The USP31 gene helps cells control protein recycling and important stress signals, including some linked to inflammation. This gene plays an important role in removing small protein tags that act like labels, so messages inside the cell stay balanced. If it does not work properly, cells may respond less well to stress or damage, which can disrupt normal cell function.
What is a gene?
A gene is a piece of DNA that holds instructions cells use to make molecules or manage processes in the body. Some genes provide the directions for making proteins, which do much of the work inside cells. Others mainly regulate when certain processes happen, where they occur, and how strongly they are carried out. Taken together, genes affect how the body grows and works, and they can also influence how you respond to food, stress, or medications.

Overview
USP31Gene function
What if the gene works
The USP31 gene helps cells control protein tags called ubiquitin, which guide signaling and protein turnover. By trimming these tags, it supports cell communication and immune signaling.
Risk
What if the gene does not work
Milder to more severe variants in the USP31 gene can reduce or disrupt how cells remove protein tags and control NF-κB signaling, a pathway that helps manage inflammation and cell stress.
Treatment
What does that mean for your treatment
No USP31-specific treatment or management approach is currently established, and a pathogenic or loss-of-function variant in the USP31 gene does not currently guide routine drug choices in clinical guidelines.
Gene function
What if the gene works
Small protein tags act like labels inside your cells, and the USP31 gene helps manage them. These labels influence how proteins behave, including how long they stay active. By adjusting them, the USP31 gene supports orderly cell communication, especially in pathways involved in normal immune and stress responses.
The USP31 gene helps remove small protein tags that act like labels inside cells. Taking labels off can change how long a protein lasts, where it goes, or how active it is.
By adjusting these labels, the USP31 gene helps balance cell messages linked to immune and stress responses. This is a main part of how the USP31 gene helps control protein tags and immune signaling in everyday cell function.
What is a variant?
A genetic variant is a small difference in the DNA sequence of a gene. These changes are common and are part of normal human diversity, including differences in appearance, metabolism, or in how the body responds to environmental influences. Many variants have no noticeable effect and simply represent natural genetic variation. In some situations, however, a variant can change the function of a gene more substantially and may contribute to or cause a genetic condition.
Genetic variants
What if the gene does not work
Variants in the USP31 gene may change the enzyme's shape, stability, or ability to remove ubiquitin, a small protein tag cells use to manage signaling and protein turnover. This is how variants influence the USP31 gene's function: some changes only partly lower activity, while more disruptive variants can truncate the protein or make it break down early, leaving little working enzyme in the cell. The result can be weaker protein interactions and less controlled cell signaling.
How variants are linked to conditions
Variants in the USP31 gene do not yet have a broadly confirmed link to a specific inherited health condition, although research on USP31 gene variants and disease is still developing. Anyone with a diagnosis related to the USP31 gene should rely on guidance from their doctor or genetic counselor rather than general information.
A variant is not necessarily a diagnosis
Genetic variants are a routine part of human biology and are widespread 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 definitive diagnosis, especially when more than one gene and environmental factors are involved. 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 is not yet broadly confirmed evidence on specific factors that increase or reduce health risk related to the USP31 gene. If you have a USP31 gene change or a family history that concerns you, a doctor or genetic counselor can help explain what it may mean for your personal risk.
Inheritance of USP31 variants
There is not yet a broadly confirmed, disease specific inheritance pattern for the USP31 gene, so a single answer such as dominant or recessive is not currently established. As research develops, the picture of USP31 gene inheritance may become clearer. The USP31 gene is located on chromosome 16, which is an autosome, so you inherit one copy from each parent.
What does my USP31 result mean for my family?
There is not yet a broadly confirmed inherited pattern tied to a specific health condition for the USP31 gene, and understanding may change as research grows. If you have a USP31 result and want to know what it could mean for relatives, a doctor or genetic counselor can explain it in the context of your exact finding and family history.
Genetic information
Genetic testing
How you find out about variants
To find out about USP31 variants, genetic testing reads the DNA sequence of the USP31 gene from a blood sample, saliva, or sometimes a cheek swab. Laboratories may examine USP31 alone or as part of a larger panel, then compare any variant found with reference sequences and clinical databases.
When should I consider getting a genetic test?
There is not yet a widely used medical reason to test the USP31 gene on its own. Testing decisions are usually based on your personal health and family history, ideally with guidance from a doctor or genetic counselor.
A genetic result is only one part of your health story
A genetic result can provide useful insight, but how much it explains depends on the condition and on the type of variant involved. Over time, many factors, including lifestyle, environment, age, and medical history, influence how the body functions. In some conditions, especially those shaped by many genes, genetic information provides context rather than certainty and is best considered alongside other parts of care. In other situations, a genetic result may offer 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 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. This helps explain why the same medication works well for one person but less well for another, or why some people are more sensitive to side effects. These differences are common and are one part of the bigger picture, alongside age, liver and kidney function, other medicines, and overall health.
What is Pharmacogenetics?
Pharmacogenetics examines how differences in genes affect the way someone responds to medication. It studies the relationship between genes and drugs to help explain why the same treatment may work differently from one person to another. With many medicines, genes can influence both how strongly a drug works and how the body handles it. This information can support more informed, individualized treatment decisions.

Drugs influenced by the USP31 gene
When should I seek medical advice?
There is not yet a broadly confirmed role for this gene in guiding medication response, so questions about side effects, drug safety, or whether a treatment is working are best discussed with your doctor.
