The NAA10 gene helps your cells adjust many newly made proteins so they can work as expected, which supports growth, brain development, and organ function. This gene plays an important role in how proteins are processed after they are made. If the gene does not work properly, some people can have developmental delay, intellectual disability, heart differences, or growth problems, with effects ranging from mild to more marked. Certain variants in the NAA10 gene are linked to rare inherited conditions, including NAA10 related neurodevelopmental syndrome.
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 information needed to produce proteins, which are the parts of cells that do 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 functions, and they can influence how you respond to food, stress, or medications.

Overview
NAA10Gene function
What if the gene works
The NAA10 gene helps cells add a small chemical tag to many newly made proteins. This can affect how long proteins last, where they go, and how well cells grow and function.
Risk
What if the gene does not work
Variants in the NAA10 gene can cause delayed development, intellectual disability, growth problems, and sometimes heart issues. Effects can range from milder to more severe, and the specific variant may influence when features appear and how noticeable they are.
Treatment
What does that mean for your treatment
No treatment or management approach specific to the NAA10 gene is currently established. Care is guided by a person’s symptoms and support needs rather than by a drug choice linked to a variant in the NAA10 gene. The NAA10 gene is also being studied in early-stage research as a possible biomarker and drug target in some cancers.
Conditions associated with NAA10
Gene function
What if the gene works
Inside your cells, the NAA10 gene helps manage many proteins just after they are made. It adds a small chemical tag called an acetyl group to the front end of selected proteins. These early steps show how the NAA10 gene works in cells to prepare proteins for daily use.
The NAA10 gene helps place a small acetyl tag on the front end of many newly made proteins. This often happens while proteins are still being built, which helps set up how they will act in the cell.
This tag can help some proteins stay stable and avoid being cleared away too soon. It supports a balanced protein supply so cells can keep routine work running smoothly.
Acetyl tagging can influence where certain proteins go and which partners they work with. That helps proteins join the right cell pathways at the right time.
NAA10 often works with partner proteins, especially NAA15, in a protein marking group called NatA. This teamwork helps cells modify a large share of fresh proteins efficiently.
What is a variant?
A genetic variant is a minor change in the DNA sequence of a gene. These changes are common and are part of normal human diversity, including differences in appearance, metabolism, and how the body responds to environmental influences. Many variants have no noticeable effect and simply represent natural genetic variation. In some cases, 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
NAA10 gene variants can change the protein’s shape, stability, or ability to join its partner proteins, which often lowers its enzyme activity. Some variants leave partial activity, while more disruptive variants can greatly reduce or stop this activity and may also make the protein break down sooner. This range helps explain why NAA10 related conditions can vary, with milder changes sometimes linked to less marked features and more severe changes often linked to earlier or broader developmental effects.
How variants are linked to conditions
Among the conditions linked to variants in the NAA10 gene, the best established is NAA10-related neurodevelopmental syndrome. Pathogenic variants can cause developmental delay or intellectual disability, low muscle tone, growth problems, and heart findings in some people. Some variants are specifically associated with Ogden syndrome, a severe early-onset form. Features vary widely, especially in females, so a genetic result confirms the diagnosis but does not predict every feature.
A variant is not necessarily a diagnosis
Genetic variants are a usual part of human biology and are widely present in the general population. Most do not have a direct effect on health and simply reflect natural human variation. For many genes, carrying a variant associated with a condition indicates a possible link rather than a definite diagnosis, especially when several genes and environmental factors contribute. In some situations, however, a single well-characterized variant in a particular gene is enough to confirm a diagnosis.
Are there things that can increase or change my risk?
There is not yet broadly confirmed evidence on specific lifestyle or environmental factors that increase or reduce health risk related to the NAA10 gene. For many living with a disease-causing NAA10 change, risk is mainly shaped by the exact genetic change and, in some families, whether the person is male or female.
Inheritance of NAA10 variants
Variants in the NAA10 gene are inherited in an X-linked pattern, which helps explain how variants of the NAA10 gene are inherited through families. Because NAA10 is on the X chromosome, mothers can pass a variant to sons or daughters, while fathers pass their X chromosome only to daughters. In many families, a mother carrying a NAA10 variant has a 50% chance of passing it on with each pregnancy. Some people with a NAA10-related condition have a new, de novo variant that was not inherited from either parent.
What does my NAA10 result mean for my family?
Changes in the NAA10 gene are usually passed down in an X-linked way, so the result can matter for close relatives on the mother’s side of the family. Mothers, sisters, brothers, and children may sometimes carry the same change, although health effects can differ a lot, especially between males and females. Some NAA10 changes happen for the first time in one person, so a parent does not always have the same result.
Genetic information
Genetic testing
How you find out about variants
Testing for variants in the NAA10 gene usually uses a blood sample or cheek swab, and the lab reads the gene’s DNA code to look for changes. NAA10 genetic testing may be done alone or as part of a larger panel, and it can show whether a variant is present.
When should I consider getting a genetic test?
Consider testing for the NAA10 gene when a child has unexplained developmental delay, low muscle tone, growth problems, heart differences, or vision problems, especially if similar issues run in the family. Testing can help confirm whether these features are part of an inherited condition.
A genetic result is only one part of your health story
A genetic result can provide useful insight, but how much it explains depends on the condition and on the kind of variant involved. Over time, many factors, including lifestyle, environment, age, and medical history, influence how the body functions. For some conditions, particularly those shaped by many genes, genetic information offers context rather than certainty and is most helpful when considered with other parts of care. In other situations, a genetic result may give a clear answer. In areas like medication response, genetic results can also help put personal experiences in context.
Pharmacogenetics
How variants shape your response to medicine
Genetic variation can affect how people respond to medicines. Some people break down a drug more slowly or more quickly, while others are more or less sensitive to its effects. This helps explain why the same treatment can work well for one person, cause more side effects in another, or seem to have less benefit in someone else.
What is Pharmacogenetics?
Pharmacogenetics examines how genetic differences affect the way people respond to medications. By studying links between genes and drugs, it helps explain why the same treatment may work differently from one person to another. For many medicines, genes can influence both how strongly a drug works and how the body processes it. This information can support treatment decisions that are more informed and more individualized.

Drugs influenced by the NAA10 gene
When should I seek medical advice?
There is not yet a broadly confirmed role for this gene in guiding medication response. Questions about medicines, side effects, or changes in treatment are best discussed with your doctor.
History
The NAA10 gene entered medical genetics in a notable way in 2011, when researchers linked a variant in this gene to a rare inherited condition later called Ogden syndrome. This finding drew attention because NAA10 was already known in basic science as part of a system that modifies many newly made proteins, and the clinical link connected that laboratory work to human disease. From these first observations, research expanded steadily. Additional reports then showed that changes in the NAA10 gene could be associated with a broader range of developmental and heart related features than first recognized. Over time, descriptions became more precise, and the picture shifted from a single rare syndrome to a wider spectrum of NAA10 related conditions.
