Acromelic dysplasias are a group of skeletal dysplasias characterised by short-limbed short stature with other distinctive phenotypic features including small hands and feet and stiff joints. Geleophysic dysplasia is an acromelic dysplasia that is associated with characteristic facial features, progressive cardiac valvular thickening, and tracheal stenosis. Owing to overlapping clinical features with other types of short-limbed skeletal dysplasias, it is important to make a precise diagnosis as they have different cardiac morbidity and mortality. We present the cases of three patients with geleophysic dysplasia and progressive mitral valve disease to emphasise the natural history of this disorder and provide guidance regarding cardiac health supervision in these individuals.

Geleophysic dysplasia is an extremely rare acromelic skeletal dysplasia resembling lysosomal storage disease. It is characterised by characteristic facial phenotype, short stature, micromelia, joint contracture, and early cardiac valvular involvement. It has been described worldwide in <40 patients. Herein, we describe the cardiac features in three Saudi sisters with proved autosomal recessive geleophysic dysplasia who showed different levels of severity of their cardiac involvement.
