Abstract

Background: Persistent, treatment-refractory wheeze in infancy should prompt evaluation for structural and genetic disorders.


Objective: Jeune syndrome (asphyxiating thoracic dystrophy) is a rare ciliopathy characterized by narrow thorax and multisystem involvement.


Methods: We report a 16-month-old boy with recurrent wheeze; clinical, imaging, and genetic data were analyzed.


Results: The patient exhibited narrow thorax, persistent obstructive physiology, nystagmus, bilateral renal cysts, coarse liver parenchyma and pulmonary hypertension. CNV analysis was negative; gene panel sequencing identified a pathogenic variant consistent with a ciliopathy.


Conclusion: Multidisciplinary assessment and early genetic testing are essential in infants with persistent wheeze and extra-pulmonary features.
