The METTL24 gene gives your cells instructions for a protein in the methyltransferase-like family, which helps control how other proteins work by adding small chemical marks. This gene plays an important role in keeping cell activity balanced, especially in how cells signal and respond to their environment. If the METTL24 gene does not work properly, those control signals may be disrupted and normal cell function can be affected. Any health effects from variants in this gene can vary from person to person.
What is a gene?
Genes are sections of DNA that give your cells instructions to make molecules or regulate processes in the body. Some genes provide the directions for producing proteins, which are the parts of cells that do much of the work. Others mainly control when certain processes happen, where they happen, and how active they are. Together, genes affect how the body develops and functions, and they can also shape how you respond to food, stress, and medications. For a more detailed explanation of this topic, you can find additional information in the LearnHub.
Overview
METTL24Gene function
What if the gene works
The METTL24 gene helps make a protein that may add small chemical tags inside cells. These tags can help control everyday cell activity.
Risk
What if the gene does not work
Changes in the METTL24 gene may reduce or alter how much METTL24 protein a cell makes or how well it works. Milder variants may leave some activity, while more severe variants can cause a greater loss of normal protein function.
Treatment
What does that mean for your treatment
At present, no METTL24-specific treatment or management approach is established for people with a pathogenic or loss-of-function variant in the METTL24 gene.
Gene function
What if the gene works
Inside your cells, the METTL24 gene supports a basic form of chemical control. It is part of a group of genes that make methyltransferase-like proteins, which add small methyl tags to molecules to adjust their activity. This gives a simple picture of METTL24 gene function in normal cells.
The METTL24 gene makes a protein with features of a methyltransferase, an enzyme that transfers small methyl tags. Cells use this kind of chemical tagging to fine tune how other molecules behave during normal activity.
What is a variant?
A genetic variant is a small difference in the DNA sequence of a gene. These changes are common and help create normal human diversity, including differences in appearance, metabolism, or how the body responds to environmental influences. Many variants do not cause any noticeable effect and simply represent natural genetic variation. In some situations, though, a variant can change the function of a gene more substantially and may contribute to or cause a genetic condition.
Genetic variants
What if the gene does not work
Variants in the METTL24 gene can change how the cell builds or processes the protein, which helps explain how METTL24 gene variants affect protein function. Some changes may slightly alter the protein’s shape or stability, while more disruptive variants can interfere with RNA splicing (how the cell edits the gene message) or lead to little or no protein being made. This creates a spectrum, with milder variants partly reducing activity and more severe variants causing a larger functional loss.
How variants are linked to conditions
The METTL24 gene does not yet have a broadly confirmed link to a specific health condition, though this can change as research develops. Current evidence on METTL24 gene variants and health conditions is still emerging, so people with a confirmed variant should use their doctor’s or genetic counselor’s advice for personal interpretation.
A variant is not necessarily a diagnosis
Genetic variants are a routine feature of human biology and are widely found in the general population. Most do not directly affect health and simply reflect natural differences among people. For many genes, carrying a variant connected with a condition points to a possible link rather than a certain diagnosis, especially when several genes and environmental influences play a part. In some situations, though, one well studied variant in a particular gene is enough to confirm a 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 health risk related to the METTL24 gene. Anyone with concerns about their personal or family risk can talk with a doctor or genetic counselor.
Inheritance of METTL24 variants
There is not yet a broadly confirmed inheritance pattern tied to a specific condition for the METTL24 gene, so METTL24 gene inheritance is not described with one established dominant, recessive, or X-linked pattern. The METTL24 gene is located on chromosome 17, which is an autosome. That means you inherit one copy of the METTL24 gene from each parent, as with most genes on the numbered chromosomes.
What does my METTL24 result mean for my family?
There is not yet a broadly confirmed inheritance pattern tied to a specific health condition for METTL24, and this picture may become clearer as research grows. If you have a specific METTL24 result and want to understand what it could mean for relatives, a doctor or genetic counselor can explain it in the context of your family history.
Genetic information
Genetic testing
How you find out about variants
Genetic testing for METTL24 variants uses DNA from a blood or saliva sample. A lab reads the METTL24 gene to look for spelling changes, often through a multigene panel or exome test. Your results report whether a variant was found and whether it is currently understood to have clinical meaning.
When should I consider getting a genetic test?
There is not yet a broadly established, METTL24-specific medical reason for genetic testing. Decisions about testing are usually based on your personal health history and family history, with guidance from a doctor or genetic counselor.
A genetic result is only one part of your health story
A genetic finding can provide useful information, but how much it explains varies by the condition and the type of variant involved. Lifestyle, environment, age, and medical history are among the many factors that affect how the body works over time. For some conditions, especially those influenced by many genes, genetic information offers context rather than certainty and is best considered alongside other parts of care. In other situations, a genetic result may give a clear answer. In areas such as 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 a person’s DNA 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, do less for another, or cause more side effects in someone else.
What is Pharmacogenetics?
Pharmacogenetics examines how genetic differences can affect a person’s response to medication. It looks for links between genes and drugs to help explain why the same treatment can work differently from one person to another. With many medicines, genes influence either how strongly a drug works or how the body processes it. This understanding can support more informed and more individualized treatment decisions.

Drugs influenced by the METTL24 gene
When should I seek medical advice?
There is no broadly confirmed evidence that changes in this gene should guide medicine choice or dosing, so general questions about side effects, new symptoms, or how your medicines fit your overall health are best discussed with your doctor.
History
METTL24 is a more recently studied gene in human genetics, and its history has taken shape through modern sequencing and gene-mapping research rather than a single widely known medical milestone. As medical science evolved, so did understanding of this gene. Researchers recognized METTL24 as part of a larger family of genes with related naming and structural features, which helped place it within a broader area of genetic study. Early work focused on identifying the gene and describing where it is active in the body. More recent research has continued to refine how scientists classify and study METTL24, reflecting the gradual way many less widely known genes have entered medical genetics.
