The CHCHD10 gene helps mitochondria, the parts of cells that make energy, stay healthy, especially in nerve and muscle cells. If this gene does not work well, cells may struggle to meet energy needs and may be more likely to break down over time. Pathogenic variants in the CHCHD10 gene are linked to some inherited conditions affecting movement, muscle strength, breathing, and, in some families, frontotemporal dementia or ALS (a nerve disease that affects muscle control). Many variants are harmless, while a few may change how the gene supports these high-energy tissues.
What is a gene?
Genes are sections of DNA that give your cells instructions for making molecules or directing processes in the body. Some genes carry the code for proteins, which are the parts of cells that do much of the work. Others mainly regulate the timing, place, and intensity of certain processes. Together, genes affect how the body develops and functions, and they can influence how you respond to food, stress, or medications.

Overview
CHCHD10Gene function
What if the gene works
The CHCHD10 gene helps keep mitochondria, the cell’s energy makers, working normally. Its protein supports the inner structure of mitochondria and helps cells make energy, especially in tissues with high energy needs such as muscles and nerves.
Risk
What if the gene does not work
Variants in the CHCHD10 gene can impair mitochondrial function, especially in nerve and muscle cells. Depending on the variant, effects may range from later-onset muscle weakness or balance problems to motor neuron disease or frontotemporal dementia.
Treatment
What does that mean for your treatment
At present, no CHCHD10-specific treatment or drug selection approach is established for people with a pathogenic or loss of function variant in the CHCHD10 gene. Research is studying CHCHD10 as part of mitochondrial problems in ALS and related neurologic conditions, but this has not changed routine care.
Conditions associated with CHCHD10
Gene function
What if the gene works
Your cells need healthy mitochondria to make steady energy. In your body, the CHCHD10 gene supports processes that keep these energy centers organized and ready to work. Its protein sits inside mitochondria near the folded inner membrane, where much of the cell’s energy is made.
The CHCHD10 gene helps mitochondria keep their inner membrane neatly folded and supported. Those folds create the working surface where the cell’s energy-making machinery is arranged.
By keeping mitochondrial structure in order, this gene helps cells make usable energy from food and oxygen. This is a key part of how the CHCHD10 gene works in mitochondria during everyday cell activity.
Its protein works with other mitochondrial proteins to keep these structures stable and well organized. This steady setup helps mitochondria run smoothly across many cell types.
What is a variant?
A genetic variant is a small difference in the DNA sequence within a gene. These differences are common and are part of normal human diversity, including variation in appearance, metabolism, and 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 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 CHCHD10 gene can change the protein's shape, stability, or amount, which helps explain how CHCHD10 gene variants affect protein function inside mitochondria, the cell's energy centers. Some milder variants partly reduce activity, while more disruptive variants can cause the protein to misfold, clump, or interfere with the membrane folds inside mitochondria. That broader functional impact may be linked to earlier or more severe nerve and muscle disease in some people.
How variants are linked to conditions
Pathogenic variants in the CHCHD10 gene are linked to a group of inherited nerve and muscle conditions, including mitochondrial myopathy and some forms of motor neuron disease. In some families, CHCHD10 gene variants have also been associated with amyotrophic lateral sclerosis, frontotemporal dementia, or a late onset spinal motor neuropathy. The exact diagnosis and symptoms can vary from one person or family to another.
A variant is not necessarily a diagnosis
Genetic variants are a routine part of human biology and are widely found in the general population. Most have no direct effect on health and simply reflect natural human diversity. For many genes, carrying a variant associated with a condition points to a possible link rather than a definite diagnosis, especially when multiple genes and environmental factors contribute. 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 risks linked to the CHCHD10 gene. For families with a disease-causing CHCHD10 change, risk is mainly tied to the inherited variant itself, while the age symptoms begin and how severe they are can vary. Anyone worried about personal or family risk can speak with a doctor or genetic counselor.
Inheritance of CHCHD10 variants
For families asking how CHCHD10 gene variants are inherited, the best established pattern is autosomal dominant. This means a person with a disease causing variant in one copy of the CHCHD10 gene can pass it to a child, and each pregnancy carries a 50% chance of inheriting that same variant. Sons and daughters are affected in the same way because the CHCHD10 gene is on chromosome 22, not a sex chromosome.
What does my CHCHD10 result mean for my family?
A disease-causing change in the CHCHD10 gene usually has implications for close relatives because this gene is most often linked to conditions that can be passed down in a dominant way. That means parents, brothers, sisters, and children may also carry the same change, even if symptoms are different or have not started yet. In families with a confirmed CHCHD10-related condition, relatives may want to discuss whether the result could apply to them too.
Genetic information
Genetic testing
How you find out about variants
To find out whether you carry a variant in the CHCHD10 gene, a lab can do genetic testing for CHCHD10 variants using a blood sample or saliva. The test reads the DNA sequence of the CHCHD10 gene and looks for changes that may help explain a person’s symptoms or family history.
When should I consider getting a genetic test?
Testing for CHCHD10 may be worth discussing if you or close relatives have inherited nerve or muscle problems, especially ALS, certain inherited forms of dementia, unexplained muscle weakness, or balance and walking problems that run in the family. A result can help show whether these symptoms are part of an inherited condition.
A genetic result is only one part of your health story
Genetic results can offer useful insight, but how much they reveal depends on the condition and the type of variant involved. How the body works over time is shaped by many factors, including lifestyle, environment, age, and medical history. In some conditions, especially those influenced by many genes, genetic information provides context rather than certainty and is best understood along 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 individual experiences into context.
Pharmacogenetics
How variants shape your response to medicine
Genetic variation can affect how people respond to medicines. This helps explain why the same treatment may work well for one person but less well for another, or why some people are more likely to notice side effects. 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. These differences are common and can influence how well a medicine works or how sensitive someone is to it.
What is Pharmacogenetics?
Pharmacogenetics examines the way genetic differences can affect how a person responds to medications. By looking at connections between genes and drugs, it helps explain why the same treatment can work differently from one person to another. For many medicines, genes influence either how strongly a drug works or how the body handles it. This information can support treatment decisions that are more informed and more individualized. You can read more about this topic in the LearnHub.
Drugs influenced by the CHCHD10 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 adjusted, so questions about side effects, trouble tolerating a treatment, or whether a medicine is helping are best discussed with your doctor.
History
The CHCHD10 gene entered medical research more recently than many well-known inherited genes. In 2014, researchers linked variants in the CHCHD10 gene to some families with frontotemporal dementia and amyotrophic lateral sclerosis, helping connect a single gene to a mixed pattern of brain and nerve disease. From these first observations, research expanded steadily. Later studies also connected the CHCHD10 gene with certain inherited muscle and mitochondrial conditions, though the range of linked features became clearer over time. The way this gene was viewed has shifted over time, as some early reports were refined and not every proposed link held up equally well in larger studies. Today, CHCHD10 remains an active area of research in neurogenetics.
