GELEOPHYSIC DYSPLASIA - A STORAGE DISORDER AFFECTING THE SKIN, BONE, LIVER, HEART, AND TRACHEA

Geleophysic dysplasia is characterized by typical facles ("happy natured"), small hands and feet, short stature, hepatomegaly, and progressive cardiac disease. We describe five patients (two of whom are siblings) with this disorder and document its variable expressivity. The facies were strikingly similar with small nose, anteverted nostrils, broad nasal bridge, and long thin upper lip with flat and long philtrum. Behavior, development, and intelligence were normal. Growth delay was noticed during infancy, and the two patients who completed normal puberty had marked short stature (140 and 150 cm), with relatively lean body habitus. The hands and feet were small, with short, plump tubular bones and broad proximal phalanges, associated with marked limitation in motion of fingers and wrists. The liver was enlarged after the age of 3 years. Two patients had mild mitral and tricuspid valve stenosis and one had severe aortic stenosis. The most severely affected child died at 3 1/2 years of age of airway obstruction as a result of progressive tracheal narrowing. Lysosomal storage vacuoles were found in skin epithelial cells from three patients whose skin was examined, and in the tracheal mucosa, liver, cartilage and macrophages of the child who died. The basic defect of this autosomal recessive lysosomal storage disease remains to be determined. © 1990 Mosby-Year Book, Inc.
