The RPL23 gene helps build part of the ribosome, the cell’s protein making machinery. When a harmful variant reduces its function, cells may struggle to make proteins normally, especially in the bone marrow, which can lead to low red blood cell production, tiredness, and sometimes growth or developmental differences. This gene plays an important role in everyday cell function, but it has not gained broad public attention.
What is a gene?
A gene is a stretch of DNA that carries instructions your cells use to make molecules or regulate processes in the body. Some genes provide the directions for making proteins, the parts of cells that do much of the work. Other genes mostly help control when certain processes happen, where they happen, and how strongly they occur. Taken together, genes affect how the body develops and functions, and they can influence how you respond to food, stress, or medications.

Overview
RPL23Gene function
What if the gene works
The RPL23 gene helps make a protein that forms part of the ribosome, the cell’s protein-making machinery. This supports everyday cell growth, repair, and maintenance.
Risk
What if the gene does not work
Milder to more severe variants in the RPL23 gene can impair assembly of the large ribosome subunit, reducing protein production and sometimes triggering cell stress signals.
Treatment
What does that mean for your treatment
No treatment or drug choice approach is currently established specifically for pathogenic variants in the RPL23 gene.
Gene function
What if the gene works
Your cells need the RPL23 gene to keep protein production moving. It helps build part of the ribosome, the cell's machine for making proteins, so cells can turn genetic instructions into working proteins. Understanding what the RPL23 gene does in the body helps explain how cells grow, repair, and carry out everyday tasks.
The RPL23 gene helps form the large half of the ribosome, the cell's machine for making proteins. This supports a stable structure for steady protein production.
As part of the ribosome, its protein helps cells read RNA, a working copy of genetic instructions, and link protein building blocks together. Those finished proteins support growth, repair, and everyday cell work.
What is a variant?
A genetic variant is a minor change in the DNA sequence of a gene. These changes are common and contribute to the normal differences seen among people, such as 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 cases, though, a variant changes 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 RPL23 gene can alter the shape or amount of the RPL23 protein, making it harder for cells to build a stable ribosome and keep protein production moving normally. This is how RPL23 gene variants affect ribosome function: milder variants may partly reduce assembly or stability, while more severe variants can strongly disrupt ribosomal RNA binding, ribosome formation, and trigger cellular stress signals.
How variants are linked to conditions
Research on how variants in the RPL23 gene are linked to conditions is still developing, and this gene does not yet have a broadly confirmed connection to one specific health condition. That picture may change as larger studies and clinical reports build over time. Anyone with a confirmed RPL23-related diagnosis should use advice from their doctor or genetic counselor to understand what it means for them.
A variant is not necessarily a diagnosis
Genetic variants are a routine part of human biology and are widespread in the general population. Most do not have a direct effect on health and simply reflect natural human variation. For many genes, having 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, one well understood 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 RPL23 gene. If a change in RPL23 has been found in you or your family, a doctor or genetic counselor can explain what that result may mean for your personal risk.
Inheritance of RPL23 variants
For families asking how RPL23 gene variants are inherited, the best established pattern is autosomal dominant. This means a person with a disease-causing variant in the RPL23 gene can pass it to a child with a 50% chance in each pregnancy, regardless of the child’s sex. Some people with an RPL23 gene variant are the first in their family to have it because it arose as a new, de novo variant rather than being inherited from either parent.
What does my RPL23 result mean for my family?
For people with a disease-causing change in the RPL23 gene, the family pattern is usually dominant, which means close relatives such as parents, brothers, sisters, and children may also carry the same change. Some relatives can have clear signs, while others may have milder findings or no obvious symptoms. Some cases happen for the first time in one person, so a parent does not always have the same gene change.
Genetic information
Genetic testing
How you find out about variants
Genetic testing for RPL23 variants usually uses a blood or saliva sample, and a lab reads the DNA sequence to look for changes in the RPL23 gene. It may be done as part of a panel, exome, or genome test, and results can show whether a variant is present, absent, or of uncertain significance.
When should I consider getting a genetic test?
There is not yet a broadly established, RPL23-specific reason for genetic testing in routine care. Testing decisions are usually made with a doctor or genetic counselor based on your symptoms, medical history, and family history, often as part of a broader gene panel rather than for RPL23 alone.
A genetic result is only one part of your health story
A genetic result can provide useful insight, but what it reveals varies with the condition and the kind of variant involved. Lifestyle, environment, age, and medical history, among other factors, also influence how the body functions over time. For some conditions, especially those shaped by many genes, genetic information offers context rather than certainty and is most useful when considered along with other parts of care. In other situations, a genetic result can give a clear answer. In areas like medication response, genetic results can also help put individual experiences into context.
Pharmacogenetics
How variants shape your response to medicine
Genetic variation can affect how people respond to medicines. Small differences in DNA can change how the body breaks down a drug, moves it through the body, or responds to it at its target. This helps explain why the same treatment may work well for one person, seem less effective for another, or cause more side effects in someone else.
What is Pharmacogenetics?
Pharmacogenetics examines how differences in a person’s genes can affect their response to medicines. It studies gene and drug patterns to better understand why the same treatment can work differently from one person to another. For many medications, genes help shape how the body processes a drug or how strongly it affects the body. This information can support more informed and more personalized treatment decisions. More on this topic is available in the LearnHub.
Drugs influenced by the RPL23 gene
When should I seek medical advice?
There is not yet a broadly confirmed role for this gene in guiding medication choice or dose. For questions about side effects, how well a treatment is working, or possible drug interactions, talk with your doctor.
History
RPL23 entered the medical literature through broader efforts to identify the human genes that encode ribosomal proteins, a major focus of cell biology in the late 20th century. Early work linked it to the long-standing effort to map the parts of the ribosome, the cell structure that makes proteins. From these first observations, research expanded steadily as scientists cloned the gene, placed it on a chromosome, and compared it with related genes in other species. That work helped show how strongly conserved many ribosomal protein genes are across evolution. Unlike a few genes that became widely known through public health stories, RPL23 has remained mainly part of laboratory and genetics research.
