The TRIM37 gene helps cells control growth and keep their internal structure organized during development. This gene plays an important role in how tissues form and mature before and after birth. If both copies carry a disease-causing variant, a person can have MULIBREY syndrome, a rare inherited condition linked to short stature, heart involvement, and changes in the liver, muscles, and metabolism. TRIM37 is mainly known in medical genetics rather than public culture.
What is a gene?
Genes are stretches of DNA that carry instructions your cells use to make molecules or regulate activities in the body. Some genes provide the directions for producing proteins, the functional parts of cells. Others mainly guide when certain processes take place, where they occur, and how strongly they run. Together, genes affect how the body develops and works, and they can also shape how you respond to food, stress, or medications. For a deeper look at this topic, you can find more in the LearnHub.
Overview
TRIM37Gene function
What if the gene works
The TRIM37 gene helps cells manage certain proteins and keep important cell structures organized. This supports normal growth, development, and orderly cell division.
Risk
What if the gene does not work
Variants in the TRIM37 gene can cause a growth condition historically called Mulibrey nanism, with short stature and possible heart, liver, and eye changes. Milder to more severe variants can influence when features appear and how strongly they affect someone.
Treatment
What does that mean for your treatment
No TRIM37-specific treatment or drug choice is currently established; care is guided by the person’s symptoms and complications rather than by a medicine that targets the TRIM37 gene. The TRIM37 gene is also being studied in cancer research as a biomarker and possible drug target, but this has not led to routine treatment guidance for inherited TRIM37 variants.
Conditions associated with TRIM37
Gene function
What if the gene works
Your cells rely on the TRIM37 gene to keep several basic jobs organized. It helps manage protein labeling, steady gene control, and the careful setup of cell division. These routine tasks support normal growth and day to day cell function.
The TRIM37 gene helps place small control tags on selected proteins inside cells. These tags can change where a protein works, how active it is, or when it is cleared away.
The TRIM37 gene helps keep the cell's division machinery organized. This supports accurate handling of chromosomes as one cell divides into two, which is part of how the TRIM37 gene helps control cell division.
Inside the nucleus, the TRIM37 gene helps fine tune which genes are more active or kept quieter. This steady control supports normal cell identity and day to day cell work.
What is a variant?
A genetic variant is a slight difference in the DNA sequence within a gene. Variants are common and help explain normal differences among people, such as appearance, metabolism, or the way the body responds to environmental influences. Many do not cause any noticeable effect and are simply part of natural genetic variation. Sometimes, though, a variant changes how a gene works more substantially and can contribute to or cause a genetic condition.
Genetic variants
What if the gene does not work
Variants in the TRIM37 gene can make the TRIM37 protein shorter, unstable, or less able to tag other proteins for cellular control and cleanup. In practical terms, TRIM37 gene variant effects range from milder changes that leave some protein activity to more severe variants that largely switch the protein off. This loss of function can disrupt normal cell organization and growth, and more severe variants are often linked to earlier or more marked features of MULIBREY syndrome.
How variants are linked to conditions
Pathogenic variants in the TRIM37 gene cause Mulibrey nanism, a rare inherited condition linked to slow growth, short stature, and heart, liver, and hormone related problems. This TRIM37 gene and Mulibrey nanism link is well established, and finding pathogenic variants in both copies can confirm the diagnosis. People with the condition may also have a higher chance of certain tumors.
A variant is not necessarily a diagnosis
Genetic variants are a usual part of human biology and are widely present in the general population. Most do not have a direct effect on health and simply 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 play a role. In some situations, though, a single well characterized variant in a specific gene is enough to confirm a diagnosis.
Are there things that can increase or change my risk?
For TRIM37, risk is mainly set by inheritance rather than lifestyle. A child is at risk for the related condition when both biological parents carry a harmful TRIM37 change, so family history and parents being related by blood can raise the chance in some families. Once a child has inherited harmful changes in both copies, daily habits do not meaningfully change whether the condition occurs.
Inheritance of TRIM37 variants
TRIM37-related conditions are inherited in an autosomal recessive pattern, which means a person usually needs to inherit one altered copy of the TRIM37 gene from each parent. In families learning how TRIM37 variants are inherited, this usually means both parents are healthy carriers. With each pregnancy, two carrier parents have a 25% chance of having a child with the condition, a 50% chance of having a child who is also a carrier, and a 25% chance of having a child who inherits neither altered copy. Parents can pass TRIM37 variants to sons and daughters equally.
What does my TRIM37 result mean for my family?
For families with a disease-causing change in the TRIM37 gene, close relatives may also carry the same gene change, even if they do not have symptoms. Brothers and sisters of an affected child may also be affected or may be carriers, and other relatives may be carriers as well. This can matter for future pregnancies and for family members who want to understand their own chances of passing it on.
Genetic information
Genetic testing
How you find out about variants
Variants in the TRIM37 gene are found with genetic testing, usually using a blood or saliva sample. In practice, genetic testing for TRIM37 variants works by reading the gene’s DNA sequence and, when needed, checking for missing or extra pieces. Results can show whether a variant may help explain a suspected inherited condition.
When should I consider getting a genetic test?
Genetic testing for the TRIM37 gene may be worth considering when a child has very slow growth starting before birth, short stature, and signs affecting the heart, liver, or other organs that suggest a rare growth condition called MULIBREY syndrome. It can also help when this condition runs in the family or both parents are known carriers.
A genetic result is only one part of your health story
A genetic result can be meaningful, but what it tells you depends on the condition and the specific type of variant. Factors such as lifestyle, environment, age, and medical history also shape how the body functions over time. For some conditions, especially those influenced by many genes, genetic information provides 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 like 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. Two people can take the same treatment and have different results because their bodies may absorb, break down, or react to the drug in different ways. These inherited differences are common and can influence how well a medicine works or how sensitive someone is to side effects. Other factors, such as age, kidney or liver function, and other medicines, also play a part.
What is Pharmacogenetics?
Pharmacogenetics examines how genetic differences affect a person’s response to medications. It studies 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 handles it. This information can support more informed and more personalized treatment choices.

Drugs influenced by the TRIM37 gene
When should I seek medical advice?
There isn't yet a broadly confirmed role for this gene in predicting how medicines work, so questions about treatment, side effects, or changes in your health are best discussed with your doctor or pharmacist.
History
TRIM37 entered medical genetics through studies of MULIBREY syndrome, a rare inherited condition first described in Finland in the 1970s. Clinicians recognized a consistent pattern of growth, heart, and liver findings in affected families long before the gene was identified. From these first observations, research expanded steadily. In 2000, researchers linked the condition to variants in the TRIM37 gene, giving families a clearer genetic explanation. That discovery helped confirm that the condition could be diagnosed at the DNA level and placed TRIM37 within a broader wave of gene findings that reshaped rare disease medicine. The way this gene was viewed has shifted over time, from a clinical mystery seen in a small number of families to a defined part of modern human genetics.
