The NDUFA10 gene helps mitochondria, the parts of your cells that make energy, run one of the main steps in energy production. This gene plays an important role in keeping energy supply steady, especially in organs that need a lot of fuel, like the brain and muscles. If it does not work properly, cells may make less energy, which can lead to a mitochondrial condition with developmental delay, weakness, movement problems, seizures, or heart involvement.
What is a gene?
A gene is a stretch of DNA that carries instructions your cells can use to make molecules or regulate processes in the body. Some genes hold the directions for producing proteins, the parts of cells that do much of the work. Other genes mainly help determine when, where, and how strongly certain processes take place. Together, genes affect how the body develops and functions, and they can influence how you respond to food, stress, or medications. For a deeper look at this topic, you can find more in LearnHub.
Overview
NDUFA10Gene function
What if the gene works
The NDUFA10 gene helps mitochondria, the cell's energy centers, run one of the first steps in energy production. This supports steady energy supply, especially in the brain and muscles.
Risk
What if the gene does not work
More disruptive variants in the NDUFA10 gene can cause mitochondrial complex I deficiency, often affecting the brain and muscles. Symptoms may include developmental delay, low muscle tone, movement problems, or Leigh syndrome, with severity ranging from mild to severe.
Treatment
What does that mean for your treatment
At present, a pathogenic or loss-of-function variant in the NDUFA10 gene does not have an established NDUFA10-specific treatment or drug-choice guideline. Care usually follows general mitochondrial disease management rather than a gene-directed therapy.
Gene function
What if the gene works
NDUFA10 helps your cells make energy inside mitochondria, the parts of cells that supply most usable fuel. It is part of a protein group called complex I, an early step in the chain of reactions that turns food into usable energy. This supports steady cell energy production throughout the body.
The NDUFA10 gene is part of complex I in mitochondria. As this complex works, it helps pass energy from food-derived molecules into the cell’s energy-making system.
Its protein helps complex I keep the right shape and stay connected to nearby parts. This lets the cell’s energy machinery work in a stable, coordinated way.
By supporting one of the first energy-transfer steps in mitochondria, the NDUFA10 gene helps create a stored energy gradient across an inner membrane. Your cells use that gradient to make ATP, the main fuel for everyday work.
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, including differences in appearance, metabolism, or how the body responds to environmental influences. Many have no noticeable effect and are simply part of natural genetic variation. Sometimes, 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 NDUFA10 gene can change the protein’s shape or stability, making it harder for this part of mitochondrial complex I, part of the cell's energy system, to assemble and work normally. Milder variants may leave some activity, while more disruptive variants can sharply reduce complex I function and cell energy production. This helps explain how NDUFA10 gene variants affect mitochondria and why features of mitochondrial complex I deficiency can appear earlier or be more pronounced in some people.
How variants are linked to conditions
Pathogenic variants in both copies of the NDUFA10 gene can cause a rare inherited mitochondrial condition in the complex I deficiency group, sometimes diagnosed as Leigh syndrome. In medical genetics, reports of NDUFA10 gene variants linked to Leigh syndrome usually involve harmful changes in both copies of the gene. These conditions often start in infancy or childhood, and the exact symptoms and severity can vary.
A variant is not necessarily a diagnosis
Genetic variants are a routine part of human biology and are widely seen in the general population. Most do not have a direct impact on health and simply reflect natural variation among people. For many genes, having a variant associated with a condition suggests a possible link rather than a certain diagnosis, especially when several genes and environmental factors play a role. In some situations, 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?
There is not yet broadly confirmed evidence on specific factors that increase or reduce health risk related to the NDUFA10 gene. For many living with a disease-causing NDUFA10 change, risk is mainly shaped by the inherited gene change itself rather than lifestyle, and a doctor or genetic counselor can help explain personal and family risk.
Inheritance of NDUFA10 variants
Variants in the NDUFA10 gene are inherited in an autosomal recessive pattern. This means a person usually develops an NDUFA10-related condition only if they inherit one changed copy from each parent. Parents who each carry one variant are often unaffected, but with each pregnancy there is a 25% chance their child will inherit both changed copies, a 50% chance the child will be a carrier, and a 25% chance the child will inherit neither variant. Sons and daughters are affected equally because the NDUFA10 gene is on an autosome, not a sex chromosome.
What does my NDUFA10 result mean for my family?
For NDUFA10, the main family pattern linked to illness is recessive, which usually means parents are healthy carriers and brothers or sisters may also be affected or be carriers. Close relatives may want to learn whether the same gene change runs in the family, especially if there is a history of similar symptoms. Children of someone with a NDUFA10-related condition would usually be carriers unless the other parent also carries a changed copy.
Genetic information
Genetic testing
How you find out about variants
To look for changes in the NDUFA10 gene, doctors use NDUFA10 genetic testing as part of a multigene panel, exome sequencing, or genome sequencing from a blood sample, saliva sample, or cheek swab. The lab reads the DNA code and compares it with the usual sequence to identify variants that may help explain symptoms or clarify family risk.
When should I consider getting a genetic test?
Genetic testing may be considered if a child or adult has signs of a rare inherited mitochondrial condition, such as developmental delay, seizures, movement problems, or muscle weakness, especially when similar problems run in the family. NDUFA10 is usually checked as part of a broader mitochondrial or brain-related gene panel rather than on its own.
A genetic result is only one part of your health story
Genetic results can provide meaningful insight, but how much they reveal depends on the condition and the type of variant involved. Many other 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 most useful when viewed alongside other parts of care. In other situations, a genetic result may offer a clear answer. In areas such as medication response, these results can help put individual experiences into perspective.
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 absorbs, breaks down, transports, or responds to a drug, so the same treatment may work well for one person but less well for another. These differences are common and can influence both how much benefit a medicine provides and how likely someone is to have side effects.
What is Pharmacogenetics?
Pharmacogenetics examines how genetic differences can affect a person’s response to medications. It studies gene and drug patterns to better understand 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 handles it. This information can support treatment decisions that are more informed and more personalized.

Drugs influenced by the NDUFA10 gene
When should I seek medical advice?
There is not yet a broadly confirmed role for this gene in guiding how medicines are used. Talk with your doctor about any medication concerns, especially if you have troubling side effects, feel worse after starting a new treatment, or are thinking about stopping or changing a medicine.
History
In recent decades, awareness of the NDUFA10 gene’s role has grown. It was identified during efforts to map the many protein parts that make up mitochondrial complex I, a key energy producing system in cells. Early studies focused on describing this protein as one of several small building blocks within that larger complex. From these first observations, research expanded steadily as genetic methods improved and linked changes in NDUFA10 to inherited mitochondrial disease in some families. Over time, descriptions became more precise, moving from protein catalogs to DNA based testing. These historical steps shaped today’s understanding of NDUFA10 as a medically relevant mitochondrial gene.
