The UFM1 gene helps cells tag certain proteins so they can cope with stress and keep important cell functions running normally. This process is especially important in the brain, where growing and highly active cells need careful protein control. If the UFM1 gene does not work properly, brain development can be affected and some people may have developmental delay, seizures, low muscle tone, or movement problems. Rare harmful variants in the UFM1 gene are linked to an inherited neurologic condition that often begins early in life.
What is a gene?
A gene is a section of DNA that carries instructions your cells use to make molecules or regulate processes in the body. Some genes hold the information needed to make proteins, which are the working parts of cells. Others mainly help direct when certain processes happen, where they happen, and how strongly they run. Taken together, genes affect how the body develops and works, and they can also shape how you respond to food, stress, or medications.

Overview
UFM1Gene function
What if the gene works
The UFM1 gene helps cells attach a small tag to certain proteins. This supports protein quality control, stress responses, and healthy development, especially in the brain and blood-forming tissues.
Risk
What if the gene does not work
More disruptive variants in the UFM1 gene can cause a rare early onset brain condition with developmental delay, seizures, small head size, and poor growth, while milder variants may lead to later or less severe effects.
Treatment
What does that mean for your treatment
No treatment or drug choice specific to the UFM1 gene is currently established in clinical guidelines. The UFM1 gene is being studied as a possible biomarker and drug target in some cancers and conditions linked to cell stress, but this has not yet changed routine care.
Conditions associated with UFM1
Gene function
What if the gene works
In your cells, the UFM1 gene helps manage how certain proteins are handled during everyday work. Its main job is to provide a small protein tag that fine tunes other proteins, especially where cells make and process new proteins. Understanding what the UFM1 gene does in the body helps explain how cells stay balanced during routine demands.
Inside your cells, UFM1 is attached to selected proteins in a process called UFMylation (adding a small protein tag). This tag can fine tune how those proteins work, where they act, or which cell partners they join.
This pathway is especially active around the endoplasmic reticulum (the cell area that folds and processes proteins) and ribosomes, where proteins are made. It supports smooth protein production and orderly handling of newly made proteins.
By adjusting key proteins, UFM1 activity helps cells stay steady when protein workload rises. This supports protein quality control, which means keeping proteins properly made, folded, and placed.
What is a variant?
A genetic variant is a small change in the DNA sequence within a gene. These changes are common and help shape normal human diversity, including differences in appearance, metabolism, or how the body responds to environmental influences. Many variants do not cause any noticeable effect and simply represent natural genetic variation. Sometimes, though, 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 UFM1 gene can lower how much UFM1 protein a cell makes, change its shape, or weaken its ability to attach to other proteins in this protein tagging system. In practical terms, how UFM1 gene variants affect cell function ranges from milder changes with partial activity to more severe variants that nearly shut the pathway down. When the functional loss is greater, symptoms in the related neurologic condition often begin earlier and can be more severe.
How variants are linked to conditions
Pathogenic variants in both copies of the UFM1 gene cause a rare inherited neurologic condition called hypomyelinating leukodystrophy 14. This UFM1 gene condition usually starts in infancy and is linked to severe developmental delay, seizures, low muscle tone, feeding problems, and a smaller than expected head size. A founder variant has also been reported in some people of Roma ancestry.
A variant is not necessarily a diagnosis
Genetic variants are common across the general population and are a usual part of human biology. Most do not directly affect health and instead reflect natural differences among people. For many genes, having a variant connected with a condition points to a possible association, not a certain diagnosis, particularly when more than one gene and environmental influences play a role. Still, in some situations, one well-understood 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 related to UFM1. For many living with a disease-causing UFM1 change, risk is mainly tied to the genetic change itself rather than lifestyle or environmental factors.
Inheritance of UFM1 variants
When people look up how UFM1 gene variants are inherited, the well-established pattern for UFM1-related conditions is autosomal recessive. This means a child usually inherits one altered copy of the UFM1 gene from each parent. Parents who carry one variant are typically unaffected carriers. When both parents carry a UFM1 variant, each pregnancy has a 25% chance of the child inheriting both altered copies, a 50% chance of being a carrier, and a 25% chance of inheriting neither variant.
What does my UFM1 result mean for my family?
For UFM1, the best-known health conditions are inherited in a recessive pattern, so family members are most often affected only when they inherit a changed copy from each parent. This means parents are usually healthy carriers, and brothers or sisters may also be carriers or, in some families, may have the condition. Close relatives may want to learn whether the same UFM1 change runs in the family.
Genetic information
Genetic testing
How you find out about variants
Testing for variants in the UFM1 gene usually uses a blood or saliva sample, which a lab analyzes with sequencing. Genetic testing for UFM1 variants can show whether you carry a change linked to an inherited condition, and the result is read alongside symptoms and family history.
When should I consider getting a genetic test?
Testing for changes in the UFM1 gene may be considered when a baby or child has unexplained early seizures, major developmental delay, low muscle tone, or brain scan findings suggesting a serious inherited nerve condition. It can also be relevant after an affected child in the family or when parents are blood relatives.
A genetic result is only one part of your health story
A genetic finding can provide meaningful insight, but how much it reveals depends on the condition and the type of variant involved. Many factors, including lifestyle, environment, age, and medical history, shape how the body works over time. For some conditions, especially those influenced by many genes, genetic information provides context rather than certainty and is most useful when considered alongside other parts of care. In other situations, a genetic result can offer a clear answer. In areas such as medication response, these results can help place individual experiences in context.
Pharmacogenetics
How variants shape your response to medicine
Genetic variation can affect how people respond to medicines. Small differences in a person’s 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 may work well for one person, seem less helpful for another, or cause more side effects in someone else.
What is Pharmacogenetics?
Pharmacogenetics examines how genetic differences can affect the way people respond to medications. It looks at connections between genes and drugs to help explain why the same treatment may work differently in different people. With many medicines, genes can influence how strong a drug’s effects are or how the body handles it. This information can support treatment decisions that are both more informed and more individualized. To explore this subject further, you can learn more in the LearnHub.
Drugs influenced by the UFM1 gene
When should I seek medical advice?
There is not yet a broadly confirmed role for this gene in predicting how medicines will work or what side effects they may cause, so questions about medications, side effects, or new symptoms are best discussed with your doctor or pharmacist.
History
The UFM1 gene entered the scientific literature in the early 2000s, when researchers were mapping new genes involved in basic cell regulation. Initially understood only through visible traits, later recognized as tied to a specific gene, this area of research grew as scientists identified UFM1 as part of a newly described tagging system in cells. From these first observations, research expanded steadily, and related enzymes in the same pathway were described over the following years. Interest increased further when studies linked changes in the UFM1 pathway to rare inherited conditions and developmental differences. These historical steps shaped today’s understanding of UFM1 as a distinct and important part of human genetics.
