The TMEM223 gene helps make a protein that is part of cell membranes, the thin barriers that help cells control what comes in and out. This gene plays an important role in normal cell activity at the membrane. If it does not work as it should, these membrane processes may be disrupted, which can change how some cells function.
What is a gene?
Genes are sections of DNA that carry instructions your cells use to make molecules or regulate processes in the body. Some genes provide the directions for producing 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 operate. Together, genes affect how the body develops and functions, and they can influence how you respond to food, stress, or medications.

Overview
TMEM223Gene function
What if the gene works
The TMEM223 gene gives cells instructions for making a membrane protein. This protein likely helps support normal cell structure and routine cell activity.
Risk
What if the gene does not work
Variants in the TMEM223 gene can change how much TMEM223 protein cells make or how well it works in cell membranes. Milder variants may leave some activity, while more severe variants can greatly reduce or eliminate normal protein function.
Treatment
What does that mean for your treatment
No treatment or drug choice is currently guided by pathogenic variants in the TMEM223 gene.
Gene function
What if the gene works
In many cells, the TMEM223 gene supports normal mitochondrial activity. Mitochondria are the parts of cells that make most of your usable energy. This helps explain how the TMEM223 gene supports mitochondrial energy production in everyday cell function.
The TMEM223 gene helps cells maintain steady energy production through normal mitochondrial function. This supports routine cell work such as movement, signaling, and basic upkeep.
The TMEM223 gene makes a small protein that becomes part of the mitochondrial membrane, where energy making steps take place. Its position helps these processes run in an organized 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, or how the body responds to environmental influences. Many variants have no noticeable effect and simply represent 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
Changes in the TMEM223 gene can affect protein function by altering the protein's shape, stability, or placement within the cell. Some variants are mild and may leave part of the protein working, while more severe variants can shorten the protein or stop it from being made. This severity range can change how strongly the cell-level effects appear.
How variants are linked to conditions
Variants in the TMEM223 gene do not yet have a broadly confirmed link to a specific health condition, although research on TMEM223 gene variants and health conditions is still developing. If you carry a confirmed variant in the TMEM223 gene, your doctor or genetic counselor can help interpret it in the context of your personal and family history.
A variant is not necessarily a diagnosis
Genetic variants are common across the general population and are a normal feature of human biology. Most do not directly affect health and instead reflect natural human diversity. For many genes, having a variant associated with a condition suggests a possible link rather than a certain diagnosis, especially when several genes and environmental factors play a role. In some cases, 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 is not yet broadly confirmed evidence on specific factors that increase or reduce health risk related to the TMEM223 gene. If a TMEM223 change is found on genetic testing, a doctor or genetic counselor can help explain what it may mean for your personal and family risk.
Inheritance of TMEM223 variants
There is not yet a broadly confirmed inheritance pattern for TMEM223 gene variants tied to a specific TMEM223-related condition. As research stands, the inheritance of TMEM223 gene variants is not defined in the same clear way as genes known to cause autosomal dominant, autosomal recessive, or X-linked conditions. The TMEM223 gene is located on an autosome, which means you inherit one copy from your mother and one copy from your father.
What does my TMEM223 result mean for my family?
There is not yet a broadly confirmed inheritance pattern tied to a specific health condition for TMEM223, and this picture may become clearer as research grows. If you have a TMEM223 result, what it means for relatives depends on the exact change found and why testing was done.
Genetic information
Genetic testing
How you find out about variants
TMEM223 genetic testing looks for variants in the TMEM223 gene using a blood sample, saliva sample, or cheek swab. A laboratory reads the DNA in that gene and reports whether a variant was found, which can help clarify an inherited finding in you or your family.
When should I consider getting a genetic test?
There is not yet a broadly established TMEM223-specific reason for genetic testing in routine care. Decisions about testing are usually based on your personal health and family history, and are best made with a doctor or genetic counselor.
A genetic result is only one part of your health story
Genetic test findings can be informative, but how much they reveal varies by the condition and the specific type of variant. Over time, how the body works is also shaped by factors such as lifestyle, environment, age, and medical history. For some conditions, especially those influenced by many genes, genetic information provides context rather than certainty and is best considered alongside 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 individual experiences into perspective.
Pharmacogenetics
How variants shape your response to medicine
Genetic variation can affect how people respond to medicines. This helps explain why the same treatment works well for one person, has little effect in another, or causes more side effects in someone else. Part of the difference comes from how each body breaks down, moves, and responds to a drug. These inherited differences are common and can influence both how well a medicine works and how sensitive a person may be to it.
What is Pharmacogenetics?
Pharmacogenetics examines how genetic differences can shape the way a person responds to medication. It studies gene-drug patterns to help explain why the same treatment may work differently from one person to another. For many medicines, genes affect either how strongly a drug works or how the body processes it. This information can support treatment decisions that are more informed and more individualized.

Drugs influenced by the TMEM223 gene
When should I seek medical advice?
There is not yet a broadly confirmed role for this gene in how medicines work, so questions about side effects, new symptoms, or whether a treatment is right for you are best discussed with your doctor.
