The ADGRF5 gene helps certain cells in the lungs and blood vessels sense signals from their surroundings. The protein made by this gene helps your cells keep lung surfactant in balance, a slippery substance that helps the tiny air sacs stay open. If the ADGRF5 gene does not work properly, surfactant control can be disrupted, which may affect breathing and lung health. Research also suggests this gene supports healthy vessel barriers.
What is a gene?
Genes are sections of DNA that hold instructions your cells use to make molecules or regulate processes in the body. Some genes provide the directions for making proteins, the parts of cells that carry out much of their work. Others mainly control when certain processes happen, where they happen, and how strongly they occur. As a group, genes affect how the body develops and functions, and they can influence how you respond to food, stress, or medications.

Overview
ADGRF5Gene function
What if the gene works
The ADGRF5 gene helps lung cells regulate surfactant, the oily material that keeps air sacs open. It also helps cells send signals at their surface.
Risk
What if the gene does not work
More disruptive variants in the ADGRF5 gene can impair surfactant control in the lungs, leading to pulmonary alveolar proteinosis. Symptoms may range from mild breathing limitation to earlier, more persistent cough, low oxygen levels, and progressive lung disease.
Treatment
What does that mean for your treatment
At present, no treatment or drug choice is guided specifically by pathogenic variants in the ADGRF5 gene. The ADGRF5 gene is being studied as a possible biomarker and drug target in some cancers and lung conditions.
Gene function
What if the gene works
Each breath depends on tiny air sacs staying open and working smoothly. In the lungs, the ADGRF5 gene helps certain lining cells sense signals and keep surfactant levels well controlled. This helps explain what the ADGRF5 gene does in the lungs during normal breathing.
The ADGRF5 gene provides instructions for a receptor on the surface of certain lung cells. This receptor helps the cells sense nearby signals and adjust their activity in a controlled way.
One of the main jobs of the ADGRF5 gene is to help keep lung surfactant in balance. Surfactant is a slippery material that helps the tiny air sacs open easily with each breath.
By helping control surfactant, this gene supports smooth movement of the tiny air sacs during everyday breathing. It helps the lung lining work in a steady, coordinated way as air moves in and out.
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 have any noticeable effect and simply represent natural genetic variation. Sometimes, however, a variant changes how a gene functions more substantially and can contribute to or cause a genetic condition.
Genetic variants
What if the gene does not work
In the ADGRF5 gene, DNA changes can alter how the receptor protein is built, folded, reaches the cell surface, or sends signals. Some milder variants partly reduce activity, while more severe variants can stop the protein from being made or working at all. This range helps explain how ADGRF5 gene variants affect protein function and may influence how early and how strongly lung findings appear in people with pathogenic variants in both gene copies.
How variants are linked to conditions
Current evidence does not yet show a broadly confirmed link between ADGRF5 gene variants and a specific inherited health condition, although this may change as research develops. If you have a confirmed change in the ADGRF5 gene, its meaning is best interpreted in the context of your own medical history and family findings.
A variant is not necessarily a diagnosis
Genetic variants are a routine part of human biology and are widely found in the general population. Most do not have a direct effect on health and simply contribute to normal human diversity. For many genes, having a variant associated with a condition suggests a possible link rather than a definitive diagnosis, especially when multiple genes and environmental factors are involved. In some cases, 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 ADGRF5 gene. If you have a change in ADGRF5 on genetic testing, a doctor or genetic counselor can help explain what it may mean for your personal and family risk.
Inheritance of ADGRF5 variants
There is not yet a broadly confirmed Mendelian pattern for how ADGRF5 gene variants are inherited in relation to a specific human condition. In practice, ADGRF5 gene inheritance is not described as clearly autosomal dominant, autosomal recessive, or X linked in the way it is for many well-established genetic conditions. The ADGRF5 gene is located on chromosome 6, which is an autosome, so you inherit one copy from each parent.
What does my ADGRF5 result mean for my family?
There is not yet a broadly confirmed inheritance pattern tied to a specific health condition for ADGRF5, and this can change as research develops. If you have a specific ADGRF5 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
Genetic testing for variants in the ADGRF5 gene uses a blood or saliva sample to read the DNA sequence and look for changes. This may be done as part of a multigene panel, exome sequencing, or genome sequencing, and the lab classifies any variant using current evidence.
When should I consider getting a genetic test?
There is not yet a broadly established ADGRF5-specific reason for genetic testing in routine care. Testing decisions are usually based on your symptoms, family history, and whether a doctor or genetic counselor thinks a broader test would be more useful.
A genetic result is only one part of your health story
A genetic finding can provide useful insight, although how informative it is varies with the condition and the kind of variant present. Over time, the way the body functions is shaped by many factors, including lifestyle, environment, age, and medical history. In some conditions, especially those influenced by many genes, genetic information offers context rather than certainty and makes the most sense when considered alongside other parts of care. In other situations, a genetic result can give a clear answer. In areas such as medication response, genetic findings may help place individual experiences in context.
Pharmacogenetics
How variants shape your response to medicine
Genetic variation can affect how people respond to medicines. This helps explain why the same treatment works well for one person, seems less helpful for another, or causes more side effects in someone else. In everyday terms, your body may break down, transport, or respond to a drug a little differently based on inherited gene changes, and this can influence both benefit and sensitivity.
What is Pharmacogenetics?
Pharmacogenetics examines how genetic differences affect a person’s response to medications. It studies gene-drug patterns to help explain why the same treatment may work differently from one person to another. For many medicines, genes influence either how strongly a drug works or how the body processes it. This information can support more informed, individualized treatment decisions.

Drugs influenced by the ADGRF5 gene
When should I seek medical advice?
There is not yet a broadly confirmed role for this gene in guiding how medicines are chosen or used. If you have side effects, concerns that a treatment is not working, or questions about your medicines or overall health, talk with your doctor or pharmacist.
