The FKBP10 gene helps your body fold and organize collagen, a protein that gives bones and other tissues strength. If this gene does not work properly, collagen may be weaker, which can lead to bones that break more easily, spine curvature, joint stiffness, and short stature. This gene plays an important role in healthy bone development, so some people with harmful variants are diagnosed with osteogenesis imperfecta or Bruck syndrome.
What is a gene?
Genes are sections of DNA that carry instructions your cells use to make molecules or regulate processes in the body. Some genes provide the information for making proteins, the working parts of cells. Others mainly help direct when certain processes happen, where they take place, and how strongly they run. Together, genes affect how the body develops and works, and they can influence how you respond to food, stress, and medications. More on this topic is available in the LearnHub.
Overview
FKBP10Gene function
What if the gene works
The FKBP10 gene helps cells fold and prepare collagen correctly. This supports strong bone and connective tissue, including tendons and ligaments.
Risk
What if the gene does not work
Variants in the FKBP10 gene can cause brittle bones with repeated fractures and sometimes joint contractures. Milder to more severe variants may influence how early symptoms appear and how marked the bone and movement problems become.
Treatment
What does that mean for your treatment
No treatment or management approach specific to the FKBP10 gene is currently established. Care is guided by bone and joint needs, using standard supportive treatment rather than drug choices based on the FKBP10 gene. The FKBP10 gene is also being studied as a possible biomarker and drug target in some cancers and fibrotic diseases.
Conditions associated with FKBP10
Gene function
What if the gene works
Collagen gives many tissues their basic framework and strength. Your cells rely on the FKBP10 gene to help build well-formed collagen, one of the body's main support proteins. Knowing what the FKBP10 gene does helps explain how bone, skin, tendons, and ligaments keep their usual structure.
Inside the cell's protein processing area (endoplasmic reticulum), the FKBP10 gene helps new collagen chains bend and fold into the right shape. This gives collagen a stable form that can move on to later building steps.
This gene provides instructions for a helper protein that guides collagen as it is assembled and prepared to leave the cell. That steady handling helps cells manage a large, rope-like material without tangling.
The protein made from the FKBP10 gene supports finishing steps that help collagen molecules line up and link together into sturdy fibers. These fibers give connective tissues their usual framework in places such as bone, skin, and tendons.
What is a variant?
A genetic variant is a small difference in the DNA sequence of a gene. These changes are common and help create normal human diversity, such as differences in appearance, metabolism, or how the body responds to environmental influences. Many have no noticeable effect and simply represent natural genetic variation. In some cases, though, a variant can change how a gene functions to a greater extent and may contribute to or cause a genetic condition.
Genetic variants
What if the gene does not work
Many variants in the FKBP10 gene leave cells with too little working FKBP65 protein or a misshapen, unstable version, so collagen is folded and linked less effectively. These FKBP10 variant effects on collagen processing can range from mild to marked, depending on whether some protein activity remains. Variants that largely switch the gene off often have a stronger functional impact and are linked to earlier or more noticeable bone fragility and joint tightening.
How variants are linked to conditions
Pathogenic variants in the FKBP10 gene cause some inherited bone conditions, especially FKBP10 gene osteogenesis imperfecta and Bruck syndrome type 1. These conditions are linked to fragile bones, repeated fractures, short stature, and sometimes stiff joints or contractures present from childhood. A person usually has the condition when pathogenic variants are present in both copies of the FKBP10 gene.
A variant is not necessarily a diagnosis
Genetic variants are a usual part of human biology and are widely found in the general population. Most do not directly affect health and instead reflect normal human diversity. For many genes, having a variant associated with a condition indicates a possible link rather than a certain diagnosis, especially when several genes and environmental influences play a role. In some situations, though, a single well-characterized variant in a particular gene is enough to confirm a diagnosis.
Are there things that can increase or change my risk?
For FKBP10-related conditions, risk is mainly shaped by whether someone inherits disease-causing changes in both copies of the FKBP10 gene. There is not enough evidence that diet, exercise, or other lifestyle factors change whether the condition develops, though fall prevention and good bone care can help reduce fractures and other complications.
Inheritance of FKBP10 variants
Variants in the FKBP10 gene are inherited in an autosomal recessive pattern. This means a person usually inherits one altered copy from each parent, and both parents are typically healthy carriers. For each pregnancy, two carrier parents have a 25% chance of having a child with an FKBP10 related condition, a 50% chance of having a carrier child, and a 25% chance of having a child without the family variant. In practical terms, FKBP10 gene inheritance affects males and females equally because this gene is on chromosome 17, which is an autosome.
What does my FKBP10 result mean for my family?
For families with a disease-causing FKBP10 result, this condition is usually passed down in a recessive pattern. That often means parents are healthy carriers, and brothers or sisters may also be affected or be carriers. Other relatives on either side of the family may be carriers too, especially if the same result is found in more than one family member.
Genetic information
Genetic testing
How you find out about variants
To find out whether you carry a variant in the FKBP10 gene, FKBP10 genetic testing uses a blood or saliva sample to read the gene’s DNA code. A lab looks for changes in the sequence and reports whether a variant was found, which can help clarify whether FKBP10 is involved.
When should I consider getting a genetic test?
Consider testing for the FKBP10 gene if there is a history of frequent fractures from mild injuries, brittle bones, spine curvature, or joint stiffness from childhood, especially if it runs in the family. Testing can help confirm the cause of these bone problems and clarify whether relatives may also carry the gene change.
A genetic result is only one part of your health story
A genetic result can provide valuable insight, but how much it can tell you varies by the condition and the type of variant involved. Over time, many factors, including lifestyle, environment, age, and medical history, shape how the body functions. In some conditions, especially those influenced by many genes, genetic information provides context rather than certainty and is most useful when considered alongside 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 individual experiences into context.
Pharmacogenetics
How variants shape your response to medicine
Genetic variation can affect how people respond to medicines, which is one reason the same treatment may help one person more than another. Small differences in genes can change how the body absorbs, breaks down, transports, or responds to a drug. This is common and can influence how well a medicine works or how likely someone is to notice side effects or stronger sensitivity to treatment.
What is Pharmacogenetics?
Pharmacogenetics examines how genetic differences can shape the way a person responds to medications. By looking at the relationship between genes and drugs, it helps explain why the same treatment can work differently from one person to another. For many medicines, genes affect both how the body processes a drug and how strong its effects are. This information can support treatment decisions that are more informed and more individualized. More information about this topic is available in the LearnHub.
Drugs influenced by the FKBP10 gene
When should I seek medical advice?
There is not yet a broadly confirmed role for this gene in guiding medication choice or dose, so any questions about medicines, side effects, or your health are best discussed with your doctor.
History
Throughout history, people have described families with fragile bones and joint contractures, though the genetic cause was not yet known. In the late 2000s and early 2010s, researchers linked some of these inherited bone conditions to the FKBP10 gene, especially in people diagnosed with recessive forms of osteogenesis imperfecta and Bruck syndrome. From these first observations, research expanded steadily, helping doctors see that similar bone conditions could arise from different genes. This discovery broadened the genetic picture of brittle bone conditions and improved how some families were classified. Over time, scientists’ understanding of the FKBP10 gene’s place in inherited bone disease has become more precise.
