The ZDHHC20 gene helps cells attach a small fat tag to certain proteins, which helps those proteins reach the right place and work as they should. This gene plays an important role in cell signaling, the cell surface, and how tissues handle growth and repair. If the ZDHHC20 gene does not work properly, protein control inside cells can change, which may affect how cells behave. It is mainly known in medical research rather than public culture.
What is a gene?
A gene is a section of DNA that carries instructions your cells use to make molecules or to regulate processes throughout the body. Some genes provide the directions for producing proteins, which are the parts of cells that do much of the work. Others mainly guide when certain processes happen, where they happen, and how active they are. Taken together, genes affect how the body grows and works, and they can also influence how you react to food, stress, or medicines. For a deeper look at this topic, you can find more in the LearnHub.
Overview
ZDHHC20Gene function
What if the gene works
The ZDHHC20 gene helps cells attach small fat tags to certain proteins. This helps guide where those proteins sit in cell membranes and how they send signals.
Risk
What if the gene does not work
Milder to more severe variants in the ZDHHC20 gene can reduce how well cells attach a small fatty tag to certain proteins. This may change where those proteins sit in the cell membrane and how they send signals.
Treatment
What does that mean for your treatment
No ZDHHC20-specific treatment or management approach is currently established for pathogenic or loss-of-function variants in the ZDHHC20 gene. The ZDHHC20 gene is being studied in early research because it helps add a fatty tag to some proteins involved in cancer growth and viral infection, but this has not led to guideline-based drug choices.
Gene function
What if the gene works
Your cells use the ZDHHC20 gene to place a small fat tag on certain proteins. A key part of how the ZDHHC20 gene helps proteins attach to cell membranes is this tagging step, which can guide where those proteins sit and how long they stay there. That supports smooth everyday cell communication.
The ZDHHC20 gene helps cells attach a small fat tag to selected proteins. This process, called palmitoylation (adding a fatty group), helps certain proteins interact with membranes.
Many proteins need this fat tag to reach the right membrane surface. ZDHHC20 supports correct protein positioning so cell activities happen in the right place.
The added fat tag can help some proteins stay attached to membranes instead of drifting away. This helps keep important proteins available where cells need them.
By helping membrane proteins stay in place, the ZDHHC20 gene supports orderly signaling inside and between cells. This helps routine cell responses stay coordinated.
What is a variant?
A genetic variant is a minor change in the DNA sequence within a gene. These changes are common and are part of normal human diversity, such as differences in appearance, metabolism, or the way the body responds to environmental influences. Many variants do not cause any noticeable effects and simply represent natural genetic variation. In some situations, though, a variant can change how a gene works more substantially and may contribute to or cause a genetic condition.
Genetic variants
What if the gene does not work
Variants in the ZDHHC20 gene can change the shape, stability, or cell location of its protein, which may reduce how well it adds fatty acid tags to partner proteins. When looking at how variants in the ZDHHC20 gene affect protein function, milder changes may only partly lower activity, while more severe variants can disrupt the active site or lead to little or no working protein. These differences can change how strongly cell signaling and protein trafficking are affected.
How variants are linked to conditions
Current research on how variants of the ZDHHC20 gene are linked to conditions is still developing, and the ZDHHC20 gene does not yet have a broadly confirmed link to a specific health condition. Anyone with a confirmed ZDHHC20-related diagnosis should rely on guidance from their doctor or genetic counselor rather than general information.
A variant is not necessarily a diagnosis
Variants in genes are a routine feature of human biology and are found throughout the general population. Most do not directly affect health and simply reflect normal human variation. For many genes, having a variant tied to a condition suggests a possible association rather than a certain diagnosis, especially when several genes and environmental factors play a role. In some situations, though, a single well understood 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 ZDHHC20 gene. Risk, if a change is found, can depend on the exact variant and the health condition being looked at. Anyone with concerns about personal or family risk should speak with a doctor or genetic counselor.
Inheritance of ZDHHC20 variants
There is not yet a broadly confirmed Mendelian pattern for how ZDHHC20 gene variants are inherited in relation to a specific human genetic condition. Current knowledge about ZDHHC20 gene inheritance is still developing, so this may become clearer as research grows. The ZDHHC20 gene is located on chromosome 13, which is an autosome. That means you inherit one copy of the ZDHHC20 gene from your mother and one copy from your father.
What does my ZDHHC20 result mean for my family?
There isn't yet a broadly confirmed inheritance pattern tied to a specific condition for ZDHHC20, though this understanding can change as research develops. If you have a specific ZDHHC20 result and questions about what it could mean for your family, a doctor or genetic counselor can explain it in the context of your personal and family history.
Genetic information
Genetic testing
How you find out about variants
Genetic testing for variants in the ZDHHC20 gene reads the DNA sequence from a blood sample, saliva sample, or cheek swab. A lab compares your result with a reference sequence to check for a variant and then classifies any finding using established evidence.
When should I consider getting a genetic test?
There is not yet a broadly established reason to get genetic testing just for the ZDHHC20 gene. Testing is usually considered in the wider context of your symptoms, medical findings, or family history, together with 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 reveals depends on the condition and the kind of variant involved. How the body functions over time is also shaped by many factors, including lifestyle, environment, age, and medical history. 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 offer a clear answer. In areas like 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. Small differences in genes can change how the body breaks down a drug, moves it through the body, or how strongly the drug acts on its target. That helps explain why the same medication may work well for one person, work less well for another, or cause more side effects in someone who is more sensitive to it.
What is Pharmacogenetics?
Pharmacogenetics is the area of study focused on how genetic differences affect the way people respond to medications. It examines relationships 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 understanding can support more informed and more personalized treatment decisions.

Drugs influenced by the ZDHHC20 gene
When should I seek medical advice?
There is not yet a broadly confirmed role for this gene in guiding medication choices. If you have concerns about side effects, a medicine not working as expected, or symptoms after starting a new treatment, talk with your doctor or pharmacist.
