The WDR37 gene makes a protein that helps cells work with other proteins during early development, especially in the brain, eyes, and inner ears. This gene plays an important role in growth and nervous system development. When a harmful variant disrupts it, a person may have developmental delay, vision or hearing differences, balance problems, short stature, or feeding and growth challenges. WDR37 is mainly discussed in medical genetics because it is linked to a rare developmental condition.
What is a gene?
Genes are stretches of DNA that give your cells instructions for making molecules or directing processes in the body. Some genes hold the code for proteins, the parts of cells that do much of the work. Other genes are used mainly to control when certain processes happen, where they take place, and how strongly they run. Taken together, genes affect how the body develops and functions, and they can shape how you respond to food, stress, or medications.

Overview
WDR37Gene function
What if the gene works
The WDR37 gene makes a protein that helps cells organize interactions between other proteins. It appears to support normal development and function in the brain, eyes, and other organs.
Risk
What if the gene does not work
Pathogenic variants in the WDR37 gene can cause a rare syndrome affecting brain development, vision, the heart, and the genitourinary tract. Effects range from milder developmental delays to broader congenital differences, depending on the variant.
Treatment
What does that mean for your treatment
For people with a pathogenic variant in the WDR37 gene, no WDR37-specific treatment or drug-choice approach is currently established; care is guided by the person’s symptoms and the organs involved rather than by the gene change itself.
Gene function
What if the gene works
Your cells use the WDR37 gene to make a helper protein that supports organized cell activity. This protein belongs to a family that often acts as a platform, helping other proteins come together in the right place. Understanding how the WDR37 gene works in the body helps explain how cells coordinate everyday tasks.
The WDR37 gene makes a protein that helps other proteins gather into working groups inside the cell. By acting like a platform, it supports organized, step by step cell activity.
Its protein is found in the nucleus and nucleolus, areas that help manage gene use and build ribosomes (cell structures that make proteins). This location places it where cells organize many routine tasks.
What is a variant?
A genetic variant is a minor change in a gene’s DNA sequence. These changes are common and help explain normal differences among people, including differences in appearance, metabolism, and the way the body responds to environmental influences. Many variants do not cause any noticeable effects and are simply part of natural genetic variation. Sometimes, though, a variant changes how a gene works more substantially and may contribute to, or cause, a genetic condition.
Genetic variants
What if the gene does not work
Many variants in the WDR37 gene change a single protein building block, which can alter the protein’s shape and weaken how it binds to other proteins inside the cell. This is how WDR37 gene variants affect protein function. Some variants seem milder and may leave partial activity, while more disruptive variants can make the protein unstable or interfere more strongly with cell processes. Greater functional disruption is linked to earlier and broader features in related conditions.
How variants are linked to conditions
Pathogenic variants in the WDR37 gene cause a rare developmental condition often called WDR37-related syndrome. Reported features can include developmental delay, vision differences, growth concerns, and heart or urinary tract differences, although the pattern varies from person to person. A confirmed WDR37 gene variant can help explain this combination of findings and support the diagnosis.
A variant is not necessarily a diagnosis
Genetic variants are a usual part of human biology and are common across the general population. Most do not have a direct effect on health and instead reflect natural human diversity. For many genes, carrying a variant associated with a condition suggests a possible link rather than a confirmed diagnosis, especially when multiple genes and environmental factors also play a role. In some situations, though, one well-characterized variant in a specific gene can be enough to confirm a diagnosis.
Are there things that can increase or change my risk?
For WDR37, risk is mainly shaped by genetics rather than lifestyle. A disease-causing change may happen for the first time in a child or be passed on from an affected parent, which can raise the chance in a family. There is not enough evidence to say that diet, exercise, or other everyday exposures change this risk.
Inheritance of WDR37 variants
WDR37-related conditions are inherited in an autosomal dominant pattern, which means one changed copy of the WDR37 gene can be enough to cause the condition. In families where a parent carries a disease-causing variant, each child has a 50% chance of inheriting it. Current evidence on how WDR37 gene variants are inherited also shows that many affected people have a new (de novo) variant that was not inherited from either parent.
What does my WDR37 result mean for my family?
For WDR37, the known condition is usually linked to a change in just one copy of the gene, so close relatives such as parents, brothers, sisters, and children may also carry the same result. That means family testing may sometimes be relevant. Many reported WDR37 changes have happened new in the affected child, so a parent does not always carry it.
Genetic information
Genetic testing
How you find out about variants
Genetic testing for WDR37 variants usually uses a blood sample or cheek swab. A lab sequences the WDR37 gene, often as part of a larger gene panel or exome test, to look for variants that may help explain a person’s health findings or show whether a variant runs in a family.
When should I consider getting a genetic test?
Testing for changes in the WDR37 gene may be considered when a child has unexplained developmental delay or several birth differences that affect the eyes, heart, brain, kidneys, or genitals. It can also help when a doctor suspects a rare genetic condition based on this pattern of findings.
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 type of variant involved. Over time, the way the body works is shaped by many other factors too, including lifestyle, environment, age, and medical history. In some conditions, especially those influenced by many genes, genetic information provides context rather than certainty and is most useful when viewed alongside other parts of care. In other situations, a genetic result may offer a clear answer. In areas such as medication response, genetic results can also help put individual experiences into perspective.
Pharmacogenetics
How variants shape your response to medicine
Genetic variation can affect how people respond to medicines. This helps explain why the same treatment works well for one person, has less effect in another, or causes more side effects in someone else. Differences in how the body absorbs, breaks down, transports, or responds to a drug are common, and they can influence both benefit and sensitivity.
What is Pharmacogenetics?
Pharmacogenetics examines how genetic differences affect a person’s response to medications. It studies the links between genes and drugs to help explain why the same treatment can work differently from one person to another. For many medicines, genes influence both how strongly a drug works and how the body processes it. This information can support more informed, individualized treatment decisions. To explore this topic further, more information is available in the LearnHub.
Drugs influenced by the WDR37 gene
When should I seek medical advice?
There is not yet a broadly confirmed role for this gene in how people respond to medicines. For questions about side effects, new symptoms, or whether a treatment is right for you, it is best to speak with your doctor or pharmacist.
History
In recent decades, awareness of the WDR37 gene’s role in human health has grown. WDR37 was first cataloged during large efforts to map and name human genes, but it drew broader medical interest much later. A clearer clinical picture emerged in the late 2010s, when researchers reported people from different families who shared a similar pattern of eye, brain, heart, and developmental features along with variants in the WDR37 gene. From these first observations, research expanded steadily. This shifted WDR37 from a little known gene in genome databases to one recognized in rare disease genetics.
