The LATS2 gene helps control when cells grow, divide, and die, which supports healthy tissue repair. This gene plays an important role in stopping damaged cells from multiplying when they should not. If the gene does not work well, cells may grow out of control, which can contribute to tumors and increase the chance of cancer.
What is a gene?
A gene is a stretch of DNA that carries instructions your cells use to make molecules or regulate processes in the body. Some genes hold the directions for producing proteins, the parts of cells that do much of the work. Other genes mainly guide when, where, and how strongly certain processes take place. Together, genes affect how the body develops and works, and they can influence how you respond to food, stress, or medications. For a more detailed look at this topic, you can read more in LearnHub.
Overview
LATS2Gene function
What if the gene works
The LATS2 gene helps control when cells grow, divide, and die. This supports normal tissue growth and helps keep cells from multiplying when they should not.
Risk
What if the gene does not work
Changes in the LATS2 gene can range from milder to more severe and may partly or strongly weaken signals that control cell growth. When LATS2 activity drops, cells may keep dividing when they should pause or die.
Treatment
What does that mean for your treatment
No treatment or management approach is currently established specifically for pathogenic variants in the LATS2 gene. In cancer research, the LATS2 gene is being studied as part of the Hippo pathway, mainly as a possible biomarker and a potential target for future drugs, but it does not yet guide routine drug choices.
Gene function
What if the gene works
Your cells use the LATS2 gene to keep growth and division in balance. It is part of a control system that helps cells respond to crowding, contact, and other everyday signals. This helps explain how cells know when to stop growing and keep tissues orderly.
LATS2 places a small chemical tag on YAP and TAZ, proteins that can switch growth genes on. This keeps growth signals under tighter control and helps cells slow down when conditions call for restraint.
During cell division, LATS2 helps keep key steps in the right order as one cell becomes two. This supports accurate sharing of cell contents and steady replacement of worn-out cells.
Cells use LATS2 to respond to cues from nearby cells and from the physical pull of their surroundings. This helps control tissue size, cell shape, and the organized layout of many organs.
What is a variant?
A genetic variant is a minor change in the DNA sequence within a gene. These changes are common and help create normal human diversity, including differences 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. In some cases, though, a variant can affect how a gene works more substantially and may contribute to or cause a genetic condition.
Genetic variants
What if the gene does not work
Variants in the LATS2 gene can weaken or silence the protein by changing its shape, shortening it, or lowering how much of it the cell makes. In descriptions of how variants influence the LATS2 gene's function, milder changes may leave partial kinase activity (a chemical signaling function), while more severe variants can cause major loss of activity or make the protein unstable. Some variants also disrupt binding to partner proteins, which can alter cell growth signals.
How variants are linked to conditions
Current evidence on how LATS2 gene variants are linked to conditions is still developing, and the LATS2 gene does not yet have a broadly confirmed link to a specific health condition. If you carry a reported variant in this gene, your doctor or genetic counselor can interpret it in the context of your personal and family history.
A variant is not necessarily a diagnosis
Genetic variants are common across the general population and are a routine part of normal human biology. Most do not directly affect health and simply contribute to natural differences among people. For many genes, having a variant associated with a condition points to a possible link rather than a certain 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 isn't yet broadly confirmed evidence on specific factors that increase or reduce risk specifically related to the LATS2 gene. In most settings, changes involving LATS2 are studied as part of broader cancer biology, where risk is shaped by many genes, age, environment, and chance. Anyone worried about personal cancer risk can talk with a doctor or genetic counselor.
Inheritance of LATS2 variants
There is not yet a broadly confirmed Mendelian inheritance pattern for disease causing variants in the LATS2 gene, so the inheritance of LATS2 gene variants is still being clarified as research develops. LATS2 is located on chromosome 13, which is an autosome, so you inherit one copy of the LATS2 gene from each parent. In general, variants in genes on autosomes can be passed to children of any sex.
What does my LATS2 result mean for my family?
There is not yet a broadly confirmed inherited pattern tied to a specific, well-established condition for LATS2, although this can change as research grows. If you have a LATS2 result and want to understand what it could mean for close relatives, a doctor or genetic counselor can help put that result into the right family context.
Genetic information
Genetic testing
How you find out about variants
If you want to know how genetic testing for LATS2 variants works, a lab usually studies DNA from a blood or saliva sample using panel, exome, or genome sequencing. Results may show a pathogenic variant, a benign variant, or a variant of uncertain significance, which means its health effect is still unclear.
When should I consider getting a genetic test?
There is not yet a broadly established reason for most people to have genetic testing focused specifically on the LATS2 gene. Decisions about testing are usually based on your personal medical history, family history, and the findings from a broader cancer genetics evaluation.
A genetic result is only one part of your health story
A genetic result can provide useful insight, but how much it explains depends on the condition and on the type of variant involved. Over time, many factors, including lifestyle, environment, age, and medical history, influence how the body works. For some conditions, especially those shaped by many genes, genetic information offers context rather than certainty and is best understood together with other parts of care. In other situations, a genetic result may give a clear answer. In areas such as 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. Small differences in DNA 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 medication works well for one person, seems less effective for another, or causes more side effects in someone else. These differences are common and are one reason treatment response can vary from person to person.
What is Pharmacogenetics?
Pharmacogenetics is the area of study that looks at how genetic differences affect the way people respond to medications. It examines connections between genes and drugs to help explain why treatments can work differently from one person to another. For many medicines, genes can influence how strongly a drug works or how the body processes it. This information can help support more informed, individualized treatment decisions.

Drugs influenced by the LATS2 gene
When should I seek medical advice?
There isn't yet a broadly confirmed role for this gene in guiding how medicines are chosen or used, so any concerns about treatment, side effects, or medication changes are best discussed with your doctor or pharmacist.
History
In recent decades, awareness of this gene’s role has grown through cancer genetics research. The LATS2 gene was identified in the late 1990s as a human gene related to the fruit fly warts gene, which had already helped scientists study how growth is controlled. From these first observations, research expanded steadily as LATS2 was recognized as part of the Hippo signaling pathway, a major system involved in tissue growth and cell behavior. Early studies linked altered LATS2 activity to several cancers, which raised interest in how this gene helps keep cell growth in check. Over time, descriptions became more precise as laboratory and tumor studies clarified its place in a wider network of growth regulating genes. These historical steps shaped today’s understanding of LATS2 in human disease research.
