Your cells depend on the ZDHHC23 gene when they need to attach small fat tags to certain proteins, a step that helps those proteins reach the right place in the cell and work properly. If the gene does not work as expected, some proteins may be misplaced or signal less effectively, which can disturb normal cell communication. This seems especially relevant in tissues that rely on finely tuned signaling, including the brain. ZDHHC23 is mainly known in research and has not become a widely recognized public interest gene.
What is a gene?
Genes are stretches of DNA that give your cells instructions they use to make molecules or direct processes in the body. Some carry the directions for producing proteins, which are the working parts of cells. Others mainly regulate the timing, location, and strength of certain processes. Together, genes affect how the body develops and functions, and they can influence how you respond to food, stress, and medications. For a closer look at this topic, you can read more in the LearnHub.
Overview
ZDHHC23Gene function
What if the gene works
The ZDHHC23 gene helps cells attach a small fat tag to certain proteins. This helps guide where those proteins work and how cells handle signals.
Risk
What if the gene does not work
Changes in the ZDHHC23 gene may reduce the cell’s ability to attach fatty acid tags to certain proteins, which can alter where they work. Milder variants may leave some activity, while more severe variants can cause greater loss of function.
Treatment
What does that mean for your treatment
At present, no treatment or drug choice is guided specifically by pathogenic or loss-of-function variants in the ZDHHC23 gene.
Gene function
What if the gene works
Your cells use the ZDHHC23 gene to help certain proteins settle into the right membrane and do their jobs. Its main task, and the core of the ZDHHC23 gene's function in cells, is adding a small fatty tag to selected proteins. This can help them stick to membranes, move within the cell, and pass along signals.
The protein from the ZDHHC23 gene adds a small fatty tag to selected proteins. This tag helps them attach to cell membranes, where many cell jobs happen.
Some proteins need this tag to reach the right spot inside the cell. The ZDHHC23 gene helps position them so they can work where they are needed.
Membrane proteins often rely on correct placement to send or receive signals. By supporting that placement, the ZDHHC23 gene helps everyday cell signaling stay organized.
What is a variant?
A genetic variant is a small difference in the DNA sequence within a gene. These changes are common and are one reason for normal human diversity, including differences in appearance, metabolism, or how the body responds to environmental influences. Many variants do not have any noticeable effect 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
Research on how variants in the ZDHHC23 gene affect protein function shows that some changes can weaken the enzyme's ability to attach fatty acid tags to target proteins or disturb its placement in cell membranes. Small single-letter changes may leave some activity intact, while more disruptive variants that shorten the protein or alter its DHHC working site can substantially reduce stability, activity, or interactions with partner proteins.
How variants are linked to conditions
Variants in the ZDHHC23 gene do not yet have a broadly confirmed link to a specific health condition, and research on ZDHHC23 gene variants and health conditions is still developing. Anyone with a confirmed variant in the ZDHHC23 gene should rely on guidance from their doctor or genetic counselor rather than general information.
A variant is not necessarily a diagnosis
Genetic variants are a usual part of human biology and are frequent in the general population. Most do not have a direct effect on health and instead reflect normal human diversity. For many genes, carrying a variant associated with a condition suggests a possible link rather than a confirmed diagnosis, particularly when several genes and environmental factors are also involved. In some situations, though, a single well-characterized variant in a specific 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 ZDHHC23 gene. People with concerns about their personal or family risk can discuss this with a doctor or genetic counselor.
Inheritance of ZDHHC23 variants
There is not yet a broadly confirmed inheritance pattern tied to a specific ZDHHC23-related condition, so how ZDHHC23 gene variants are inherited in a disease setting is still being worked out. ZDHHC23 is located on an autosome, which means each person inherits one copy of the ZDHHC23 gene from each parent. In general, variants in autosomal genes can be passed from either parent to a child.
What does my ZDHHC23 result mean for my family?
There is not yet a broadly confirmed inheritance pattern tied to a specific health condition for the ZDHHC23 gene, though this can change as research develops. If you have a specific ZDHHC23 result and questions about what it could mean for your family, a doctor or genetic counselor can help explain it in the context of your personal and family history.
Genetic information
Genetic testing
How you find out about variants
To look for changes in the ZDHHC23 gene, a lab can analyze DNA from a blood sample, saliva, or a cheek swab. This is how genetic testing for ZDHHC23 variants works: the lab reads the gene’s sequence and checks for differences in the DNA code. Results may show a benign variant, a variant of uncertain significance, or one linked to disease.
When should I consider getting a genetic test?
There isn't yet a broadly established, ZDHHC23-specific clinical reason for genetic testing. Testing decisions are usually based on your symptoms and family history, together with a doctor or genetic counselor.
A genetic result is only one part of your health story
Genetic results can provide useful insight, but how much they explain varies by the condition and the kind of variant involved. Over time, many factors influence how the body functions, including lifestyle, environment, age, and medical history. In some conditions, especially those shaped by many genes, genetic information provides context rather than certainty and is most helpful when viewed together with other parts of care. In other situations, a genetic result can 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 influence how your body handles medicines, so the same treatment may not work the same way for everyone. Small differences in genes can affect how quickly a drug is broken down, how it moves through the body, or how strongly it acts at its target. This is a common part of human biology and can shape both how well a medicine helps and how sensitive someone is to side effects.
What is Pharmacogenetics?
Pharmacogenetics examines how inherited genetic differences can affect the way someone responds to medication. It studies the relationship between genes and medicines to help explain why the same treatment may work differently in different people. With many drugs, genes influence both how powerfully a medicine works and how the body handles it. This information can support more personalized and well-informed treatment choices. More detail on this topic is available in the LearnHub.
Drugs influenced by the ZDHHC23 gene
When should I seek medical advice?
There is not yet a broadly confirmed role for this gene in predicting how medicines will work, so any concerns about side effects, treatment changes, or new symptoms are best discussed with your doctor.
