The AURKAIP1 gene helps mitochondria, the energy centers inside cells, make proteins they need to produce energy. If this gene does not work properly, especially when both copies carry a harmful variant, the body may not make enough energy for steady growth and development. The protein made by this gene helps your cells build part of the protein making machinery inside mitochondria, so affected people may have low muscle tone, developmental delay, or heart problems.
What is a gene?
A gene is a stretch of DNA that gives your cells instructions for making molecules or guiding processes in the body. Some genes carry the directions for producing proteins, the functional parts of cells. Other genes mostly regulate when certain processes happen, where they occur, and how strongly they act. Together, genes affect how the body develops and works, and they can influence how you respond to food, stress, or medications. To explore this topic in more detail, you can learn more in the LearnHub.
Overview
AURKAIP1Gene function
What if the gene works
The AURKAIP1 gene helps mitochondria, the cell’s energy centers, make some of the proteins they need. This supports normal energy production, especially in tissues with high energy needs such as the brain, muscles, and heart.
Risk
What if the gene does not work
More disruptive variants in the AURKAIP1 gene can cause a mitochondrial condition, often starting in infancy, with poor growth, low muscle tone, developmental delay, and high lactic acid levels. Milder variants may lead to later onset or less severe features.
Treatment
What does that mean for your treatment
No AURKAIP1-specific treatment or management approach is currently established, so care is based on the person’s symptoms and general supportive treatment rather than on a drug choice tied to the AURKAIP1 gene itself.
Gene function
What if the gene works
Your cells need a steady energy supply for everyday work. Inside mitochondria, the parts of cells that help release energy from food, the AURKAIP1 gene helps make a small group of proteins that support this process. Understanding AURKAIP1 gene function in mitochondria helps explain how cells keep energy production running smoothly.
The AURKAIP1 gene helps build and steady a small protein making machine inside mitochondria. This machine reads instructions stored in mitochondrial DNA so the right proteins can be made in the right place.
Inside mitochondria, this gene supports translation (the step where cells read genetic instructions to make proteins). The proteins made there become key working parts of the cell’s energy system.
By helping mitochondria make their own proteins, the AURKAIP1 gene supports steady energy production. This matters most in tissues with constant energy needs, such as the brain, heart, and muscles.
What is a variant?
Genetic variants are small changes in a gene’s DNA sequence. These changes are common and are part of normal human diversity, such as differences in appearance, metabolism, or 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
In people with pathogenic changes, how AURKAIP1 gene variants affect protein function usually comes down to reduced or absent AURKAIP1 protein, which can impair mitochondrial protein synthesis and lower the amount of key energy-making proteins in the cell. Milder variants may leave some activity, while more severe variants, including changes that truncate the protein or disrupt splicing, can cause a larger drop in this process. When both copies are strongly affected, the linked mitochondrial condition often appears earlier and may be more severe.
How variants are linked to conditions
Pathogenic variants in the AURKAIP1 gene can cause a very rare inherited mitochondrial disease, usually described as combined oxidative phosphorylation deficiency. In reported families, AURKAIP1 gene variants linked to mitochondrial disease have been associated with developmental delay, low muscle tone, poor growth, feeding difficulties, and raised lactate levels, though severity varies from person to person.
A variant is not necessarily a diagnosis
Gene variants are a normal feature of human biology and are widespread in the general population. Most of these variants do not have a direct impact on health and instead represent natural human diversity. For many genes, carrying a variant associated with a condition suggests a possible link rather than a definitive diagnosis, especially when several genes and environmental factors also contribute. In some situations, though, a single well characterized variant in a particular 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 AURKAIP1 gene. If a change in AURKAIP1 is found on genetic testing, a doctor or genetic counselor can help explain what it may mean for you and your family.
Inheritance of AURKAIP1 variants
AURKAIP1-related conditions are inherited in an autosomal recessive pattern. This means a child inherits one AURKAIP1 gene variant from each parent. Parents who carry one variant are usually unaffected carriers, and if both parents are carriers, each pregnancy has a 25% chance of an affected child, a 50% chance of a carrier child, and a 25% chance of a child without the familial variants. Because the AURKAIP1 gene is on an autosome rather than a sex chromosome, this AURKAIP1 inheritance pattern is the same for males and females.
What does my AURKAIP1 result mean for my family?
Changes in the AURKAIP1 gene linked to disease are understood to affect families in a recessive pattern. This usually means parents can be healthy carriers, and brothers, sisters, or future children could also carry the same gene change or, in some families, be affected. Because of that, close relatives may also want to learn whether this gene change is present in the family.
Genetic information
Genetic testing
How you find out about variants
Variants in the AURKAIP1 gene are usually found through genetic testing on a blood or saliva sample. For people looking into how AURKAIP1 genetic testing works, labs typically use a multigene panel, exome sequencing, or genome sequencing to read the gene and check for variants.
When should I consider getting a genetic test?
Genetic testing for the AURKAIP1 gene may be considered when a baby or child has signs of a rare inherited condition affecting the body’s energy-making system, such as severe growth problems, feeding trouble, low muscle tone, or developmental delay. It may also be discussed after an affected pregnancy or with a family history of a similar early illness.
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 the kind of variant involved. Over time, many factors shape how the body functions, including lifestyle, environment, age, and medical history. For some conditions, especially those affected by many genes, genetic information offers context rather than certainty and is most helpful when considered alongside 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 in context.
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 bloodstream, or responds to it at its target. This helps explain why the same treatment works well for one person, seems weaker in another, or causes more side effects in someone else. These differences are common and are one reason medication response can vary from person to person.
What is Pharmacogenetics?
Pharmacogenetics is the area of study that looks at how genetic differences affect the way people respond to medications. It examines links between genes and drugs to help explain why the same treatment can work differently from one person to another. For many medicines, genes influence both how strongly a drug works and how the body processes it. This information can help support more informed, more individualized treatment decisions.

Drugs influenced by the AURKAIP1 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 medicines, side effects, or treatment changes are best discussed with your doctor or pharmacist.
