Disease Profile

Jeune syndrome

Prevalence estimates on Rare Medical Network websites are calculated based on data available from numerous sources, including US and European government statistics, the NIH, Orphanet, and published epidemiologic studies. Rare disease population data is recognized to be highly variable, and based on a wide variety of source data and methodologies, so the prevalence data on this site should be assumed to be estimated and cannot be considered to be absolutely correct.

Age of onset





Autosomal dominant A pathogenic variant in only one gene copy in each cell is sufficient to cause an autosomal dominant disease.


Autosomal recessive Pathogenic variants in both copies of each gene of the chromosome are needed to cause an autosomal recessive disease and observe the mutant phenotype.


dominant X-linked dominant inheritance, sometimes referred to as X-linked dominance, is a mode of genetic inheritance by which a dominant gene is carried on the X chromosome.


recessive Pathogenic variants in both copies of a gene on the X chromosome cause an X-linked recessive disorder.


Mitochondrial or multigenic Mitochondrial genetic disorders can be caused by changes (mutations) in either the mitochondrial DNA or nuclear DNA that lead to dysfunction of the mitochondria and inadequate production of energy.


Multigenic or multifactor Inheritance involving many factors, of which at least one is genetic but none is of overwhelming importance, as in the causation of a disease by multiple genetic and environmental factors.

Jeune syndrome is a rare condition that primarily affects the bones. Common signs and symptoms include a small chest and short ribs which restrict the growth and expansion of the lungs, often causing life-threatening breathing difficulties. Other symptoms may include shortened bones in the arms and legs, unusually shaped pelvic bones, and extra fingers and/or toes. People who survive the breathing challenges of infancy, may later develop severe kidney or heart problems.[1][2] In many cases the cause of Jeune syndrome is unknown; however, changes (mutations) in several different genes (IFT80, DYNC2H1, WDR19, IFT140 and TTC21B) have been identified in some families with the condition. Jeune syndrome is inherited in an autosomal recessive manner. Treatment is based on the signs and symptoms present in each person.[2][3]


Jeune syndrome is a rare condition that primarily affects the bones. People affected by this condition are typically born with skeletal abnormalities such as:[1][2]

  • Small, narrow chest
  • Short ribs
  • Shortened bones of the arms and legs
  • Unusually shaped pelvis
  • Extra fingers and/or toes

Because of the chest and rib abnormalities (which lead to a characteristic "bell-shaped" chest cavity), babies with Jeune syndrome often develop life-threatening breathing difficulties. As a result, many affected people do not live past infancy or early childhood.[1]

Less commonly, Jeune syndrome is associated with only mild breathing problems which allow for survival into adolescence or early adulthood. However, those that live past infancy may experience severe health problems of the kidney and/or heart.[1]

Other features of Jeune syndrome include high blood pressure, liver disease, pancreatic cysts, dental abnormalities, and an eye disease called retinal dystrophy that can lead to vision loss.[1][2]

This table lists symptoms that people with this disease may have. For most diseases, symptoms will vary from person to person. People with the same disease may not have all the symptoms listed. This information comes from a database called the Human Phenotype Ontology (HPO) . The HPO collects information on symptoms that have been described in medical resources. The HPO is updated regularly. Use the HPO ID to access more in-depth information about a symptom.

In many cases, the cause of Jeune syndrome is unknown. However, changes (mutations) in several different genes (IFT80, DYNC2H1, WDR19, IFT140 and TTC21B) have been identified in some families with the condition. These genes all provide instructions for making a protein that is found in cell structures called cilia, which are microscopic, finger-like projections on the surface of cells. Tt is unclear how mutations that disrupt the development and maintenance of cilia lead to the signs and symptoms associated with Jeune syndrome.[2]


In some cases, a diagnosis of Jeune syndrome may be suspected before birth if characteristic signs and symptoms are present on ultrasound. After birth, Jeune syndrome is based on X-ray findings. In some families, the diagnosis can be confirmed with genetic testing.[2][3]

Testing Resources

  • The Genetic Testing Registry (GTR) provides information about the genetic tests for this condition. The intended audience for the GTR is health care providers and researchers. Patients and consumers with specific questions about a genetic test should contact a health care provider or a genetics professional.
  • Orphanet lists international laboratories offering diagnostic testing for this condition.


    The treatment of Jeune syndrome is based on the signs and symptoms present in each person. Most people with Jeune syndrome experience breathing difficulties that may become more severe over time due to multiple respiratory infections. In very severe cases, mechanical ventilation may be necessary shortly after birth and surgical interventions (i.e. chests reconstruction) may be recommended. In those who are less severely affected, respiratory infections should be aggressively managed to prevent or delay respiratory failure.[2][3]

    Dialysis and renal transplantation may be indicated for people with kidney problems.[2]

    Support and advocacy groups can help you connect with other patients and families, and they can provide valuable services. Many develop patient-centered information and are the driving force behind research for better treatments and possible cures. They can direct you to research, resources, and services. Many organizations also have experts who serve as medical advisors or provide lists of doctors/clinics. Visit the group’s website or contact them to learn about the services they offer.
