Original Investigations


This paper describes 3 infants with a severe, generalized chondrodysplasia with short limbs, shortness of stature, relative micrognathia and neonatal respiratory distress in all cases, cleft palate in two and dislocation of lenses in one. They diet at 7 and 10 weeks and at 17 months respectively. No autopsy was performed on any of the 3 patients. Roentgenological manifestations include short, broad tubular bones with metaphyseal widening, bowing of leg, thigh and forearm bones, neonatal accelerated carpal bone maturation, short, broad pelvis with wide, flared iliac wings, many gross vertebral abnormalities including most prominently coronal clefts of almost any vertebral body, and short ribs with flared anterior ends. Roentgenographically the condition has some similarities with Kniest disease, or more correctly, the Kniest chondrodysplasia. However, we think that the clinical and roentgenological manifestations are sufficiently unique to permit delineation of the condition of our 3 patients as a “new” entity different from the Kniest chondrodysplasia. Similar cases have been described by Rolland et al. from France and by Dinno et al. from the U.S.A. The latter case and our 3 patients were sporadic cases, but the former had a probably affected sibling, suggesting that this disorder is an autosomal recessive trait.
