The RPL15 gene helps make a ribosome protein, which is part of the cell’s protein-making machinery. Every cell in your body uses this gene to build proteins needed for growth, repair, and normal day to day function. If the gene does not work properly, cells may struggle to make enough proteins, and blood-forming cells can be affected most. Pathogenic variants in the RPL15 gene are linked to a rare inherited anemia called Diamond-Blackfan anemia, which can cause low red blood cells, tiredness, and sometimes growth or birth differences.
What is a gene?
A gene is a piece of DNA that carries instructions your cells use to make molecules or guide processes in the body. Some genes provide the instructions for building proteins, which are the parts of cells that do much of the work. Other genes mainly help regulate when certain processes happen, where they happen, and how active they are. Taken together, genes affect how the body grows and works, and they can influence how you respond to food, stress, or medications. For a more detailed explanation of this topic, you can find more in the LearnHub.
Overview
RPL15Gene function
What if the gene works
The RPL15 gene helps build the large part of ribosomes, the cell structures that make proteins. By supporting protein production, it helps cells grow, maintain tissues, and carry out everyday functions.
Risk
What if the gene does not work
Variants in the RPL15 gene can cause Diamond-Blackfan anemia, with low red blood cell production, often from infancy. Milder and more severe variants may change when it starts and whether growth or birth differences are also present.
Treatment
What does that mean for your treatment
No treatment or management approach tailored to the RPL15 gene is currently established in clinical guidelines. The RPL15 gene is being studied in early cancer research as a possible biomarker and drug target, but this has not changed routine care.
Conditions associated with RPL15
Gene function
What if the gene works
Your cells need a steady supply of proteins for repair, growth, and everyday work. The RPL15 gene helps build the large part of the ribosome, the cell structure that makes proteins. This helps explain how the RPL15 gene supports protein production throughout the body.
The RPL15 gene helps assemble the large section of the ribosome. It works with a type of RNA that forms part of this protein-making structure, so cells can build ribosomes correctly.
As part of the finished ribosome, its protein helps cells follow RNA instructions and link amino acids into proteins. Those proteins are then used for growth, repair, and routine cell maintenance.
What is a variant?
A genetic variant is a small change in the DNA sequence within a gene. These changes are common and help create normal human diversity, including differences in appearance, metabolism, and how the body responds to environmental influences. Many variants do not have any noticeable effect and simply represent natural genetic variation. In some situations, however, 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
Variants in the RPL15 gene can change the shape or amount of the RPL15 protein, making it harder for cells to assemble ribosomes, the structures that build proteins. Some variants only partly reduce this process, while more severe variants can sharply disrupt ribosome formation or lead to loss of the protein altogether. This is how variants in the RPL15 gene affect ribosome assembly and protein production inside cells.
How variants are linked to conditions
The RPL15 gene does not yet have a broadly confirmed link to a specific health condition, though this may change as research develops. For people looking into RPL15 gene variants and related conditions, individual findings are best interpreted with a doctor or genetic counselor rather than general information alone.
A variant is not necessarily a diagnosis
Genetic variants are common across the general population and are a normal part of human biology. Most do not directly affect health and simply reflect natural human diversity. For many genes, having a variant associated with a condition points to a possible link rather than a certain diagnosis, particularly when more than one gene and environmental factors 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 factors that increase or reduce health risk related to the RPL15 gene. If a change in RPL15 has been found in you or your family, a doctor or genetic counselor can help explain what it may mean for your personal risk.
Inheritance of RPL15 variants
For families asking how RPL15 gene variants are inherited, the best-established pattern is autosomal dominant. This means a parent carrying a disease-causing variant in the RPL15 gene can pass it to a child with a 50% chance in each pregnancy. Some people with an RPL15-related condition have a new, de novo variant, which means it was not inherited from either parent. When a parent does not carry the variant in blood testing, the chance for future children is usually much lower, though not always zero.
What does my RPL15 result mean for my family?
Some RPL15 changes are linked to an inherited condition called Diamond-Blackfan anemia, which often follows a dominant pattern in families. This means close relatives, such as a parent, child, brother, or sister, could also carry the same change and may have symptoms ranging from very mild to more noticeable. In some families, the change starts new in one person, so it is not always inherited from a parent.
Genetic information
Genetic testing
How you find out about variants
To look for changes in the RPL15 gene, RPL15 genetic testing uses a blood or saliva sample and reads the DNA code for variants. Results may identify a variant linked to a genetic condition, show no relevant variant, or find a variant of uncertain significance, which means its health effect is not yet clear.
When should I consider getting a genetic test?
Genetic testing for the RPL15 gene may be worth considering if a child has severe anemia starting in infancy, especially when the bone marrow is not making enough red blood cells, with or without birth differences. It can also be helpful when Diamond-Blackfan anemia runs in the family.
A genetic result is only one part of your health story
Genetic findings can offer valuable insight, but how much they reveal depends on the condition and the type of variant involved. Other factors, including lifestyle, environment, age, and medical history, also shape how the body works over time. For some conditions, especially those influenced by many genes, genetic information provides context rather than certainty and is best understood alongside other parts of care. In other situations, a genetic result may give a clear answer. In areas such as 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, so the same treatment may work well for one person but less well for another. Some gene changes influence how the body absorbs, breaks down, or moves a drug, while others can affect how strongly the drug acts on its target. These differences are common and can shape both how much benefit someone gets from a medicine and how sensitive they are to side effects.
What is Pharmacogenetics?
Pharmacogenetics examines how genetic differences shape the way a person responds to medications. It looks at gene and drug patterns to help explain why the same treatment can work differently from one person to another. For many medicines, genes influence both how strongly a drug works and how the body handles it. This information can support more informed, more individualized treatment decisions.

Drugs influenced by the RPL15 gene
When should I seek medical advice?
There is not yet a broadly confirmed role for this gene in guiding medication choices, so questions about side effects, new symptoms, or how well a treatment is working are best discussed with your doctor.
