The IFT22 gene helps cells build and maintain cilia, the tiny hair-like structures that act like sensors and help move signals across the cell surface. The protein made by this gene helps your cells manage intraflagellar transport, the delivery system that keeps cilia working. If the IFT22 gene does not work properly, cilia may not form or function as they should, which can disrupt cell signaling and normal development. This gene is mainly known in cilia research rather than in everyday public discussions.
What is a gene?
Genes are sections of DNA that carry instructions your cells use to make molecules or regulate processes in the body. Some genes provide the directions for making proteins, which are the working parts of cells. Other genes mainly help control when certain processes happen, where they happen, and how strongly they operate. Together, genes affect how the body develops and works, and they can influence how you respond to food, stress, or medications. For a more in depth look at this topic, you can find more in the LearnHub.
Overview
IFT22Gene function
What if the gene works
The IFT22 gene helps cells build and maintain cilia, tiny structures that sense signals and move fluid. Its protein supports intraflagellar transport, the delivery system that moves materials along cilia.
Risk
What if the gene does not work
Changes in the IFT22 gene can range from milder to more severe variants. These changes may partly reduce or more strongly disrupt transport inside cilia, affecting how cells build, maintain, and use these tiny cell antennas.
Treatment
What does that mean for your treatment
For people with a pathogenic variant in the IFT22 gene, no IFT22-specific treatment or drug selection approach is currently established in clinical guidelines.
Gene function
What if the gene works
Many cells use tiny structures called cilia to sense their surroundings and pass along signals. The IFT22 gene helps keep traffic moving inside these structures so they can be built, maintained, and used in everyday cell work. Understanding how the IFT22 gene helps cilia work makes it easier to see how cells manage steady, organized movement of important materials.
The IFT22 gene helps move materials within cilia, the tiny structures many cells use to sense signals and their environment. This steady transport supports normal day to day cell communication.
Cells use the IFT22 gene to deliver parts needed for cilia growth and routine renewal. This helps each cilium keep its shape and stay ready for everyday work.
Its protein acts like a small switch that helps organize intraflagellar transport (the cargo system inside cilia). By guiding transport steps, it supports smooth cilia function.
What is a variant?
A genetic variant is a minor change in the DNA sequence within a gene. These changes are common and are part of normal human diversity, including differences in appearance, metabolism, or the way the body responds to environmental influences. Many variants do not cause any noticeable effects and simply reflect natural genetic variation. In some situations, though, a variant can change how a gene works more substantially and may contribute to or cause a genetic condition.
Genetic variants
What if the gene does not work
Variants in the IFT22 gene can change the protein’s shape, stability, or ability to bind GTP, a small molecule that helps it switch between active and inactive states. Some IFT22 gene variants may have milder effects and only partly reduce activity, while more disruptive variants can shorten the protein, prevent proper folding, or weaken its interactions with the cell’s cilia transport machinery. This is how variants in the IFT22 gene affect protein function at a cellular level.
How variants are linked to conditions
At present, the IFT22 gene does not yet have a broadly confirmed link to a specific health condition in human genetics, although research can evolve over time. Information about IFT22 gene variants and health conditions is still developing, so anyone with a confirmed IFT22 finding should rely on guidance from their doctor or genetic counselor for personal interpretation.
A variant is not necessarily a diagnosis
Genetic variants are a normal feature of human biology and are common throughout the general population. Most do not have a direct effect on health and simply reflect natural human diversity. For many genes, carrying a variant associated with a condition suggests a possible link rather than a definite diagnosis, particularly when several genes and environmental factors are involved. In some situations, though, one 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 IFT22 gene. People with concerns about personal or family risk can talk with a doctor or genetic counselor for advice based on their own history.
Inheritance of IFT22 variants
At this stage, the inheritance of the IFT22 gene variants is not linked to a single, broadly confirmed Mendelian condition, so no one pattern such as autosomal dominant or autosomal recessive is firmly established. The IFT22 gene is located on an autosome, which means you inherit one copy from each parent. In practice, this means family passing patterns for IFT22 are not yet defined in the same clear way as they are for well established single gene conditions.
What does my IFT22 result mean for my family?
There isn't yet a broadly confirmed inheritance pattern tied to a specific condition for IFT22, though this understanding can change as research develops. If you have a specific IFT22 result and questions about what it could mean for your family, a doctor or genetic counselor can help explain it in the context of your personal and family history.
Genetic information
Genetic testing
How you find out about variants
To find out whether you carry a variant in the IFT22 gene, IFT22 genetic testing analyzes DNA from blood, saliva, or a cheek swab. The lab reads the gene’s sequence and compares it with a reference to look for changes. Results may show a benign variant, a variant known to cause a condition, or a variant with unclear meaning.
When should I consider getting a genetic test?
There isn't yet a broadly established, IFT22-specific clinical reason for genetic testing. Testing is usually considered as part of a broader genetic evaluation when someone has symptoms or a family history suggesting an inherited condition, and the decision is best made with a doctor or genetic counselor.
A genetic result is only one part of your health story
A genetic result may give valuable insight, but what it can tell you depends on the condition and on the kind of variant involved. Many factors also influence how the body works over time, including lifestyle, environment, age, and medical history. For some conditions, especially those shaped by many genes, genetic information provides context rather than certainty and is most useful when considered alongside other parts of care. In other situations, a genetic result can offer a clear answer. In areas like medication response, genetic results may also help put individual experiences into context.
Pharmacogenetics
How variants shape your response to medicine
Genetic variation can affect how your body responds to medicines. Small differences in genes can change how quickly a drug is processed, how strongly it acts, or how likely side effects are. This helps explain why the same treatment works well for one person, seems less effective for another, or feels harder to tolerate, even when they take it the same way.
What is Pharmacogenetics?
Pharmacogenetics examines how differences in genes can shape a person’s response to medications. It studies the connection between genes and drugs to help explain why the same treatment may work differently in different people. With many medicines, genes can influence how strongly a drug works or how the body handles it. This information can support treatment decisions that are more informed and more individualized.

Drugs influenced by the IFT22 gene
When should I seek medical advice?
There is not yet a broadly confirmed role for this gene in guiding medication choice or predicting how medicines will work. Questions about side effects, drug interactions, or changes in how well a treatment is working are best discussed with your doctor or pharmacist.
