The TMEM174 gene makes a membrane protein involved in cell signaling pathways linked to growth and survival. The protein made by this gene helps your cells manage internal signals in a more controlled way. If the gene does not work normally, these signals may become less balanced, which can affect how cells grow and function. TMEM174 is mainly discussed in research settings rather than in public health conversations.
What is a gene?
A gene is a stretch of DNA that holds information cells can use to make molecules or to regulate processes in the body. Some genes carry the instructions for producing proteins, the working parts of cells. Others mainly help decide when certain processes happen, where they happen, and how strongly they occur. Taken together, genes affect how the body develops and functions, and they can influence how you respond to food, stress, or medications. You can find more detailed information on this topic in the LearnHub.
Overview
TMEM174Gene function
What if the gene works
The TMEM174 gene provides instructions for a protein that sits in cell membranes and appears to help with cell signaling. It is active in several tissues, including the kidneys and liver.
Risk
What if the gene does not work
Changes in the TMEM174 gene may alter how its membrane protein supports cell signaling, especially pathways linked to cell growth and survival. Milder variants may have little effect, while more severe variants can reduce or disrupt this signaling more clearly.
Treatment
What does that mean for your treatment
A pathogenic or loss-of-function variant in the TMEM174 gene does not currently change treatment or drug choices through any established clinical guideline. The TMEM174 gene is being studied in early cancer research as a possible marker of cell growth and cell signaling, but this has not yet led to a gene-specific treatment approach.
Gene function
What if the gene works
Your cells use the TMEM174 gene to place a small protein on internal membranes, where cell messages are organized and relayed. Understanding TMEM174 gene function helps explain how cells coordinate everyday activity and steady growth.
The TMEM174 gene makes a small protein that sits in cell membranes, mainly on membranes inside the cell. This placement helps cells pass along signals in an organized way.
TMEM174 is linked to signaling pathways that help guide routine cell activity and growth. When these signals are balanced, cells can respond to everyday cues in a coordinated way.
What is a variant?
A genetic variant is a minor 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 the way the body responds to environmental influences. Many variants do not have any noticeable effect and simply reflect natural genetic variation. In some cases, 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 TMEM174 gene may change the shape or stability of its membrane protein, which can affect how much reaches the cell surface and how it interacts with nearby signaling proteins. This pattern helps explain how TMEM174 gene variants affect protein function: milder changes may only partly reduce activity, while more severe variants can create a shortened or unstable protein that cells break down more quickly.
How variants are linked to conditions
At this time, the TMEM174 gene does not have a broadly confirmed link to a specific health condition, and research on TMEM174 gene variants and health conditions is still developing. If you have a reported variant in the TMEM174 gene, your doctor or genetic counselor can explain what that result means in the context of your personal and family health history.
A variant is not necessarily a diagnosis
Genetic variants are a usual part of human biology and are widely found across the population. Most do not directly affect health and simply reflect normal human diversity. For many genes, carrying a variant associated with a condition suggests a possible link rather than a definite diagnosis, especially when several genes and environmental factors also contribute. In some situations, though, a single well characterized variant in a particular 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 TMEM174 gene. Anyone with concerns about personal or family risk can talk with a doctor or genetic counselor.
Inheritance of TMEM174 variants
For families trying to understand how TMEM174 gene variants are inherited, there is not yet a broadly confirmed Mendelian inheritance pattern tied to a specific TMEM174-related condition. As research develops, this picture may become clearer. The TMEM174 gene is located on chromosome 5, which is an autosome, so a person inherits one copy from each parent.
What does my TMEM174 result mean for my family?
There is not yet a broadly confirmed inheritance pattern tied to a specific health condition for TMEM174, though this can change as research develops. If you have a TMEM174 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 finding.
Genetic information
Genetic testing
How you find out about variants
Variants in the TMEM174 gene are found with TMEM174 genetic testing, which reads the DNA sequence from a blood or saliva sample. This may be done with a single gene test, a multigene panel, or broader sequencing such as exome or genome testing.
When should I consider getting a genetic test?
At this point, there is not a widely established medical reason to get genetic testing just for the TMEM174 gene. Testing decisions are usually based on your own health history, symptoms, and family history, and are best discussed with a doctor or genetic counselor.
A genetic result is only one part of your health story
A genetic result can provide useful insight, but how much it reveals varies by the condition and the type of variant involved. Over time, many factors, including lifestyle, environment, age, and medical history, also influence how the body works. For some conditions, especially those shaped by many genes, genetic information provides context rather than certainty and is best considered together with other parts of care. In other situations, a genetic result may offer 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. One person may break down a drug more slowly or more quickly than another, which can change how well it works or how sensitive they are to side effects. These differences are common and are one reason the same treatment can feel helpful for one person but less effective or harder to tolerate for someone else.
What is Pharmacogenetics?
Pharmacogenetics is the branch of medicine that examines how genetic differences affect a person’s response to medications. It studies links between genes and drugs to better explain why treatments work differently from one person to another. For many medicines, genes influence how strongly a drug works or how the body handles it. This information can support more informed and more individualized treatment decisions.

Drugs influenced by the TMEM174 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 concerns about side effects, a medicine not working as expected, or your overall health, discuss them with your doctor.
