The PALMD gene makes a protein that helps cells maintain their shape and organize the outer surface of the cell. This gene plays an important role in how some tissues handle physical stress, so if it does not work properly, normal cell structure and tissue function may be affected. Some variants in or near the PALMD gene have been linked to a higher chance of calcific aortic valve disease, in which the aortic valve becomes stiff and narrow. Most variants in this gene have little effect on health.
What is a gene?
A gene is a piece of DNA that holds instructions your cells use to make molecules or to regulate activities in the body. Some genes provide the directions for proteins, which do much of the work inside cells. Others mainly determine 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 also influence how you respond to food, stress, and medications.

Overview
PALMDGene function
What if the gene works
The PALMD gene helps make a protein called palmdelphin, which supports cell shape and the cell surface membrane. It is active in several tissues, including the heart.
Risk
What if the gene does not work
PALMD variants can range from milder to more severe and may reduce how well cells control membrane shape and their internal support framework. With greater loss of PALMD activity, cell shape changes and movement signals can be disrupted more strongly.
Treatment
What does that mean for your treatment
For a pathogenic or loss-of-function variant in the PALMD gene, no PALMD-specific treatment or management approach is currently established. The PALMD gene is being studied in calcific aortic valve disease to better understand valve biology and possible future drug targets, but this has not changed current drug choices or care.
Gene function
What if the gene works
Your cells use the PALMD gene to help manage their outer surface and overall shape. Its protein can work inside the cell or attach to the cell membrane, where it supports routine structural changes. Understanding how the PALMD gene works in cells helps explain how cells stay flexible while keeping their basic form.
The PALMD gene helps cells keep a stable shape by working with the internal support fibers that give them structure. This support lets cells adjust their form in a controlled way during normal activity.
Its protein can attach to the cell membrane, the thin outer layer around each cell. At the surface, it helps manage small shape changes and extensions that cells use to connect with their surroundings.
What is a variant?
A genetic variant is a small difference in the DNA sequence of 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 have any noticeable effect and simply represent natural genetic variation. In some cases, though, a variant can more substantially change how a gene functions and may contribute to or cause a genetic condition.
Genetic variants
What if the gene does not work
PALMD gene variants may change how much palmdelphin is made, whether the protein keeps its shape, or how well it interacts with other parts of the cell. In explaining how variants influence the PALMD gene's function, milder variants may only partly reduce protein stability, while more severe variants can sharply lower protein levels or prevent a complete protein from being made. This creates a spectrum of cellular effects rather than one fixed outcome.
How variants are linked to conditions
Variants in the PALMD gene do not yet have a broadly confirmed link to a specific health condition, although research on PALMD gene variants and disease is still developing. If you have a confirmed PALMD-related diagnosis, your doctor or genetic counselor can explain what that result may mean for your health and family.
A variant is not necessarily a diagnosis
Genetic variants are common across the general population and are a normal feature of human biology. Most do not directly affect health and simply reflect natural variation among people. For many genes, having a variant associated with a condition suggests a possible link rather than a certain diagnosis, particularly when several genes and environmental influences play a role. In other 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?
Changes near the PALMD gene have been linked with a higher chance of calcific aortic valve disease, a condition where the heart valve becomes stiff over time. Risk is also shaped by age, smoking, high blood pressure, high cholesterol, diabetes, and kidney disease. A PALMD-related variant does not mean someone will definitely develop valve disease.
Inheritance of PALMD variants
There is not yet a broadly confirmed Mendelian pattern for how PALMD gene variants are inherited in relation to a specific PALMD related condition. Current research links the PALMD gene to some health traits and risks, but not in a way that supports a clear autosomal dominant or autosomal recessive pattern. For people looking into how PALMD gene variants are inherited, it helps to know that the PALMD gene is located on chromosome 1, which is an autosome. That means you inherit one copy of the PALMD gene from your mother and one copy from your father.
What does my PALMD result mean for my family?
There is not yet a broadly confirmed inherited pattern tied to a specific PALMD-related condition in the way seen with some well-known single-gene conditions. If you have a PALMD result and want to know what it could mean for relatives, the meaning usually depends on the exact change found and the health condition being looked at.
Genetic information
Genetic testing
How you find out about variants
To find out whether you carry a variant in the PALMD gene, a genetic test checks DNA from saliva or blood. Genetic testing for PALMD variants usually uses sequencing to read the gene's code and report whether a variant was found, although the result does not always predict symptoms on its own.
When should I consider getting a genetic test?
There is not yet a broadly established reason to test the PALMD gene on its own in routine care. Decisions about genetic testing are usually based on your personal health and family history, especially if there is early or unexplained heart valve disease.
A genetic result is only one part of your health story
Genetic findings can offer useful insight, but how much they reveal depends on the condition and on the type of variant involved. The way the body functions over time is 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 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. This is one reason the same medication may work well for one person, seem less effective for another, or cause more side effects in someone else. Small differences in the genes involved in how the body absorbs, breaks down, or responds to a drug are common and can influence both treatment benefit and sensitivity.
What is Pharmacogenetics?
Pharmacogenetics examines how genetic differences shape a person’s response to medications. It studies the relationship between genes and drugs to help explain why the same treatment can work differently from one person to another. For many medicines, genes affect both how strongly a drug works and how the body handles it. This information can support treatment decisions that are better informed and more individualized.

Drugs influenced by the PALMD gene
When should I seek medical advice?
There is not yet a broadly confirmed role for this gene in guiding medication choices, so any questions about side effects, new symptoms, or whether a treatment is working as expected are best discussed with your doctor.
