The TMEM87A gene gives cells instructions for a membrane protein involved in the cell’s internal transport system. The protein made by this gene helps your cells sort and move certain proteins to the right place. If the TMEM87A gene is not working properly, some cell signals and routine cell tasks may become less organized, which can affect how tissues function. This gene is mainly known in research rather than through celebrity or media attention.
What is a gene?
Genes are stretches of DNA that give your cells instructions for making molecules or directing processes in the body. Some genes carry the information needed to make proteins, the parts of cells that do much of the work. Other genes mainly control when certain processes happen, where they take place, and how strongly they run. Together, genes affect how the body develops and works, and they can also shape how you respond to food, stress, and medications. To explore this subject in more detail, you can learn more in the LearnHub.
Overview
TMEM87AGene function
What if the gene works
The TMEM87A gene makes a membrane protein that helps organize transport within cells. This protein appears to support how some proteins move to the cell surface and through internal compartments.
Risk
What if the gene does not work
Depending on the variant, the TMEM87A gene may keep some function or lose more of it. This can disrupt ion movement and the movement of proteins inside cells, making protein processing and sorting less efficient.
Treatment
What does that mean for your treatment
No TMEM87A-specific treatment or management approach is currently established in clinical guidelines for people with a pathogenic or loss-of-function variant in the TMEM87A gene.
Gene function
What if the gene works
The TMEM87A gene helps cells manage the flow of proteins through their membrane system. Its protein sits in cellular membranes involved in sorting and transport, which supports steady cell upkeep. Seeing how the TMEM87A gene works makes it easier to understand how cells place key proteins in the right location at the right time.
The TMEM87A gene helps cells guide selected proteins through internal membranes on their way to the cell surface or other compartments. This keeps cellular delivery organized and supports normal cell upkeep.
Its protein supports the sorting of membrane cargo, meaning proteins that need to be packaged and sent to a specific destination. This helps cells keep the right proteins in the right place.
By helping with protein movement, its protein supports the makeup of the cell surface, where cells sense and respond to their surroundings. This contributes to steady communication between the cell and its environment.
What is a variant?
A genetic variant is a minor change in a gene’s DNA sequence. 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 variants do not have any noticeable effect and are part of natural genetic variation. Sometimes, though, a variant changes gene function more significantly and can contribute to or cause a genetic condition.
Genetic variants
What if the gene does not work
Variants in the TMEM87A gene can change the shape, stability, or cell membrane placement of the TMEM87A protein, which may weaken how it interacts with other cell parts. Understanding how TMEM87A gene variants affect protein stability helps explain why milder changes may leave some activity intact, while more disruptive variants can sharply reduce protein production or cause the protein to be broken down early. These differences can lead to a range of cellular effects rather than one uniform outcome.
How variants are linked to conditions
Current evidence does not yet show a broadly confirmed link between the TMEM87A gene and a specific health condition, although research on TMEM87A gene variants and health conditions is still developing. Anyone with a diagnosis involving the TMEM87A gene should rely on guidance from their doctor or genetic counselor rather than general information.
A variant is not necessarily a diagnosis
Gene variants are a normal feature of human biology and are common across the general population. Most have no direct impact on health and simply reflect natural human diversity. For many genes, carrying a variant associated with a condition points to a possible link rather than a definite diagnosis, especially when multiple genes and environmental factors are involved. 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 isn't yet broadly confirmed evidence on specific factors that increase or reduce health risk related to the TMEM87A gene. If TMEM87A is part of your test results, a doctor or genetic counselor can help put it in the context of your personal and family history.
Inheritance of TMEM87A variants
There is not yet a broadly confirmed disease-specific inheritance pattern for the TMEM87A gene, so how TMEM87A gene variants are inherited in relation to health conditions is still being worked out. The TMEM87A gene is located on an autosome, which means a person normally inherits one copy from each parent.
What does my TMEM87A result mean for my family?
There isn’t yet a broadly confirmed inheritance pattern tied to a specific condition for TMEM87A, though this understanding can change as research develops. If you have a specific TMEM87A 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
Genetic testing for TMEM87A variants usually uses a blood sample or saliva sample to read the DNA code in the TMEM87A gene and compare it with the usual sequence. TMEM87A genetic testing may be done as part of a multigene panel, exome sequencing, or genome sequencing, and the report describes any variants that are found.
When should I consider getting a genetic test?
There is not yet a broadly established TMEM87A-specific reason for genetic testing in routine care. Testing decisions are usually based on personal symptoms, medical history, and family history, together with a doctor or genetic counselor.
A genetic result is only one part of your health story
Genetic findings can be informative, but how much they reveal varies with the condition and the kind of variant involved. Factors such as age, lifestyle, environment, and medical history also affect how the body functions over time. For some conditions, especially those shaped by many genes, genetic information offers context rather than certainty and is most useful when considered alongside other parts of care. In other situations, a genetic finding 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 breaks down a drug, moves it through the body, or responds to it at its target. This helps explain why the same medication may work well for one person, work less well for another, or cause more side effects in someone else. These differences are common and are one part of why treatment response can vary from person to person.
What is Pharmacogenetics?
Pharmacogenetics looks at how differences in genes can shape a person’s response to medications. It examines gene and drug relationships to help explain why the same treatment may work differently from one person to another. For many medicines, genes can affect how strongly a drug works or how the body processes it. This information can help support more informed, more individualized treatment decisions.

Drugs influenced by the TMEM87A gene
When should I seek medical advice?
There is not yet a broadly confirmed role for this gene in guiding medication choices. If you have side effects, a medicine is not working as expected, or you have other health concerns, discuss them with your doctor.
