The TMEM244 gene provides instructions for a protein associated with cell membranes and is thought to influence how some cells communicate and grow. If this gene is not working normally or is unusually active, cell behavior can change, especially in certain immune cells. Researchers have linked abnormal activity of the TMEM244 gene to rare T-cell lymphomas, including Sézary syndrome.
What is a gene?
Genes are sections of DNA that carry instructions your cells use to make molecules or regulate processes throughout the body. Some genes provide the directions for producing proteins, the cell components that do much of the work. Others mainly control when certain processes happen, where they take place, and how active they are. Altogether, genes affect how the body develops and functions, and they can influence how you respond to food, stress, or medications. More detail on this topic is available in the LearnHub.
Overview
TMEM244Gene function
What if the gene works
The TMEM244 gene provides instructions for a protein linked to the cell membrane. It is active in some blood and immune cells and may help with cell signaling.
Risk
What if the gene does not work
Changes in the TMEM244 gene may alter how much TMEM244 protein a cell makes or how the protein is built. Milder and more severe variants can affect the protein’s function to different degrees.
Treatment
What does that mean for your treatment
No TMEM244-specific treatment or management approach is currently established for people with a pathogenic or loss-of-function variant in the TMEM244 gene. TMEM244 is being studied mainly as a possible biomarker in certain T cell blood cancers rather than as a target that currently guides drug choice.
Gene function
What if the gene works
In your cells, the TMEM244 gene is linked to routine activity at the cell surface. Its protein is associated with the cell membrane, where cells receive and pass along information. This helps explain how the TMEM244 gene works in cells during everyday cell communication.
The TMEM244 gene provides instructions for a protein connected with the cell membrane, the layer that surrounds each cell. Proteins in this location help cells respond to signals and stay coordinated with their environment.
What is a variant?
A genetic variant is a minor difference in the DNA sequence within a gene. These differences are common and help shape normal human diversity, such as variation in appearance, metabolism, or the way the body reacts to environmental influences. Many do not cause any noticeable effect and are simply part of natural genetic variation. In some situations, though, a variant changes how a gene works more significantly and can contribute to or cause a genetic condition.
Genetic variants
What if the gene does not work
Variants in the TMEM244 gene can change the TMEM244 protein’s structure, stability, or the amount a cell makes. In TMEM244 gene variant effects on protein stability, milder changes may slightly alter folding or membrane placement, while more severe variants can disrupt how the gene’s message is assembled, create an early stop signal, or leave little to no usable protein. These differences can produce a range from partial loss of function to near-complete loss.
How variants are linked to conditions
Variants in the TMEM244 gene do not yet have a broadly confirmed link to a specific health condition, though research on TMEM244 gene variants linked to conditions is still developing. If you have a confirmed TMEM244 finding, your doctor or genetic counselor can explain what it may or may not mean for you.
A variant is not necessarily a diagnosis
Variants in genes 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 simply contribute to natural 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 play a role. In some situations, though, a single well-characterized variant in a particular 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 risk related to the TMEM244 gene. If TMEM244 is part of your test results, a doctor or genetic counselor can help put it in context with your personal and family history.
Inheritance of TMEM244 variants
There is not yet a broadly confirmed, disease-associated Mendelian inheritance pattern for the TMEM244 gene, so the TMEM244 inheritance pattern is not defined in the same way as for genes linked to a clearly established inherited condition. As research develops, this understanding may become more specific. The TMEM244 gene is located on an autosome rather than a sex chromosome, which means each person inherits one copy from each parent.
What does my TMEM244 result mean for my family?
There is not yet a broadly confirmed inheritance pattern tied to a specific health condition for TMEM244, and understanding may change as research develops. If you have a specific TMEM244 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
TMEM244 genetic testing looks for changes in the TMEM244 gene using a blood sample, saliva, or cheek swab. A lab reads the DNA code in this gene and compares it with the usual version to identify variants. TMEM244 genetic testing can show whether a variant is present, but the result still needs clinical interpretation.
When should I consider getting a genetic test?
There is not yet a broadly established, TMEM244-specific reason for genetic testing in routine care. Testing decisions are usually based on your symptoms and family history, with guidance from a doctor or genetic counselor.
A genetic result is only one part of your health story
A genetic finding can provide useful insight, but how much it explains depends on the condition and on the kind of variant identified. Many factors, including lifestyle, environment, age, and medical history, influence how the body functions over time. For some conditions, particularly those shaped by many genes, genetic information offers context rather than certainty and is most meaningful 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 can help make sense of individual experiences.
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 less effect in another, or causes more side effects in someone else. Small differences in genes can change how the body breaks down, moves, or responds to a drug, and this kind of variation is common.
What is Pharmacogenetics?
Pharmacogenetics looks at how genetic differences shape a person’s response to medications. It examines gene and 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 understanding can help support treatment decisions that are more informed and more individualized.

Drugs influenced by the TMEM244 gene
When should I seek medical advice?
There is not yet a broadly confirmed role for this gene in guiding medicine choices or predicting side effects. If you have concerns about a medication, notice new symptoms after starting treatment, or feel that a medicine is not working as expected, speak with your doctor.
