The EMG1 gene gives cells the instructions they need to build ribosomes, the tiny structures that make proteins. This gene helps your body support early growth and brain development by keeping that protein production process working smoothly. If both copies of the EMG1 gene do not work properly, cells cannot make proteins as they should, which can cause Bowen-Conradi syndrome, a rare condition linked to severe growth problems, feeding difficulties, and developmental delay.
What is a gene?
A gene is a piece of DNA that carries instructions your cells use to make molecules or regulate activities in the body. Some genes provide the directions for producing proteins, which do much of the work inside cells. Others mainly help control when certain processes happen, where they take place, and how active they are. Together, genes affect how the body develops and works, and they can influence how you respond to food, stress, or medications.

Overview
EMG1Gene function
What if the gene works
The EMG1 gene helps cells build ribosomes, the structures that make proteins. It is especially important for processing the RNA used to form the small ribosome subunit, which supports normal growth and development.
Risk
What if the gene does not work
Changes that reduce the EMG1 gene's function can cause Bowen-Conradi syndrome, with poor growth, feeding problems, small head size, and developmental delay. Milder or more severe variants may affect when features begin and how strongly they appear.
Treatment
What does that mean for your treatment
No treatment or drug choice approach specific to pathogenic variants in the EMG1 gene is currently established in clinical guidelines. Research on the EMG1 gene mostly focuses on ribosome biology and rare developmental conditions, not on routine treatment guiding use.
Conditions associated with EMG1
Gene function
What if the gene works
Your cells depend on the EMG1 gene for a basic housekeeping job: making ribosomes, the tiny structures that build proteins. Its work happens mainly in the nucleolus, a small area inside the cell where ribosome parts are prepared. This steady behind-the-scenes activity helps everyday protein production stay on track.
The EMG1 gene helps your cells assemble the small unit of ribosomes. These cell structures read genetic instructions and make the proteins your body uses every day.
Inside the nucleolus, the EMG1 gene helps process 18S ribosomal RNA, a main working piece of the small ribosome. It also adds a small chemical mark that helps this piece mature in the proper form.
By helping small ribosomes mature, the EMG1 gene supports steady protein production across the body. Understanding how the EMG1 gene helps build ribosomes makes it easier to see why this basic cell job matters every day.
What is a variant?
A genetic variant is a minor change in the DNA sequence within a gene. These changes are common and are part of normal human diversity, including differences in appearance, metabolism, and the way the body responds to environmental influences. Many do not have any noticeable effect and simply represent natural genetic variation. Sometimes, though, a variant changes how a gene works more substantially and may contribute to or lead to a genetic condition.
Genetic variants
What if the gene does not work
Variants in the EMG1 gene can alter the protein’s shape, make it less stable, or leave too little of it in the nucleolus, the part of the cell where ribosomes are put together. This means EMG1 gene variants and protein function are closely linked, because early 18S rRNA processing and small ribosome assembly may work less efficiently. Some changes have a milder, partial effect, while more severe variants can cause a larger loss of protein stability or proper cell location. In EMG1-related disease, greater functional loss often matches earlier and more pronounced features.
How variants are linked to conditions
Pathogenic variants in both copies of the EMG1 gene cause Bowen-Conradi syndrome, a rare inherited condition with very poor growth before and after birth, feeding difficulties, a small head size, and marked developmental problems. This well-established link between the EMG1 gene and Bowen-Conradi syndrome has been reported most often in Hutterite families because of a shared inherited variant.
A variant is not necessarily a diagnosis
Genetic variants are a normal feature of human biology and are widespread in the general population. Most do not have a direct effect on health and are simply part of natural human diversity. For many genes, carrying a variant associated with a condition suggests a possible link rather than a definite diagnosis, especially when several genes and environmental factors also contribute. In some cases, though, a single well-characterized variant in a specific gene can be enough to confirm a diagnosis.
Are there things that can increase or change my risk?
For EMG1, risk is mainly shaped by the variants inherited from both parents rather than by lifestyle or environmental factors. There is not broadly confirmed evidence that diet, exercise, or other day-to-day factors change the chance of an EMG1-related condition.
Inheritance of EMG1 variants
EMG1-related Bowen-Conradi syndrome follows an autosomal recessive inheritance pattern. This means a child usually needs to inherit two disease-causing variants in the EMG1 gene, one from each parent, to have the condition. Parents who each carry one variant are usually unaffected carriers, and with each pregnancy they have a 25% chance of having an affected child, a 50% chance of having a child who is also a carrier, and a 25% chance of having a child who inherits neither variant. This is the established pattern for how EMG1 variants are inherited in this condition.
What does my EMG1 result mean for my family?
For EMG1, the main established family pattern is recessive. This usually means parents of an affected child are healthy carriers, and brothers or sisters may also be carriers or, less often, also have the condition. Other close relatives can sometimes carry the same gene change, so the result may matter for family planning across the wider family as well.
Genetic information
Genetic testing
How you find out about variants
To look for changes in the EMG1 gene, genetic testing usually uses a blood or saliva sample and reads the DNA sequence. Genetic testing for EMG1 variants can show whether a person carries a disease causing variant, but results are interpreted alongside symptoms and family history.
When should I consider getting a genetic test?
Testing the EMG1 gene may be worth considering if a baby or child has signs of Bowen-Conradi syndrome, such as very poor growth before and after birth, a very small head, and major feeding problems. It can also be important if this condition runs in the family or both parents are known carriers, especially when planning a pregnancy.
A genetic result is only one part of your health story
A genetic finding can provide valuable insight, but what it reveals depends on the condition and the type of variant involved. Lifestyle, environment, age, and medical history are among the many factors that influence how the body functions over time. For some conditions, especially those shaped by many genes, genetic information provides context rather than certainty and is most useful when considered together with other parts of care. In other situations, a genetic result can give a clear answer. In areas such as 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. 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 how differences in a person’s genes can affect their response to medicines. By looking at links between genes and drugs, it helps explain why the same treatment may work differently from one person to another. For many medications, genes can influence how strongly a drug works or how the body handles it. Understanding this can support treatment decisions that are more informed and more individualized.

Drugs influenced by the EMG1 gene
When should I seek medical advice?
There is not yet a broadly confirmed role for this gene in predicting how medicines will work. For questions about side effects, unusual reactions, or whether a treatment fits your health needs, talk with your doctor.
