The TMEM267 gene helps cells use cilia, the tiny antenna-like structures that guide signaling during growth and organ development. When this gene does not work properly, those signals can be disrupted, which may contribute to inherited conditions caused by cilia not working as they should, sometimes affecting development, vision, and other organs.
What is a gene?
Genes are sections of DNA that provide instructions cells can use to make molecules or regulate processes in the body. Some genes hold the information needed to produce proteins, which are the working parts of cells. Other genes mainly control 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 influence how you respond to food, stress, or medications. For a more in depth look at this topic, you can find additional information in the LearnHub.
Overview
TMEM267Gene function
What if the gene works
The TMEM267 gene helps make a membrane protein in primary cilia, the tiny antennae on many cells. This supports cell signaling involved in normal growth and development.
Risk
What if the gene does not work
Changes in the TMEM267 gene may weaken how cells build or use cilia, tiny cell structures that help sense signals. Milder variants may partly reduce this work, while more severe variants can disrupt it more strongly.
Treatment
What does that mean for your treatment
No TMEM267-specific treatment or management approach is currently established in clinical guidelines.
Gene function
What if the gene works
Many of your cells use tiny antenna-like structures called cilia to sense and respond to signals. The TMEM267 gene helps build and organize these structures, especially where a cilium connects to the rest of the cell. Understanding TMEM267 gene function helps explain how cells keep signaling orderly during everyday growth and maintenance.
TMEM267 helps cells form and maintain primary cilia, which act like tiny antennae. Its protein works near the base of the cilium and supports the organized shape this structure needs for normal activity.
Because many cell signals are handled through cilia, TMEM267 supports how cells receive and pass along these messages. This helps cells coordinate routine growth and normal body patterning in a controlled way.
What is a variant?
A genetic variant is a minor change in the DNA sequence within a gene. These changes are common and help shape normal human diversity, including differences in appearance, metabolism, and the way the body reacts to environmental influences. Many variants do not lead to any noticeable effects and are simply part of natural genetic variation. Sometimes, though, a variant can change how a gene works more significantly and may play a role in, or directly cause, a genetic condition.
Genetic variants
What if the gene does not work
Variants in the TMEM267 gene can alter the protein’s shape, stability, or placement in the cell, especially at the cilium, a small antenna-like structure on many cells. More disruptive changes, such as early stop or frameshift variants, may leave little or no working protein, while some missense variants can leave partial function. In practical terms, how TMEM267 gene variants affect protein activity often comes down to weaker interactions with other cilia proteins and less reliable cilia signaling.
How variants are linked to conditions
Variants in the TMEM267 gene do not yet have a broadly confirmed link to a specific health condition, and the link between TMEM267 gene variants and disease may become clearer as research develops. Anyone with a confirmed TMEM267-related diagnosis should rely on guidance from their doctor or genetic counselor rather than general information.
A variant is not necessarily a diagnosis
Variants in genes are a normal feature of human biology and are common throughout the general population. Most have no direct effect on health and instead reflect natural human diversity. For many genes, carrying a variant associated with a condition suggests a possible association rather than a definitive diagnosis, especially when multiple genes and environmental factors 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 TMEM267 gene. People with questions about what TMEM267 may mean for their own or their family’s health can talk with a doctor or genetic counselor.
Inheritance of TMEM267 variants
TMEM267 gene inheritance is currently understood as autosomal recessive for the condition it has been linked with. This means a person usually inherits one altered copy of the TMEM267 gene from each parent before they are affected. Parents who each carry one variant are typically unaffected carriers, and with each pregnancy there is a 25% chance the child will inherit both altered copies, a 50% chance the child will be a carrier, and a 25% chance the child will inherit neither altered copy. Sons and daughters are affected at similar rates.
What does my TMEM267 result mean for my family?
There is not yet a broadly confirmed inheritance pattern tied to a specific, well-established condition for TMEM267, and this picture may become clearer as research grows. If you have a TMEM267 result and want to understand what it could mean for parents, children, brothers, sisters, or future pregnancies, a doctor or genetic counselor can explain it in the context of your exact finding.
Genetic information
Genetic testing
How you find out about variants
Genetic testing for TMEM267 variants usually uses a blood or saliva sample, which a lab reads to look for changes in the TMEM267 gene. Results may identify a variant linked to a genetic condition, find no relevant variant, or show a variant of uncertain significance, which means the result is not yet clear.
When should I consider getting a genetic test?
There is not yet a broadly established TMEM267-specific reason for genetic testing in routine care. Testing decisions are usually based on your symptoms, family history, and whether a doctor or genetic counselor thinks a broader gene panel may be helpful.
A genetic result is only one part of your health story
How informative a genetic finding is depends on both the condition and the specific kind of variant. Over time, the way the body functions is shaped by many factors, including age, environment, lifestyle, and medical history. For some conditions, particularly those affected by many genes, genetic information provides context rather than certainty and is most useful when considered with other parts of care. In other situations, a genetic result can give a clear answer. In areas like medication response, genetic results may help make sense of an individual’s experiences.
Pharmacogenetics
How variants shape your response to medicine
Genetic variation can affect how people respond to medicines. Small differences in genes can change how the body absorbs, breaks down, transports, or responds to a drug, so the same treatment may work well for one person but less well for another. This is a common part of normal human variation and can influence both how effective a medicine feels and how likely someone is to notice side effects.
What is Pharmacogenetics?
Pharmacogenetics examines the ways genetic differences affect a person’s response to medications. By looking at patterns between genes and drugs, it helps 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 processes it. This information can support treatment decisions that are more informed and more individualized. More detailed information on this topic is available in the LearnHub.
Drugs influenced by the TMEM267 gene
When should I seek medical advice?
There is not yet a broadly confirmed role for this gene in how people respond to medicines, so routine treatment decisions are not based on it. If you have side effects, trouble with a treatment, or questions about your health or medicines, speak with your doctor.
