, the TOMM6 gene helps mitochondria carry out routine tasks. This includes receiving many protein building blocks needed for energy production and other everyday mitochondrial work.
What is a variant?
A genetic variant is a minor difference in the DNA sequence within a gene. These changes are common and help shape normal human diversity, including differences in appearance, metabolism, and the way the body responds to environmental influences. Many do not have any noticeable effect and simply represent natural genetic variation. In some situations, though, a variant changes how a gene works more significantly and may contribute to, or cause, a genetic condition.
Genetic variants
What if the gene does not work
Variants in the TOMM6 gene can lower the amount of TOMM6 protein a cell makes or change its shape, so it joins the mitochondrial entry channel less effectively. How TOMM6 gene variants affect mitochondrial protein import depends on the specific DNA change. Milder variants may only slightly weaken this protein gateway, while more severe variants can make the protein unstable, very short, or unable to support normal protein movement into mitochondria, the parts of cells that help make energy.
How variants are linked to conditions
Current research has not broadly confirmed a specific health condition caused by variants in the TOMM6 gene, and understanding of how variants in the TOMM6 gene are linked to conditions may evolve with further study. Anyone with a confirmed TOMM6-related finding should rely on guidance from their doctor or genetic counselor to understand what it may mean for their health.
A variant is not necessarily a diagnosis
Genetic variants are common across the general population and are a normal feature of human biology. Most do not directly affect health and instead reflect natural variation among people. For many genes, having a variant associated with a condition suggests a possible link rather than a definite diagnosis, particularly when several genes and environmental influences also 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 is not yet broadly confirmed evidence on specific factors that increase or reduce health risk related to the TOMM6 gene. If TOMM6 appears on a genetic test, its meaning is usually interpreted alongside other genes and your personal and family health history.
Inheritance of TOMM6 variants
There is not yet a broadly confirmed disease-specific inheritance pattern for the TOMM6 gene, so TOMM6 gene inheritance is not currently described as a well-established autosomal dominant, autosomal recessive, or X-linked condition. The TOMM6 gene is located on chromosome 16, which is an autosome. That means each person inherits one copy from their mother and one copy from their father.
What does my TOMM6 result mean for my family?
There is not yet a broadly confirmed inheritance pattern tied to a specific health condition for TOMM6. If you have a TOMM6 result and want to understand what it could mean for relatives, a doctor or genetic counselor can help explain it in the context of your personal and family history.
Genetic information
Genetic testing
How you find out about variants
To find out whether you carry a variant in the TOMM6 gene, a lab can analyze DNA from a saliva sample or blood test. Genetic testing for TOMM6 variants reads the gene’s code and compares it with the usual sequence to identify changes that a clinician interprets alongside your health and family history.
When should I consider getting a genetic test?
There is not yet a broadly established TOMM6-specific reason for genetic testing in routine care. Testing decisions are usually based on your symptoms, family history, and whether a doctor or genetic counselor thinks a broader genetic test could help.
A genetic result is only one part of your health story
Genetic findings can be informative, but how much they explain varies by the condition and the specific variant involved. Over time, many other factors also shape how the body functions, 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 best interpreted alongside other parts of care. In other situations, a genetic result can offer a clear answer. In areas like medication response, genetic results may 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 inherited differences can change how the body breaks down a drug, moves it through the body, or responds to it at its target. This helps explain why the same treatment may work well for one person, do less for another, or cause more side effects in someone else. These differences are common and are one of several reasons medication response can vary from person to person.
What is Pharmacogenetics?
Pharmacogenetics examines how differences in a person’s genes can affect the way they respond to medicines. By looking at connections between genes and drugs, it helps explain why the same treatment may work differently from one person to another. For many medicines, genes influence how strongly a drug works or how the body breaks it down. This information can support treatment decisions that are more informed and more individualized.

Drugs influenced by the TOMM6 gene
When should I seek medical advice?
There is not yet a broadly confirmed role for this gene in guiding medicine choices, so questions about side effects, new symptoms, or how well a treatment is working are best discussed with your doctor.
