The ADAMTSL2 gene helps organize connective tissue, the material that supports skin, bones, joints, heart valves, and airways. When both copies of this gene do not work properly, a person can develop geleophysic dysplasia, a rare condition linked to short stature, stiff joints, thick skin, and breathing or heart problems. The protein made by this gene helps your cells manage signals that guide growth and tissue structure. Because these changes are inherited, genetic results can help confirm the diagnosis in affected families.
What is a gene?
A gene is a piece of DNA that carries instructions your cells can use to make molecules or direct processes in the body. Some genes hold the instructions for making proteins, the parts of cells that do the work. Other genes mainly help control when certain processes happen, where they happen, and how active they are. Together, genes influence how the body develops and functions, and they can also shape how you respond to food, stress, or medications.

Overview
ADAMTSL2Gene function
What if the gene works
The ADAMTSL2 gene helps build and organize connective tissue, the material that supports skin, joints, airways, and other organs. It also helps control growth signals between cells.
Risk
What if the gene does not work
More disruptive variants in the ADAMTSL2 gene can cause geleophysic dysplasia, a condition affecting growth and connective tissues. Features often include short stature, stiff joints, and sometimes breathing or heart valve problems, with severity varying by variant.
Treatment
What does that mean for your treatment
No ADAMTSL2-specific treatment or drug selection approach is currently established, so care is guided by symptoms and complications rather than the ADAMTSL2 gene itself.
Conditions associated with ADAMTSL2
Gene function
What if the gene works
Connective tissue gives skin, airways, blood vessels, and other organs their supportive framework. The ADAMTSL2 gene helps build and organize this framework outside cells. Understanding ADAMTSL2 gene function helps explain how tissues keep their shape and how cells receive steady mechanical and chemical cues.
The ADAMTSL2 gene makes a protein that is released into the space around cells. There, it becomes part of the extracellular matrix, the supportive material that helps tissues stay connected and resilient.
Its protein attaches to partners such as fibrillin 1, a major connective tissue protein. These links help organize fine elastic strands around cells, so tissues can keep a stable structure during everyday movement and growth.
Its protein also helps manage how growth signals are held and released in the matrix around cells. This supports balanced cell communication as tissues develop, renew themselves, and respond to normal physical stress.
What is a variant?
A genetic variant is a minor change in the DNA sequence within a gene. These changes are common and help shape normal human diversity, including differences 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 can change how a gene functions more substantially and may contribute to, or cause, a genetic condition.
Genetic variants
What if the gene does not work
Many ADAMTSL2 gene variants change how the protein is folded, processed, or released from the cell, so ADAMTSL2 gene variants can reduce protein function before it reaches the tissue around cells. Some variants also weaken its interactions with nearby structural proteins and may disturb growth-factor signaling (chemical messages that guide cell behavior). Milder variants may leave some residual activity, while more severe variants can leave very little working protein. In people with ADAMTSL2-related geleophysic dysplasia, that difference can influence how early features appear and how marked they are.
How variants are linked to conditions
Pathogenic variants in the ADAMTSL2 gene are linked to geleophysic dysplasia, a rare inherited condition that often involves short stature, stiff joints, and narrowing in the heart valves or airways. In people with matching symptoms, finding disease-causing changes in both copies of the ADAMTSL2 gene can confirm the diagnosis. This ADAMTSL2 gene condition is the main well-established association reported in human genetics.
A variant is not necessarily a diagnosis
Genetic variants are a common and normal feature of human biology across the general population. Most do not directly affect health and instead represent part of normal human diversity. For many genes, having a variant associated with a condition points to a possible link rather than a certain diagnosis, particularly when several genes and environmental influences both play a role. In some situations, though, one well-characterized variant in a particular gene is enough to confirm the diagnosis.
Are there things that can increase or change my risk?
For ADAMTSL2, risk is mainly shaped by inheritance rather than lifestyle. A child is at highest risk when both parents carry a disease-causing ADAMTSL2 variant; in that case, each pregnancy has a 25% chance of the child inheriting the condition.
Inheritance of ADAMTSL2 variants
ADAMTSL2-related conditions are inherited in an autosomal recessive pattern. This means a child usually inherits one ADAMTSL2 gene variant from each parent, and parents are typically healthy carriers who each have one altered copy and one working copy. When both parents carry an ADAMTSL2 gene variant, each pregnancy has a 25% chance of being affected, a 50% chance of producing a carrier child, and a 25% chance of producing a child with neither variant. In practical terms, how ADAMTSL2 gene variants are inherited depends on both parents passing on the altered copy.
What does my ADAMTSL2 result mean for my family?
ADAMTSL2-related health conditions are usually passed down in a recessive pattern, so family members may be healthy carriers without knowing it. Brothers and sisters of someone with an ADAMTSL2-related condition may also be affected or may be carriers. Parents are usually carriers, and other close relatives may want to learn whether they also carry the family’s gene change.
Genetic information
Genetic testing
How you find out about variants
To look for changes in the ADAMTSL2 gene, doctors use genetic testing for ADAMTSL2 variants, usually with a blood sample or saliva. A lab reads the gene’s DNA sequence and checks whether a variant matches a known disease causing change, a harmless difference, or a result that needs more review.
When should I consider getting a genetic test?
Genetic testing for the ADAMTSL2 gene may be considered when a child has signs of a rare growth and bone condition such as very short height, stiff joints, small hands and feet, or unexplained heart or airway problems. It can also help when this condition runs in the family or when parents are known carriers.
A genetic result is only one part of your health story
Genetic results can provide useful insight, but how much they reveal varies by the condition and the specific type of variant. How the body functions over time is also shaped by many factors, including lifestyle, environment, age, and medical history. For some conditions, especially those affected by many genes, genetic information provides context rather than certainty and is most helpful when viewed 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 individual experiences into context.
Pharmacogenetics
How variants shape your response to medicine
Genetic variation can affect how people respond to medicines. Small differences in genes can change how the body breaks down a drug, moves it through the body, or responds to it 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 who is more sensitive to it.
What is Pharmacogenetics?
Pharmacogenetics examines how inherited genetic differences can affect a person’s response to medications. It looks at gene-drug relationships 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 processes it. This information can help support more informed, individualized treatment decisions. More on this topic is available in the LearnHub.
Drugs influenced by the ADAMTSL2 gene
When should I seek medical advice?
There is not yet a broadly confirmed role for this gene in predicting how people respond to medicines. If you have side effects, trouble with a treatment, or questions about how your medicines fit with your health condition, talk with your doctor.
History
Throughout history, people have described features that hinted at this gene. People with the condition now called geleophysic dysplasia were first recognized from their physical features, years before the ADAMTSL2 gene was identified. In 2008, researchers linked pathogenic variants in the ADAMTSL2 gene to this rare inherited condition, which marked an important step in clarifying its genetic basis. From these first observations, research expanded steadily, and later reports showed that changes in the ADAMTSL2 gene could be associated with a range of findings and overlap with related skeletal conditions. This history helped move diagnosis from appearance alone to more precise genetic confirmation.
