The DVL3 gene helps cells pass along growth signals that shape the skeleton and other body parts during early development. If this gene does not work properly, it can cause Robinow syndrome, a condition that may involve short stature, differences in the face and limbs, and changes in the spine or ribs. Some people with a disease causing variant also have differences in tooth development or the genitals.
What is a gene?
A gene is a stretch of DNA that holds instructions your cells use to make molecules or guide processes in the body. Some genes provide the directions for making proteins, the parts of cells that carry out the work. Other genes mainly control when certain processes happen, where they take place, and how strongly they run. Taken together, genes affect how the body develops and works, and they can shape how you respond to food, stress, or medications.

Overview
DVL3Gene function
What if the gene works
The DVL3 gene helps cells pass along growth signals that guide body patterning. This supports early development, including how bones, the face, and other tissues form.
Risk
What if the gene does not work
Pathogenic variants in the DVL3 gene can cause Robinow syndrome, which affects bone growth and body shape. People may have short stature, facial features typical of the condition, and spine or genital differences, with milder or more marked features.
Treatment
What does that mean for your treatment
A pathogenic variant in the DVL3 gene does not currently change treatment or medication choices through any established clinical guideline. The DVL3 gene is being studied in Wnt signaling research, including as a possible cancer biomarker or drug target, but this has not led to routine care.
Conditions associated with DVL3
Gene function
What if the gene works
Your cells use the DVL3 gene to pass along messages that help tissues grow in an organized way. These signals are especially important while the body is forming, but they also support routine cell behavior later in life. Understanding how the DVL3 gene helps cells communicate during development makes its day to day role easier to picture.
The DVL3 gene helps carry messages from the cell surface to the inside of the cell. This lets cells respond when nearby tissues send Wnt signals, a set of growth and patterning messages used throughout the body.
After a signal arrives, DVL3 helps switch on the right gene activity for that moment. This supports normal decisions about when cells should grow, specialize, or stay in place.
DVL3 helps cells line up and orient themselves within a tissue. This orderly positioning supports body patterning and helps tissues develop with the right shape and structure.
DVL3 also helps coordinate the internal framework that gives cells shape and direction. This can help cells move in a controlled way when tissues are forming or renewing themselves.
What is a variant?
A genetic variant is a minor change in the DNA sequence within a gene. These changes are common and are part of 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 change how a gene works more significantly and may contribute to or cause a genetic condition.
Genetic variants
What if the gene does not work
Pathogenic variants in the DVL3 gene often shift the reading frame near the gene's end. That produces an altered protein with an abnormal tail, a key reason how DVL3 gene variants affect protein function and disturb WNT signaling, a cell messaging system that guides body patterning. Some changes may have milder effects on signaling or partner binding, while more disruptive variants can distort these signals more strongly and are often linked to earlier or more noticeable Robinow syndrome features.
How variants are linked to conditions
Pathogenic variants in the DVL3 gene cause autosomal dominant Robinow syndrome, a condition that can affect growth, facial features, and bone development. People with Robinow syndrome caused by the DVL3 gene may also have differences in the teeth, spine, ribs, hands, or genitals. Because this is a well-established inherited condition, finding a pathogenic DVL3 variant can confirm the diagnosis.
A variant is not necessarily a diagnosis
Genetic variants are a routine part of human biology and are widely found across the general population. Most do not directly affect health and simply reflect natural human variation. 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 understood variant in a particular gene is enough to confirm a diagnosis.
Are there things that can increase or change my risk?
For DVL3, risk is mostly shaped by whether a disease-causing variant is present in the family or happens as a new change. If a parent carries a harmful DVL3 variant, each child has a 50% chance of inheriting it. Lifestyle habits do not meaningfully change the chance of having this condition.
Inheritance of DVL3 variants
DVL3-related conditions are inherited in an autosomal dominant pattern. For families asking how DVL3 variants are inherited, this usually means a person with a disease-causing variant in the DVL3 gene has a 50% chance of passing it to each child, regardless of sex. Some people with a DVL3-related condition are the first in their family to have it because the variant arose new (de novo) in them, rather than being inherited from either parent.
What does my DVL3 result mean for my family?
A disease-causing change in the DVL3 gene is linked to a dominant form of Robinow syndrome, so close relatives such as parents, brothers, sisters, and children may also carry the same change and may want to discuss testing. Each child of someone with the variant can inherit it. Some cases happen for the first time in one person, so a parent does not always have the same gene change.
Genetic information
Genetic testing
How you find out about variants
To find out whether you carry a variant in the DVL3 gene, doctors use DVL3 genetic testing, usually with a blood or saliva sample. A lab reads the gene’s DNA code and compares it with the usual sequence to look for variants. Results may show that a variant is present, absent, or not yet clearly understood.
When should I consider getting a genetic test?
Consider testing for the DVL3 gene if a child or adult has signs of Robinow syndrome, such as short stature, unusual facial features, or differences in the spine, ribs, hands, or genitals, or if it runs in the family. A result can help confirm the cause and clarify family planning risks.
A genetic result is only one part of your health story
A genetic result can provide useful insight, but how much it reveals depends on the condition and the type of variant involved. Over time, many factors, including lifestyle, environment, age, and medical history, also shape how the body functions. In some conditions, especially those influenced by many genes, genetic information offers context rather than certainty and is best viewed alongside other parts of care. In other situations, a genetic result may give 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 influence how your body responds to certain medicines. Small inherited differences can affect how a drug is absorbed, broken down, or used by the body, which helps explain why the same treatment may work well for one person but less well for another. These differences are common and can shape both benefit and side effects, including whether someone is more sensitive to a usual dose.
What is Pharmacogenetics?
Pharmacogenetics examines how differences in genes can shape the way a person responds to medication. By looking at connections between genes and drugs, it helps explain why the same treatment can work differently from one person to another. For many medicines, genes influence how strongly a drug works or how the body handles it. This information can support treatment decisions that are more informed and more personalized. More detail on this topic is available in the LearnHub.
Drugs influenced by the DVL3 gene
When should I seek medical advice?
There is not yet a broadly confirmed role for this gene in guiding medication choice or predicting medication response, so any concerns about medicines, side effects, or treatment changes are best discussed with your doctor.
History
The DVL3 gene entered human genetics through earlier work on the “dishevelled” gene first studied in fruit flies, where researchers noticed it shaped how tissues formed during development. In recent decades, knowledge has built on a long tradition of observing inherited traits. Scientists later identified the human dishevelled gene family, including the DVL3 gene, as this area of research expanded from animal studies to human health. A major milestone came in 2015, when truncating variants in the DVL3 gene were linked to autosomal dominant Robinow syndrome, helping explain the cause of some long-recognized family patterns. From these first observations, research expanded steadily. Today, the DVL3 gene is mainly known in clinical genetics through that discovery and the work that followed.
