The YES1 gene gives cells instructions for a signaling protein that helps control growth, movement, and survival. If it does not work normally, especially if it becomes too active, cells may keep growing when they should slow down, which can contribute to some cancers. In medicine, this gene is important because it can affect how certain tumors behave and whether they may respond to targeted treatment.
What is a gene?
A gene is a piece of DNA that carries instructions your cells use to make molecules or direct processes in the body. Some genes hold the code for building proteins, which do much of the cell’s work. Other genes mainly control when certain processes happen, where they occur, and how active they are. Together, genes affect how the body develops and functions, and they can influence how you respond to food, stress, or medications.

Overview
YES1Gene function
What if the gene works
The YES1 gene helps cells send signals that guide growth, survival, movement, and attachment to nearby cells. Its protein acts like an internal switch, helping tissues grow and repair in a controlled way.
Risk
What if the gene does not work
Milder to more severe variants in the YES1 gene can change how strongly cells receive growth signals. When its activity is too low or too high, signaling that helps control cell growth, movement, and survival becomes less balanced.
Treatment
What does that mean for your treatment
No YES1-specific treatment or management approach is currently established for pathogenic or loss-of-function variants in the YES1 gene. In cancer research, altered YES1 activity is being studied as a possible drug target and biomarker, including for response or resistance to some kinase inhibitors.
Gene function
What if the gene works
Your cells use the YES1 gene to pass signals from the cell surface to the inside of the cell. These signals help coordinate everyday tasks like growth, attachment, and movement. Understanding what the YES1 gene does in the body helps explain how cells respond in an orderly way to their surroundings.
The YES1 gene helps make a signaling protein that carries messages from the cell surface inward. Its protein is a kinase (a protein that adds a small chemical tag to other proteins), which helps turn important cell signals on at the right moment.
These signals help cells manage normal growth and division. In healthy tissue, this supports steady cell turnover and a balanced response to growth cues.
The protein made from the YES1 gene helps cells respond to contact with nearby cells and the material around them. This supports stable cell attachment and helps tissues keep their usual structure.
The protein from the YES1 gene also helps organize the cell’s internal scaffold, which lets cells change shape in a controlled way. This supports normal cell movement during routine tissue renewal.
What is a variant?
A genetic variant is a small difference in the DNA sequence of a gene. These changes are common and help shape normal human diversity, such as differences in appearance, metabolism, or the way the body responds to environmental influences. Many variants have no noticeable effect and are simply part of natural genetic variation. Sometimes, however, a variant can change how a gene functions more substantially and may contribute to or cause a genetic condition.
Genetic variants
What if the gene does not work
Variants in the YES1 gene can change the shape or amount of its protein, which may weaken it or leave cell signaling too active. In practice, how YES1 gene variants affect cell signaling depends on the change: some only slightly alter protein stability or its ability to connect with other proteins, while more disruptive variants can greatly reduce activity or keep signaling switched on.
How variants are linked to conditions
The YES1 gene does not yet have a broadly confirmed link to a specific inherited health condition, although research on conditions linked to YES1 gene variants is still developing. Anyone with a confirmed YES1 variant can use guidance from their doctor or genetic counselor to understand what that result may mean for their own health and family.
A variant is not necessarily a diagnosis
Genetic variants are a routine part of human biology and are widely found in the general population. Most do not directly affect health and instead reflect normal human diversity. For many genes, having a variant associated with a condition points to a possible link rather than a certain diagnosis, especially when several genes and environmental factors 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 YES1 gene. If a YES1 change is found on testing, its meaning depends on the exact change and the health condition being looked at, so a doctor or genetic counselor can explain personal risk.
Inheritance of YES1 variants
There is not yet a broadly confirmed Mendelian inheritance pattern tied to a specific inherited condition for the YES1 gene, so how YES1 gene variants are inherited in health conditions is still being clarified. Current knowledge does not support describing the YES1 gene as having one well-established dominant, recessive, or X-linked pattern for a defined genetic syndrome. The YES1 gene is located on chromosome 18, which is an autosome, so you inherit one copy from each parent.
What does my YES1 result mean for my family?
There is not yet a broadly confirmed inheritance pattern tied to a specific, well-established inherited condition for the YES1 gene, and understanding may change as research develops. If you have a specific YES1 result and want to know what it could mean for close relatives, a doctor or genetic counselor can help interpret it in the context of your family history.
Genetic information
Genetic testing
How you find out about variants
Genetic testing for variants in the YES1 gene usually uses a blood or saliva sample, and some cancer tests examine tumor tissue instead. The lab reads the DNA sequence to look for changes in the YES1 gene, often as part of a multigene panel, then compares the result with reference sequences to classify any variant.
When should I consider getting a genetic test?
There is not yet a broadly established reason to have inherited genetic testing just for the YES1 gene. Testing decisions are usually based on your personal health history, family history, and whether a doctor is looking for changes in a tumor rather than genes passed down through a family.
A genetic result is only one part of your health story
A genetic finding can provide useful information, 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, influence how the body functions. For some conditions, especially those shaped by many genes, genetic information offers context rather than certainty and is most helpful when considered with other parts of care. In other situations, a genetic result can give a clear answer. In areas such as medication response, genetic results may help put individual experiences into perspective.
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. Because of this, the same medication may work better for some people, have less effect in others, or cause more side effects in some individuals.
What is Pharmacogenetics?
Pharmacogenetics is the area of study that examines how genetic variation affects the way people respond to medicines. It focuses on gene drug relationships to help explain why the same treatment may work differently from one person to another. For many medications, genes influence 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 YES1 gene
When should I seek medical advice?
There is not yet a broadly confirmed role for this gene in predicting medication response, so general concerns about medicines, side effects, or new symptoms are best discussed with your doctor. In cancer research, YES1 changes are being studied because they may affect how some tumors respond to certain targeted treatments, but this is not yet standard guidance for routine care.
History
The YES1 gene entered cancer research through work on tumor causing viruses in the late 20th century, when scientists found a viral gene called v-yes and then identified its human counterpart. In recent decades, awareness of this gene’s role has grown as researchers placed it within the SRC family, a group of genes important in early cancer biology. That discovery helped show how altered versions of normal human genes could contribute to uncontrolled cell growth. From these first observations, research expanded steadily, and YES1 became part of the broader story of how cancer genes were mapped and studied. Today, its history is mainly important for what it taught medicine about the genetic roots of cancer.
