The DDX24 gene helps cells handle RNA, a key step in building ribosomes, the cell’s protein-making machinery. If this gene does not work well, cells may struggle to grow and function normally. This gene plays an important role in early tissue development, especially in blood and lymph vessels. Rare pathogenic variants in the DDX24 gene have been linked to vascular malformations, which are unusual clusters or shapes of these vessels that can affect different parts of the body.
What is a gene?
Genes are stretches of DNA that provide cells with instructions to make molecules or manage processes in the body. Some genes hold the information needed to produce proteins, the functional parts of cells. Others mainly regulate when certain processes take place, where they occur, and how active they are. Taken together, genes affect how the body develops and works, and they can influence how you respond to food, stress, or medications.

Overview
DDX24Gene function
What if the gene works
The DDX24 gene helps cells prepare ribosomes, the structures that make proteins. This supports normal growth and regular cell function.
Risk
What if the gene does not work
Variants in the DDX24 gene are linked to venous and lymphatic malformations, with swelling that can range from localized to multiorgan involvement. Different variants can influence how early signs appear and how extensive the vessel changes become.
Treatment
What does that mean for your treatment
No DDX24-specific treatment or drug selection is currently established in clinical guidelines. The DDX24 gene is under study as a possible biomarker and drug target in some cancers, but this has not changed routine care.
Gene function
What if the gene works
Inside many cells, the DDX24 gene supports the careful steps needed to build ribosomes, the structures that make proteins. Its protein works mainly in the nucleolus, where new ribosomes begin to form. Understanding how the DDX24 gene works can make it easier to see how cells keep everyday protein production running smoothly.
The DDX24 gene helps loosen and rearrange RNA, a close chemical cousin of DNA. This uses cell energy so RNA and its partner proteins can take the right positions during ribosome building.
Much of the DDX24 gene’s work happens in the nucleolus, a small area inside the cell nucleus where ribosomes start forming. These steps help prepare ribosomal RNA to become the core structure of a ribosome.
This gene helps bring together RNA and proteins as ribosomes mature. By supporting these assembly steps, it helps cells prepare the machinery needed for everyday protein production.
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, and the way the body responds to environmental influences. Many do not produce any noticeable effect and simply represent natural genetic variation. Sometimes, though, a variant changes how a gene works to a greater extent and may contribute to or lead to a genetic condition.
Genetic variants
What if the gene does not work
In discussions of DDX24 gene variants and function, most disease linked changes seem to alter the RNA helicase protein rather than remove it. Many affect regions needed to bind RNA or ATP (the cell's main energy carrying molecule), which can reduce protein stability, weaken normal interactions, and disturb RNA processing inside cells. Milder variants may leave some activity, while more disruptive variants can interfere more strongly with how cells handle RNA.
How variants are linked to conditions
The main condition linked to variants in the DDX24 gene is multiorgan venous and lymphatic defect syndrome. Pathogenic variants in the DDX24 gene can cause this rare condition, which affects veins and lymph vessels in several parts of the body and may lead to skin or mouth blood vessel spots, swelling, bleeding, or deeper organ involvement. A clearly pathogenic DDX24 variant in this setting can help confirm the diagnosis.
A variant is not necessarily a diagnosis
DNA variants are a routine part of human biology and are widespread in the general population. Most variants do not have a direct effect on health and instead reflect normal human diversity. For many genes, carrying a variant associated with a condition points to a possible link rather than a confirmed diagnosis, especially when several genes and environmental factors also play a role. In other situations, though, a single well-characterized variant in a particular gene can be 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 DDX24 gene. For many living with a DDX24 change, risk appears to depend mainly on the exact gene change itself rather than on clear lifestyle or environmental factors.
Inheritance of DDX24 variants
DDX24-related conditions are inherited in an autosomal dominant pattern. That means a person with a disease-causing variant in the DDX24 gene can pass it to each child, with a 50% chance in every pregnancy, which is the key point in the DDX24 inheritance pattern. Some cases happen because of a new (de novo) variant, so the change is not inherited from either parent. Men and women can both inherit it and pass it on.
What does my DDX24 result mean for my family?
Changes in the DDX24 gene have been linked to a rare condition affecting blood and lymph vessels that is usually passed on in a dominant way, so close relatives such as parents, brothers, sisters, and children may also carry the same gene change. In many families, each child of someone with a disease-causing DDX24 change has a 1 in 2, or 50%, chance of inheriting it. Some cases can happen for the first time in one person, so a parent may not always have the same change.
Genetic information
Genetic testing
How you find out about variants
Genetic testing for DDX24 variants usually uses a blood sample, cheek swab, or saliva sample to read the DNA code in the DDX24 gene. It can look for a specific known variant or sequence the whole gene as part of a larger panel. Results may show a variant, no variant, or a change whose health meaning is still unclear.
When should I consider getting a genetic test?
There isn’t yet a broadly established DDX24-specific reason for genetic testing in routine care. Testing decisions are usually made with a doctor or genetic counselor based on your own health history and any family pattern of related conditions.
A genetic result is only one part of your health story
Genetic results can provide meaningful insight, but how much they reveal varies depending on the condition and the kind of variant involved. Over time, factors such as age, lifestyle, environment, and medical history also shape how the body works. For some conditions, especially those influenced by many genes, genetic information provides context rather than certainty and is best understood as part of the broader picture of care. In other situations, a genetic result may offer a clear answer. In areas like medication response, these results can help put individual experiences into perspective.
Pharmacogenetics
How variants shape your response to medicine
Genetic variation can affect how your body responds to medicines. Some people break down a drug faster or slower than expected, which can change how well it works or how likely side effects are. These differences are common and are one reason the same treatment can feel very effective for one person but less helpful or harder to tolerate for another.
What is Pharmacogenetics?
Pharmacogenetics focuses on how genetic differences shape a person’s response to medication. It studies connections between genes and drugs to help explain why treatments do not work the same way for everyone. With many medicines, genes can affect both how strongly a drug works and how the body handles it. This information can support more informed, individualized treatment decisions.

Drugs influenced by the DDX24 gene
When should I seek medical advice?
There is not yet a broadly confirmed role for this gene in guiding medication response, so if you have concerns about side effects, new symptoms, or how your medicines may be affecting you, the right next step is to speak with your doctor.
