The ADAMTSL5 gene makes a protein that is released outside cells, where it helps organize the supportive material around them, especially in the skin. If this gene does not work as expected, the structure and communication of these tissues may change. This gene plays an important role in the skin because the ADAMTSL5 protein can also become a target of the immune system in some people with psoriasis.
What is a gene?
Genes are segments of DNA that provide cells with instructions to make molecules or regulate processes in the body. Some genes hold the information needed to build proteins, the parts of cells that carry out much of the work. Other genes mainly control when certain processes happen, where they happen, and how strongly they operate. Together, genes affect how the body develops and functions, and they can also influence how you respond to food, stress, or medications.

Overview
ADAMTSL5Gene function
What if the gene works
The ADAMTSL5 gene helps make a protein released outside cells. This protein supports the material around cells that helps give skin and other tissues structure.
Risk
What if the gene does not work
Changes in the ADAMTSL5 gene can range from milder to more severe variants, which may reduce how well its protein supports the material around cells and interacts with other proteins outside cells.
Treatment
What does that mean for your treatment
No ADAMTSL5-specific treatment or management approach is currently established for people with a pathogenic variant in the ADAMTSL5 gene. The ADAMTSL5 gene is being studied mainly in psoriasis research as an immune target and possible biomarker, rather than as a guide for current drug choice.
Gene function
What if the gene works
Much of your body’s support system sits outside cells, where proteins help tissues keep their shape. The ADAMTSL5 gene gives instructions for one of these proteins. In everyday terms, what the ADAMTSL5 gene does in the body is help build and organize the outer scaffold around cells, especially fibrillin rich fibers in connective tissue.
Its protein is released into the space around cells instead of staying inside them. There it becomes part of the extracellular matrix, the material that supports and organizes tissues.
One of its main jobs is to attach to fibrillin proteins, which are building blocks of tiny support fibers called microfibrils. This helps those fibers form in an orderly way.
By helping organize microfibrils, the ADAMTSL5 gene supports the normal structure of connective tissue. This can help tissues stay steady and flexible during everyday stretching and movement.
What is a variant?
A genetic variant is a small difference in the DNA sequence of a gene. These differences are common and are part of normal human diversity, including variation in appearance, metabolism, and the way 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 changes how a gene works more substantially and can contribute to or cause a genetic condition.
Genetic variants
What if the gene does not work
Variants in the ADAMTSL5 gene can change the shape of its protein, making it less stable, less efficiently released from the cell, or less able to bind its usual partners outside the cell. In plain terms, how ADAMTSL5 variants affect protein stability and secretion depends on the specific DNA change. Some are milder and only partly reduce function, while more disruptive variants may lead to little or no working protein.
How variants are linked to conditions
Current evidence does not yet show a broadly confirmed link between the ADAMTSL5 gene and a specific health condition. Information on ADAMTSL5 gene variants and health conditions may change as research develops, so anyone with a confirmed diagnosis involving the ADAMTSL5 gene should follow guidance from their doctor or genetic counselor.
A variant is not necessarily a diagnosis
Genetic variants are a usual part of human biology and are widespread in the general population. Most do not have a direct effect on health and simply contribute to natural human diversity. For many genes, having a variant associated with a condition suggests a possible link rather than a definite diagnosis, particularly when multiple genes and environmental factors are involved. In some situations, though, a single well characterized variant in a specific 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 risk related to the ADAMTSL5 gene itself. If ADAMTSL5 comes up in your results, a doctor or genetic counselor can help put it in context with your personal and family health history.
Inheritance of ADAMTSL5 variants
There is not yet a broadly confirmed Mendelian inheritance pattern for disease linked specifically to the ADAMTSL5 gene, so ADAMTSL5 inheritance is not described as clearly autosomal dominant, autosomal recessive, or X linked at this time. The ADAMTSL5 gene is located on chromosome 19, which is an autosome, so you inherit one copy from each parent. Any health effects tied to ADAMTSL5 are currently understood in a more complex way than a single, well-established family pattern.
What does my ADAMTSL5 result mean for my family?
There is not yet a broadly confirmed family inheritance pattern tied to a specific health condition for the ADAMTSL5 gene, and research is still developing. If you have a specific ADAMTSL5 result, a doctor or genetic counselor can help explain what it may or may not mean for close relatives.
Genetic information
Genetic testing
How you find out about variants
To learn how genetic testing finds ADAMTSL5 variants, a lab reads the DNA sequence from a blood, saliva, or cheek swab sample and compares it with the usual sequence. Results may show a variant in the ADAMTSL5 gene, no relevant variant, or a variant of uncertain significance, meaning its health effect is not yet clear.
When should I consider getting a genetic test?
There is not yet a broadly established medical reason to order testing specifically for the ADAMTSL5 gene. Decisions about genetic testing are usually based on your own health history and family history and are best discussed with a doctor or genetic counselor.
A genetic result is only one part of your health story
A genetic result can be informative, but how much it reveals depends on the condition and the specific type of variant. Over time, the way the body works is also shaped by factors such as 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 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 help put individual experiences into context.
Pharmacogenetics
How variants shape your response to medicine
Genetic variation can affect how people respond to medicines because the body does not handle every drug in exactly the same way. Small differences in genes can change how a medicine is absorbed, broken down, moved through the body, or how strongly it acts on its target. This is common and can help explain why the same treatment works well for one person, works less well for another, or causes more side effects in someone else.
What is Pharmacogenetics?
Pharmacogenetics examines how differences in a person’s genes affect the way they respond to medications. It studies gene drug relationships to help explain why the same treatment can have different effects in different people. With many medicines, genes can influence both how powerfully a drug works and how the body handles it. This information can support treatment choices that are better informed and more individualized. More detail on this topic is available in the LearnHub.
Drugs influenced by the ADAMTSL5 gene
When should I seek medical advice?
There is not yet a broadly confirmed role for this gene in guiding medication choices, so general concerns about treatment, side effects, or how well a medicine is working are best discussed with your doctor. Seek medical advice if symptoms change, side effects start, or you are worried about how a treatment is affecting you.
