The NAA25 gene helps your cells process newly made proteins so they can work properly. This gene plays an important role in normal cell function, and if it does not work well, protein handling can be disrupted in ways that may affect growth and development. Rare, disease causing variants in the NAA25 gene have been linked to developmental delay and related physical features in some people.
What is a gene?
Genes are stretches of DNA that carry instructions your cells use to make molecules or regulate processes in the body. Some genes provide the directions for producing proteins, the parts of cells that do much of 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 also shape how you respond to food, stress, or medications. For a more detailed look at this topic, you can find more in the LearnHub.
Overview
NAA25Gene function
What if the gene works
The NAA25 gene helps cells place a small chemical tag on many newly made proteins. This tag can affect protein stability, location, and how proteins work.
Risk
What if the gene does not work
Changes in the NAA25 gene can range from milder to more severe variants. They may reduce how well cells place a small chemical tag on some newly made proteins, which can alter protein stability and cell movement.
Treatment
What does that mean for your treatment
No NAA25-specific treatment or management approach is currently established for pathogenic variants in the NAA25 gene.
Gene function
What if the gene works
Inside your cells, the NAA25 gene helps manage an early finishing step for many newly made proteins. It works with partner proteins to place a small acetyl mark on the front end of selected proteins as they are being made. In everyday terms, NAA25 gene function centers on helping cells prepare proteins for steady day to day use.
NAA25 helps selected new proteins receive a small acetyl mark at their starting end. This early finishing step helps set up how those proteins behave inside cells.
This gene provides the helper part of a two protein tagging team with NAA20. It helps the team recognize the right protein targets and carry out the tagging step efficiently.
By supporting this early protein marking step, NAA25 helps proteins interact, settle into place, and stay steady in normal cell life. This supports smooth, routine activity across many tissues.
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 simply represent natural genetic variation. In some situations, though, 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 NAA25 gene can weaken the NAA25 protein, change its shape, or stop the cell from making the full protein. In what happens if the NAA25 gene does not work, milder variants may only partly reduce its link with the partner protein from the NAA20 gene, while more severe variants can lead to protein loss or breakdown. This lowers N-terminal acetylation (a small chemical tag added to many newly made proteins), which can alter protein stability in cells.
How variants are linked to conditions
Variants in the NAA25 gene do not yet have a broadly confirmed link to a specific health condition, so information about NAA25 gene variants and health conditions is still developing. If you have a reported change in the NAA25 gene or a confirmed NAA25-related diagnosis, your doctor or genetic counselor can place that result in the right clinical context.
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 variation among people. In many genes, having a variant associated with a condition points to a possible link rather than a confirmed diagnosis, particularly when several genes and environmental influences play a role. In other situations, though, one well characterized variant in a particular gene may be enough to confirm the 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 NAA25 gene. If a change in NAA25 has been found on testing, a doctor or genetic counselor can help explain what it may mean for personal and family risk.
Inheritance of NAA25 variants
There is not yet a broadly confirmed, disease specific inheritance pattern for NAA25 that is used in routine human genetics, so how NAA25 gene variants are inherited is still being clarified as research develops. The NAA25 gene is located on chromosome 12, which is an autosome. That means a person inherits one copy of the NAA25 gene from each parent.
What does my NAA25 result mean for my family?
There isn't yet a broadly confirmed inheritance pattern tied to a specific condition for NAA25, though this understanding can change as research develops. If you have a specific NAA25 result and questions about what it could mean for your family, a doctor or genetic counselor can help explain it in the context of your personal and family history.
Genetic information
Genetic testing
How you find out about variants
Variants in the NAA25 gene are usually found through genetic testing for NAA25 variants, using a blood sample, saliva, or a cheek swab. A laboratory reads the DNA and compares the gene with the usual sequence, often as part of a multigene panel, exome test, or genome test, then classifies any variant found.
When should I consider getting a genetic test?
There is not yet a broadly established NAA25-specific reason for routine genetic testing. Testing decisions are usually based on your symptoms, personal health history, and family history, and are best discussed with a doctor or genetic counselor.
A genetic result is only one part of your health story
Genetic test results can provide useful insight, but how much they reveal varies with the condition and the kind of variant involved. How the body works over time is also shaped by many other factors, including lifestyle, environment, age, and medical history. For some conditions, especially those influenced by many genes, genetic information offers context rather than certainty and is best understood alongside other parts of care. In other situations, a genetic result may give a clear answer. In areas like medication response, these results can also help put individual experiences into perspective.
Pharmacogenetics
How variants shape your response to medicine
Genetic variation can affect how your body responds to medicines. Small differences in DNA can change how quickly a drug is processed, how strongly it works, or how sensitive you are to side effects. This helps explain why the same treatment can work well for one person, seem less helpful for another, or feel harder to tolerate, even when they take the same medication.
What is Pharmacogenetics?
Pharmacogenetics examines how genetic differences affect the way a person responds to medications. It studies relationships between genes and drugs to better explain why the same treatment may work differently from one person to another. For many medicines, genes can influence how strongly a drug works or how the body handles it. This understanding can help support treatment decisions that are better informed and more individualized. More detailed information about this topic is available in the LearnHub.
Drugs influenced by the NAA25 gene
When should I seek medical advice?
There is not yet a broadly confirmed role for this gene in guiding how medicines are chosen or used, so questions about side effects, new symptoms, or whether a treatment is right for you are best discussed with your doctor.
