TMEM260 helps the body during early development, especially as the heart, brain, and other organs are forming before birth. This gene plays an important role in how cells build and organize tissues at that stage. If the TMEM260 gene does not work properly, a child may be born with a heart difference and can also have developmental delay, growth problems, or changes affecting the brain or kidneys. Effects vary from person to person, depending on the specific variant.
What is a gene?
Genes are sections of DNA that hold information your cells use to make molecules or regulate activities in the body. Some genes provide the directions for producing proteins, the parts of cells that carry out much of the work. Other genes mainly control when certain processes happen, where they take place, and how active they are. Together, genes affect how the body grows and works, and they can also influence how you respond to food, stress, and medications. For a closer look at this topic, you can learn more in the LearnHub.
Overview
TMEM260Gene function
What if the gene works
The TMEM260 gene helps support early body development, especially heart formation. Its protein is found in cell membranes and appears important for growth before birth.
Risk
What if the gene does not work
More disruptive variants in the TMEM260 gene can cause a rare condition with congenital heart problems, often alongside kidney or urinary tract differences. Some children also have developmental delay, and effects can range from milder to severe.
Treatment
What does that mean for your treatment
No TMEM260-specific treatment or management approach is currently established. Care is guided by the person’s actual medical findings, such as structural differences that may need standard supportive or surgical care, rather than by a drug choice linked specifically to the TMEM260 gene.
Gene function
What if the gene works
The TMEM260 gene helps your body make a membrane protein, which means the protein sits within the thin layers that surround cells. This placement lets cells organize important signals during growth. TMEM260 is especially active in early development, when the heart, brain, and other organs are first taking shape.
TMEM260 makes a protein that sits in a cell membrane rather than floating freely inside the cell. That position helps the cell keep signals linked to growth organized.
TMEM260 is active while organs are forming in the embryo. This support is especially important for normal heart development before birth and for the early nervous system.
What is a variant?
A genetic variant is a minor change in a gene’s DNA sequence. These changes are common and are part of normal human diversity, including differences in appearance, metabolism, and the way the body reacts to environmental influences. Many variants do not have any noticeable effect and are simply part of natural genetic variation. At times, though, a variant changes how a gene works more significantly and may contribute to or cause a genetic condition.
Genetic variants
What if the gene does not work
Variants in the TMEM260 gene often lower how much TMEM260 protein a cell can make or leave the protein too unstable to work normally. In TMEM260 gene variants linked to congenital heart and kidney differences, more disruptive changes can result in little or no working protein, while milder variants may leave some activity. This range in functional effect can influence how early features appear and how extensive they are.
How variants are linked to conditions
Pathogenic variants in the TMEM260 gene can cause a rare inherited condition called structural heart defects and renal anomalies syndrome. People with this condition are born with heart differences and may also have kidney changes, growth or feeding problems, and developmental delay. In this setting, TMEM260 gene variants linked to congenital heart defects and kidney problems can confirm the diagnosis when both copies of the gene are affected.
A variant is not necessarily a diagnosis
DNA variants are a usual part of human biology and are widespread in the general population. Most do not have a direct effect on health and instead reflect natural human variation. For many genes, having a variant associated with a condition indicates 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 the 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 TMEM260 gene. In families with a disease-causing TMEM260 change, risk is mainly shaped by whether that change is inherited, and a doctor or genetic counselor can help explain personal and family risk.
Inheritance of TMEM260 variants
TMEM260-related conditions are inherited in an autosomal recessive pattern. This means a child usually inherits one TMEM260 variant from each parent, and the parents are often healthy carriers. When both parents carry a variant in the TMEM260 gene, each pregnancy has a 25% chance of being affected, a 50% chance of resulting in a carrier child, and a 25% chance of inheriting neither variant. This TMEM260 gene inheritance pattern affects boys and girls equally.
What does my TMEM260 result mean for my family?
Changes in TMEM260 linked to a known condition are usually passed down in a recessive pattern. For family members, this often means parents may be healthy carriers, and brothers or sisters could also be affected or be carriers. Close relatives may want to learn whether the same TMEM260 change runs in the family, especially if there is a history of heart, kidney, or developmental problems.
Genetic information
Genetic testing
How you find out about variants
To find out whether you carry a change in the TMEM260 gene, doctors use TMEM260 genetic testing on a blood sample or cheek swab. A lab reads the gene's DNA code and checks for variants, then classifies each finding as linked to a genetic condition, likely harmless, or uncertain based on established evidence.
When should I consider getting a genetic test?
TMEM260 testing may be considered if a baby or child has a serious heart difference present at birth, especially when it occurs with developmental delays or differences in the brain, kidneys, or face. It can also help when there is a known TMEM260 variant in the family or more than one affected child.
A genetic result is only one part of your health story
A genetic finding may offer useful insight, but what it can tell you depends on the condition and the kind of variant involved. Other factors, including lifestyle, environment, age, and medical history, also shape how the body functions over time. In 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 give a clear answer. In areas like medication response, genetic results can help put individual experiences into perspective.
Pharmacogenetics
How variants shape your response to medicine
Genetic variation can affect how people respond to medicines. Some people break down a drug more quickly or more slowly, while others may be more or less sensitive to the same treatment. This is one reason a medication may work well for one person, have little effect in another, or cause more side effects in someone else.
What is Pharmacogenetics?
Pharmacogenetics examines how genetic differences can shape a person’s response to medications. It looks at relationships between genes and drugs to help explain why the same treatment can work differently from one person to another. For many medications, genes influence both how strongly a drug works and how the body handles it. This information can support more informed and more individualized treatment decisions.

Drugs influenced by the TMEM260 gene
When should I seek medical advice?
There is not yet a broadly confirmed role for this gene in how medicines work, so medication side effects, new symptoms, or questions about treatment are best discussed with your doctor.
