The RBM28 gene helps cells build ribosomes, the tiny structures that make the proteins your body needs every day. This gene plays an important role in early growth because steady protein production supports the brain, hair follicles, and hormone making tissues. If you carry a pathogenic variant in the RBM28 gene, cells may struggle to make proteins efficiently, which can lead to a rare condition with hair loss, developmental delay, and endocrine problems such as growth issues or delayed puberty.
What is a gene?
Genes are stretches of DNA that carry instructions your cells use to make molecules or regulate activities in the body. Some genes hold the code for proteins, which are the parts of cells that do much of the work. Others mainly guide when certain processes happen, where they take place, and how strongly they are turned on. As a group, genes influence how the body develops and functions, and they can also affect how you respond to food, stress, or medications. To go into this topic in more detail, you can find more in the LearnHub.
Overview
RBM28Gene function
What if the gene works
Your cells use the RBM28 gene to help build ribosomes, the tiny structures that make proteins. This supports normal growth and steady cell activity, especially in tissues that need frequent renewal.
Risk
What if the gene does not work
Variants in the RBM28 gene can cause a rare condition marked by hair loss, delayed development, and hormone related problems. Milder to more severe variants may affect when features appear, how strong they are, and whether growth is also affected.
Treatment
What does that mean for your treatment
No RBM28-specific treatment or management approach is currently established for people with a pathogenic or loss-of-function variant in the RBM28 gene. Care is symptom-based and tailored to the person’s needs rather than guided by the RBM28 gene itself.
Conditions associated with RBM28
Gene function
What if the gene works
Inside many cells, the RBM28 gene helps keep protein making on track by supporting ribosome production. Ribosomes are the tiny structures that read genetic instructions and build proteins. A central part of RBM28 gene function is guiding early steps in ribosome assembly inside the nucleolus, a busy area within the cell nucleus.
The RBM28 gene helps cells build the larger half of the ribosome. It works in the nucleolus, where ribosomes begin to form from RNA and proteins.
This gene supports processing of ribosomal RNA, the core material inside a ribosome. It helps longer starter RNA molecules be cut and shaped into the mature pieces cells need.
RBM28 also helps bring ribosomal RNA and proteins together during ribosome assembly. This step helps the new ribosome become ready for normal protein production.
What is a variant?
A genetic variant is a minor change in the DNA sequence of a gene. These changes are common and help shape 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 are simply part of natural genetic variation. Sometimes, though, a variant can more clearly change how a gene functions and may contribute to or cause a genetic condition.
Genetic variants
What if the gene does not work
How RBM28 gene variants affect ribosome assembly depends on the change. Some variants shorten or destabilize the protein, so cells cannot process the RNA needed for ribosomes or build these protein making structures efficiently. Milder variants may leave some activity, while more severe loss-of-function variants can cause a larger drop in this process and are linked to earlier or more noticeable features in the RBM28-related condition.
How variants are linked to conditions
Pathogenic variants in both copies of the RBM28 gene cause ANE syndrome, a rare inherited condition historically named alopecia, neurological defects, and endocrinopathy syndrome. In reports on RBM28 gene variants linked to ANE syndrome, people with this diagnosis often have sparse hair or hair loss, developmental delay or intellectual disability, and hormone related findings such as delayed puberty, with features varying from person to person.
A variant is not necessarily a diagnosis
Genetic variants are a routine part of human biology and are widely present in the general population. Most of these variants do not have a direct effect on health and instead represent natural human diversity. For many genes, carrying a variant associated with a condition suggests a possible link rather than a certain diagnosis, especially when several genes and environmental factors also contribute. In some situations, however, a single 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 risk related to the RBM28 gene. For many living with RBM28 changes, risk depends mainly on the exact gene change inherited in the family, and a doctor or genetic counselor can help explain personal risk.
Inheritance of RBM28 variants
RBM28-related conditions are inherited in an autosomal recessive pattern. This means a person usually develops the condition only when they inherit two disease-causing variants in the RBM28 gene, one from each parent. Parents who each carry one RBM28 gene variant are usually unaffected carriers, and with each pregnancy there is a 25% chance of having an affected child, a 50% chance of having a child who is a carrier, and a 25% chance of having a child with no familial variant. In practical terms, RBM28 gene variant inheritance can affect sons and daughters equally.
What does my RBM28 result mean for my family?
For RBM28, the main known family pattern is recessive. This usually means parents of an affected child are healthy carriers, and brothers or sisters may also be affected or may be carriers. Other relatives on both sides of the family may also carry the variant, so the result can matter beyond one person.
Genetic information
Genetic testing
How you find out about variants
To find out whether you carry a variant in the RBM28 gene, doctors use genetic testing for RBM28 variants on a blood or saliva sample. The lab reads the DNA sequence and looks for changes, often through a multigene panel or broader exome or genome testing.
When should I consider getting a genetic test?
Genetic testing for the RBM28 gene may be worth considering when a child has a rare pattern of very sparse or absent hair, slow development, and hormone-related problems, or when this condition runs in the family. It can also help relatives learn whether they carry the same gene change after an RBM28-related condition has been found in the family.
A genetic result is only one part of your health story
A genetic result can provide valuable insight, but what it reveals depends on the condition and the kind of variant involved. Lifestyle, environment, age, and medical history, among other factors, also shape how the body functions over time. For some conditions, particularly those influenced by many genes, genetic information offers context rather than certainty and is best understood 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 help put individual experiences into context.
Pharmacogenetics
How variants shape your response to medicine
Genetic variation can affect how people respond to medicines. A treatment that works well for one person may work less well for another, or may cause more side effects, because the body can absorb, break down, transport, or respond to a drug differently. These differences are common and are one reason medication response is not the same for everyone. In some cases, genetic results can help explain why a person is more sensitive to a medicine or why a treatment may not work as expected.
What is Pharmacogenetics?
Pharmacogenetics examines the ways genetic variation can affect how someone responds to a medication. By studying links between genes and drugs, it helps explain why the same treatment may not work in the same way for every person. With many medicines, genes can influence how powerfully a drug works or how the body handles it. This information can support treatment decisions that are better informed and more individualized.

Drugs influenced by the RBM28 gene
When should I seek medical advice?
There is not yet a broadly confirmed role for this gene in guiding medicine choice or dose, so any concerns about your health, symptoms, or how a medication is affecting you are best discussed with your doctor.
