The LRRC14 gene gives your body instructions for making a protein that helps cells connect with other proteins and pass signals. This gene plays an important role in the signaling networks cells use to stay organized and respond to their environment. If it does not work as expected, cell communication may be disrupted, which can affect how cells function.
What is a gene?
Genes are sections of DNA that give your cells instructions for making molecules or for managing processes in the body. Some genes carry the information needed to make proteins, the parts of cells that do much of the work. Other genes mainly help determine when certain processes happen, where they happen, and how strongly they are active. Taken together, genes affect how the body develops and functions, and they can influence how you respond to food, stress, or medications. You can find more on this topic in the LearnHub.
Overview
LRRC14Gene function
What if the gene works
The LRRC14 gene gives cells instructions for making a leucine rich repeat protein. That kind of protein usually helps cells connect with other proteins during routine cell activity.
Risk
What if the gene does not work
Variants in the LRRC14 gene can range from milder to more severe and may partly or fully reduce the LRRC14 protein’s function. This can disrupt its usual interactions with other proteins inside cells.
Treatment
What does that mean for your treatment
For pathogenic or loss-of-function variants in the LRRC14 gene, no LRRC14-specific treatment or management approach is currently established. Care is guided by the person’s symptoms and overall diagnosis rather than by LRRC14-directed drug choices.
Gene function
What if the gene works
Inside your cells, the LRRC14 gene supports routine protein teamwork. It makes a protein with repeat sections that are built to connect with other proteins. Understanding how the LRRC14 gene works in cells helps explain its steady role in day to day cell activity.
The LRRC14 gene makes a protein with repeat sections that help proteins attach to one another. These contacts support the organized partnerships cells use for routine internal work.
What is a variant?
A genetic variant is a minor difference in the DNA sequence within a gene. These differences are common and help shape normal human diversity, including variations in appearance, metabolism, and the way the body reacts to environmental influences. Many variants do not have any noticeable effect and are simply part of natural genetic variation. At times, though, a variant can change how a gene works more significantly and may contribute to or lead to a genetic condition.
Genetic variants
What if the gene does not work
In the LRRC14 gene, variants can change the protein's shape, stability, or ability to interact with other cell proteins, which is how LRRC14 gene variants affect protein function. Milder variants may only partly alter these interactions. More disruptive variants can shorten the protein or sharply lower how much of it is made, leading to a stronger loss of function.
How variants are linked to conditions
Current evidence on LRRC14 gene variants linked to disease is still developing, and the LRRC14 gene does not yet have a broadly confirmed link to a specific health condition. Anyone with a confirmed LRRC14-related diagnosis 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 routine feature of human biology and occur widely across the population. Most do not directly affect health and instead reflect normal human variation. For many genes, having a variant associated with a condition points to a possible link rather than a definitive diagnosis, especially when several genes and environmental influences are involved. Still, in some situations, 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 LRRC14 gene. If LRRC14 appears on a genetic test report, a doctor or genetic counselor can explain what it may mean in the context of your personal and family history.
Inheritance of LRRC14 variants
There is not yet a broadly confirmed, disease-specific inheritance pattern for LRRC14, so the inheritance of LRRC14 gene variants is still being clarified as research develops. The LRRC14 gene is located on an autosome rather than a sex chromosome, which means you inherit one copy from each parent. Because of that, any future health links would not be expected to follow an X-linked or Y-linked pattern.
What does my LRRC14 result mean for my family?
There is not yet a broadly confirmed inheritance pattern tied to a specific health condition for LRRC14, and this picture may become clearer as research grows. If you have a specific LRRC14 result, the meaning for relatives depends on exactly what was found and why the test was done.
Genetic information
Genetic testing
How you find out about variants
Genetic testing for variants in the LRRC14 gene uses a blood sample, saliva sample, or cheek swab to read your DNA. A lab compares the LRRC14 gene sequence with a reference sequence and reports whether a variant is found, often describing it as benign, uncertain, or clinically significant based on current evidence.
When should I consider getting a genetic test?
There is not yet a broadly established, LRRC14-specific reason for genetic testing in routine care. Decisions about testing are usually best made with a doctor or genetic counselor, based on your symptoms, other test results, and family history.
A genetic result is only one part of your health story
A genetic finding can provide useful insight, but how much it reveals depends on the condition and the kind of variant involved. Over time, many factors, including lifestyle, environment, age, and medical history, affect how the body works. For some conditions, especially those shaped 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, genetic results can help put individual experiences into context.
Pharmacogenetics
How variants shape your response to medicine
Genetic differences can affect how a person responds to medicines. They can change how quickly the body breaks down a drug, how much of it reaches the bloodstream, or how strongly the body reacts to it. That helps explain why the same treatment works well for one person, has less effect in another, or causes more side effects in someone else.
What is Pharmacogenetics?
Pharmacogenetics examines how differences in genes can shape the way someone responds to a medication. It studies gene drug relationships to help explain why the same treatment may not work in the same way for every person. With many medicines, genes can affect how powerful a drug’s effects are or how the body handles it. This information can support treatment choices that are both better informed and more individualized. More detail on this topic is available in the LearnHub.
Drugs influenced by the LRRC14 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. For questions about side effects, a medicine not working as expected, or how your health history may affect treatment, speak with your doctor or pharmacist.
