The GPR83 gene helps certain cells receive and pass along signals, especially in the brain and in some immune cells. This gene plays an important role in how your body helps regulate appetite, energy balance, stress responses, and immune activity. If the GPR83 gene does not work as expected, these signals may become less well controlled, which can influence body weight, how the body responds to stress, and immune balance.
What is a gene?
Genes are sections of DNA that carry instructions your cells use to make molecules or manage processes throughout the body. In some cases, those instructions are used to produce proteins, which are the parts of cells that do the work. Other genes are mainly involved in controlling when certain processes happen, where they happen, and how active they are. Taken together, genes affect how the body grows and works, and they can also influence how you respond to food, stress, and medications. More detail on this topic is available in the LearnHub.
Overview
GPR83Gene function
What if the gene works
The GPR83 gene makes a cell surface receptor that helps cells respond to chemical signals. It is active in parts of the brain and immune system and may support appetite, stress responses, and immune cell activity.
Risk
What if the gene does not work
Milder to more severe variants in the GPR83 gene can reduce how well its receptor is made, reaches the cell surface, or passes signals inside cells. This can alter cell communication, especially in brain and immune tissues.
Treatment
What does that mean for your treatment
A pathogenic or loss-of-function variant in the GPR83 gene does not currently change standard treatment or drug choices, because no GPR83-specific treatment or management approach is established. The GPR83 gene is being studied as a possible drug target and biomarker in brain signaling, metabolism, immune regulation, and some cancers, but this has not yet led to guideline-based care.
Gene function
What if the gene works
The normal function of the GPR83 gene is to help certain brain and immune cells receive outside signals. Its protein sits at the cell surface as a receptor, a signal catching protein, and passes messages inward so cells can respond in a controlled way. This supports everyday communication in nerve networks and helps immune cells stay coordinated.
The GPR83 gene provides instructions for a cell surface receptor that detects chemical messages outside the cell. When that receptor is activated, it relays the message inward so the cell can adjust its activity.
In the brain, this receptor helps nerve cells fine tune how they respond to incoming signals. This supports steady communication in circuits linked to appetite, stress responses, and daily body rhythms.
GPR83 is active in some immune cells, including regulatory T cells that help keep immune reactions balanced. Its signaling helps these cells communicate and maintain controlled immune activity.
What is a variant?
Within a gene, a genetic variant is a small difference in the DNA sequence. Variants are common and help explain normal human diversity, such as differences in appearance, metabolism, and the body’s response to environmental influences. Many do not produce any noticeable effect and simply represent natural genetic variation. In some situations, though, a variant changes gene function more significantly and may contribute to or cause a genetic condition.
Genetic variants
What if the gene does not work
Variants in the GPR83 gene can change the receptor's shape, stability, or movement to the cell surface, which may alter how GPR83 gene variants affect cell signaling. Milder changes may slightly reduce signaling or weaken interactions with partner proteins. More disruptive variants can cause poor folding, faster breakdown, or little to no receptor activity in the cell.
How variants are linked to conditions
Variants in the GPR83 gene do not yet have a broadly confirmed link to a specific health condition, and research on how GPR83 gene variants may relate to disease risk is still developing. Anyone with a confirmed GPR83-related finding should rely on guidance from their doctor or genetic counselor rather than general information.
A variant is not necessarily a diagnosis
Genetic variants are a usual feature of human biology and are widespread across the general population. Most do not directly affect health and simply reflect normal human variation. For many genes, having a variant associated with a condition suggests a possible link rather than a confirmed diagnosis, especially when several genes and environmental influences play a role. Still, in certain situations, one well-characterized variant in a particular gene can be 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 GPR83 gene. If a test shows a change in GPR83, its meaning often depends on the exact change and the rest of your health and family history.
Inheritance of GPR83 variants
There is not yet a broadly confirmed inheritance pattern tied to a specific GPR83-related condition. The GPR83 gene is located on the X chromosome, so how GPR83 gene variants are inherited can differ between sons and daughters, since males usually have one X chromosome and females usually have two.
What does my GPR83 result mean for my family?
There isn’t yet a broadly confirmed inheritance pattern tied to a specific health condition for GPR83, though this can change as research moves forward. If you have a specific GPR83 result and want to understand what it may mean for close relatives, a doctor or genetic counselor can help explain it in the context of your family history.
Genetic information
Genetic testing
How you find out about variants
Genetic testing for variants in the GPR83 gene usually analyzes DNA from a blood or saliva sample using sequencing, which reads the gene's code letter by letter. The lab compares your result with a reference sequence and classifies any variant based on current medical evidence.
When should I consider getting a genetic test?
There is not yet a broadly established, GPR83-specific reason for genetic testing in routine care. Decisions about testing are usually based on your personal health history, symptoms, and family history, ideally with guidance from a doctor or genetic counselor.
A genetic result is only one part of your health story
Genetic results can be informative, although how much they clarify depends on the condition and the kind of variant involved. Over time, how the body works is also shaped by many other factors, including lifestyle, environment, age, and medical history. In some conditions, especially those influenced by many genes, genetic information provides context rather than certainty and is best understood together with other parts of care. In other situations, a genetic result may offer a clear answer. In areas like medication response, these 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 faster or slower than others, while some are more or less sensitive to its effects. This helps explain why the same treatment may work well for one person, seem weaker in another, or cause more side effects in someone else. These differences are common and are one part of why medication response varies from person to person.
What is Pharmacogenetics?
Pharmacogenetics examines how differences in genes can shape the way a person responds to medications. It studies links 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 choices that are more informed and more individualized.

Drugs influenced by the GPR83 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, so questions about side effects, new symptoms, or changes in how a treatment feels are best discussed with your doctor.
History
The GPR83 gene entered the scientific literature in the late 1980s and early 1990s, during a period when many cell signaling genes were being identified. It was first recognized as a member of the large family of G protein coupled receptors, a group that drew strong research interest because of its importance in human biology and medicine. Early studies described it with different names before GPR83 became the standard label. From these first observations, research expanded steadily as scientists mapped where the gene is active in the body and explored its links to immune and brain related pathways. Over time, descriptions became more precise as genetic and laboratory methods improved. The way this gene was viewed has shifted over time, moving from a newly cataloged receptor gene to one with a clearer place in modern genetics research.
