The RNF113B gene appears to help cells process RNA, the working copy of genetic instructions that cells use to make proteins. If this gene does not work normally, that message handling step may be less accurate, which can affect how some proteins are made. This gene is not one of the more publicly recognized genes, and it has not become a common focus in everyday health discussions.
What is a gene?
Genes are stretches of DNA that give your cells instructions to make molecules or to regulate processes in the body. Some genes carry the directions for producing proteins, the parts of cells that do the work. Other genes mainly control when certain processes happen, where they take place, and how strongly they run. Together, genes affect how the body develops and works, and they can influence how you respond to food, stress, or medications.

Overview
RNF113BGene function
What if the gene works
The RNF113B gene is thought to help cells process RNA, the working copy of genetic instructions. This can support normal protein production and everyday cell function.
Risk
What if the gene does not work
Changes in the RNF113B gene can reduce or alter the RNF113B protein made in cells. Milder variants may leave some function, while more severe variants can greatly reduce protein activity or stop the protein from being made.
Treatment
What does that mean for your treatment
No RNF113B-specific treatment or management approach is currently established in clinical guidelines.
Gene function
What if the gene works
RNF113B supports the normal flow of genetic information inside cells. Its role centers on RNA, the temporary message copied from DNA before a protein is made. This gives a clear picture of how the RNF113B gene helps cells use genetic instructions each day.
The RNF113B gene is involved in preparing RNA messages so cells can use DNA instructions in an orderly way. This supports normal protein production during everyday cell activity.
What is a variant?
Genetic variants are small differences in the DNA sequence of a gene. They are common and help shape normal human diversity, including differences in appearance, metabolism, and the way the body responds to environmental influences. Many have no noticeable effect at all and simply represent natural genetic variation. Sometimes, 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 RNF113B gene can change the protein sequence or reduce how much of the protein a cell makes. Milder variants may leave some protein activity or stability intact, while more disruptive variants can create a shortened protein, impair its interactions, or stop production altogether. In practice, how RNF113B gene variants affect function depends on whether the change subtly alters the protein or causes partial or near complete loss of function.
How variants are linked to conditions
Current evidence on RNF113B gene variants and health conditions is still limited. RNF113B does not yet have a broadly confirmed link to a specific health condition, though this may change as research develops. If you have a reported variant in the RNF113B gene, your clinician or genetic counselor can place it in the context of your personal and family history.
A variant is not necessarily a diagnosis
Genetic variants are common across the general population and are a normal feature 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 several genes and environmental influences play a role. In some situations, though, one 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 RNF113B gene. People who have questions about their personal or family risk can talk with a doctor or a genetic counselor.
Inheritance of RNF113B variants
There is not yet a broadly confirmed disease specific inheritance pattern for the RNF113B gene, so a single answer to how RNF113B gene variants are inherited has not been established. As research develops, this picture may become clearer. RNF113B is located on an autosome, which means each person inherits one copy from each parent.
What does my RNF113B result mean for my family?
There is not yet a broadly confirmed inheritance pattern tied to a specific health condition for RNF113B, and this can change as research develops. If you have a specific RNF113B result and want to understand what it could mean for relatives, a doctor or genetic counselor can help explain it in the context of your family history.
Genetic information
Genetic testing
How you find out about variants
To look for changes in the RNF113B gene, RNF113B genetic testing uses a blood or saliva sample. A laboratory reads the gene’s DNA code and compares it with a reference sequence, then reports whether a variant was found and how clearly its health meaning is understood.
When should I consider getting a genetic test?
There is not yet a broadly established RNF113B-specific reason for genetic testing in routine care. Decisions about testing are usually based on your symptoms, health history, and family history, and are best made with a doctor or genetic counselor.
A genetic result is only one part of your health story
Genetic results can offer useful insight, but how much they reveal depends on the condition and the type of variant involved. Many factors, including lifestyle, environment, age, and medical history, influence how the body works over time. For some conditions, especially those affected 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 can give a clear answer. In areas like medication response, genetic results can also help place individual experiences in 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 may work well for one person, have less effect in another, or cause more side effects in someone who is more sensitive to it.
What is Pharmacogenetics?
Pharmacogenetics examines the ways genetic differences can affect how a person responds to medications. By studying connections between genes and drugs, it helps clarify why the same treatment may work differently from one person to another. For many medicines, genes can influence both how strong a drug’s effects are and how the body processes it. This information can support treatment decisions that are more informed and more individualized. More on this topic is available in the LearnHub.
Drugs influenced by the RNF113B gene
When should I seek medical advice?
There is not yet a broadly confirmed role for this gene in guiding medicine choices, so concerns about side effects, new symptoms, or how a treatment is working are best discussed with your doctor.
