The TMEM167A gene helps cells sort and move materials between their internal compartments, especially near the Golgi apparatus, the cell’s packaging center. The protein made by this gene helps your cells keep normal membrane traffic running smoothly. If the gene does not work well, cells may handle proteins and other materials less effectively, which can interfere with normal body development and function. Rare variants in the TMEM167A gene have been linked to inherited health conditions, though the effects can vary from person to person.
What is a gene?
Genes are sections of DNA that hold information your cells use to make molecules or to regulate processes in the body. Some genes carry the instructions for producing proteins, the functional parts of cells. Other genes mainly determine when, where, and how strongly particular processes occur. As a group, genes affect how the body develops and works, and they can influence how you respond to food, stress, or medications. For a deeper look at this topic, you can learn more in the LearnHub.
Overview
TMEM167AGene function
What if the gene works
The TMEM167A gene helps cells organize and move small membrane sacs that carry proteins between cell compartments. This supports normal cell trafficking and the work of lysosomes, the cell’s recycling centers.
Risk
What if the gene does not work
Milder to more severe variants in the TMEM167A gene can disrupt how the Golgi and related cell compartments sort and move proteins. This can impair normal membrane trafficking and cell organization to different degrees.
Treatment
What does that mean for your treatment
No TMEM167A-specific treatment or management approach is currently established, so a pathogenic or loss-of-function variant in the TMEM167A gene does not currently guide drug choices in routine care.
Gene function
What if the gene works
Inside cells, the TMEM167A gene supports the movement of materials through the cell’s internal shipping system. Its protein is mainly linked to compartments that package, sort, and send cargo to where it is needed. Understanding how the TMEM167A gene helps cells sort and move proteins makes its day to day role easier to picture.
The TMEM167A gene helps cells sort and direct cargo in small membrane sacs. This supports normal delivery of proteins and other materials.
Its protein supports the Golgi apparatus (the cell’s packaging center), helping this structure stay organized. That helps freshly made proteins move through processing and delivery steps.
This gene helps coordinate traffic between compartments that package, route, and recycle cell materials. This keeps everyday cell transport steady across many cell types.
What is a variant?
A genetic variant is a minor change in a gene’s DNA sequence. These changes are common and are part of 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 simply represent natural genetic variation. In some situations, though, 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 TMEM167A gene can change the protein’s shape, stability, or placement in cell membranes, which may reduce how well it supports intracellular trafficking (movement of materials inside the cell). In discussions of how TMEM167A gene variants affect protein function, severity matters: milder variants may leave some residual activity, while more disruptive changes, including truncating variants, can lead to very little or no functional protein. Some changes may also weaken the protein’s interactions with other cell components.
How variants are linked to conditions
TMEM167A does not yet have a broadly confirmed link to a specific health condition, though research on how TMEM167A gene variants are linked to health conditions is still developing. If you carry a change in the TMEM167A gene, your doctor or genetic counselor can interpret it alongside your symptoms, family history, and the exact variant reported.
A variant is not necessarily a diagnosis
Genetic variants are a usual part of human biology and are widespread in the general population. Most do not have a direct effect on health and simply contribute to normal human diversity. For many genes, carrying a variant associated with a condition suggests 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 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 risks related to the TMEM167A gene. If a change in TMEM167A has been found in you or your family, a doctor or genetic counselor can explain what it may mean for your personal situation.
Inheritance of TMEM167A variants
There is not yet a broadly confirmed disease specific inheritance pattern for the TMEM167A gene, so answers about how TMEM167A gene variants are inherited remain cautious and may change as research develops. TMEM167A is located on an autosome rather than a sex chromosome, so you inherit one copy of the TMEM167A gene from each parent, and inheritance is not expected to differ between sons and daughters.
What does my TMEM167A result mean for my family?
There isn't yet a broadly confirmed inheritance pattern tied to a specific condition for TMEM167A, though this understanding can change as research develops. If you have a specific TMEM167A result and questions about what it could mean for your family, a doctor or genetic counselor can explain it in the context of your relatives and family history.
Genetic information
Genetic testing
How you find out about variants
TMEM167A genetic testing looks for changes in the TMEM167A gene using DNA from a blood sample, saliva, or a cheek swab. A lab reads the gene, often as part of a larger gene panel or exome test, and compares it with a usual reference sequence. Results may show whether you carry a variant linked to a genetic condition.
When should I consider getting a genetic test?
TMEM167A testing is not usually ordered on its own in routine care. Decisions about testing are usually based on the overall pattern of symptoms and family history, often as part of a broader genetic test discussed with a doctor or genetic counselor.
A genetic result is only one part of your health story
Genetic results can provide useful insight, but how much they show depends on the condition and on the kind of variant involved. Over time, many factors, including lifestyle, environment, age, and medical history, also affect how the body functions. For some conditions, especially those shaped by many genes, genetic information offers context instead of certainty and is best understood together with other parts of care. In other situations, a genetic result 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. This happens because the body absorbs, breaks down, transports, or reacts to a drug a little differently from one person to another. These common differences can influence how well a treatment works or how likely someone is to notice side effects.
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 may work differently from one person to another. With many medicines, genes influence both how strongly a drug works and how the body processes it. This information can support more informed, more individualized treatment decisions.

Drugs influenced by the TMEM167A gene
When should I seek medical advice?
There is not yet a broadly confirmed role for this gene in guiding medicine choices or predicting medication response, so any questions about symptoms, side effects, or treatment are best discussed with your doctor.
