The TMEM160 gene gives cells instructions for a small protein linked to mitochondria, the parts of cells that make most of your energy. This gene helps your body support steady energy production and manage cell stress. If TMEM160 does not work properly, cells may make energy less efficiently and may be more sensitive to oxidative stress, a type of wear and tear inside cells. Researchers are studying how this may affect tissues that need a lot of energy.
What is a gene?
Genes are stretches of DNA that hold instructions your cells use to make molecules or manage processes in the body. Some genes carry the directions for producing proteins, the parts of cells that do much of the work. Other genes mainly regulate when certain processes happen, where they take place, and how strongly they occur. Together, genes affect how the body develops and functions, and they can also shape how you respond to food, stress, or medications.

Overview
TMEM160Gene function
What if the gene works
The TMEM160 gene helps make a protein found in mitochondria, the parts of cells that produce energy. It appears to support normal mitochondrial activity and healthy cell balance.
Risk
What if the gene does not work
Changes in the TMEM160 gene can range from mild to more disruptive and may reduce TMEM160 protein activity to different degrees. Cells may then handle mitochondrial energy production and oxidative stress less effectively.
Treatment
What does that mean for your treatment
For people with a pathogenic or loss-of-function variant in the TMEM160 gene, no TMEM160-specific treatment or drug selection approach is currently established in clinical guidelines.
Gene function
What if the gene works
Inside many cells, the TMEM160 gene helps support routine work in mitochondria, the parts of cells that help turn food into usable energy. Its protein sits in a cell membrane and contributes to steady mitochondrial activity. This is part of how the TMEM160 gene supports day to day cell function.
The TMEM160 gene makes a protein that sits in the membrane of mitochondria, the parts of cells that help produce usable energy. In this position, it supports normal mitochondrial function and steady everyday cell activity.
What is a variant?
A genetic variant is a small change in the DNA sequence within a gene. These changes are common and are part of normal human diversity, including differences in appearance, metabolism, and how the body responds to environmental influences. Many variants do not have any noticeable effect and simply represent natural genetic variation. In some situations, though, a variant can more substantially change how a gene functions and may contribute to or cause a genetic condition.
Genetic variants
What if the gene does not work
Variants in the TMEM160 gene can change the protein’s amino acid sequence, shorten it, or reduce how much of it a cell makes. This helps explain how TMEM160 gene variants affect protein function: some milder variants may slightly alter protein stability or membrane placement, while more severe variants can markedly disrupt folding, shorten the protein, or prevent the full protein from being produced. These differences can lead to a range of functional effects at the cellular level.
How variants are linked to conditions
Variants in the TMEM160 gene do not yet have a broadly confirmed link to a specific health condition, so information on how TMEM160 gene variants are linked to conditions is still evolving. Anyone with a confirmed TMEM160-related diagnosis should rely on guidance from their doctor or genetic counselor rather than general information.
A variant is not necessarily a diagnosis
Genetic variants are a usual part of human biology and are widely found in the general population. Most do not directly affect health and instead reflect normal human diversity. For many genes, carrying a variant associated with a condition indicates a possible link rather than a certain diagnosis, especially when several genes and environmental factors play a role. Still, in some situations, a single well-characterized variant in a particular gene can be 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 the TMEM160 gene. If TMEM160 shows up on your genetic test report, a doctor or genetic counselor can help put it in context with your personal and family history.
Inheritance of TMEM160 variants
There is not yet a broadly confirmed inheritance pattern tied to a specific condition caused by the TMEM160 gene, so discussions of how TMEM160 gene variants are inherited remain limited. The TMEM160 gene is located on an autosome rather than a sex chromosome, which means you inherit one copy from your mother and one copy from your father. As research develops, a clearer disease specific pattern may be identified.
What does my TMEM160 result mean for my family?
There isn’t yet a broadly confirmed inheritance pattern tied to a specific health condition for TMEM160, though this understanding can change as research develops. If you have a specific TMEM160 result and questions about what it could mean for your family, 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 change in the TMEM160 gene, a TMEM160 gene test uses a blood or saliva sample to read the gene's DNA sequence. Results can show a known variant, no relevant variant, or a variant of uncertain significance, and clinicians interpret them alongside your personal and family history.
When should I consider getting a genetic test?
There isn't yet a broadly established TMEM160-specific reason for genetic testing in routine care. Decisions about testing are usually based on your personal health history, family history, and the reason testing is being considered, ideally with a doctor or genetic counselor.
A genetic result is only one part of your health story
A genetic result can be informative, but what it can tell you varies by the condition and the kind of variant involved. Lifestyle, environment, age, and medical history, among other influences, also shape how the body functions over time. In some conditions, especially those affected by many genes, genetic information offers context rather than certainty and is most useful when viewed alongside other parts of care. In other situations, a genetic result can give a clear answer. In areas such as 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. This helps explain why the same treatment may work well for one person, work less well for another, or cause more side effects in someone else. Part of the reason is that inherited differences can change how the body breaks down, moves, or responds to a drug. These differences are common and are one of several factors, along with age, kidney and liver function, and other medicines, that can shape treatment response.
What is Pharmacogenetics?
Pharmacogenetics examines how inherited genetic differences affect the way people respond to medicines. It studies gene-drug patterns to help explain why the same treatment can work differently in different people. With many medicines, genes influence either how strongly a drug works or how the body handles it. This information can support more informed, personalized treatment decisions. More detail on this subject is available in the LearnHub.
Drugs influenced by the TMEM160 gene
When should I seek medical advice?
There is not yet a broadly confirmed role for this gene in guiding medication choice or dose. If you have side effects, trouble getting the expected benefit from a medicine, or questions about how your medicines fit with your health history, talk with your doctor or pharmacist.
