The IFT70A gene helps build and maintain cilia, tiny structures on cells that act like sensors during growth and organ development. The protein made by this gene helps your cells move important materials along cilia so signals reach the right place. If the IFT70A gene does not work properly, cilia may not function as they should, which can contribute to inherited conditions that affect bone growth and sometimes other parts of the body.
What is a gene?
A gene is a stretch of DNA that gives your cells information they can use to make molecules or regulate processes in the body. Some genes provide the instructions for making proteins, which are the working parts of cells. Other genes mainly direct when certain processes happen, where they take place, and how active they are. Together, genes affect how the body develops and functions, and they can also shape how you respond to food, stress, or medications. For a deeper look at this topic, you can find more in the LearnHub.
Overview
IFT70AGene function
What if the gene works
The IFT70A gene helps build and maintain cilia, the tiny hair-like structures on many cells. These structures help cells sense signals. They also support normal development and tissue function.
Risk
What if the gene does not work
Changes in the IFT70A gene can weaken how cells build and maintain tiny hair-like cilia. Milder to more severe variants may reduce this transport system to different degrees, changing how strongly the protein supports cilia function.
Treatment
What does that mean for your treatment
No IFT70A-specific treatment or management approach is currently established. If you carry a pathogenic variant in the IFT70A gene, treatment is guided by the symptoms and organs affected rather than by a drug choice linked to this gene.
Gene function
What if the gene works
Many cells rely on the IFT70A gene to build and maintain cilia, the tiny hair-like structures on the cell surface. These structures help cells sense their surroundings and support movement of fluids in some tissues. Understanding IFT70A gene function helps explain how cilia stay supplied with the parts they need for everyday work.
The IFT70A gene helps deliver key building parts to a growing cilium. This supports the step-by-step assembly of the cilium's inner framework.
Inside cilia, the IFT70A gene is part of the transport machinery that carries proteins to the right place. This steady movement helps cilia stay active as cell sensors.
After a cilium is formed, the IFT70A gene supports ongoing replacement and recycling of cilia parts. This helps many cells keep these structures working over time.
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, or how the body responds to environmental influences. Many variants do not have any noticeable effect and simply represent natural genetic variation. In some cases, 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 IFT70A gene can change the protein’s shape or stability, which may weaken how it joins the cilia transport machinery in tiny hairlike cell structures. Milder variants may partly reduce protein interactions, while more disruptive variants can sharply lower protein levels or stop the protein from working. This helps explain how IFT70A gene variants affect cilia transport, making movement of cell cargo less efficient and less stable.
How variants are linked to conditions
IFT70A does not yet have a broadly confirmed link to a specific health condition in human genetics, although research on how variants of the IFT70A gene are linked to conditions is still evolving. If you have a reported IFT70A variant, your doctor or genetic counselor can explain what it may mean in the context of your symptoms and family history.
A variant is not necessarily a diagnosis
Genetic variants are a usual part of human biology and are common across 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, especially when several genes and environmental factors are involved. In some situations, however, 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 risks related to the IFT70A gene. Anyone with concerns about personal or family risk can speak with a doctor or genetic counselor.
Inheritance of IFT70A variants
There is not yet a broadly confirmed disease specific inheritance pattern for the IFT70A gene, so how IFT70A gene variants are inherited in relation to a defined condition is still being clarified. IFT70A is located on an autosome rather than a sex chromosome, which means a person inherits one copy from each parent. As research develops, a clearer pattern may emerge for particular IFT70A related findings.
What does my IFT70A result mean for my family?
There is not yet a broadly confirmed inheritance pattern tied to a specific condition for IFT70A, though this can change as research develops. If you have a specific IFT70A result and questions about what it could mean for your family, a doctor or genetic counselor can explain it in the context of your personal and family history.
Genetic information
Genetic testing
How you find out about variants
Testing for variants in the IFT70A gene usually uses a blood or saliva sample, and a lab reads the DNA code to look for changes linked to inherited conditions. IFT70A genetic testing can confirm a known family variant or help explain a pattern of symptoms, and results may show a harmful variant, a likely harmful variant, an uncertain finding, or a harmless change.
When should I consider getting a genetic test?
There is not yet a broadly established, IFT70A-specific reason for genetic testing in routine care. Decisions about testing are best made with a doctor or genetic counselor, based on your symptoms, medical history, and family history.
A genetic result is only one part of your health story
A genetic result can provide useful insight, but what it can tell you varies with the condition and the specific type of variant involved. How the body functions over time is also shaped by many influences, including lifestyle, environment, age, and medical history. In some conditions, especially those affected by many genes, genetic information offers context rather than certainty and is best considered together with other parts of care. In other situations, a genetic result can give a clear answer. In areas such as 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. Some people break down a drug more quickly or more slowly, while others may be more or less sensitive to its effects. This helps explain why the same treatment can work well for one person but cause fewer benefits or more side effects in another.
What is Pharmacogenetics?
Pharmacogenetics examines how differences in genes affect the way people respond to medicines. It studies the relationship between genes and drugs to help explain why the same treatment can work differently from one person to another. For many medications, genes influence how the body processes a drug or how strong its effects are. This information can support treatment decisions that are more informed and more individualized. More on this topic is available in the LearnHub.
Drugs influenced by the IFT70A gene
When should I seek medical advice?
There is not yet a broadly confirmed role for this gene in how people respond to medicines, so general medication concerns, unexpected side effects, or questions about starting a new treatment are best discussed with your doctor.
