The RPS24 gene helps make ribosomes, the tiny cell machines that build proteins your body needs to grow and stay healthy. When this gene does not work properly, some cells cannot make proteins as well, especially in the bone marrow where blood cells are formed. A harmful variant in the RPS24 gene can cause Diamond-Blackfan anemia, which often leads to low red blood cells, tiredness, pale skin, and sometimes growth or physical differences present from birth. RPS24 is mainly known in medical genetics rather than public culture.
What is a gene?
Genes are pieces 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 the work. Other genes mainly determine when certain processes happen, where they happen, and how strongly they operate. Together, genes affect how the body develops and works, and they can also influence how you respond to food, stress, or medications. More in depth information about this topic is available in the LearnHub.
Overview
RPS24Gene function
What if the gene works
The RPS24 gene helps build the small part of ribosomes, the cell structures that make proteins. This supports normal cell growth, repair, and blood formation.
Risk
What if the gene does not work
Variants in the RPS24 gene can cause Diamond-Blackfan anemia, with reduced red blood cell production that may lead to anemia, tiredness, and sometimes growth differences. Mild and more severe variants can influence when features appear and how marked they are.
Treatment
What does that mean for your treatment
No RPS24-specific treatment or drug choice is currently established for a loss-of-function or other pathogenic variant in the RPS24 gene. Care is based on the person’s diagnosed condition, and the RPS24 gene is mainly being studied within Diamond-Blackfan anemia research rather than as a direct drug target.
Conditions associated with RPS24
Gene function
What if the gene works
Every day, your cells need a steady supply of ribosomes, the tiny structures that build proteins. The RPS24 gene helps make and maintain part of these protein making machines. Understanding how the RPS24 gene helps make ribosomes can make it easier to see how cells keep up with daily protein production.
The RPS24 gene provides a protein that becomes part of the ribosome’s small section, which helps read genetic instructions. This gives cells one of the stable parts they need before proteins can be made.
Inside the nucleolus (the cell area where ribosomes are made), its protein helps shape early ribosomal RNA into 18S rRNA, a core piece of the small ribosome section. This helps new ribosomes mature in an orderly way.
As part of the finished ribosome, RPS24 helps cells turn genetic messages into proteins. This supports everyday needs such as growth, repair, and routine cell upkeep.
What is a variant?
A genetic variant is a slight difference in the DNA sequence of a gene. These changes are common and help shape normal human diversity, including differences in appearance, metabolism, or how the body responds to environmental influences. Many variants do not have any noticeable effect and are simply part of natural genetic variation. In some situations, though, a variant can change how a gene functions more significantly and may contribute to or cause a genetic condition.
Genetic variants
What if the gene does not work
Variants in the RPS24 gene can lower the amount of RPS24 protein made or change its shape, which can disrupt early ribosome assembly inside cells. These RPS24 gene variants range from milder changes that partly reduce protein function to more severe variants that greatly limit production, and this often affects how strongly ribosome building is impaired. In Diamond-Blackfan anemia, stronger loss of function may be linked to earlier or more noticeable features.
How variants are linked to conditions
Pathogenic variants in the RPS24 gene cause Diamond-Blackfan anemia, a rare inherited condition that often appears in infancy with low red blood cell counts. In studies of RPS24 gene variants and Diamond-Blackfan anemia, some people also have short stature or physical differences present from birth, while others have milder findings.
A variant is not necessarily a diagnosis
Variants in genes are a usual part of human biology and are widely seen in the general population. Most do not directly affect health and instead reflect normal 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 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 lifestyle or environmental factors that increase or reduce health risks linked to the RPS24 gene. In most cases, risk is mainly shaped by whether a disease-causing variant is present in the family, and anyone concerned about personal or family risk should speak with a doctor or genetic counselor.
Inheritance of RPS24 variants
RPS24-related conditions are usually inherited in an autosomal dominant pattern. That means a parent carrying a disease-causing variant in the RPS24 gene has a 50% chance of passing it on in each pregnancy, regardless of the child’s sex. In some families, a child has the variant for the first time because of a new (de novo) change, so it was not inherited from either parent. When people look up how RPS24 variants are inherited, this dominant pattern is the main one linked to RPS24-related Diamond-Blackfan anemia.
What does my RPS24 result mean for my family?
Changes in the RPS24 gene are linked to a form of Diamond-Blackfan anemia that usually runs in families in a dominant pattern, so close relatives such as parents, brothers, sisters, and children may also carry the same change. This can matter even when symptoms are mild or have never been recognized in the family. Some cases happen as a new gene change in one person, so a parent does not always have it.
Genetic information
Genetic testing
How you find out about variants
To find out about variants in the RPS24 gene, doctors use genetic testing on a blood or saliva sample. Genetic testing for RPS24 gene variants reads the DNA code to look for changes and may be done on its own or as part of a larger gene panel. Results show whether a variant was found and how it is classified.
When should I consider getting a genetic test?
Testing for the RPS24 gene may be considered if someone has Diamond-Blackfan anemia, especially severe anemia that starts in infancy, or if this condition runs in the family. It can also help explain low red blood cell production along with birth differences or growth problems.
A genetic result is only one part of your health story
A genetic result can be informative, but how much it reveals depends on the condition and the specific variant involved. How the body functions over time is also shaped by many influences, including lifestyle, environment, age, and medical history. In some conditions, especially those affected by many genes, genetic information offers context rather than certainty and is best considered together with other parts of care. In other situations, a genetic result may give a clear answer. In areas like medication response, genetic results can also help put personal experiences into context.
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 but less well for another, or why some people are more sensitive to side effects. Small differences in genes can change how the body breaks down a drug, moves it through the body, or responds to it at its target. These differences are common and can influence both how well a medicine works and how strongly it affects you.
What is Pharmacogenetics?
Pharmacogenetics examines how genetic differences can affect a person’s response to medication. It looks at connections between genes and drugs to help explain why the same treatment may work differently from one person to another. For many medicines, genes can influence both how strongly a drug works and how the body handles it. This information can support treatment decisions that are more informed and more individualized.

Drugs influenced by the RPS24 gene
When should I seek medical advice?
There is not yet a broadly confirmed role for this gene in guiding how medicines work, so it is a good idea to speak with your doctor or pharmacist if you have concerns about side effects, treatment changes, or how a medication is working for you.
History
In recent decades, awareness of this gene’s role has grown. The RPS24 gene entered medical genetics in the 2000s, when researchers studying Diamond-Blackfan anemia identified variants in this gene in some affected families. This was an important step because it showed that the condition could be linked to genes involved in the cell’s protein-making machinery, not just to one single cause. Building on this early work, scientists recognized RPS24 as part of a broader group of ribosomal protein genes tied to inherited bone marrow failure. Since then, its history has mainly been shaped by efforts to refine genetic diagnosis and to better understand why people with the same condition can have different features.
