The ZDHHC14 gene helps cells attach a small fat tag to certain proteins, which helps those proteins reach the right place and work properly, especially in nerve cells. If this gene does not work well, some proteins may be misplaced or less stable, and cell signaling can become less organized. This gene plays an important role in how brain cells maintain the equipment they need to send and receive signals. Most people never hear about the ZDHHC14 gene outside genetics or research, but it helps explain one of the basic ways cells stay coordinated.
What is a gene?
Genes are stretches of DNA that hold instructions your cells use to make molecules or manage activities in the body. Some genes provide the directions for producing proteins, which are the working parts of cells. Other genes mainly regulate when certain processes happen, where they occur, and how active they are. Together, genes affect how the body develops and works, and they can influence how you respond to food, stress, or medications. More information on this topic is available in the LearnHub.
Overview
ZDHHC14Gene function
What if the gene works
The ZDHHC14 gene helps cells attach small fat tags to certain proteins, supporting where those proteins go and how they work. This is especially important in nerve cells.
Risk
What if the gene does not work
Changes in the ZDHHC14 gene can reduce how well cells add fatty acid tags to certain proteins, which helps them reach the right place and work normally. Milder and more severe variants may leave different amounts of this activity intact.
Treatment
What does that mean for your treatment
No ZDHHC14-specific treatment or management approach is currently established.
Gene function
What if the gene works
Your cells rely on the ZDHHC14 gene to help certain proteins settle into the right membrane location. It does this by adding a small fatty tag that changes how those proteins behave inside the cell. Understanding this ZDHHC14 gene function helps show how cells organize everyday signaling.
The ZDHHC14 gene helps cells attach a small fatty acid tag to selected proteins, a step called palmitoylation (adding a fat like group). This tag can change how a protein interacts with membranes and other cell parts.
By adding this tag, the ZDHHC14 gene helps guide proteins to the right membrane areas inside the cell. Proper placement helps proteins work where they are most needed.
Many proteins modified by ZDHHC14 are involved in cell signaling. This helps everyday communication inside cells stay organized and steady.
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, such as differences in appearance, metabolism, or the way the body responds to environmental influences. Many variants have no noticeable effect and simply reflect natural genetic variation. In some cases, though, a variant can alter how a gene works more substantially and may play a role in, or cause, a genetic condition.
Genetic variants
What if the gene does not work
Variants in the ZDHHC14 gene can change the shape, stability, or cell location of its protein, which may reduce how well it adds fatty acid tags to other proteins. This is how ZDHHC14 gene variants affect protein function: some variants cause a mild drop in enzyme activity, while more severe variants can sharply reduce activity or lead to a shortened protein that is quickly broken down. These changes may also weaken the protein's interactions with its targets.
How variants are linked to conditions
The ZDHHC14 gene does not yet have a broadly confirmed link to a specific health condition, though research on how variants of the ZDHHC14 gene are linked to conditions is still developing. If you carry a confirmed variant in the ZDHHC14 gene, your doctor or genetic counselor can explain what it may mean in the context of your personal and family history.
A variant is not necessarily a diagnosis
Genetic variants are common and are a normal feature of human biology. Most do not directly affect health and simply contribute to the natural diversity seen among people. For many genes, having a variant associated with a condition points to a possible link rather than a certain diagnosis, particularly when several genes and environmental influences play a role. In some situations, though, one well-characterized variant in a particular gene is enough to confirm the 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 ZDHHC14 gene. If a change in ZDHHC14 has been found in your results, a doctor or genetic counselor can help explain what it may mean for your personal and family risk.
Inheritance of ZDHHC14 variants
There is not yet a broadly confirmed, disease-specific Mendelian pattern for how variants of the ZDHHC14 gene are inherited, so answers to how are variants of the ZDHHC14 gene inherited remain cautious and may change as research develops. The ZDHHC14 gene is located on chromosome 6, which is an autosome. That means every person inherits one copy of the ZDHHC14 gene from each parent, regardless of sex.
What does my ZDHHC14 result mean for my family?
There is not yet a broadly confirmed inheritance pattern tied to a specific health condition for the ZDHHC14 gene, and this picture may become clearer as research grows. If you have a specific ZDHHC14 result, what it means for relatives depends on the exact change found and why the testing was done.
Genetic information
Genetic testing
How you find out about variants
To check for changes in the ZDHHC14 gene, doctors use genetic testing for ZDHHC14 variants, usually on a blood sample, saliva, or a cheek swab. The lab reads your DNA sequence and compares it with the usual gene code to see whether a variant is present.
When should I consider getting a genetic test?
There is not yet a broadly established ZDHHC14-specific reason for genetic testing in routine care. Testing decisions are usually based on your health history, symptoms, and family history, often as part of a broader genetics evaluation.
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 offers context rather than certainty and is best viewed alongside 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. Small differences in DNA can change how the body breaks down a drug, moves it through the bloodstream, or responds to it at its target, so the same treatment may work better for some people than for others. This is a common part of normal human variation and can influence both how well a medicine helps and how likely someone is to notice side effects.
What is Pharmacogenetics?
Pharmacogenetics examines how genetic variation can shape a person’s response to medications. It looks at relationships between genes and drugs to help explain why the same treatment may work differently from one person to another. For many medicines, genes can affect both how strongly a drug works and how the body handles it. This information can support more personalized and informed treatment decisions.

Drugs influenced by the ZDHHC14 gene
When should I seek medical advice?
There is not yet a broadly confirmed role for this gene in how people respond to medicines, so any concerns about side effects, new symptoms after starting a treatment, or questions about changing medication are best discussed with your doctor.
