The ZDHHC13 gene helps cells attach a small fat tag to certain proteins, which helps them move to the right place and work properly. This gene plays an important role in cell signaling, especially in tissues like the brain, skin, and hair. If it does not work well, some proteins may not function normally, and this can contribute to developmental differences or changes in hair and skin in some people.
What is a gene?
Genes are stretches of DNA that carry instructions your cells use to make molecules or regulate activities in the body. Some genes provide the information needed to produce proteins, the parts of cells that do the work. Other genes mainly guide when certain processes happen, where they happen, and how active they are. Together, genes affect how the body develops and works, and they can also shape how you respond to food, stress, and medications. For a closer look at this topic, you can find more in the LearnHub.
Overview
ZDHHC13Gene function
What if the gene works
The ZDHHC13 gene helps cells attach a fatty tag to certain proteins. This supports where those proteins go and how they work, especially in the skin, hair, and nervous system.
Risk
What if the gene does not work
Milder to more severe variants in the ZDHHC13 gene can reduce how well this enzyme attaches fatty acid tags to selected proteins. When that tagging step is disrupted, protein trafficking, stability, and signaling inside cells may become less controlled.
Treatment
What does that mean for your treatment
No ZDHHC13-specific treatment or drug-selection approach is currently established in clinical guidelines.
Gene function
What if the gene works
The ZDHHC13 gene helps your cells place a small fat tag on selected proteins. This tagging step helps those proteins settle into the right cell membrane areas, where they can do their jobs more smoothly. Understanding how the ZDHHC13 gene works in cells helps show how proteins are guided, positioned, and supported during everyday cell activity.
The ZDHHC13 gene helps attach a small fatty acid to certain proteins, a step called palmitoylation (adding a fat tag). This tag can change how a protein behaves and where it works in the cell.
Many proteins need this fat tag to reach the right membrane surface inside or around the cell. By helping with that placement, the ZDHHC13 gene supports orderly day to day cell activity.
Fat tagged proteins often need to stay in the right spot long enough to pass messages or work with nearby proteins. ZDHHC13 helps support that anchoring, which can make cell signaling more controlled.
What is a variant?
A genetic variant is a small difference in the DNA sequence within a gene. These changes are common and are part of normal human diversity, including differences in appearance, metabolism, or how the body responds to environmental influences. Many variants have no noticeable effect and simply represent natural genetic variation. In some cases, though, a variant can affect how a gene functions more substantially and may contribute to or cause a genetic condition.
Genetic variants
What if the gene does not work
How ZDHHC13 gene variants affect protein function depends on where the DNA change occurs. Many variants alter the enzyme’s shape, stability, or location in the cell, so it adds its fatty tag to other proteins less effectively. Milder variants may leave partial activity, while more severe loss-of-function variants can greatly reduce the amount of working protein or stop its activity entirely.
How variants are linked to conditions
At this time, variants in the ZDHHC13 gene do not yet have a broadly confirmed link to a specific health condition, and research on how ZDHHC13 gene variants are linked to conditions is still evolving. If you carry a change in the ZDHHC13 gene, your doctor or genetic counselor can help interpret it in the context of your personal health and family history.
A variant is not necessarily a diagnosis
Gene variants are a normal feature of human biology and are common across the general population. Most have no direct impact on health and simply reflect natural human diversity. For many genes, carrying a variant tied to a condition suggests a possible association rather than a definite diagnosis, especially when several genes and environmental factors also contribute. In some situations, though, a single well-characterized variant in a particular gene can be 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 ZDHHC13 gene. If a change in ZDHHC13 has been found in you or your family, a doctor or genetic counselor can help explain what it may mean for your personal situation.
Inheritance of ZDHHC13 variants
There is not yet a broadly confirmed Mendelian pattern for how ZDHHC13 gene variants are inherited in a specific human condition, so the picture for ZDHHC13 gene inheritance remains unsettled as research develops. The ZDHHC13 gene is located on chromosome 22, which is an autosome. That means everyone inherits two copies of this gene, one from each parent.
What does my ZDHHC13 result mean for my family?
There isn't yet a broadly confirmed inheritance pattern tied to a specific condition for ZDHHC13, though this understanding can change as research develops. If you have a specific ZDHHC13 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 ZDHHC13 gene usually uses a blood or saliva sample to read the DNA sequence and look for changes. It may be done as part of a multigene panel, exome sequencing, or whole genome sequencing, and the report classifies a finding as pathogenic, likely pathogenic, benign, likely benign, or of uncertain significance.
When should I consider getting a genetic test?
There is not yet a broadly established reason to get genetic testing just for the ZDHHC13 gene. Testing is usually considered as part of a wider genetics evaluation when someone has a personal or family history of an inherited condition, and the decision is best made with a doctor or genetic counselor.
A genetic result is only one part of your health story
A genetic result can be informative, but what it can tell you varies with the condition and the type of variant involved. Many factors, including lifestyle, environment, age, and medical history, also shape how the body works over time. In some conditions, especially those influenced by many genes, genetic information offers context rather than certainty and is most useful when considered 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 your body responds to medicines. Small differences in genes can change how a drug is absorbed, broken down, moved through the body, or how strongly it acts at its target. This helps explain why the same medication may work well for one person, work less well for another, or cause more side effects in someone else. These differences are common and are one of several reasons treatment response can vary from person to person.
What is Pharmacogenetics?
Pharmacogenetics focuses on how differences in a person’s genes can affect their response to medications. It examines gene-drug patterns to help explain why the same treatment may not work the same way for everyone. With many medicines, genes influence both how strongly a drug works and how the body handles it. Understanding this can support treatment choices that are more informed and more tailored to the individual. More information on this topic is available in the LearnHub.
Drugs influenced by the ZDHHC13 gene
When should I seek medical advice?
There is no broadly confirmed role for this gene in guiding medicine choice or use at this time, so questions about side effects, new symptoms, or whether a treatment is working are best discussed with your doctor.
