The GPR87 gene gives cells instructions for a receptor on their surface that helps them respond to growth and stress signals. This gene plays an important role in how certain tissues, especially the lining of the mouth, lungs, and skin, balance cell survival and repair. If it does not work normally or becomes too active, cells may survive longer than they should, which can support tumor growth. GPR87 is mainly known in cancer research rather than in everyday public discussion.
What is a gene?
Genes are sections of DNA that carry instructions your cells use to make molecules or regulate activities in the body. Some genes hold the code for proteins, the parts of cells that do the work. Other genes mainly control when certain processes happen, where they happen, and how strongly they run. Together, genes affect how the body develops and functions, and they can also shape how you respond to food, stress, or medications.

Overview
GPR87Gene function
What if the gene works
The GPR87 gene helps make a cell surface receptor that passes signals inward. This signaling can support normal cell growth and cell survival.
Risk
What if the gene does not work
When the GPR87 gene works less well, cell surface signaling through this receptor can weaken. Milder to more severe variants may reduce how strongly cells respond to outside chemical cues, especially signals linked to cell survival and stress responses.
Treatment
What does that mean for your treatment
No treatment or drug choice approach linked specifically to a pathogenic or loss-of-function variant in the GPR87 gene is currently established in clinical guidelines. The GPR87 gene is being studied mainly in cancer research as a possible biomarker and drug target, but this has not yet changed routine care.
Gene function
What if the gene works
Your cells constantly read signals from the space around them. The GPR87 gene helps with this by providing instructions for a receptor on the cell surface that passes messages inward. Understanding what the GPR87 gene does helps explain how cells adjust everyday activity to their surroundings.
GPR87 makes a receptor that sits in the cell membrane and detects chemical cues outside the cell. When these cues arrive, it starts an internal message that tells the cell how to respond.
After activation, this receptor works through G proteins (inside-cell signal carriers). This helps turn an outside cue into changes in cell activity in a controlled way.
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 more substantially change how a gene functions and may contribute to or cause a genetic condition.
Genetic variants
What if the gene does not work
Variants in the GPR87 gene can change the receptor’s shape, how well it reaches the cell surface, or how strongly it sends signals inside the cell. Milder variants may only partly reduce protein stability or signaling, while more severe variants can shorten the protein or keep it from taking the right shape, leaving little or no activity. This range helps explain how variants in the GPR87 gene affect cell signaling at different levels in different cells.
How variants are linked to conditions
Variants in the GPR87 gene do not yet have a broadly confirmed link to a specific health condition, although research on links between GPR87 gene variants and disease is still developing. If you have a reported change in the GPR87 gene, your care team or genetic counselor can explain what that result may mean in the context of your personal and family history.
A variant is not necessarily a diagnosis
Genetic variants are a routine part of human biology and are widely seen across the general population. Most do not have a direct effect on health and simply represent 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 also play a role. 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 is not yet broadly confirmed evidence on specific factors that increase or reduce health risk related to the GPR87 gene. If you have a change in GPR87 on genetic testing or a strong family history of illness, a doctor or genetic counselor can help put that result into context.
Inheritance of GPR87 variants
For families looking into how GPR87 gene variants are inherited, there is not yet a broadly confirmed disease-specific inheritance pattern linked to the GPR87 gene. Research on this gene is still developing, so inheritance information may become clearer over time. The GPR87 gene is located on chromosome 3, which is an autosome. That means you inherit one copy of the GPR87 gene from your mother and one copy from your father.
What does my GPR87 result mean for my family?
There is not yet a broadly confirmed family inheritance pattern tied to a specific health condition for GPR87, though this can change as research grows. If you have a specific GPR87 result and want to understand what it could mean for relatives, 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
To find out whether you carry a variant in the GPR87 gene, genetic testing for GPR87 variants analyzes DNA from a blood sample, cheek swab, or saliva sample. A lab reads the gene’s sequence and compares it with a reference sequence to identify changes and classify whether a variant is known, likely harmless, or needs more study.
When should I consider getting a genetic test?
There is not yet a broadly established reason to get genetic testing just for the GPR87 gene. Decisions about testing are usually based on your personal health history and family history, together with a doctor or genetic counselor.
A genetic result is only one part of your health story
Genetic test results can provide useful insight, but what they can tell you varies with the condition and the kind of variant involved. Over time, many factors, including lifestyle, environment, age, and medical history, also influence how the body functions. For some conditions, especially those shaped by many genes, genetic information offers context rather than certainty and makes the most sense when viewed alongside other parts of care. In other situations, a genetic result can give a clear answer. In areas like medication response, these results can help put personal experiences into perspective.
Pharmacogenetics
How variants shape your response to medicine
Genetic variation can affect how your body handles certain medicines, so the same treatment may not work the same way for everyone. These inherited differences can change how quickly a drug is broken down, how strongly it acts in the body, or how likely side effects are. This kind of variation is common and helps explain why one person gets good benefit from a medicine while another may notice less effect or more sensitivity.
What is Pharmacogenetics?
Pharmacogenetics examines how genetic differences can affect the way a person responds to medication. It looks at links between genes and drugs 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 handles it. This information can support treatment decisions that are more informed and more individualized. More detail on this topic is available in the LearnHub.
Drugs influenced by the GPR87 gene
When should I seek medical advice?
There is not yet a widely confirmed role for this gene in guiding medication choices, so general questions about medicines, side effects, or treatment response are best discussed with your doctor. Seek medical advice if a medicine is causing problems, does not seem to be helping, or you have concerns about how it fits with your overall health.
History
GPR87 entered the scientific literature in the early 2000s, when researchers were cataloging many newly identified cell surface signaling genes. Initially understood only through sequence data, later recognized as tied to a specific gene family, it was grouped with the large family of G protein coupled receptors. From these first observations, research expanded steadily. Later studies drew more attention to GPR87 after reports linked higher activity of this gene to several cancers, especially squamous cell cancers. Its history is mainly a research story rather than a public one, shaped by the broader effort to map signaling genes and understand how they may influence cell growth and survival.
