Jeune Syndrome, also known as asphyxiating thoracic dystrophy, is a rare, severe, inherited disorder characterized by abnormal bone and cartilage development. The condition causes a severely small and rigid rib cage, which restricts lung growth and leads to breathing difficulty.

This genetic defect prevents proper bone and cartilage formation, resulting in the characteristic short, narrow, and bell-shaped chest wall (thoracic cage). This severe restriction is congenital (present at birth) and restricts the lungs. The abnormal development of the ribs and lungs is what defines the severity of the syndrome and its prognosis.
Symptoms are associated with chronic respiratory insufficiency. Infants experience severe, rapid breathing and difficulty feeding due to the restricted chest capacity. The most severe problem is that the constricted rib cage cannot expand properly, leading to inadequate lung development and failure to breathe effectively. Skeletal issues include short limbs, small stature, and sometimes kidney or liver abnormalities. This combination of structural and respiratory defects makes the condition life-threatening in infancy.
Jeune Syndrome can impact vision due to associated organ failure. Patients may develop severe retinal degeneration, which progresses over time and can cause vision loss. Additionally, the renal (kidney) and liver problems associated with the syndrome can lead to systemic complications that affect the health of the eye's vascular system.
Management focuses on addressing the severe respiratory distress. Interventions include surgical procedures to expand the chest wall, allowing more room for the lungs to grow and breathe. Respiratory support (ventilators) and aggressive treatment of lung infections are also necessary. Kidney function is monitored closely as renal problems are common.
Genetic counseling is necessary for affected families. Counseling helps parents understand the autosomal recessive inheritance pattern and the high risk of recurrence in future pregnancies.
No, the underlying genetic and skeletal defects are permanent, but surgical expansion can improve breathing.
The prognosis is guarded. Respiratory failure is a major cause of death in infancy, but survivors often live into adulthood.
No, Jeune Syndrome is a skeletal disorder and does not typically affect cognitive development.
Infants with a small, bell-shaped chest require immediate pediatric pulmonary evaluation. Jeune Syndrome is associated with "Retinitis Pigmentosa." Regular eye exams are necessary to monitor for early retinal changes that can lead to night blindness.
