The RPS23 gene gives your cells instructions for part of the ribosome, the cell’s protein making machinery. The protein made by this gene helps your cells read genetic instructions accurately, so if it does not work properly, protein production can become less precise and growth and development may be affected. People with harmful variants in the RPS23 gene may have developmental delay, learning differences, hearing loss, or short stature.
What is a gene?
Genes are sections of DNA that carry instructions your cells use to make molecules or manage processes throughout the body. Some genes provide the directions for producing proteins, which do much of the work inside cells. Others mainly regulate when certain processes happen, where they happen, and how active they are. Taken together, genes affect how your body develops and functions, and they can influence how you respond to food, stress, or medications. For a deeper look at this topic, you can find more in the LearnHub.
Overview
RPS23Gene function
What if the gene works
The RPS23 gene helps form part of the ribosome, your cells’ protein making machinery. This lets cells read genetic instructions accurately and make proteins needed for growth, repair, and everyday function.
Risk
What if the gene does not work
Variants in the RPS23 gene can cause a ribosome related condition with developmental delay, learning difficulties, and hearing loss. Effects can range from milder delays to earlier, broader problems with growth and brain development.
Treatment
What does that mean for your treatment
No treatment or drug choice is currently guided specifically by a pathogenic variant in the RPS23 gene. The RPS23 gene is being studied in broader research on ribosome function, cell growth, and cancer, but this has not yet changed routine treatment.
Gene function
What if the gene works
Every day, your cells need a steady supply of proteins to grow, repair, and carry out routine work. The RPS23 gene supports this by helping build and run ribosomes, the cell structures that read genetic instructions and assemble proteins. Understanding what the RPS23 gene does in the body helps explain how cells keep protein production accurate and reliable.
The RPS23 gene provides one of the proteins used to build the small half of the ribosome. This helps your cells keep their protein-making machinery stable and ready for routine work.
Its protein sits in the part of the ribosome that reads messenger RNA (a working copy of genetic instructions). This helps the cell follow the code in the right order as it makes a protein.
RPS23 supports accurate matching between each RNA code and the next amino acid building block. This helps proteins be assembled in the correct sequence for normal cell activity.
What is a variant?
A genetic variant is a minor difference in the DNA sequence within a gene. These differences are common and help explain normal variation among people, such as differences in appearance, metabolism, or the way the body reacts to environmental influences. Many variants do not cause any noticeable effect and are simply part of natural genetic variation. In some situations, though, a variant can change how a gene works more significantly and may contribute to or lead to a genetic condition.
Genetic variants
What if the gene does not work
Changes in the RPS23 gene can affect ribosome function by changing the shape or stability of a protein that helps cells read genetic instructions accurately. Milder variants may leave some activity in place, while more severe variants can sharply reduce how well the protein is made or how well it fits into the ribosome. As a result, RPS23 gene variants often lower the accuracy or efficiency of protein building inside cells.
How variants are linked to conditions
The RPS23 gene does not yet have a broadly confirmed link to a specific health condition, though research on possible RPS23 gene variants and health conditions is still developing. Anyone with a confirmed RPS23-related diagnosis should rely on guidance from their doctor or genetic counselor rather than general information.
A variant is not necessarily a diagnosis
Genetic variants are a normal feature of human biology and are common throughout the general population. Most do not have a direct effect on health and simply represent natural human diversity. For many genes, carrying a variant associated with a condition points to a possible link rather than a definite diagnosis, especially when more than one gene and environmental factors are involved. In some instances, though, a single well-characterized variant in a specific gene is enough to confirm the diagnosis.
Are there things that can increase or change my risk?
There isn't yet broadly confirmed evidence on specific factors that increase or reduce risk related to the RPS23 gene. If a change in RPS23 is found, personal risk usually depends more on the specific genetic change and family history than on lifestyle or environmental factors.
Inheritance of RPS23 variants
There is not yet a broadly confirmed, single disease inheritance pattern for the RPS23 gene that applies across all reported findings, so how RPS23 gene variants are inherited is still being clarified. RPS23 is located on chromosome 5, which is an autosome, so you inherit one copy of the RPS23 gene from each parent. In general, that means variants in this gene can be passed through either side of the family.
What does my RPS23 result mean for my family?
There is not yet a broadly confirmed inheritance pattern tied to a specific condition for RPS23, and this area is still being worked out. If you have a specific RPS23 result and want to understand what it could mean for your relatives, a doctor or genetic counselor can help explain it in the context of your family.
Genetic information
Genetic testing
How you find out about variants
Testing for variants in the RPS23 gene usually uses a blood or saliva sample. If you are looking into how genetic testing for RPS23 variants works, a lab reads the gene’s DNA code and checks for changes linked to a genetic condition. Results may show a known variant, no variant, or a change whose meaning is still being clarified.
When should I consider getting a genetic test?
There is not yet a broadly established, RPS23-specific reason for most people to have genetic testing. Testing is usually considered as part of a wider genetics evaluation based on symptoms or a personal or family history reviewed with a doctor or genetic counselor.
A genetic result is only one part of your health story
A genetic result can be quite informative, but how much it explains varies by the condition and the specific variant involved. Lifestyle, environment, age, and medical history are among the many factors that influence how the body functions over time. In some conditions, especially those affected by many genes, genetic information provides context rather than certainty and is most useful when viewed alongside other parts of care. In other situations, a genetic result may offer 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 genes 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 medication works well for one person, has less effect in another, or causes more side effects in someone else. These differences are common and can influence both how well a treatment works and how sensitive a person may be to it.
What is Pharmacogenetics?
Pharmacogenetics examines how genetic differences affect the way a person responds to medications. It studies patterns 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 how strongly a drug works or how the body handles it. This information can support more informed, individualized treatment decisions.

Drugs influenced by the RPS23 gene
When should I seek medical advice?
There is not yet a broadly confirmed role for this gene in guiding medication response, so general questions about medicines, side effects, or changes in how you feel are best discussed with your doctor.
