The ANKRD24 gene helps support the tiny hair bundles in the inner ear that turn sound vibrations into signals the brain can read. If this gene does not work properly, those structures may be less stable, and inherited hearing loss can develop or gradually worsen over time. Some people first learn about this gene when genetic testing is done for hearing loss that seems to run in a family.
What is a gene?
Genes are sections of DNA that hold instructions your cells use to make molecules or manage activities in the body. Some genes provide the directions for producing proteins, which do much of the cell’s work. Others mostly guide when certain processes happen, where they happen, and how active they are. Taken together, genes affect how your body grows and works, and they can also influence how you respond to food, stress, and medications. To go into this subject in greater detail, you can find more in the LearnHub.
Overview
ANKRD24Gene function
What if the gene works
The ANKRD24 gene helps inner ear hair cells stay stable. Its protein gathers at the base of the tiny sound sensing hairs and supports their rootlets, which helps hearing work normally.
Risk
What if the gene does not work
Milder DNA changes in the ANKRD24 gene may partly reduce the ANKRD24 protein. More severe variants can more strongly disrupt the protein links that help cells keep their internal framework organized and attached in the right place.
Treatment
What does that mean for your treatment
No ANKRD24-specific treatment or drug choice is currently established for pathogenic variants in the ANKRD24 gene. Care is based on the person’s clinical features rather than the variant itself.
Gene function
What if the gene works
In the inner ear, the ANKRD24 gene helps sound sensing cells stay mechanically stable. Its protein gathers where tiny hair-like projections connect to the cell surface. This support is part of the ANKRD24 gene’s role in hearing.
The ANKRD24 gene helps organize the attachment site where tiny hair-like projections on inner ear cells meet the cell surface. This creates a firm base for structures that begin the hearing process.
Its protein helps position strengthening fibers at that base, adding support where bending forces are highest. This helps the sound sensing bundle keep a stable shape during normal movement.
In daily hearing, ANKRD24 supports the controlled motion of inner ear hair cells as sound vibrations pass through. That steady mechanics is part of how the ANKRD24 gene contributes to hearing.
What is a variant?
A genetic variant refers to 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. Sometimes, though, a variant can affect a gene’s function more substantially and may contribute to or cause a genetic condition.
Genetic variants
What if the gene does not work
Research on how variants influence the ANKRD24 gene's function suggests that many DNA changes alter the ANKRD24 protein's shape or stability, especially in its ankyrin repeat regions. Milder variants may leave some function in place but weaken protein interactions or make the protein less stable inside the cell. More severe variants can truncate the protein or stop it from being made, causing a much larger loss of function.
How variants are linked to conditions
Current evidence has not established a broadly confirmed link between variants in the ANKRD24 gene and a specific health condition, although this may change as research grows. Information about ANKRD24 gene variants linked to conditions is still developing, so people with a confirmed ANKRD24 finding should rely on their doctor or genetic counselor for guidance that fits their own health and family history.
A variant is not necessarily a diagnosis
Genetic variants are a routine part of human biology and are widespread in the general population. Most do not have a direct effect on health and instead represent natural human diversity. For many genes, carrying a variant associated with a condition indicates a possible link rather than a definite diagnosis, especially when multiple genes and environmental factors also play a role. 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 ANKRD24 gene. Risk can vary by the exact gene change and family history, so people with questions about their personal risk should speak with a doctor or genetic counselor.
Inheritance of ANKRD24 variants
ANKRD24-related heart muscle disease is inherited in an autosomal dominant pattern. That means a parent with a disease-causing variant in the ANKRD24 gene can pass it to a child, and each pregnancy carries a 50% chance of inheriting that variant. Sons and daughters can inherit it equally, and it can be passed from either parent. This is the main inheritance pattern described for ANKRD24 gene variants linked to arrhythmogenic cardiomyopathy.
What does my ANKRD24 result mean for my family?
For ANKRD24, the best-established family pattern is a dominant form of inherited hearing loss. That means close relatives such as a parent, brother, sister, or child may also carry the same change and may have hearing loss or develop it over time, even if symptoms differ from one person to another. Some families may find that several generations are affected, while in some people the gene change starts new in them rather than being passed down from a parent.
Genetic information
Genetic testing
How you find out about variants
Genetic testing for ANKRD24 variants looks for changes in the ANKRD24 gene by reading your DNA from a blood sample, saliva, or a cheek swab. A lab compares the gene’s sequence with the usual pattern and reports whether a variant was found, often as benign, uncertain, or linked to disease.
When should I consider getting a genetic test?
There is not yet a broadly established ANKRD24-specific reason for genetic testing in routine care. Testing decisions are usually based on your symptoms and family history and are best discussed with a doctor or genetic counselor.
A genetic result is only one part of your health story
A genetic result can be informative, but how much it reveals depends on the condition and on the type of variant involved. Lifestyle, environment, age, and medical history, along with other factors, influence how the body functions over time. In some conditions, especially those shaped by many genes, genetic information provides context rather than certainty and is best understood together with other parts of care. In other situations, a genetic result may offer a clear answer. In areas like medication response, genetic 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. This helps explain why the same medication may work well for one person, have little effect in another, or cause more side effects in someone who is more sensitive to it.
What is Pharmacogenetics?
Pharmacogenetics is the area of study that examines how genetic differences affect the way people respond to medications. It focuses on links between genes and medicines to help explain why the same treatment can work differently from one person to another. For many drugs, genes can influence how strongly a medication works or how the body handles it. This information can support more informed, personalized treatment decisions. More detail on this topic is available in the LearnHub.
Drugs influenced by the ANKRD24 gene
When should I seek medical advice?
There is not yet a broadly confirmed role for this gene in how the body responds to medicines, so questions about symptoms, side effects, or treatment choices are best discussed with your doctor.
