Your cells use the LRRC31 gene to make a protein that helps control cell signals linked to growth and normal tissue function. If this gene does not work normally, those signals may become less balanced, which can affect how cells develop and how they respond to their surroundings. Changes in the LRRC31 gene are mainly discussed in research settings rather than everyday health conversations.
What is a gene?
Genes are stretches of DNA that carry instructions your cells use to make molecules or direct processes in the body. Some genes hold the information needed to produce proteins, the parts of cells that do much of the work. Others mainly regulate when certain processes take place, where they occur, and how strongly they run. Together, genes affect how the body develops and works, and they can influence how you respond to food, stress, or medications. For a deeper look at this topic, you can find more in the LearnHub.
Overview
LRRC31Gene function
What if the gene works
The LRRC31 gene makes a protein that helps with cell signaling. It is active in placental tissue, where it supports normal placental cell development and function.
Risk
What if the gene does not work
Changes in the LRRC31 gene can alter the LRRC31 protein’s leucine-rich repeat structure, which may weaken how it folds and interacts with other proteins. Milder variants may leave some activity intact, while more severe variants can reduce function further.
Treatment
What does that mean for your treatment
No LRRC31-specific treatment or drug selection approach is currently established in clinical guidelines. Care is based on the person’s symptoms and overall diagnosis rather than a pathogenic variant in the LRRC31 gene itself.
Gene function
What if the gene works
Your cells use the LRRC31 gene to make a protein with repeated parts that often act as contact points between proteins. This helps explain what the LRRC31 gene does in the body: it supports organized communication inside cells. When it is working as expected, cells can coordinate routine jobs in a steady way.
The LRRC31 protein has repeated parts that help proteins connect with each other. These connections support small protein teams that carry out routine work inside cells.
By helping proteins gather in the right place, LRRC31 supports how cells pass messages internally. This kind of signaling helps keep normal cell activity coordinated.
What is a variant?
A genetic variant is a minor change in the DNA sequence within a gene. These changes are common and help explain normal human diversity, including differences in appearance, metabolism, or how the body responds to environmental influences. Many variants do not lead to any noticeable effect and simply represent natural genetic variation. In some cases, though, a variant can affect how a gene functions more strongly and may contribute to or cause a genetic condition.
Genetic variants
What if the gene does not work
Variants in the LRRC31 gene can alter the protein’s shape, which may reduce its stability or weaken how it connects with other proteins inside the cell. How variants in the LRRC31 gene affect protein function often depends on the type of DNA change. Some variants may cause only a partial drop in activity, while more disruptive variants can shorten the protein or greatly reduce how much of it the cell makes.
How variants are linked to conditions
Variants in the LRRC31 gene do not yet have a broadly confirmed link to a specific health condition, though research on conditions linked to LRRC31 gene variants is still developing. People with a confirmed LRRC31 variant should rely on guidance from their doctor or genetic counselor for interpretation of their own results.
A variant is not necessarily a diagnosis
Genetic variants are a normal part of being human and are common across the general population. Most have no direct effect on health and simply reflect natural human diversity. For many genes, carrying a variant associated with a condition points to a possible link rather than a definite diagnosis, especially when more than one gene 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 LRRC31 gene. If testing has found a change in LRRC31, a doctor or genetic counselor can help explain what it may mean in the context of your personal and family history.
Inheritance of LRRC31 variants
There is not yet a broadly confirmed LRRC31 inheritance pattern tied to a specific human condition, so how LRRC31 variants are inherited in a disease setting is still being clarified. LRRC31 is located on an autosome, which means you inherit one copy of the LRRC31 gene from each parent. In general, changes in autosomal genes can be passed to children of any sex.
What does my LRRC31 result mean for my family?
There is not yet a broadly confirmed inherited condition linked to the LRRC31 gene in the way there is for some better-studied genes. If you have a specific LRRC31 result and want to understand what it could mean for close relatives, a doctor or genetic counselor can explain it in the context of your family history and the exact change found.
Genetic information
Genetic testing
How you find out about variants
To find out whether you carry a variant in the LRRC31 gene, doctors use genetic testing for LRRC31 variants on a blood or saliva sample. A lab reads the DNA sequence and compares it with the usual version of the gene. The report lists any variants found and explains whether they are known, likely harmless, or need more interpretation.
When should I consider getting a genetic test?
There is not yet a broadly established, LRRC31-specific reason for genetic testing in routine care. Testing decisions are usually based on your personal health history and family history and are best discussed with a doctor or genetic counselor.
A genetic result is only one part of your health story
A genetic finding can be informative, but how much it reveals varies by the condition and the kind of variant involved. Many factors, including lifestyle, environment, age, and medical history, influence how the body functions over time. For some conditions, especially those shaped by many genes, genetic information provides context rather than certainty and is most useful when viewed alongside other parts of care. In other situations, a genetic result can give a clear answer. In areas like 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. One person may break down a drug more slowly or more quickly than another, which can change how much of the medicine reaches the body and how long it stays active. These common differences can influence how well a treatment works or how likely someone is to notice side effects.
What is Pharmacogenetics?
Pharmacogenetics examines how genetic differences shape a person’s response to medications. It studies links between genes and drugs to help explain why the same treatment may work differently in different people. For many medicines, genes affect both how the body processes a drug and how strong its effects are. This information can support more personalized and better informed treatment decisions. You can explore this topic further in the LearnHub.
Drugs influenced by the LRRC31 gene
When should I seek medical advice?
There is not yet a broadly confirmed role for this gene in how medicines work, so medication side effects, a treatment that is not working as expected, or other health concerns are best discussed with your doctor.
