The LHFPL6 gene helps make a protein in the cell membrane that supports normal cell signaling and growth. If this gene does not work as expected, growth in fatty tissue may become less controlled. Changes affecting the LHFPL6 gene have been linked to lipomas, which are noncancerous fatty lumps under the skin, and some people first learn about this gene during testing for these growths.
What is a gene?
A gene is a stretch of DNA that holds instructions your cells use to make molecules or regulate processes in the body. Some genes provide the instructions for producing proteins, which are the working parts of cells. Others mainly help direct 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 influence how you respond to food, stress, or medications. For a deeper look at this topic, you can find more in the LearnHub.
Overview
LHFPL6Gene function
What if the gene works
The LHFPL6 gene helps make a protein in the cell membrane. It may help cells communicate and control growth at the cell surface.
Risk
What if the gene does not work
Changes in the LHFPL6 gene may alter how much LHFPL6 protein a cell makes or how well it works at the cell membrane. Milder variants may have small effects, while more severe variants can disrupt the protein more clearly.
Treatment
What does that mean for your treatment
For a pathogenic or loss-of-function variant in the LHFPL6 gene, no treatment or management approach specific to this gene is currently established. The LHFPL6 gene is being studied mainly as a possible biomarker in some tumors, including certain lipomas, rather than as a target that currently guides drug choice.
Gene function
What if the gene works
Your cells use the LHFPL6 gene to make a membrane protein that helps organize activity at the cell surface. Many routine cell tasks depend on proteins being in the right place in that outer layer. Understanding how the LHFPL6 gene works gives a clearer picture of how cells keep their surface organized.
The LHFPL6 gene makes a protein that sits in the cell membrane and crosses it four times. This setup helps organize activity at the cell surface during routine cell function.
In healthy cells, this membrane protein helps keep other surface proteins arranged in a steady way. That orderly layout supports everyday communication between the cell and its surroundings.
What is a variant?
A genetic variant is a small difference in the DNA sequence of a gene. These differences are common and are part of normal human diversity, including variation in appearance, metabolism, or how 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 how a gene functions more strongly and may contribute to or cause a genetic condition.
Genetic variants
What if the gene does not work
Changes in the LHFPL6 gene can affect protein function by altering the protein’s shape, stability, or placement in the cell membrane. Some missense variants may have milder effects and only partly weaken folding or interactions with partner proteins. More disruptive splice, frameshift, or stop-gain variants can sharply reduce protein production or leave little to no working protein.
How variants are linked to conditions
Current evidence on how LHFPL6 gene variants are linked to conditions is still developing. The LHFPL6 gene does not yet have a broadly confirmed link to a specific inherited health condition, and anyone with a confirmed LHFPL6-related finding should rely on advice from their doctor or genetic counselor for personal interpretation.
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 have a direct effect on health and simply reflect natural variation among people. For many genes, having a variant associated with a condition points to a possible link rather than a certain diagnosis, particularly when more than one gene and environmental factors also 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 isn't yet broadly confirmed evidence on specific factors that increase or reduce health risk related to the LHFPL6 gene. Anyone with concerns about personal or family risk can speak with a doctor or genetic counselor.
Inheritance of LHFPL6 variants
Information on how variants of the LHFPL6 gene are inherited is still developing. There is not yet a broadly confirmed Mendelian inheritance pattern for a specific LHFPL6 related condition. The LHFPL6 gene is located on chromosome 13, which is an autosome, so each person inherits one copy from each parent. This means any inherited LHFPL6 variant would be passed through the usual autosomal pattern, but a specific dominant or recessive disease pattern has not been firmly established.
What does my LHFPL6 result mean for my family?
There is not yet a broadly confirmed inherited pattern tied to a specific health condition for LHFPL6, so a result in this gene usually does not have a clear, established meaning for family members on its own. If you have a specific LHFPL6 result and want to know whether relatives could also be affected or carry it, a doctor or genetic counselor can explain what it may mean in your family.
Genetic information
Genetic testing
How you find out about variants
Genetic testing is the main way to find out about LHFPL6 variants. A lab studies DNA from a blood or saliva sample, usually by sequencing the LHFPL6 gene and sometimes checking for larger missing or extra pieces. The report lists any variant found and explains whether its health meaning is known, uncertain, or not linked to disease.
When should I consider getting a genetic test?
There is not yet a broadly established reason to order genetic testing just for the LHFPL6 gene. Testing decisions are usually based on your own health history, family history, and the broader question your doctor or genetic counselor is trying to answer.
A genetic result is only one part of your health story
Genetic findings can provide useful insight, but the amount they reveal varies with the condition and the kind of variant involved. How your body functions over time is also shaped by many factors, including lifestyle, environment, age, and medical history. For some conditions, particularly those affected by many genes, genetic information offers context rather than certainty and is most useful when considered with 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 personal experiences in 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 body, or responds to it at its target. This helps explain why the same treatment works well for one person, seems weaker in another, or causes more side effects in someone else.
What is Pharmacogenetics?
Pharmacogenetics examines how differences in genes affect the way people respond to medications. It studies gene and drug patterns to better explain why the same treatment may work differently from one person to another. For many medicines, genes help shape how strongly a drug works or how the body handles it. This information can support more informed, more personalized treatment decisions.

Drugs influenced by the LHFPL6 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 any concerns about side effects, new symptoms, or how well a treatment is working are best discussed with your doctor.
