The LRRC37B gene makes a protein with leucine rich repeats, a structure that usually helps proteins connect and communicate inside cells. If this gene does not work as expected, those cell to cell protein interactions may be altered. LRRC37B is mainly studied as part of a complex region on chromosome 17 that contains several genes important in brain and body development. It is not a gene that has become widely known in everyday culture or celebrity health stories.
What is a gene?
Genes are sections of DNA that carry instructions your cells use to make molecules or regulate processes in the body. Some genes provide the directions for making proteins, the parts of cells that do much of the work. Other genes mainly control when certain processes happen, where they occur, and how strongly they operate. Together, genes affect how the body develops and functions, and they can also shape how you respond to food, stress, or medications. For a more detailed look at this topic, you can find more in the LearnHub.
Overview
LRRC37BGene function
What if the gene works
The LRRC37B gene makes a protein with repeat segments that often help proteins connect with other proteins. This suggests it supports routine cell signaling and communication.
Risk
What if the gene does not work
Changes in the LRRC37B gene may alter how much LRRC37B protein cells make or how well it works. Milder variants may have little effect, while more severe variants can disrupt its normal cellular role more strongly.
Treatment
What does that mean for your treatment
For pathogenic or loss-of-function variants in the LRRC37B gene, no LRRC37B-specific treatment or drug-selection approach is currently established in clinical guidelines.
Gene function
What if the gene works
Your cells use the LRRC37B gene to help proteins connect with each other in an organized way. Its protein contains leucine rich repeat sections, which are common structures used for protein contact. Understanding how the LRRC37B gene works helps explain how cells keep signaling coordinated during everyday activity.
The LRRC37B gene helps cells make a protein that binds other proteins. Its leucine rich repeat sections create contact surfaces that help these connections happen in an orderly way.
By helping proteins gather and interact, this protein supports routine cell signaling at the cell surface and inside the cell. That coordination helps everyday messages move through cells in a controlled way.
What is a variant?
A genetic variant is a small difference in the DNA sequence of a gene. These differences are common and help make up normal human diversity, such as variation in appearance, metabolism, or the way the body responds to environmental influences. Many variants do not have any noticeable effect and simply represent natural genetic variation. Sometimes, however, a variant can change gene function more substantially and may contribute to or cause a genetic condition.
Genetic variants
What if the gene does not work
How LRRC37B gene variants affect protein function depends on the type of DNA change. Some variants slightly change the protein’s shape or stability, which may weaken how it interacts with other cell proteins, while more disruptive variants can create a shortened protein or greatly reduce how much protein the cell makes. This range from milder to more severe variants can lead to partial loss of function or, in some cases, little to no functional protein.
How variants are linked to conditions
The LRRC37B gene does not yet have a broadly confirmed link to a specific health condition, and research on LRRC37B gene variants and health conditions is still developing. Anyone with a confirmed variant in the LRRC37B gene should rely on guidance from their doctor or genetic counselor to understand what it may mean for them.
A variant is not necessarily a diagnosis
Variants in genes are a normal and common part of human biology. Most do not directly affect health and simply reflect natural variation among people. For many genes, having a variant associated with a condition points to a possible link, not a definite diagnosis, especially when several genes and environmental influences also play a role. In some situations, though, one 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 LRRC37B gene. If LRRC37B appears on a genetic test, its meaning usually depends on the exact change found and the rest of your personal and family health picture.
Inheritance of LRRC37B variants
There is not yet a broadly confirmed disease-specific inheritance pattern for LRRC37B gene variants. Current human genetics evidence has not established LRRC37B gene inheritance as a clearly defined autosomal dominant, autosomal recessive, or X linked condition. The LRRC37B gene is located on chromosome 17, which is an autosome, so you inherit one copy from your mother and one copy from your father. In general, that means either parent can pass an LRRC37B variant to a child.
What does my LRRC37B result mean for my family?
There is not yet a broadly confirmed inheritance pattern tied to a specific health condition for LRRC37B, although this can change as research develops. If you have a specific LRRC37B result and want to understand what it could mean for relatives, a doctor or genetic counselor can help explain it in the context of your family history and the exact result.
Genetic information
Genetic testing
How you find out about variants
Variants in the LRRC37B gene are usually found through genetic testing, most often in a multigene panel, exome sequencing, or genome sequencing using a blood or saliva sample. In practice, genetic testing for LRRC37B variants reads the DNA code and compares it with a reference sequence to look for changes a lab can classify.
When should I consider getting a genetic test?
There is not yet a broadly established, LRRC37B-specific clinical reason for testing. Decisions about genetic testing are usually made with a doctor or genetic counselor, based on personal symptoms, family history, and whether a broader genetic test may be more useful.
A genetic result is only one part of your health story
A genetic result can provide valuable insight, but how much it reveals depends on the condition and the kind of variant involved. Lifestyle, environment, age, and medical history are among the many factors that shape how the body functions over time. For some conditions, especially those influenced by many genes, genetic information provides context rather than certainty and is most useful when considered alongside 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 variation can affect how people respond to medicines. Small differences in genes can change how the body breaks down a drug, moves it through the bloodstream, or responds at the drug’s target. This helps explain why the same treatment works well for one person, seems weaker for another, or causes more side effects in someone else. These differences are common and are one part of why medication response can vary from person to person.
What is Pharmacogenetics?
Pharmacogenetics examines how genetic differences shape a person’s response to medications. It studies connections between genes and drugs to help explain why the same treatment may work differently from one person to another. For many medicines, genes can affect 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 LRRC37B gene
When should I seek medical advice?
There is not yet a broadly confirmed role for this gene in how people respond to medicines, so questions about symptoms, side effects, or treatment choices are best discussed with your doctor.
