The LGR6 gene helps certain stem cells in the skin, hair follicles, and nails grow, renew tissue, and respond to growth signals. If it does not work properly, tissue repair and normal cell growth may become less well controlled. This gene plays an important role in maintaining skin and related tissues over time. Researchers also study the LGR6 gene because altered activity has been linked to some cancers.
What is a gene?
Genes are sections of DNA that hold instructions your cells use to make molecules or regulate activities in the body. Some carry the code for proteins, which are the parts of cells that do the work. Others mainly help determine when certain processes happen, where they happen, and how strongly they run. Taken together, genes affect how the body develops and functions, and they can influence how you respond to food, stress, or medications.

Overview
LGR6Gene function
What if the gene works
The LGR6 gene helps certain stem cells respond to growth signals. This supports normal renewal of the skin and hair follicles as cells grow, replace themselves, and heal.
Risk
What if the gene does not work
Milder to more severe variants in the LGR6 gene can weaken how cells respond to growth signals called R spondins. This may reduce Wnt signaling, a pathway that helps certain skin and other lining tissue stem cells renew and repair tissue.
Treatment
What does that mean for your treatment
No treatment or drug choice is currently guided by pathogenic or loss-of-function variants in the LGR6 gene in clinical guidelines. The LGR6 gene is being studied mainly as a biomarker and possible drug target in some cancers and tissue repair research, but this has not yet changed routine care.
Gene function
What if the gene works
Your cells use the LGR6 gene to receive and fine tune messages that guide normal growth and renewal. It is part of the signaling network that helps some cells stay ready to refresh tissues over time. Understanding what the LGR6 gene does in normal cell signaling makes it easier to see how your body maintains everyday tissue balance.
The LGR6 gene helps cells detect outside signals at their surface. Its protein can bind R-spondins (signal proteins that strengthen renewal messages), helping cells respond in a more coordinated way.
Through its protein, the LGR6 gene boosts Wnt signaling (a cell communication system that helps control growth and renewal). This helps cells make balanced decisions about dividing, maturing, and maintaining their usual role.
One of its main roles is to help stem cells stay ready to replace older cells. This supports ongoing tissue upkeep in places where cells are regularly renewed, such as the skin and hair follicles.
What is a variant?
A genetic variant is a minor change in a gene’s DNA sequence. 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 have any noticeable effect and simply represent natural genetic variation. Sometimes, 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 LGR6 gene can alter the receptor’s shape, stability, or delivery to the cell surface, which can weaken how cells handle growth-related signals. This is how LGR6 gene variants affect protein function at the molecular level: some changes only partly reduce signaling, while more disruptive variants can leave very little working receptor available. Variants may also disturb binding to partner molecules, making cell communication less efficient.
How variants are linked to conditions
At this stage, the LGR6 gene does not yet have a broadly confirmed link to a specific health condition, so information about LGR6 gene variants linked to health conditions is still evolving. If you have a confirmed change in the LGR6 gene, your doctor or genetic counselor can explain what it may mean for you and your family.
A variant is not necessarily a diagnosis
Genetic variants are common across the general population and are a normal feature of human biology. Most do not directly affect health and instead reflect natural differences among people. For many genes, having a variant associated with a condition points to a possible link, not a definite diagnosis, particularly when several genes and environmental influences play a role. In some situations, though, one well-characterized variant in a particular 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 LGR6 gene. If you have a change in LGR6 on genetic testing or a strong family history of illness, a doctor or genetic counselor can help put that result into context.
Inheritance of LGR6 variants
There is not yet a broadly confirmed Mendelian pattern for how LGR6 gene variants are inherited in relation to a specific, well-established inherited condition. Current evidence does not support a single standard answer for how LGR6 gene variants are inherited in families in the way it does for genes with clearly defined dominant, recessive, or X-linked conditions. The LGR6 gene is located on chromosome 1, which is an autosome, so each person inherits one copy from each parent. This means any inherited LGR6 variant would generally be passed through family lines in the same broad way as other genes on the non-sex chromosomes.
What does my LGR6 result mean for my family?
There isn't yet a broadly confirmed inheritance pattern tied to a specific condition for LGR6, though this understanding can change as research develops. If you have a specific LGR6 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
Genetic testing for variants in the LGR6 gene uses a blood or saliva sample to read your DNA and look for changes in this gene. A lab compares the sequence with a reference and classifies any finding, such as benign, uncertain, or likely disease causing. Results can help clarify whether an LGR6 variant is present.
When should I consider getting a genetic test?
There is not yet a broadly established reason to test the LGR6 gene on its own in routine care. Decisions about genetic testing are usually based on your personal health history, family history, and the findings your doctor or genetic counselor is trying to explain.
A genetic result is only one part of your health story
A genetic result can provide useful insight, but how much it reveals varies by the condition and the kind of variant involved. Lifestyle, environment, age, and medical history, among other factors, also influence how the body functions over time. In some conditions, especially those shaped by many genes, genetic information offers context rather than certainty and is most helpful when viewed together with other parts of care. In other situations, a genetic result can give a clear answer. In areas such as response to medication, 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. 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. Small differences in genes can change how the body breaks down a drug, moves it through the body, or responds to it at its target, which can influence both benefit and sensitivity.
What is Pharmacogenetics?
Pharmacogenetics examines how genetic differences can affect 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 influence both how strongly a drug works and how the body processes it. This information can support treatment decisions that are more informed and more individualized.

Drugs influenced by the LGR6 gene
When should I seek medical advice?
There is not yet a broadly confirmed role for this gene in medication response, so general medicine concerns are best discussed with your doctor. Seek medical advice if you have unexpected side effects, poor symptom control, or questions before starting or changing treatment.
