The MRPS24 gene helps mitochondria, the parts of cells that make energy, build some of the proteins they need to work properly. This gene plays an important role in keeping energy production steady, especially in the brain and muscles. If both copies of the MRPS24 gene do not work properly, a person can develop a rare mitochondrial condition that may lead to poor growth, delayed development, low muscle tone, and other problems linked to low cellular energy.
What is a gene?
Genes are stretches of DNA that carry instructions cells use to make molecules or regulate what happens in the body. Some provide the information needed to produce proteins, the parts of cells that do much of the work. Others mainly direct when certain processes occur, where they happen, and how active they are. Together, genes affect how the body develops and functions, and they can influence how you respond to food, stress, or medications. You can find more about this topic in the LearnHub.
Overview
MRPS24Gene function
What if the gene works
The MRPS24 gene helps make part of the mitochondrial ribosome, a cell structure that builds proteins inside mitochondria. This supports energy production, especially in tissues with high energy needs.
Risk
What if the gene does not work
Variants in the MRPS24 gene can reduce mitochondrial energy production and cause developmental delay, poor growth, and neurologic features including low muscle tone or seizures. Effects may range from milder to more severe and can begin at different ages.
Treatment
What does that mean for your treatment
For a pathogenic or loss-of-function variant in the MRPS24 gene, no gene-specific treatment or drug-choice approach is currently established in clinical guidelines.
Gene function
What if the gene works
Inside your cells, the MRPS24 gene helps mitochondria build a small but essential part of their protein building machinery. This lets mitochondria produce some of the proteins they need for everyday energy production. In simple terms, this is part of how the MRPS24 gene helps mitochondria make energy for the body.
The protein made from the MRPS24 gene becomes part of the mitochondrial ribosome, the structure that builds proteins inside mitochondria. It helps form the small working part of that machine, which is needed to start and guide this process.
This protein helps the mitochondrial ribosome handle genetic instructions carried by mitochondrial RNA (a working copy of genetic information). That support helps the cell place protein building blocks in the right order.
Proteins made with help from the MRPS24 gene are used in the system that turns food and oxygen into usable cell energy. This supports steady energy supply in tissues that work hard every day, such as muscles and the brain.
What is a variant?
A genetic variant is a small difference in the DNA sequence of a gene. These differences are common and help shape normal human diversity, such as variation in appearance, metabolism, or how the body responds to environmental influences. Many have no noticeable effect and simply represent natural genetic variation. In some cases, though, a variant can change how a gene works more substantially and may contribute to or cause a genetic condition.
Genetic variants
What if the gene does not work
Changes in the MRPS24 gene can make its protein unstable, keep it from joining the mitochondrial ribosome, or shorten it so it cannot work. This is how MRPS24 gene variants affect mitochondrial protein synthesis: cells make fewer proteins needed for normal energy production. Milder variants may leave some activity, while more severe variants can cause a bigger drop in this protein making process.
How variants are linked to conditions
The MRPS24 gene does not yet have a broadly confirmed link to a specific health condition, although this can change as research develops. Information about MRPS24 gene variants and disease is still emerging, so anyone with a confirmed MRPS24-related finding should rely on guidance from their doctor or genetic counselor for personal interpretation.
A variant is not necessarily a diagnosis
Gene variants are a usual part of human biology and are widely found in the general population. Most have no direct impact on health and simply represent natural human diversity. For many genes, carrying a variant connected with a condition suggests a possible association rather than a definite diagnosis, especially when more than one gene and environmental factors are involved. In some situations, though, a single well characterized variant in a particular gene can be enough to confirm a diagnosis.
Are there things that can increase or change my risk?
There is no broadly confirmed evidence that lifestyle or environmental factors change the chance of having an MRPS24-related condition. Risk is mainly linked to whether disease-causing changes in MRPS24 are inherited from both parents, so family history is the main factor that can affect the chance in a pregnancy.
Inheritance of MRPS24 variants
The way MRPS24 gene variants are inherited in the known related condition is autosomal recessive. This means a child usually inherits one altered copy of the MRPS24 gene from each parent. Parents who carry one altered copy are typically called carriers. When both parents are carriers, each pregnancy has a 25% chance of an affected child, a 50% chance of a child who is a carrier, and a 25% chance of a child who inherits two working copies.
What does my MRPS24 result mean for my family?
Changes in the MRPS24 gene are linked to a rare inherited condition that usually runs in families in a recessive pattern. For family members, this often means parents can be healthy carriers, and brothers or sisters may also be affected or be carriers. Close relatives may want to learn whether the same gene change is present in the family.
Genetic information
Genetic testing
How you find out about variants
To find out whether you carry a variant in the MRPS24 gene, doctors use genetic testing for MRPS24 variants, usually on a blood or saliva sample. A lab reads the DNA code and compares it with the usual sequence to look for changes, often through a broader gene panel or exome test rather than a single gene test.
When should I consider getting a genetic test?
Testing for MRPS24 may be considered when a baby or child has signs of a rare inherited condition that affects the body's energy-making system, such as developmental delay, low muscle tone, seizures, or poor growth. It can also be relevant if a close family member has an MRPS24-related condition or a known MRPS24 gene change.
A genetic result is only one part of your health story
Genetic results can provide useful insight, but how much they reveal depends on the condition and on the specific type of variant. Many factors, including lifestyle, environment, age, and medical history, also shape how the body works over time. For some conditions, especially those influenced by many genes, genetic information provides context rather than certainty and is best considered 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 make sense of individual experiences.
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 its effects at the target tissue. This helps explain why the same medication may work well for one person, work less well for another, or cause more side effects in someone who is more sensitive to it.
What is Pharmacogenetics?
Pharmacogenetics examines how genetic differences can affect a person’s response to medicines. By looking at links between genes and medications, it helps explain why the same treatment may work differently from one person to another. For many drugs, genes can influence both how strongly a medicine works and how the body processes it. This information can support treatment decisions that are more informed and more individualized. More detail on this topic is available in the LearnHub.
Drugs influenced by the MRPS24 gene
When should I seek medical advice?
There is not yet a broadly confirmed role for changes in this gene in guiding medication choices, so any concerns about medicines, side effects, or your health are best discussed with your doctor.
