The TMEM35B gene gives instructions for a small protein in cell membranes that helps cells handle signals from their surroundings. What this gene does can influence how your body keeps cell communication organized. If the gene is not working well, signaling between cells may be less efficient, which can change how some tissues function. Different TMEM35B variants may affect health in different ways.
What is a gene?
Genes are stretches of DNA that provide cells with instructions to make molecules or regulate processes in the body. Some genes hold the instructions for producing proteins, the parts of cells that do the work. Others mainly help direct when certain processes happen, where they take place, and how strongly they operate. As a group, genes influence how the body develops and functions, and they can also affect how you respond to food, stress, or medications.

Overview
TMEM35BGene function
What if the gene works
The TMEM35B gene gives cells instructions for making a protein linked to cell membranes. It appears to support normal cell signaling and routine cell activity, especially in tissues that rely on steady communication between cells.
Risk
What if the gene does not work
Changes in the TMEM35B gene may reduce how much of its membrane protein is made or how well it works inside cells. Milder variants may leave some activity, while more severe variants can cause greater loss of normal cellular function.
Treatment
What does that mean for your treatment
No TMEM35B-specific treatment or management approach is currently established in clinical guidelines.
Gene function
What if the gene works
Your cells use TMEM35B to make a small protein that sits in a membrane. Understanding how the TMEM35B gene works in the body helps explain how cells carry out routine membrane based tasks. When it is working properly, this supports steady handling of signals and proteins inside the cell.
The TMEM35B gene provides instructions for a small protein that becomes part of a cell membrane. In normal function, this supports steady membrane based activity, including how cells handle proteins and pass along signals.
What is a variant?
A genetic variant is a minor difference in the DNA sequence within a gene. These differences are common and are part of normal human diversity, including variation in appearance, metabolism, and the way the body responds to environmental influences. Many variants do not have any noticeable effect and are simply part of natural genetic variation. Sometimes, though, a variant changes how a gene works more significantly and may contribute to or lead to a genetic condition.
Genetic variants
What if the gene does not work
Variants in the TMEM35B gene can change how much protein a cell makes or how well that protein is folded, placed in membranes, and able to interact with other cell proteins. Researchers studying how TMEM35B gene variants affect protein function find that milder variants may partly reduce activity, while more severe variants can produce a shortened protein or no usable protein at all.
How variants are linked to conditions
Published evidence has not yet established a broadly confirmed link between the TMEM35B gene and a specific health condition. Research on how TMEM35B gene variants are linked to conditions is still developing, so any confirmed finding should be interpreted with your doctor or genetic counselor.
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 have a direct effect on health and instead represent normal human diversity. For many genes, having a variant associated with a condition suggests a possible link rather than a confirmed diagnosis, especially when several genes and environmental factors also play a role. 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 TMEM35B gene. If TMEM35B is part of your test results and you are concerned about what it may mean for you or your family, speaking with a doctor or genetic counselor can help put it in context.
Inheritance of TMEM35B variants
There is not yet a broadly confirmed, disease specific inheritance pattern for the TMEM35B gene, so TMEM35B gene inheritance is not currently described in the same clear way as well established dominant or recessive conditions. TMEM35B is located on an autosome, which means you inherit one copy from each parent.
What does my TMEM35B result mean for my family?
There isn't yet a broadly confirmed inheritance pattern tied to a specific condition for TMEM35B, though this understanding can change as research develops. If you have a specific TMEM35B 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
TMEM35B genetic testing usually uses a blood or saliva sample to read the gene's DNA code and look for variants. This may be done through a multi-gene panel, exome sequencing, or genome sequencing, and the report can show whether a TMEM35B variant was found and how it is classified.
When should I consider getting a genetic test?
There is not yet a broadly established TMEM35B-specific reason for genetic testing in routine care. Decisions about testing are best made with a doctor or genetics specialist, based on your symptoms and family history.
A genetic result is only one part of your health story
A genetic finding can provide useful insight, but how much it reveals depends on the condition and the type of variant involved. Many factors, including lifestyle, environment, age, and medical history, influence how the body works over time. For some conditions, especially those shaped by many genes, genetic information offers context rather than certainty and is best understood alongside other parts of care. In other situations, a genetic result may give a clear answer. In areas such as medication response, genetic results can help place individual experiences in context.
Pharmacogenetics
How variants shape your response to medicine
Genetic variation can affect how people respond to medicines. Two people can take the same treatment at the same dose, yet one may get the expected benefit while another may notice less effect or more side effects. One reason is that inherited differences can change how the body absorbs, breaks down, transports, or responds to a drug, and this kind of variation is common.
What is Pharmacogenetics?
Pharmacogenetics focuses on how genetic differences shape a person’s response to medications. It examines patterns linking genes and drugs to better 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 handles it. This information can support more informed and individualized treatment decisions. You can read more about this topic in the LearnHub.
Drugs influenced by the TMEM35B gene
When should I seek medical advice?
There is not yet a broadly confirmed way to use changes in this gene to guide how medicines are chosen or how well they work. Questions about side effects, new symptoms after starting a medicine, or concerns about how drugs may affect you are best discussed with your doctor or pharmacist.
