The ZDHHC24 gene gives your cells instructions for adding a small fatty tag to certain proteins, which helps place them where they need to work. The protein made by this gene helps your cells keep some proteins anchored to cell membranes, and if this process is disrupted, cell signaling and routine cell upkeep may be affected. Some variants in the ZDHHC24 gene may influence how cells grow and communicate.
What is a gene?
A gene is a stretch of DNA that gives your cells instructions they can use to make molecules or regulate processes in the body. Some genes carry the code for proteins, which are the working parts of cells. Other genes mainly guide when certain processes happen, where they happen, and how strongly they are carried out. Taken together, genes affect how the body develops and works, and they can influence how you respond to food, stress, or medications.

Overview
ZDHHC24Gene function
What if the gene works
The ZDHHC24 gene helps cells attach a small fat tag to certain proteins. This step can help proteins reach the right place in the cell and support normal cell signaling.
Risk
What if the gene does not work
Changes in the ZDHHC24 gene may reduce how well cells attach fatty acid tags to certain proteins, which can alter where those proteins sit and how they signal. Milder and more severe variants can affect this process to different degrees.
Treatment
What does that mean for your treatment
No treatment or drug choice is currently guided by pathogenic variants in the ZDHHC24 gene in established clinical guidelines.
Gene function
What if the gene works
Your cells need proteins to be in the right place at the right time. The ZDHHC24 gene helps by making an enzyme that adds a fatty tag to certain proteins. Seeing how the ZDHHC24 gene works helps explain how cells organize proteins at their surface and inside membranes.
The ZDHHC24 gene helps attach a small fatty tag to selected proteins. This process, called palmitoylation (adding a fatty tag to a protein), can help proteins interact with cell membranes.
Many proteins need to sit on or near a cell membrane to do their job. Tagging supported by ZDHHC24 can guide proteins to those membrane areas and help them stay there when needed.
Fat tagging can influence how proteins move through the cell and how long they remain available. This supports orderly protein traffic and steady cell signaling in everyday cell function.
What is a variant?
A genetic variant is a minor difference in a gene’s DNA sequence. These differences are common and help explain normal human variation, such as differences in appearance, metabolism, or the way the body responds to environmental influences. Many do not have any noticeable effect and are simply part of natural genetic diversity. At times, though, a variant can change how a gene works more significantly and may contribute to or lead to a genetic condition.
Genetic variants
What if the gene does not work
Variants in the ZDHHC24 gene can alter the shape or stability of its protein, especially in the active part, which may reduce or abolish its ability to add fatty acid tags to other proteins. Milder missense variants may leave some activity, while more severe truncating or splice variants can sharply lower protein levels or keep the protein from reaching the right part of the cell. This is how ZDHHC24 gene variants may affect protein function.
How variants are linked to conditions
At present, the ZDHHC24 gene does not have a broadly confirmed link to a specific health condition. Research on ZDHHC24 gene variants and health conditions is still developing, so anyone with a confirmed finding in the ZDHHC24 gene should rely on guidance from their doctor or genetic counselor for personal interpretation.
A variant is not necessarily a diagnosis
Variants in genes are a routine part of human biology and are widely found across the population. Most do not directly affect health and simply contribute to normal human diversity. For many genes, having a variant associated with a condition indicates a possible link, not a certain diagnosis, particularly when several genes and environmental influences also play a role. In some situations, though, one well-understood variant in a particular gene is 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 ZDHHC24 gene. Anyone with questions about their personal or family risk can talk with a doctor or genetic counselor.
Inheritance of ZDHHC24 variants
There is not yet a broadly confirmed disease inheritance pattern for the ZDHHC24 gene, so the inheritance of the ZDHHC24 gene variants is still being clarified as research develops. ZDHHC24 is located on chromosome 20, which is an autosome. That means you inherit one copy of the ZDHHC24 gene from each parent.
What does my ZDHHC24 result mean for my family?
There is not yet a broadly confirmed inheritance pattern tied to a specific health condition for ZDHHC24. Understanding of this gene may become clearer as research grows, and the meaning for relatives depends on the exact result and the health concern being looked at. If you have a specific ZDHHC24 result, a doctor or genetic counselor can help explain what it may mean for your family.
Genetic information
Genetic testing
How you find out about variants
To find out whether you carry a variant in the ZDHHC24 gene, clinicians use ZDHHC24 genetic testing, which reads the DNA code from a blood sample, saliva, or cheek swab. Results may show no variant, a known disease-causing variant, or a variant of uncertain significance, meaning the change is not yet clearly understood.
When should I consider getting a genetic test?
There is not yet a broadly established, ZDHHC24-specific clinical reason for genetic testing. Decisions about testing are best made with a doctor or genetic counselor based on your symptoms, personal health history, and family history.
A genetic result is only one part of your health story
A genetic result can provide valuable insight, but how much it explains varies by the condition and the kind of variant involved. Many factors, including lifestyle, environment, age, and medical history, influence how the body functions over time. For some conditions, especially those shaped by many genes, genetic information provides context rather than certainty and is best interpreted alongside 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 personal experiences into context.
Pharmacogenetics
How variants shape your response to medicine
Genetic variation can affect how people respond to medicines. This happens because inherited differences can change how the body absorbs, breaks down, transports, or responds to a drug. As a result, the same medication may work better for some people, work less well for others, or cause more side effects in some than in others.
What is Pharmacogenetics?
Pharmacogenetics examines how differences in genes affect the way people respond to medications. It focuses on gene and drug patterns to help explain why the same treatment may work differently from one person to another. For many medicines, genes influence either how strongly a drug works or how the body handles it. This understanding can support more informed and more individualized treatment decisions.

Drugs influenced by the ZDHHC24 gene
When should I seek medical advice?
There is not yet a broadly confirmed role for this gene in guiding medication choice or response, so any concerns about side effects, new symptoms, or how well a treatment is working are best discussed with your doctor.
