The IFT52 gene helps build and maintain cilia, the tiny hair-like structures that help cells sense their surroundings and move fluid. If this gene does not work properly, cilia may not form or function well, which can lead to a ciliopathy, a group of conditions that can affect growth, breathing, vision, kidneys, or development. This gene plays an important role in tissues that rely on cilia every day. Disease-causing variants in the IFT52 gene are uncommon, and their effects can differ from person to person.
What is a gene?
Genes are sections of DNA that hold instructions cells use to make molecules or regulate activities in the body. Some genes provide the instructions for producing proteins, which do much of the work inside cells. Others are mainly involved in controlling when specific processes happen, where they take place, and how active they are. Taken together, genes affect how the body grows and works, and they can influence how you respond to food, stress, and medicines. More detail on this topic is available in the LearnHub.
Overview
IFT52Gene function
What if the gene works
The IFT52 gene helps build and maintain cilia, the tiny hair-like structures on many cells. These structures help cells sense signals and move fluid, especially in the airways, brain, and reproductive system.
Risk
What if the gene does not work
More disruptive variants in the IFT52 gene can cause a ciliopathy, often with short ribs, a narrow chest, extra fingers or toes, and breathing problems; milder variants may lead to retinal, kidney, or liver involvement.
Treatment
What does that mean for your treatment
No IFT52-specific treatment or management approach is currently established. The IFT52 gene is mainly being studied for its role in cilia, and current care is guided by a person’s symptoms rather than a gene-directed drug choice.
Conditions associated with IFT52
Gene function
What if the gene works
Many cells rely on tiny hairlike structures called cilia to sense their surroundings and, in some tissues, move fluid. The IFT52 gene helps run the transport system that builds and maintains these structures. When this process is working normally, cilia keep the right parts in the right place and support everyday cell function.
The IFT52 gene helps gather and position the parts needed to build a cilium. This lets cells form these tiny hairlike structures in an orderly way.
Inside cilia, the IFT52 gene supports a shuttle system that moves proteins to where they are needed. This steady delivery helps cilia grow, work, and renew their parts.
Your cells use the IFT52 gene to maintain cilia over time by keeping materials moving inside them. This ongoing support is a key part of what the IFT52 gene does in the body.
What is a variant?
A genetic variant is a small change in the DNA sequence within a gene. These changes are common and are part of normal human diversity, including differences in appearance, metabolism, and how the body responds to environmental influences. Many variants do not cause any noticeable effects and simply reflect natural genetic variation. In some instances, though, a variant can change a gene’s function more significantly and may contribute to or cause a genetic condition.
Genetic variants
What if the gene does not work
Variants in the IFT52 gene can make the protein unstable, shorten it, or stop it from joining the transport machinery that builds and maintains cilia, the tiny hair-like structures on cells. Milder changes may leave some activity, while more disruptive variants can sharply reduce or eliminate it. This range helps explain how IFT52 gene variants affect protein function and, in conditions linked to IFT52, may influence which features appear and how early they begin.
How variants are linked to conditions
The best-established IFT52 gene variants linked to conditions are rare ciliopathies caused by pathogenic variants inherited in both copies of the gene. These include short-rib thoracic dysplasia, which can involve a narrow chest, short limbs, extra fingers or toes, and sometimes kidney, liver, or eye changes. A small number of people with pathogenic variants in the IFT52 gene have also had primary ciliary dyskinesia, with ongoing sinus or chest infections. These diagnoses are very rare.
A variant is not necessarily a diagnosis
Variants in genes are a normal feature of human biology and are common across the general population. Most do not have a direct effect on health and simply reflect natural human variation. For many genes, carrying a variant associated with a condition suggests a possible link rather than a definite diagnosis, especially when several 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 isn't yet broadly confirmed evidence on specific factors that increase or reduce health risk related to the IFT52 gene. In most cases, any risk is mainly tied to the particular gene change itself rather than clear lifestyle or environmental factors, so people with concerns about personal risk can speak with a doctor or genetic counselor.
Inheritance of IFT52 variants
IFT52-related conditions are inherited in an autosomal recessive pattern. This means a child inherits one altered copy of the IFT52 gene from each parent, and the parents are usually healthy carriers. When both parents carry an IFT52 gene variant, each pregnancy has a 25% chance of resulting in an affected child, a 50% chance of a child who is also a carrier, and a 25% chance of a child who inherits neither altered copy. In practical terms, IFT52 gene inheritance often appears unexpectedly in a family because carriers usually do not have symptoms.
What does my IFT52 result mean for my family?
Changes in the IFT52 gene are linked to a rare inherited condition that usually runs in families in a recessive way. For family members, this often means parents can be healthy carriers, and brothers or sisters may also be affected or be carriers. Other relatives may also carry the same gene change, especially on the same side of the family.
Genetic information
Genetic testing
How you find out about variants
To find variants in the IFT52 gene, genetic testing for IFT52 variants usually uses a blood or saliva sample. A lab reads the DNA code in this gene and looks for changes linked to health conditions. Results may identify a disease causing variant, a harmless variant, or a finding that still needs interpretation.
When should I consider getting a genetic test?
Genetic testing for the IFT52 gene may be worth discussing if a child or family member has signs of a rare inherited condition affecting vision, kidneys, breathing, or bone growth, especially when similar problems run in the family. It can help clarify whether IFT52 is part of the cause.
A genetic result is only one part of your health story
A genetic result can be very informative, but how much it explains varies based on the condition and the specific type of variant. How the body functions over time is also shaped by many other factors, 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 useful 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 into context.
Pharmacogenetics
How variants shape your response to medicine
Genetic variation can affect how your body responds to medicines. Some people break down a drug faster or slower than others, so the same treatment may work differently from one person to the next. These inherited differences are common and can influence how much benefit a medicine provides or how sensitive someone is to side effects. Medication response also depends on other factors, including age, liver and kidney function, and other medicines you take.
What is Pharmacogenetics?
Pharmacogenetics examines how differences in genes can shape a person’s response to medications. It looks at gene and drug patterns to better understand why the same treatment may work differently from one person to another. For many medicines, genes can influence how strongly a drug works or how the body handles it. This information can support more informed and more individualized treatment decisions.

Drugs influenced by the IFT52 gene
When should I seek medical advice?
There is no broadly confirmed role for this gene in guiding medication response at this time, so questions about symptoms, side effects, or how a treatment is working are best discussed with your doctor.
