The POMP gene helps your cells build proteasomes, which are the cell’s protein recycling units. Every cell in your body uses this gene to keep that cleanup system working. If the gene does not work properly, unwanted proteins can build up and may lead to ongoing inflammation, skin changes, and other symptoms. Pathogenic variants in the POMP gene are linked to rare inherited conditions that can affect the skin and immune system.
What is a gene?
Genes are stretches of DNA that provide cells with instructions for making molecules or directing processes in the body. Some genes hold the information needed to make proteins, which are the working parts of cells. Other genes are used mainly to regulate when certain processes happen, where they take place, and how strongly they run. In combination, genes influence how the body develops and functions, and they can shape how you respond to food, stress, or medications.

Overview
POMPGene function
What if the gene works
Your cells use the POMP gene to help build proteasomes, the cell’s protein recycling units. This supports the removal of worn out or damaged proteins and helps cells keep normal balance and function.
Risk
What if the gene does not work
Variants in the POMP gene can cause a rare scaly skin condition or an autoinflammatory condition with repeated inflammation and immune problems. Effects can range from milder to more severe, influencing when symptoms start and which features appear.
Treatment
What does that mean for your treatment
No treatment or drug choice is currently guided specifically by a pathogenic variant in the POMP gene. In early clinical reports, POMP-related autoinflammation has shown response to JAK inhibitor treatment in some people, but this remains an emerging approach rather than an established gene-specific standard.
Conditions associated with POMP
Gene function
What if the gene works
Your cells constantly make, use, and replace proteins. The POMP gene helps keep this cleanup and recycling system running by supporting the build of proteasomes, the structures that remove proteins your cells no longer need. Understanding how the POMP gene works helps explain how cells stay balanced from day to day.
POMP helps cells build the proteasome, the core part of the cell’s protein disposal system. It supports the final assembly steps so this structure can become fully active.
By helping proteasomes mature, the POMP gene supports controlled breakdown of proteins that are worn out, damaged, or no longer needed. This helps cells keep protein levels balanced and recycle building blocks for new proteins.
POMP also helps assemble the immunoproteasome, a version of this cleanup system used often during immune activity. This lets cells prepare small protein pieces for immune display, which helps the body monitor what is happening inside cells.
What is a variant?
A genetic variant is a small change in the DNA sequence of a gene. These changes are common and help shape normal human differences, such as appearance, metabolism, or how the body responds to environmental influences. Many variants do not have any noticeable effect and are simply part of natural genetic variation. In some cases, 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 POMP gene often reduce or alter the POMP protein, which can disrupt proteasome assembly and lower the cell's ability to clear unwanted proteins. This is how variants influence the POMP gene's function at the cellular level, leading to protein buildup and cell stress. Milder variants may leave some activity, while more severe variants can cause a larger loss of proteasome function. In POMP-related conditions, that difference can shape which features appear and when they begin.
How variants are linked to conditions
Pathogenic variants in the POMP gene cause two main rare conditions. The best established links are the POMP gene and KLICK syndrome, a skin condition present from birth, and proteasome-associated autoinflammatory syndrome, a condition with repeated inflammation, rash, immune problems, and poor growth. These are monogenic conditions, so a confirmed pathogenic variant can establish the diagnosis.
A variant is not necessarily a diagnosis
Genetic variants are a usual part of human biology and are widely found in the general population. Most do not directly affect health and simply contribute to natural human variation. For many genes, carrying a variant associated with a condition suggests a possible link rather than a definite diagnosis, especially when several genes and environmental factors also play a part. In some situations, though, a single well-characterized variant in a specific gene can be 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 health risk related to the POMP gene. For many living with a disease-causing POMP change, risk is mostly tied to the genetic change itself, while symptoms and severity can still vary from one person to another.
Inheritance of POMP variants
The inheritance pattern for POMP-related conditions can differ depending on the specific variant and condition. In practical terms, how POMP gene variants are inherited may be autosomal recessive in KLICK syndrome, where a child inherits one altered copy from each parent, or autosomal dominant in POMP-related autoinflammation, where one altered copy can be enough and each child of an affected parent has a 50% chance of inheriting it. Some autosomal dominant POMP variants arise as a new variant and are not inherited from either parent.
What does my POMP result mean for my family?
POMP results can have different family implications because this gene is linked to more than one inherited condition. Some POMP-related conditions run in families in a dominant way, so a parent, child, brother, or sister may also carry the same change, while some cases happen for the first time in one person and are not inherited from either parent. Other POMP-related conditions are recessive, which means relatives may be healthy carriers.
Genetic information
Genetic testing
How you find out about variants
Genetic testing for POMP variants usually uses a blood or saliva sample to read the POMP gene and look for changes in its DNA code. It can show whether a variant is present, but the result must be interpreted with your symptoms and family history because some variants do not explain disease.
When should I consider getting a genetic test?
Consider genetic testing for the POMP gene if there is a pattern of unexplained repeated inflammation, frequent infections, low blood counts, or certain inherited skin changes such as very thick, scaly skin from early life. Testing can also help when these features run in a family or when a doctor suspects a rare immune or skin condition linked to POMP.
A genetic result is only one part of your health story
A genetic result can be informative, but its significance depends on the condition involved and the kind of variant that is present. Over time, many factors, including lifestyle, environment, age, and medical history, also influence how the body functions. For some conditions, particularly those shaped by many genes, genetic information provides context rather than certainty and makes the most sense when considered alongside the rest of a person’s care. In other situations, a genetic result may give a clear answer. In areas like medication response, genetic findings can also help put individual experiences into context.
Pharmacogenetics
How variants shape your response to medicine
Genetic variation can affect how your body handles certain medicines, so the same treatment may work a little differently from one person to another. Some people break down a drug more slowly or more quickly, while others may be more or less sensitive to its effects. This common biological difference can influence how well a treatment works and how likely someone is to notice side effects.
What is Pharmacogenetics?
Pharmacogenetics examines how genetic differences can affect the way a person responds to medications. It looks at connections between genes and drugs to help explain why the same treatment may work differently from one person to another. For many medicines, genes can influence how strongly a drug works or how the body handles it. This information can support more informed, more individualized treatment decisions. More on this topic is available in the LearnHub.
Drugs influenced by the POMP 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 which side effects may happen, so any medication concerns are best discussed with your doctor.
History
The POMP gene entered medical genetics through basic research on how cells build proteasomes, the structures that break down worn out proteins. In the late 1990s and early 2000s, scientists identified human POMP as a key helper in proteasome assembly, building on earlier work in yeast. From these first observations, research expanded steadily. Later, doctors linked variants in the POMP gene to rare inherited skin conditions and to autoinflammatory illness, which causes repeated episodes of inflammation. These findings moved POMP from a laboratory topic to a clinically relevant gene. Over time, descriptions became more precise as genetic testing connected specific POMP variants with different patterns of disease.
