The NDUFB10 gene helps build complex I, one of the parts inside mitochondria that helps cells make energy. If the NDUFB10 gene does not work well, cells may not produce enough energy, especially in the brain, muscles, and inner ear. This gene plays an important role in growth, movement, hearing, and development. Rare variants that disrupt it can cause a mitochondrial condition with developmental delay, seizures, weakness, or hearing loss.
What is a gene?
Genes are stretches of DNA that carry instructions your cells use to make molecules or direct processes in the body. Some genes hold the directions for producing proteins, the parts of cells that do much of the work. Others mainly regulate 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 influence how you respond to food, stress, or medications.

Overview
NDUFB10Gene function
What if the gene works
The NDUFB10 gene helps mitochondria, your cells’ energy centers, run complex I, a key step in making energy. This supports ATP production, the fuel cells use for everyday work.
Risk
What if the gene does not work
Changes in the NDUFB10 gene can reduce cellular energy production and may lead to developmental delay, hearing loss, and brain or heart problems. Effects can range from milder to more severe, with earlier onset often reflecting greater impact.
Treatment
What does that mean for your treatment
No NDUFB10-specific treatment or drug-selection approach is currently established for pathogenic variants in the NDUFB10 gene. Care is supportive and guided by the person’s symptoms, while mitochondrial-targeted treatments for complex I deficiency are still being studied and are not specific to NDUFB10.
Conditions associated with NDUFB10
Gene function
What if the gene works
Your cells need a steady power supply for movement, thinking, and basic organ function. The NDUFB10 gene helps build and support a key energy making machine inside mitochondria, the parts of cells that act like power plants. When it works normally, mitochondrial energy production stays efficient and well organized.
As part of complex I, the NDUFB10 protein supports mitochondrial energy production. It helps your cells move energy from food into a form they can use.
The NDUFB10 protein becomes part of the inner membrane of mitochondria, where complex I sits. It helps this energy making unit assemble and stay stable during routine cell activity.
By supporting complex I activity, NDUFB10 helps mitochondria create a small electrical difference across their inner membrane. Your cells use that stored force to make ATP (the cell's main usable energy source).
What is a variant?
A genetic variant is a small change in the DNA sequence within a gene. These changes are common and help explain 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. 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
NDUFB10 gene variants often make the protein unstable or disrupt how it joins mitochondrial complex I, so the complex is assembled less effectively and its activity drops. Some changes only partly reduce function, while more severe variants can nearly abolish the protein or alter splicing (how RNA instructions are pieced together), leading to a much larger fall in cellular energy production. That range in NDUFB10 gene variant effects can influence how early mitochondrial disease appears and how marked it is.
How variants are linked to conditions
Among conditions linked to NDUFB10 gene variants, the main one is a rare mitochondrial disease called isolated complex I deficiency. Pathogenic variants in the NDUFB10 gene can cause this condition and may lead to developmental delay, low muscle tone, seizures, hearing loss, movement problems, or vision changes. Some people also have heart or breathing involvement, and symptoms can start in infancy, childhood, or later in life.
A variant is not necessarily a diagnosis
Genetic variants are a normal feature of human biology and are common across the general population. Most do not have a direct effect on health and instead reflect natural human diversity. For many genes, carrying a variant associated with a condition indicates a possible link rather than a definitive diagnosis, especially when more than one gene and environmental factors are involved. In some situations, though, a single well characterized variant in a specific 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 factors that increase or reduce health risk related to the NDUFB10 gene. For many living with an NDUFB10-related condition, risk is shaped mainly by the specific gene change a person carries rather than everyday lifestyle factors, and personal guidance from a doctor or genetic counselor can help.
Inheritance of NDUFB10 variants
NDUFB10-related conditions are inherited in an autosomal recessive pattern. This means a person usually inherits one NDUFB10 gene variant from each parent, and parents are often healthy carriers with one changed copy and one working copy. When both parents carry a variant, 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 with no familial variant. In families asking how NDUFB10 variants are inherited, this pattern means boys and girls are affected equally.
What does my NDUFB10 result mean for my family?
For families with a disease-causing NDUFB10 result, the condition is usually inherited in a recessive way, which means close relatives may also be carriers even if they are healthy. Brothers and sisters may sometimes also be affected or carry the same gene change. This can matter for future pregnancies and for relatives who want to better understand their own family planning risks.
Genetic information
Genetic testing
How you find out about variants
To find out whether you carry a variant in the NDUFB10 gene, a lab can do genetic testing for NDUFB10 variants using a blood sample, saliva, or a cheek swab. The test reads the gene’s DNA code and may also check for missing or extra pieces, helping clarify whether a disease-causing variant is present.
When should I consider getting a genetic test?
Genetic testing may be worth considering if there is a personal or family history of an inherited mitochondrial condition, especially with early-life developmental delays, seizures, low muscle tone, or unexplained weakness. Testing for NDUFB10 is usually considered as part of a broader panel when doctors are looking for the cause of these symptoms.
A genetic result is only one part of your health story
Genetic results can provide useful insight, but how much they explain varies by the condition and by the type of variant involved. Many other factors, including lifestyle, environment, age, and medical history, also shape how the body works over time. In 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 can offer 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 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 it at its target. Because of this, the same medication may work well for one person, help less in another, or cause more side effects in someone who is more sensitive to it.
What is Pharmacogenetics?
Pharmacogenetics focuses on how differences in a person’s genes can affect their response to medications. It examines links between genes and drugs to help explain why the same treatment may work differently in different people. For many medicines, genes can influence either how strongly a drug works or how the body handles it. This information can support treatment choices that are both more informed and more individualized. To look into this subject further, more information is available in the LearnHub.
Drugs influenced by the NDUFB10 gene
When should I seek medical advice?
There is not yet a broadly confirmed role for this gene in guiding medication choices, so questions about side effects, new symptoms, or how well a treatment is working are best discussed with your doctor.
History
NDUFB10 entered the medical literature as researchers worked to map the many genes involved in the cell’s energy system. From these first observations, research expanded steadily. As genetic testing improved, rare variants in the NDUFB10 gene were linked to certain mitochondrial conditions, helping doctors connect long-standing symptoms with an underlying inherited cause. This gene has mainly been important within specialist research rather than public awareness campaigns or high-profile news stories. Its history reflects a broader shift in medicine, moving from describing unexplained neurologic and metabolic illness to identifying the specific genes involved.
